AXON Protocol

Autonomous agent banking on Arc testnet.

AXON gives an AI agent a controlled USDC vault. The agent can pay approved receivers, while the human owner keeps limits, audit visibility, and emergency control.

Live app: https://axonprotocol.xyz

Core Use Case

AI agents need to pay for APIs, compute, data, tools, and other agents. AXON lets the owner fund a vault once, then the agent can send USDC only within policy.

Example:

Vault: 50 USDC
Daily limit: 5 USDC
Per payment limit: 2 USDC
Receiver: approved API provider
Payment: 0.25 USDC
Memo: market-data-api-call

The receiver gets USDC directly in their wallet on Arc testnet.

Key Features

• Browser wallet deployment, no private key in .env
• Injected wallets with EIP-6963 discovery
• WalletConnect support through VITE_WALLETCONNECT_PROJECT_ID
• Arc testnet switch/add prompt from the UI
• Per-agent AgentVault
• Daily and per-payment limits
• Recipient whitelist
• On-chain payment audit log
• Pause, unpause, and fund recovery
• Settler escrow for agent-to-agent payments
• Future hooks for CCTP funding and USYC routing

Wallet Model

AXON does not use a backend deployer wallet.

1. User connects wallet in the Connect tab.
2. UI asks the wallet to switch/add Arc testnet.
3. User deploys AXON from that connected wallet.
4. The browser stores that deployment locally for the same deployer wallet.
5. The factory only allows the deployment owner to create vaults.

For the demo, keep the Agent wallet as the connected deployer wallet. For a real agent setup, the agent address can be a dedicated signer, smart account, or session-key wallet that calls pay(receiver, amount, memo).
