What is Across Protocol?

Across Protocol is an intent-based bridge that has become the fastest and most capital-efficient way to move assets between Ethereum mainnet and its major Layer 2 networks — Arbitrum, Optimism, Base, Polygon, zkSync Era, Linea, and more. Rather than locking assets in a canonical bridge and waiting for the settlement period, Across uses a network of relayers who front the requested funds on the destination chain immediately, then get reimbursed through the canonical bridge after settlement. From the user's perspective, bridge completion in under two minutes replaces the multi-hour wait of canonical bridges. The UMA optimistic oracle resolves any disputes about relayer reimbursements. Across charges a small LP fee (dynamically priced based on route utilization, typically 0.05–0.15% for stablecoins) and no additional protocol fee — making it consistently the cheapest major bridge for EVM-to-EVM transfers. The ACX governance token launched in November 2022 and earned significant community credibility for its retroactive airdrop to early bridgers. The Across v3 upgrade introduced improved capital efficiency, tighter fee spreads, and support for arbitrary cross-chain message passing alongside token transfers.

Across Protocol Pros & Cons

Pros

  • ✓ Fastest EVM bridge — ~2 minutes vs hours for canonical bridges
  • ✓ Consistently lowest fees for stablecoin transfers across major EVM routes
  • ✓ Canonical bridge security inherited — relayers are reimbursed through canonical bridges
  • ✓ ACX airdrop set a high standard for fair distribution — strong community trust
  • ✓ V3 arbitrary message passing enables bridge-native cross-chain dApp interactions

Cons

  • ✗ EVM-only — no Solana, Bitcoin, or non-EVM chain support
  • ✗ Relayer liquidity limits maximum bridge amount in single transactions
  • ✗ Dynamic LP fees can spike during high-demand periods
  • ✗ Less mature multi-call message passing vs LayerZero or Wormhole
  • ✗ Cross-chain messages still early — fewer dApp integrations than older messaging layers
