Across Protocol

The Bridge Ethereum Deserves! Across is a cross-chain token bridge that is secured by UMA's optimistic oracle. It is optimized for capital efficiency with a single liquidity pool, a competitive relayer landscape, and a no-slippage fee model. Across is able to process cross-chain transfers quickly because its oracle verifies transfers optimistically. However, the protocol never sacrifices speed for security. Unlike other bridge designs, Across bridge LPs or users never take on protocol or finality risk, ensuring a safe bridging experience for end users.
