How-to: Bridge USDC

Move USDC from one blockchain to another using CCTP.

Bridge USDC across blockchains using CCTP. Circle handles attestation and minting on the destination chain. You don’t need a funded wallet or gas on the destination.

Prerequisites

Before you begin, ensure you have:

• Installed Node.js v20.18.2 or later.

• Installed Circle CLI:

  npm install -g @circle-fin/cli
  

• Completed the Agent Wallets quickstart (authenticates and funds your wallet).

Steps

Follow these steps to bridge USDC to another blockchain.

1. Check the fee

   Get the estimated fee before bridging:

   circle bridge get-fee ARB --chain BASE
   
2. Bridge USDC

   Run circle bridge transfer with the destination chain, amount, and your wallet details:

   circle bridge transfer ARB --amount 10.0 --address 0xYourWalletAddress --chain BASE
   

   USDC is burned on the source chain and minted on the destination. The command returns once the bridge is complete:

   {
     "data": {
       "message": "Bridge complete: 10.0 USDC from BASE to ARB",
       "burnTxHash": "0xabc...",
       "forwardTxHash": "0xdef...",
       "fromChain": "BASE",
       "toChain": "ARB"
     }
   }
   

   If the bridge is still processing, you can check its status:

   circle bridge status 0xabc... --chain BASE
   

See the CLI command reference for full syntax and options, including specifying a different recipient address on the destination chain.
