Fly

Fly is a decentralized liquidity aggregation protocol designed to make cross-chain crypto swaps faster, simpler, and more cost-effective. It lets users exchange assets between supported blockchains without arranging a bridge or finding separate decentralized exchanges. By aggregating liquidity and coordinating cross-chain transactions, Fly aims to provide competitive swap pricing across a broad range of tokens and networks. Its platform supports more than 12 chains, including Ethereum, Solana, Arbitrum, Base, Avalanche, Polygon, and Optimism, with additional networks listed as new or planned integrations.

Users connect a compatible Web3 wallet, select the source and destination tokens and chains, confirm the swap, and receive the assets in their wallet. The dApp also offers portfolio and token-favoriting features, while Fly Explorer, documentation, and a help center support users and developers. Fly Boost adds rewards through activities such as swapping or depositing into partner protocols, with Eggs, Fly Fragments, and partner rewards available through its programs.
