This speed is achieved through Across's unique intent-based architecture, where relayers compete to fill orders on the destination chain before settlement occurs on-chain.

Across uses an intent-based design for cross-chain transfers. When you initiate a transfer, you express an "intent" to move tokens from chain A to chain B. Independent relayers then compete to fill your order on the destination chain as quickly as possible. This means you receive your tokens almost instantly — often in just 1-2 seconds. Settlement and verification happen on-chain afterward, ensuring full security without sacrificing speed. This design eliminates the traditional bridge waiting period while maintaining on-chain security guarantees.

Yes. Across offers a liquidity pool where you can deposit assets and earn yield from bridging fees. Liquidity providers earn a share of the fees generated by bridge transfers. The pool is designed to be capital-efficient, so providers can earn competitive returns. Visit the Pool section of the Across application to get started with providing liquidity.
