AgentVault

Policy-bound treasuries for autonomous agents on BOT Chain.

AgentVault gives AI agents a controlled treasury they can use without taking full custody of user funds. Owners define policies such as allowed actions, daily spend limits, agent roles, and emergency pause. A hosted worker signs as the approved agent, executes through the deployed vault contract, and exposes every transaction through the app and BOT Chain explorer.

What It Does

• Connects BO Wallet or any injected EVM wallet.
• Switches to BOT Chain testnet.
• Lets owners configure agent roles, allowed actions, daily limits, and emergency pause.
• Supports single proposal signing and one-shot policy bundle signing.
• Shows live hosted-agent activity after the browser wallet is disconnected.
• Displays latest tx hash, block number, vault address, agent wallet, and explorer link.
• Indexes recent AgentExecution logs and exposes a public vault activity view.
• Monitors the hosted agent wallet gas balance and execution threshold.
• Scores agent reliability using heartbeat, gas, bytecode, and execution history.
• Includes Trader, Bridge Guardian, Rewards Operator, and DAO Ops policy templates.
• Deploys new vaults from the browser, with verified BDEX V2 target and selector policy for Trader vaults.
• Delivers confirmed-transaction alerts through browser notifications, Telegram, email, or webhooks.
• Creates shareable vault and referral links.
• Exports an audit log covering approvals, policies, manual wallet txs, and autonomous agent txs.

Smart Contract

The vault contract is in contracts/AgentVault.sol.

It enforces:

• owner-only configuration
• allowed agent addresses
• allowed action IDs
• daily spend limits
• event receipts for agent execution
• protocol target and function-selector allowlists
• reentrancy protection and owner withdrawals
• BDEX V2 calls from newly deployed, funded vaults

Current BOT testnet deployment:

Vault: 0xacACe949cdf6f2202F2c510d5D0674af97C11b87
Agent: 0xe5ABF60A6855048fEd12938aA6C699c86C09b915

Local Setup

npm install
npm run dev

Use .env.example for local environment values.

Guided Vault Setup

This creates fresh testnet-only deployer and agent wallets, prints the public addresses to fund, deploys the vault when both have BOT, and saves the vault address locally.

npm run setup:agentvault

Never commit .env or paste private keys into chat.

Hosted Agent

Run locally:

npm run agent:worker

Production worker:

https://agent-vault-1.onrender.com/status

The worker submits a new agent execution roughly every 60 seconds, depending on RPC and hosting latency. The hosted demo remains in proof mode. Newly deployed vaults can use bdex-v2 mode after the owner configures the verified router policy and funds the vault with test BOT.

Worker API:

GET /status                 latest heartbeat and transaction
GET /api/activity           indexed AgentExecution events
GET /api/vault              hosted vault state and agent score
GET /api/vault?address=...  public state for a shared AgentVault
GET /health                 service and gas health
