Learn how Aarc processes each deposit, from the moment a user initiates it to the final on-chain result or refund.

​
1. Initiating a Deposit

A user or dApp begins by creating a transaction request on Aarc. This request includes:

  • Desired Destination: The DeFi app or contract where funds should end up (e.g., vault, lending pool)
  • Target Token/Amount: The exact token and amount expected on the destination chain

Based on this information, Aarc generates a unique, single-use deposit address for the transaction. Users simply send their funds to this address, no token approvals or bridging steps needed.

​
2. Sending Funds

Once the user transfers funds to the deposit address:

  1. Aarc’s system detects the incoming transaction on the source chain
  2. The deposit address routes the funds to router contracts for execution via relayer
  3. No separate approvals or manual bridging are required, it’s all handled automatically

If the initial bridging route encounters issues (like low liquidity), we automatically try alternative routes to ensure success.

​
3. Execution & Monitoring

Aarc aggregates routes across multiple swap, bridge, and solvers to:

  • Bridge & Swap the deposited assets to obtain the exact target token
  • Deliver the final token to the specified destination smart contract or wallet
  • Manage gas on the destination chain, eliminating the need for users to hold native gas tokens

This process typically completes in under 1 minute. During network congestion or liquidity constraints, the system will automatically retry for up to 30 minutes.

​
4. Completion or Refund

  • Successful Completion - When executed successfully, funds arrive on the destination chain/contract in the exact amount specified, and any calldata is executed. There are no partial executions or shortfalls.
  • Automatic Refund - If Aarc cannot fulfill the transaction within 30 minutes of retries, we automatically issue a refund:
    • Where: Refund type depends on the failure point. Early failures return the original asset on the source chain. Mid-process failures may refund in stablecoin or ETH on the chain where the failure occurred.
    • No Manual Intervention: Refunds process automatically without user claims
    • Fees: Already-incurred bridging or swap costs may not be reversible
