Across Protocol
The fastest, cheapest, and most secure cross-chain bridge.
Overview
Across is a cross-chain bridge that focuses on speed, low costs, and security for transferring assets between Ethereum and Layer-2 networks. It uses an intents-based architecture combined with a network of relayers and a single liquidity pool on Ethereum. This design allows for highly capital-efficient and fast bridging, as relayers front the funds on the destination chain and are repaid later from the main pool.
✨ Key Features
- Intents-based architecture
- Fast, low-cost transfers
- Single liquidity pool for high capital efficiency
- Optimistic oracle for security
- Focus on Ethereum and L2s
🎯 Key Differentiators
- Intents-based design is highly flexible and efficient
- Single liquidity pool on Ethereum minimizes capital fragmentation
- Often has the lowest fees for L2-to-L2 transfers
Unique Value: Offers a combination of speed, security, and extremely low costs for cross-chain transfers within the Ethereum ecosystem by using a novel intents-based design and concentrating liquidity.
🎯 Use Cases (3)
✅ Best For
- Providing some of the lowest fees for bridging ETH and stablecoins between major L2s.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Bridging between non-Ethereum ecosystems (e.g., to Solana or Cosmos).
🏆 Alternatives
Its architecture is often more capital-efficient than competitors that require liquidity pools on every chain, which can translate to lower fees for users.
