The yield agent is an autonomous AI that monitors lending vaults on Base and Arbitrum, automatically moving your USDC to the highest-yielding opportunity.

​
1. Connect & Setup

On connect, n0ir creates a deterministic smart account (ZeroDev Kernel) bound to your EOA. You sign once to approve the agent’s session key with limited permissions. Your EOA remains the root owner — you can revoke the agent or withdraw directly at any time.

​
2. Deposit

Deposit USDC on Base. The agent identifies the top net-yield vault and deposits automatically.

​
3. Continuous Monitoring

The agent scans all whitelisted vaults and tracks:
  • APY across every vault on every supported chain
  • Net gain validation over a 2-day holding period
  • Anti-oscillation checks to prevent ping-pong between vaults

​
4. Intelligent Rebalancing

The agent moves funds only when net-profitable:

Same-Chain Move

Requires ΔAPY >= 1% to trigger a rebalance. No bridge fee.

Cross-Chain Move

Requires ΔAPY >= 3% to justify the bridge cost via CCTP.
Anti-oscillation: the agent won’t revert to a previous vault unless the new target is >= 3% better.

​
5. Cross-Chain Transfers

For cross-chain moves between Base and Arbitrum, the agent uses Circle CCTP with dynamic mode selection:
ModeFeeWhen Used
Fast Transfer0.01%Breakeven < 6 hours (large APY gain)
Standard Transfer0%Breakeven >= 6 hours (saves fee)
The strategy engine automatically selects the optimal mode based on breakeven analysis.

​
6. Withdrawal

Request a withdrawal and the agent:
  1. Exits all vault positions across chains
  2. Bridges funds to your home chain (Base by default) via CCTP
  3. Transfers USDC to your EOA
