Native USDC

On supported chains (OP Mainnet, Base and Arbitrum), Superbridge is integrated with Circle's Cross-Chain-Transfer-Protocol (CCTP) to issue native USDC rather than bridged USDC.e.

How does native USDC issuance work?

As opposed to standard bridging with the Superbridge, where funds are routed through the rollup native smart contracts, native USDC issuance is a two step mint and burn process via the CCTP smart contracts. After initiating the burn transaction on the origin chain, users are then able to mint the corresponding amount of USDC on the destination chain.

Hyperlane relaying

Thanks to our native integration with Hyperlane, USDC bridging is a one step (one transaction) process as opposed to the standard two offered by other bridging interfaces.

The initiating transaction costs a little more gas than usual, but this payment to the Hyperlane relayers ensures they can send the necessary mint transaction on the destination chain.
