Across
Fast, low-cost bridge with optimistic verification. Often the fastest way to bridge USDC between L2s.
Using USDC on Across
Across Protocol is a cross-chain bridge known for fast transfers and competitive fees. It uses an optimistic verification model with UMA's oracle system, where relayers front the funds on the destination chain and are reimbursed after verification. This means you typically receive your USDC on the destination chain within minutes, often faster than other bridges. Across supports USDC transfers between Ethereum, Base, Arbitrum, Optimism, Polygon, and other chains. When native USDC is available via CCTP, Across leverages it to ensure you receive native USDC rather than a wrapped version. Across is integrated into several wallet and aggregator interfaces.
