What is Across Protocol?
Across Protocol is a cross-chain bridge that uses an intent-based architecture for fast, capital-efficient asset transfers. Unlike traditional bridges that lock and mint tokens, Across uses a network of relayers who front capital to users, getting repaid from liquidity pools. This design enables near-instant bridging with competitive fees.
Built by the UMA team, Across has become one of the most-used bridges for fast transfers between Ethereum and Layer 2 networks.

How Across Works
Intent System: Users express intent to bridge; relayers compete to fill orders. Fastest relayer wins the fill fee. Liquidity Pools: LPs provide single-asset liquidity that relayers draw from and repay. Optimistic Verification: Uses UMA's optimistic oracle for dispute resolution.Yield Opportunities
1. LP Provision (5-15% APY)
- Provide single-asset liquidity (ETH, USDC, etc.)
- Earn from bridge fees
- Available across multiple chains
- No impermanent loss (single asset)
2. ACX Staking
- Stake ACX for governance
- Potential fee sharing
- Protocol development participation
3. Relayer Operation
- Advanced: Run relayer infrastructure
- Earn fill fees for fronting capital
- Requires technical setup

Risk Considerations
- Bridge Risk: Cross-chain protocols have unique risks
- Relayer Dependency: Relies on active relayer network
- Liquidity Utilization: Pool usage varies
- Smart Contract Risk: Complex bridging mechanics
