Aarc’s Relayers form the foundation of our one-click deposit infrastructure. They manage final execution across multiple blockchains, ensuring that deposits either deliver the exact intended assets.

​
Core Functions

​
On-chain Execution

When users send funds to a unique deposit address, the Relayers receive instructions from Aarc’s Coprocessor (off-chain logic) to perform these actions:

  • Token Swaps via integrated DEX routes
  • Bridging through cross-chain protocols
  • Smart Contract Interactions on the destination chain

The Relayers ensure all transactions strictly follow the user’s deposit intent, without partial fills or unexpected changes.

​
Dynamic Gas Management

If a transaction fails (due to network congestion or gas price spikes), Relayers automatically retry with updated gas fees or other parameters to complete the existing call data. They do not fetch new quotes or change the outcome; that’s handled by Aarc’s Coprocessor when a deposit needs a different route.

  • Retries happen at set intervals to maximize success during temporary network issues.
  • Refund Fallback: If completion isn’t possible within 30 minutes, users receive an immediate refund, eliminating stuck funds and manual recovery.

​
Controlled Operations

Currently, Aarc maintains a centralized relayer infrastructure to ensure consistent execution and security. This provides:

  • High Reliability: Aarc oversees relayer performance, upgrades, and monitoring.
  • Tight Security Controls: Only trusted entities can operate relayers, minimizing risks from malicious actors.
  • Future Roadmap: Plans to decentralize relayer operations while maintaining security through staking, slashing, and other incentive mechanisms.

​
Finality Assurance

Every deposit through the Aarc Relayers reaches one of two outcomes:

  • Exact Outcome: Funds arrive on the destination chain in the correct amount, completing the user’s intended action (e.g., staking, margin deposit).
  • Auto Refund: If the transaction can’t complete exactly as intended within 30 minutes, the user receives a refund in the source or a stable token on the chain of failure, without any manual claim process.
