USDC (USD Coin) is a fully-reserved stablecoin issued by Circle. It is available on both Polygon and Arbitrum, making it one of the most popular assets to bridge between the two networks.

Native USDC vs Bridged USDC

Arbitrum supports both native USDC (issued directly by Circle via CCTP) and bridged USDC.e (wrapped from other chains). When bridging from Polygon, most bridges deliver USDC or USDC.e on Arbitrum. Check the token contract on Arbiscan to confirm which version you receive.

How Much Does It Cost to Bridge USDC?

Bridging USDC from Polygon to Arbitrum costs a small amount of POL for the Polygon gas fee, typically under $0.05. Some bridge protocols also charge a fixed fee per transaction ranging from $0.01 to $0.50. Compare routes before confirming to get the best rate.

USDC Bridge Step-by-Step

Connect your wallet to the bridge, set Polygon as the source and Arbitrum as the destination, select USDC, enter the amount, approve token spend if prompted, and submit the transaction. Transfers usually complete in under two minutes.

DeFi Opportunities for USDC on Arbitrum

Arbitrum's DeFi ecosystem includes some of the highest-yield stablecoin opportunities in all of DeFi. You can supply USDC to Aave, Compound, or Radiant Capital for lending yield, deposit into stablecoin pools on Curve or Balancer, or use USDC as collateral to open leveraged positions.

Security Considerations

Use well-audited bridge protocols with a proven track record. Check that the bridge has processed substantial volume and has no recent security incidents. Never bridge more than you can afford to lose when using any new or unaudited protocol.
