The Across Bridge is Open
As of today it is possible to bridge USDC, ETH, and UMA from Arbitrum back to L1 Ethereum. The bridging function works by offering incentives for relayers to offer short-term loans to users on L1, which are repaid after two hours from a liquidity pool on L1. This pool is refilled when the funds arrive from L2 transactions. These transactions are insured by UMA’s Optimistic Oracle.
