Across

What is Across?

Across is an interoperability protocol powered by intents, enabling fast and low-cost value transfer across chains without compromising security. It's the only cross-chain intents protocol currently in production.

Overview

Across revolutionizes blockchain interoperability by using an intents-based architecture. This approach solves the challenges faced by traditional message-passing protocols, offering a more efficient and user-friendly solution for cross-chain interactions.

Key Features

  • Intents-based Architecture: Users specify outcomes rather than execution paths.
  • Fast Transactions: Enables quick asset transfers and cross-chain actions.
  • Low Cost: Offers competitive fees for cross-chain operations.
  • Secure Settlement: Utilizes a robust verification process for transaction settlement.

How It Works

Three-Layer System

  1. Request for Quote Mechanism: Users express desired outcomes without specifying technical steps.
  2. Network of Competitive Relayers: Decentralized network competing to fulfill orders.
  3. Settlement Layer: Escrows funds, performs verification, and repays relayers.

Intents vs. Message-Passing

  • Traditional Approach: Message-passing between chains, facing speed, cost, and security challenges.
  • Across Solution: Intents-based architecture with relayers for instant fulfillment and secure settlement.
