Across is a cross-chain bridge powered by intents that enables you to swap across different networks with Uniswap.
Whenever you submit a swap between networks, the swap is completed by Across in order to bridge your tokens to the correct network.
Your swap order is broadcasted to a decentralized network of fillers who quickly fulfill it on the destination network. Fillers are repaid once Across Protocol verifies fillers have fulfilled the order.
The swap quote shown to you includes a fee paid directly to relayers and liquidity providers that power Across. Neither the Across protocol nor Uniswap receive any of these fees.
