# Supply

At Yei Finance, depositing assets into our lending pool allows you to earn interest. Simultaneously, these assets act as collateral, enabling the borrowing of additional assets.

### **How to Supply Assets?**

To start supplying assets at Yei Finance, first access the dashboard where you can manage your assets and monitor your earnings. Follow these straightforward steps:

1. **Access the Dashboard:** Visit the Yei Finance platform and navigate to the dashboard. This is your hub for asset management and tracking returns.

   <figure><img src="/files/DpeiHeg8dHNvUAwb0L6m" alt=""><figcaption></figcaption></figure>
2. **View Available Markets:** On the left side of the dashboard, check the "Assets To Supply" list to see which markets are available.
3. **Select the Asset:** Choose the asset you wish to supply as collateral, and click “Supply”.
4. **Specify the Amount:** You can enter the amount manually or use the max option to select the amount you wish to deposit.

   <figure><img src="/files/5lKWuKYGUyj9rSCzkXGh" alt=""><figcaption></figcaption></figure>
5. **Review Terms:** Before finalizing, review the Annual Percentage Yield (APY), Gas Fee, and Health Factor associated with the asset.
6. **Confirm Transaction:** Click the "Supply Asset" button to complete the supply process.

   <figure><img src="/files/uTZBy5YZUWQbURvZ6Gtu" alt=""><figcaption></figcaption></figure>

#### **Supply Caps**

Supply caps define the maximum amount of an asset which can be supplied to the protocol. Supply caps can be used to limit the protocol’s exposure to riskier assets and protect against infinite minting exploits. A supply cap is an optional parameter, and the value will depend on on-chain liquidity of the asset and total volume of collateral assets in the pool.


# Borrow

By depositing supported tokens as collateral at Yei Finance, you gain the ability to borrow various assets. The terms of borrowing, such as the Loan-to-Value (LTV) ratio, conform to predefined risk parameters, with interest accruing according to these terms.

### **How to Borrow?**

#### **Preparing to Borrow**

To enable borrowing, first deposit assets as collateral. The maximum amount you can borrow depends on:

* The value of your deposited assets.
* The type of assets you have deposited.
* The liquidity available in the assets you wish to borrow.

#### **Borrowing Procedure**

To borrow assets from Yei Finance, follow these straightforward steps:

1. **Access the Dashboard:** Begin by navigating to the Yei Finance dashboard as you would for other transactions.
2. **Select the Asset:** Go to the “Assets to Borrow” section, find the asset you wish to borrow, and click the “Borrow” button.
3. **Specify the Amount:** Enter the desired borrowing amount manually or use the 'max' option to select the highest permissible amount based on your collateral.

   <figure><img src="/files/mkfFSoe73eAf87h6qrpl" alt=""><figcaption></figcaption></figure>
4. **Review Terms:** Carefully review all associated terms, including any warnings, the Gas Fee, and your Health Factor.
5. **Acknowledge Risks:** If presented, tick the box to acknowledge the risks involved in borrowing.

   <figure><img src="/files/YPxtcYeCZV4BpS7WsJX9" alt=""><figcaption></figcaption></figure>
6. **Confirm Transaction:** Click the "Borrow Asset" button to finalize the borrowing process.

   <figure><img src="/files/NwiNn2VwHw52WZnYJuZv" alt=""><figcaption></figcaption></figure>

#### **Potential Risks of Borrowing**

Borrowing carries inherent risks, especially if market conditions fluctuate significantly:

* **Risk of Liquidation:** If your Health Factor falls below 1, the protocol may initiate liquidation of your collateral to cover the debt, which could lead to substantial losses.

#### **Borrow Caps**

Borrow caps define the maximum amount of an asset which can be borrowed. Borrow caps can be used to prevent traditional and flash borrowing of an asset which may experience a price exploit and lead to protocol insolvency. A borrow cap is an optional parameter, and the value will depend on-chain liquidity of the asset and total volume of borrowed assets in the pool.


# Withdraw

Follow these steps to smoothly process your fund withdrawals:

1. **Access the Dashboard** as above.
2. **Select the Asset:View “Your Supplies”, and choose the asset you wish to Withdraw,** and click “**Withdraw**”.
3. **Specify the Amount:** You can enter the amount manually or use the max option to select the amount you wish to withdraw.

   <figure><img src="/files/GlRhHTeccytegcipzrXa" alt=""><figcaption></figcaption></figure>
4. **Review Terms:** Before finalizing, review the Remaining supply, Gas Fee, and Health Factor associated with the asset.

   <figure><img src="/files/ZMX231OtuTBr2RqE6oRp" alt=""><figcaption></figcaption></figure>
5. **Confirm Transaction:** Click the "Withdraw Asset" button to complete the supply process.

   <figure><img src="/files/Ol0rOzQ4xIlVuC6xzTxJ" alt=""><figcaption></figcaption></figure>

**Note:** Be mindful that withdrawals can impact your Health Factor and might increase the risk of liquidation.

#### **Liquidity Considerations**

Ensure there is sufficient liquidity within Yei Finance that isn't currently being borrowed. If liquidity is insufficient, you may have to wait until more funds become available or until other borrowers repay their loans.

#### **Potential Risks**

In extreme market conditions, such as when the pool's utilization hits 100%, you may find yourself unable to withdraw your deposits immediately.


# Repay

Repaying your borrowed assets is crucial for maintaining a healthy financial status within Yei Finance. Here’s how to do it:

1. **Access the Dashboard:** Similar to other transactions, start by accessing your Yei Finance dashboard.
2. **Select the Asset:** Navigate to the “Your Borrows” section, select the asset you want to repay, and click “Repay.”
3. **Specify the Amount:** Enter the amount you want to repay, either by typing it manually or selecting the 'max' option to repay the total due.

   <figure><img src="/files/v32OFf0PRzJ2WdKp76PW" alt=""><figcaption></figcaption></figure>
4. **Review Terms:** Check the remaining debt, the Gas Fee, and the Health Factor before proceeding.
5. **Confirm Transaction:** Click the "Repay Asset" button to complete the repayment.

# High Efficiency Mode (E-mode)

### Overview

The High Efficiency Mode (E-mode) is designed to maximize capital efficiency by allowing users to leverage assets with correlated prices as collateral. This feature is particularly beneficial when dealing with assets like stablecoins, which maintain a consistent value relative to a specific reference, such as the USD.

### E-mode Asset Categories

Yei Finance supports two primary asset categories under E-mode:

1. **Stablecoins**: Examples include USDC and USDT, which are pegged to the USD and exhibit correlated price movements. Utilizing stablecoin E-mode, users can supply stablecoins and enjoy higher collateralization power when borrowing other stablecoins.
2. **SEI-related Assets**: This category includes assets such as WSEI and SEI. In SEI E-mode, users can supply these assets and benefit from a higher borrowing Loan-to-Value (LTV) ratio of up to 75%, thereby enhancing borrowing capacity.

### Borrowing Rules in E-mode

* **Category Restriction**: Only assets within the same category can be borrowed in E-mode. For instance, if a user supplies stablecoins in E-mode, they can only borrow other stablecoins.
* **Collateral Usage**: E-mode does not restrict the usage of other assets as collateral. Assets outside of the E-mode category can still be supplied as collateral, adhering to normal LTV and liquidation parameters.

### **How to Enter E-mode**

1. **Enable E-mode:** From the dashboard, find “Your borrows” and click “Enable E-mode.”

   <figure><img src="/files/eJeSHrDik0MpLoniMuNS" alt=""><figcaption></figcaption></figure>
2. **Follow Instructions:** After checking the warning and Gas Fee, click “Enable E-mode” to activate enhanced borrowing capabilities.

   <figure><img src="/files/tqVUX33wjoHWGQmfWvFZ" alt=""><figcaption></figcaption></figure>

### **How to Exit E-mode**

1. **Disable E-mode:** Select “stablecoins” icon under “Your Borrows” and click “Disable E-mode”.

   <figure><img src="/files/jgEnF4AFJfTESnU4rVwA" alt=""><figcaption></figcaption></figure>
2. After checking the Health factor, Maximum loan to value and Gas Fee, click “Disable E-mode” to deactivate E-mode.

### How to Switch Asset Category Under E-mode

1. **Switch E-mode Category**: Select the E-mode icon and choose "Switch E-mode Category" to switch between SEI-related E-mode and Stablecoin E-mode.

<figure><img src="/files/eIyogP6Xu28nRYAG0R3d" alt=""><figcaption></figcaption></figure>

2. **Confirm Assets Under E-mode**: Before switching to another asset category, ensure that you have repaid any outstanding debt under the current asset category.

<figure><img src="/files/enM7Gizbbpy450ivwsMG" alt=""><figcaption></figcaption></figure>


# Isolation Mode

Isolation mode allows for the creation of isolated pools, each with distinct asset collections that have tailored risk management settings. This structure not only facilitates targeted risk management but also confines potential disruptions to individual markets, protecting the overall protocol's liquidity.

#### **Entering Isolation Mode**

Isolation mode is accessible for specific assets approved by Yei Governance. Here’s how to enter:

1. **Select an Isolated Asset:** From the dashboard, choose an isolated asset to supply.

   <figure><img src="/files/PG9jlNNHjTiOTcoWrkrh" alt=""><figcaption></figcaption></figure>
2. **Notification:** A prompt will inform you that you are entering isolation mode.

   <figure><img src="/files/SkLWcEhFZEJUroTPiLUB" alt=""><figcaption></figcaption></figure>
3. **Supply Assets:** Supply the chosen isolated asset into the pool.
4. **Borrow Assets:** Once in isolation mode, borrow stablecoins designated for this mode by Yei Governance.

#### **Exiting Isolation Mode**

To exit isolation mode:

1. **Disable Isolated Asset:** In the “Your supplies” section, toggle the slider to disable the asset.
2. **Confirm:** Click “Disable Asset as collateral” and confirm the Gas Fee to exit isolation mode.

#### **Impact on Borrowing Power**

In isolation mode, your borrowing options are limited to stablecoins. This mode imposes a specific debt ceiling per asset, which is displayed on each asset’s reserve page.


# Liquidations

### **Liquidation Process**

Liquidation is a critical safety mechanism within Yei Finance, triggered when the market value of collateral drops below a certain threshold. This process helps maintain the stability and security of the liquidity pool by ensuring that loans are repaid even in adverse market conditions.

#### **Liquidation Threshold**

The liquidation threshold is a key indicator that determines when a loan becomes undercollateralized. For example, if the liquidation threshold is set at 95%, any position whose value exceeds 95% of its collateral's worth is at risk of being liquidated.

#### **Understanding the Health Factor**

The Health Factor (HF) is a crucial metric used to assess the risk of liquidation:

$$
HealthFactor = \frac{CollateralValue \times LiquidationThreshold}{BorrowedValue}
$$

A Health Factor below 1 indicates a heightened risk of liquidation, prompting the protocol to potentially liquidate the collateral to cover the outstanding debt.

#### **Liquidation Scenarios**

**Scenario 1:**

Bob deposits 1000 SEI and borrows 600 SEI worth of USDC. If his Health Factor drops below 1, his position becomes eligible for liquidation. A liquidator can repay 50% of the borrowed amount (300 SEI worth of USDC) and claim a 5% bonus, resulting in the acquisition of 315 SEI.

**Scenario 2:**

In another scenario, Bob deposits 500 SEI and an equivalent value of iSEI, then borrows 500 SEI worth of USDC. If his position becomes eligible for liquidation, a liquidator repays 250 SEI worth of USDC and opts to claim iSEI due to its higher liquidation bonus of 15%, receiving a total of 287.5 SEI worth of iSEI.

#### **Role of Liquidation Bots**

Liquidation within Yei Finance is permissionless, allowing anyone to participate as a liquidator if the process is deemed profitable. This openness ensures that the protocol remains robust and reactive to market dynamics. Initially, the Yei team will deploy dedicated liquidation bots to facilitate efficient protocol operations.

#### **Liquidation Penalty**

The liquidation penalty, which varies by collateral type, encourages liquidators to help maintain the protocol's financial stability.

| Assets | Liquidation Penalty |
| ------ | ------------------- |
| SEI    | 8.5%                |
| USDT   | 6.5%                |
| iSEI   | 6.5%                |
| WETH   | 8.5%                |
| WBTC   | 8.5%                |

# Yei Points

How do Yei points work on Yei Finance?

#### Why Join Yei’s Points Program?

Earn points for your lending and borrowing activities in addition to Yei’s $SEI incentives. Go to your [dashboard](https://app.yei.finance/points/) to keep track of your points and progress.

#### How to Earn Points?

1. **Lending**:
   * Add supported assets on Yei.
   * Earn **1 point per dollar** worth of assets lent per day.
2. **Borrowing**:
   * Borrow supported assets on Yei.
   * Earn **4 points per dollar** worth of assets borrowed per day.
3. **Referrals**:
   * Share your referral link with friends.
   * Earn extra points by referring users:
     * **Direct Referral (A):** Earn 10% of the points earned by user A.
     * **Second-Level Referral (B):** Earn 5% of the points earned by user B, who is referred by user A.
     * **Third-Level Referral (C):** Earn 2.5% of the points earned by user C, who is referred by user B.
     * **Fourth-Level Referral (D):** Earn 1.25% of the points earned by user D, who is referred by user C.

#### Example Scenarios

* **Lending**: If Yeida deposits 100 $SEI on Yei for a day, with $SEI priced at $0.80, he earns 80 points (100 \* 0.8 \* 1 = 80). If Yeida deposits and holds 50 $SEI for 2 days, he also earns 80 points (50 \* 0.8 \* 2 = 80). Points accumulate based on the amount and duration of deposits.
* **Borrowing**: If Yeida borrows $100 worth of assets from Yei, such as 100 $USDC for one day, he earns 400 points (100 \* 4 = 400). If Yeida borrows and holds $50 $USDC for two days, he earns 400 points (50 \* 4 \* 2 = 400). Points accumulate based on the amount and duration of borrowed assets.
* **Referrals:** If Yeida refers a friend (A) who earns 1000 points, Yeida will earn 100 points (10% of 1000 points). If A refers another user (B) who earns 500 points, Yeida will earn an additional 25 points (5% of 500 points). If B refers two users (C1 and C2), and C1 earns 400 points while C2 earns 300 points, Yeida will earn 10 points (2.5% of 400 points) from C1 and 7.5 points (2.5% of 300 points) from C2. Points can be earned from referrals down to four levels deep!


# Fees Structure

Fees are essential to maintain and secure the protocol:

* ~~Borrowing Fee: 0.2%, applied to each loan.~~ *(Temporarily waived. May be introduced in future updates.)*
* Interest Rate Spread: 20% of the borrow rate, serving as revenue for the protocol.
* Liquidation Fee: 20% of the liquidation penalty, rewarding liquidators for maintaining protocol security.
* Flash Loan Fee: 0.1%, fostering the protocol’s growth and ensuring operational stability.

*For the latest fees, please refer to our Asset Info page.*


# Oracles and Data Feeds

### **Overview**

Yei Finance employs a comprehensive price module system that integrates multiple oracle providers. API3 serves as the primary oracle, while Pyth and Redstone act as backup solutions. Oracles are fundamental to decentralized finance, supplying critical real-world data like asset market prices to the blockchain. Accurate and reliable data feeds are essential for fair collateral valuation, effective loan management, and timely liquidations.

### **Multi-Oracle Strategy**

To minimize the risk of price manipulation in lending protocols, we implement a multi-oracle integration strategy. By leveraging multiple oracle sources, we ensure the continuity and reliability of price feeds while effectively preventing anomalies.

We choose API3 as our primary oracle for providing the main data source, while additional oracles offer supplementary validation.

***

### **Oracle Providers**

#### **API3**

API3 is a top-tier oracle service offering decentralized APIs (dAPIs) that source data directly from providers, eliminating third-party intermediaries. This direct approach enhances the reliability and transparency of data feeds, contributing to the overall safety of the DeFi ecosystem.

#### **Pyth Network**

Pyth Network is an oracle protocol that bridges market data providers with applications across various blockchains. With contributions from over 100 first-party publishers, including major exchanges and market makers, Pyth offers reliable market data. It secures over 350 protocols across more than 55 blockchains.

#### **Redstone**

Redstone provides a modular oracle service, delivering frequent, reliable, and diverse data feeds. Yei Finance utilizes Redstone’s Classic model, which pushes data into on-chain storage via a relayer under specified conditions, such as heartbeat intervals and deviation thresholds. RedStone USDT and USDC push feeds are used as primary oracle for these assets.


# Dynamic Interest Rate Model

Yei Finance features dynamic interest rate model in its DeFi lending protocol, adjusting in response to fluctuations in asset supply and demand. This responsive mechanism maintains liquidity balance, with interest rates escalating with increased borrowing demand and diminishing as it wanes.

#### **Components of Interest Rates**

* **Minimum Rate:** The interest rate when asset utilization is at 0%.
* **Vertex Rate:** The rate at which utilization is equal to the vertex utilization, where the rate curve changes slope.
* **Vertex Utilization:** The specific utilization percentage at which the shift in rate slope occurs.
* **Maximum Rate:** The interest rate applied when asset utilization reaches 100%.

#### **Interest Rate Formula**

The interest rate calculation depends on the current asset utilization relative to the vertex point:

# Risks

At Yei Finance, while we strive to offer robust financial tools and returns, it's crucial to acknowledge and understand the inherent risks associated with using our lending protocol:

* **Market Risks:** The crypto market is volatile; significant price fluctuations can affect the value of collateral and the stability of your investments.
* **Liquidity Risks:** There might be instances when liquidity is low, and you are unable to withdraw your assets immediately, particularly when the pool's utilization is high.
* **Liquidation Risks:** If the market value of your collateral falls below the required threshold (Health Factor below 1), your assets may be liquidated to cover the loan, potentially leading to losses.
* **Smart Contract Risks:** While our platform is built on thoroughly audited smart contracts, there is always a risk of undiscovered vulnerabilities.
* **Regulatory Risks:** Changes in cryptocurrency regulations could affect the operations of DeFi platforms, including Yei Finance.

While Yei Finance strives to minimize risks, no platform is entirely risk-free. Key concerns include potential smart contract bugs and the risk of collateral liquidation. Our commitment to transparency, open-source code, and comprehensive audits are central to our risk mitigation strategy.

# Swaps

YeiSwap lets you exchange one token for another directly within the Yei ecosystem. Trades are matched based on available liquidity in the pool, enabling fast and permissionless swaps.

### Mechanism

YeiSwap is a decentralized exchange (DEX) that integrates Yei’s native interest-bearing tokens.

* Users swap tokens as usual, with no change in experience.
* Liquidity providers (LPs) earn both **trading fees** and **lending yields**, boosting capital efficiency.

***

## Token Swap

<figure><img src="/files/xEBL2w12kCcmiorjpCRD" alt="" width="563"><figcaption></figcaption></figure>

### Important Concepts

* **Price Impact**: Change in market price caused by your trade. Larger trades experience higher impact.
* **Slippage**: Difference between expected and actual price due to market changes. Set a slippage tolerance to manage this.

### How to Swap

Follow these steps to complete a swap on Yei:

* **Select Tokens:** Choose the token to swap from and to.
* **Set Slippage:** Adjust your slippage tolerance.

<figure><img src="/files/x07AXOzOtFWMHzZb4qxA" alt="" width="257"><figcaption></figcaption></figure>

* **Review Price Impact:** Higher impact = worse rates.
* **Approve Token:** Required only on the first swap for each token.
* **Sign and Confirm:** Approve the transaction in your wallet.

# Liquidity Provision

Liquidity provision on YeiSwap helps power the DEX by enabling token swaps and allows providers to earn yield from multiple sources. You are a liquidity provider (LP) when you deposit supported token pairs or yTokens into liquidity pools.

<figure><img src="/files/u8mY7Mw3KBLu05CR60U4" alt="" width="563"><figcaption></figcaption></figure>

### Providing Liquidity

Deposit token pairs via the **Pools** tab to power swaps and earn rewards.

<figure><img src="/files/587U7YzNydzJDjTqMe0y" alt="" width="563"><figcaption></figcaption></figure>

#### yToken Pools

You can deposit yTokens directly into YeiSwap pools. For example, if you supplied SEI on YeiLend and received aYeiSEI, you can then stake the token in the pool to earn dual rewards.

<figure><img src="/files/WkR9WHWAh1LBw7qABt8b" alt="" width="563"><figcaption></figcaption></figure>

#### Dual Yield for LPs

Liquidity providers on YeiSwap earn **dual rewards**:

* **Lending Yields**: From the interest earned on the underlying yToken.
* **Trading Fees**: From swap activity in the pool.

<figure><img src="/files/mztmwb8HY4sfZ3CcEZqo" alt="" width="272"><figcaption></figcaption></figure>

Both lending yields and trading fees are automatically accrued and claimable upon withdrawal. In addition, extra **incentives are airdropped weekly** every **Wednesday at 09:00 UTC**.

{% hint style="info" %}
Providing liquidity involves risks like impermanent loss. Understand the trade-offs before participating.

* **USDC.n**: The IBC-enabled version of USDC, issued by Circle on the Noble chain and bridged to Cosmos-based chains like Sei.
* **USDC**: Native USDC on Sei is the official version of USDC directly issued by Circle to Sei via CCTP

Both are usable today, but **USDC is becoming the new standard** across the Sei DeFi ecosystem.

## Understanding the difference

| Feature              | USDC                                         | USDC.n                       |
| -------------------- | -------------------------------------------- | ---------------------------- |
| Origin               | Native USDC on Sei                           | Bridge from Noble            |
| Bridging Method      | Circle CCTP                                  | IBC                          |
| Cross-Chain Support  | Native CCTP support (Ethereum, Solana, etc.) | Limited to Cosmos IBC chains |
| Ecosystem Preference | Preferred                                    | Deprecated                   |

***

## Why migrate to USDC?

Protocols on Sei (including Yei Finance) are adopting **USDC** as the primary stablecoin for the following reasons:

* USDC is issued directly by Circle, ensuring official backing and credibility.
* USDC supports native cross-chain transfers via Circle’s CCTP.
* It has stronger oracle, analytics, and developer tooling support.
* Integrating USDC into DeFi protocols is simpler and safer.

**USDC** will be the default stablecoin on Sei, offering better native liquidity and security. As Sei transitions to EVM-only, **USDC.n will no longer be supported.**

***

## How to migrate?

You can migrate to native USDC using the following three methods:

<details>

<summary><strong>Method 1 – YeiBridge</strong><br><sub><strong>Suitable for most users. Convenient and secure, but users should watch for bridge caps and fees.</strong></sub></summary>

{% hint style="info" %}
YeiBridge also integrates with the third-party bridge Stargate. Be sure to check caps and fees before bridging.
{% endhint %}

* **Use YeiBridge to migrate.**

  * Visit [YeiBridge](https://app.yei.finance/bridge/) to send your USDC.n to another chain (such as Avalanche, Arbitrum) as USDC.

  <figure><img src="/files/eTtaIYzgSE3l13eeGkx1" alt="" width="563"><figcaption></figcaption></figure>

  * Then bridge the USDC back to Sei as native USDC.

  <figure><img src="/files/vwlSiI6J08HdTqjPqnAH" alt="" width="563"><figcaption></figcaption></figure>

  * If you don’t see native USDC in your wallet, you can add the Sei USDC token address [here](https://app.yei.finance/reserve-overview/?underlyingAsset=0xe15fc38f6d8c56af07bbcbe3baf5708a2bf42392\&marketName=sei_mainnet_1) and click “**Add token to wallet**,” then select USDC.

    <figure><img src="/files/BX9XEFEYigacQ8v8ZEew" alt=""><figcaption></figcaption></figure>

{% hint style="warning" %}
Make sure you have enough assets (such as AVAX or ETH) on the destination chain to cover transaction fees to bridge back.&#x20;
{% endhint %}

</details>

<details>

<summary><strong>Method 2 – CCTP via Skip:Go Bridge</strong><br><sub><strong>Suitable for large transfers to avoid slippage, but requires more steps and may take longer.</strong></sub></summary>

{% hint style="info" %}
This method is better for large amounts, offering zero slippage from Sei back to Noble (as of July 24, 2025).\
It leverages CCTP but requires additional setup, such as configuring a Keplr wallet.
{% endhint %}

* **Use CCTP via Skip:Go Bridge to migrate.**
  * **Transfer USDC onto your Keplr wallet.**
    * **Option 1:** Send USDC.n from your **Sei EVM wallet** to your **Keplr wallet.**

      * Go to <https://app.sei.io/> and link your Cosmos wallet to retrieve your EVM address.

      <figure><img src="/files/6S0BPYuDooKUObxmLVAC" alt="" width="563"><figcaption></figcaption></figure>
    * **Option 2: Import the private key from your Sei EVM wallet into Keplr wallet.**
  * **Navigate to Skip:Go Bridge.**

    * Visit [Skip:Go Bridge](https://go.skip.build/), and bridge USDC.n from Sei-EVM to your desired EVM chain. Make sure the bridge cross through Noble before confirming the transaction to avoid slippage.

    <figure><img src="/files/5SL2M8DtwHmiq6JcOCvi" alt="" width="369"><figcaption></figcaption></figure>

    * Wait for the bridge to complete and confirm USDC in your wallet.
  * Bridge native USDC back.&#x20;

    * Visit [YeiBridge](https://app.yei.finance/bridge/)to bridge native USDC back to Sei.

    <figure><img src="/files/pD8RlalmdH0rvQ0oVaBy" alt="" width="524"><figcaption></figcaption></figure>

{% hint style="warning" %}
Make sure you have enough assets (such as AVAX or ETH) on the destination chain to cover transaction fees to bridge back.&#x20;
{% endhint %}

</details>

<details>

<summary><strong>Method 3 - YeiSwap</strong><br><sub><strong>Fastest method. Ideal for smaller amounts. Be aware of potential slippage.</strong></sub></summary>

{% hint style="info" %}
Make sure to have Sei token in your wallet to pay for the transaction.
{% endhint %}

* **Swap on YeiSwap.**
  * Visit [YeiSwap](https://swap.yei.finance/) to convert assets into USDC directly on Sei.

* Direct backing by Ethereum USDT.
* Native compatibility with omnichain transfers (via LayerZero).
* Stronger oracle and tooling support.
* Simpler and safer app integrations.
* Future-proof ecosystem compatibility.

**USDT0** will be the default stablecoin on Sei, offering better native liquidity and security. As Sei transitions to EVM-only, **KavaUSDT will no longer be supported.**

***

## How to migrate?

You can migrate to USDT0 using the following three methods:

#### Method 1:&#x20;

* **Swap on YeiSwap.**
  * Visit [YeiSwap](https://swap.yei.finance/) to convert KavaUSDT into USDT0.

# Flash Loans

Flash loans are innovative financial instruments tailored for developers, allowing the borrowing of assets without collateral, provided the liquidity is returned within a single blockchain transaction.

#### **How Flash Loans Work**

Flash loans necessitate a comprehensive understanding of the Ethereum Virtual Machine (EVM), programming, and smart contracts. They provide pool liquidity for a single transaction, requiring the entire borrowed amount plus an additional fee to be returned by the transaction's conclusion.

#### **To initiate a Flash Loan, follow these steps:**

1. **Build a Smart Contract:** Your contract should be capable of requesting and managing a flash loan.
2. **Execute Operations:** The contract executes the necessary operations and repays the loan with interest and fees within the same transaction.

For detailed guidance on executing flash loans, refer to our developer documentation.

#### **Execution Flow of a Flash Loan**

1. **Contract Request:** Your contract requests a flash loan from the Pool, specifying the amount and reserve.
2. **Funds Transfer:** The Pool transfers the requested funds to your contract and triggers **`executeOperation()`**.
3. **Operation Execution:** Perform your planned operations using the borrowed funds.
4. **Repay the Loan:** Approve the Pool to pull the loan amount plus fees from your contract, completing the transaction in one block.

#### **Applications of Flash Loans**

* **Arbitrage:** Exploit price differences across exchanges without upfront capital.
* **Position Liquidations:** Liquidate positions without needing to front the repayment capital.

#### **Flash Loan Fees**

Flash loan fees start at 0.1% and can be adjusted via Governance Vote. These fees contribute to the protocol's stability and are shared between liquidity providers and the treasury.
