Bridge USDC out of Sei

Method 1: Using Stargate via Yei bridge (fastest, but subject to slippage)

The easiest way to bridge USDC out of Sei is through Yei Bridge via Stargate. However, this method is subject to slippage, so if you're transferring a large amount, consider using Method 2.

Slippage is the difference between the expected price of a trade and the actual price at execution. It occurs due to price movement or low liquidity while the transaction is pending.

1. Bridge via Yei Bridge.

   • Navigate to Yei Bridge page and connect your wallet.
   • Select Sei as the source chain and choose your destination chain.

   

   • Enter the amount of USDC to bridge and review the estimated slippage.

   

   • Confirm and approve the transaction in your wallet.

   

   • Wait for the transfer to complete and verify the funds in your destination wallet.

Method 2: Using CCTP via Skip:Go bridge

This method is better for large amounts, as it offers zero slippage (as of February 20, 2025). It leverages CCTP but requires additional setup (setting up Keplr wallet).

1. Transfer USDC onto your Keplr wallet.

   • Option 1: Send USDC from your Sei EVM wallet to your Keplr wallet.

     • Copy your Sei Cosmos address (should start with "sei...").

     

     • Go to https://app.sei.io/ to link your Cosmos wallet to retrieve your EVM address.

     

     

     
   • Option 2: Import the private key from your Sei EVM wallet into Keplr wallet.

2. Bridge via Skip:Go.

   • Visit Skip:Go Bridge, and bridge USDC from Sei-Cosmos to Noble.

   

   • Send USDC from Noble to your desired EVM chain.

     • Make sure it uses CCTP before confirming the transaction to prevent slippage.

   

   • Wait for the bridge process to complete.

   • Check your destination wallet to ensure the USDC has arrived.

Note: Do not directly send from Sei to an EVM chain, Skip:go will use the Stargate route, resulting in slippage.

Both methods have their pros and cons—Stargate is simpler but subject to slippage, while CCTP via Skip:Go Bridge is more complicated but offers no slippage (only transaction fees).

For large transfers, start with a small test transaction to ensure a smooth process. Once comfortable, gradually increase the amount. Performing multiple test transactions is recommended to understand how the bridge operates.
