Across Protocol protocol
Overview
Across is an intents-based cross-chain bridge and swap layer built by Risk Labs, the same team behind the UMA optimistic oracle, which secures it. Rather than locking funds in per-chain pools, Across runs a single unified liquidity pool and a competitive relayer market: relayers front the user's funds on the destination chain almost immediately and are later reimbursed from the pool once the deposit is verified, which is why transfers typically complete in one to four minutes with a no-slippage fee model. Its developer documentation describes over $35 billion bridged in total, sub-two-second fill times and support for more than 26 blockchain networks, and markets a Swap API that teams can integrate in under an hour plus AI-agent tooling for cross-chain execution. The design leans on UMA's optimistic oracle to validate relayer repayment claims instead of a bespoke validator set. Across launched as a cross-chain bridge for Ethereum L2s and rollups, secured by UMA's optimistic oracle, and later broadened into general intents-based cross-chain swaps and a builder-facing Swap API covering 26 or more chains.
