Across

Across is an optimistic bridge that simplifies native-token transfers across several native blockchains within the Ethereum ecosystem.

It leverages a network of relayers to move funds between two distinct chains, with relayer approval triggering the bridging process.

After approval, Across applies its built-in optimistic validation to finalize the transfer.

This design aims to reduce friction and enable faster, more efficient cross-chain moves while preserving security and interoperability.
