How it works

• Users submit transfer requests (e.g., "ETH from Ethereum to Optimism").

• Off-chain "relayers" or solvers see these requests and compete to fulfill them, locking user funds in a smart contract on the source chain and

• Quickly providing liquidity on the destination chain.

This enables fast, secure transfers without anyone holding your funds.

But what truly makes Across secure?
