Lidogent

Yield-bearing operating budget for AI agents, powered by Lido stETH.
Humans deposit, principal stays locked, agents spend only from yield.

What is Lidogent?

AI agents need operating budgets to pay for API calls, compute, and services. But giving an agent direct access to funds is risky — one bug or exploit and the treasury is drained.

Lidogent solves this by using Lido stETH staking yield as the agent's budget source. Humans deposit ETH, which gets staked via Lido and wrapped to wstETH. The principal is structurally locked in the smart contract — no function exists for the agent to access it. Only the yield (staking rewards, ~2.4% APR) flows into the agent's spendable balance.

All spending is enforced onchain: recipient whitelists, per-transaction caps, cycle rate limits, and per-agent budgets.

Solution

Screenshots

Stake ETH via Lido

Deposit ETH to receive stETH through Lido's staking contract. Real-time ETH price from Chainlink, balance from wallet, and exchange rate displayed. One-click staking with transaction confirmation popup.

Wrap stETH & Lock in Treasury

Wrap stETH to wstETH and lock as principal in AgentTreasury. 4-step stepper popup guides the process: approve stETH, wrap via Lido, approve wstETH, lock in treasury. All enforced onchain.

AI Chat — Pay Per Request

Chat with AI models (Claude, ChatGPT, Gemini, Perplexity) powered by OpenRouter. Each request is paid from the agent's wstETH yield balance via x402. Select which agent pays from the dropdown.

Treasury Dashboard Configuration

Configure agent permissions, hierarchy, budget cycles, and spending controls. All settings read from and write to the deployed AgentTreasury contract on Ethereum Mainnet.

Activity Feed

Track all AI chat requests and agent spending in real-time. Shows model used, message preview, cost in wstETH, and timestamp. Data persisted to localStorage.

Agent CLI — Yield-Verified AI Spend

Interactive CLI agent reads treasury state from smart contract, verifies yield onchain before each AI request, and shows payment receipt. Principal Touched: NEVER.

  → Principal never touched

Lido Finance Architecture Integration

The Lidogent protocol integrates directly with Lido Finance contracts on Ethereum Mainnet. Here are the core files composing this integration:

User Flow

stateDiagram-v2
    [*] --> Stake: Deposit ETH
    Stake --> stETH: Lido submit()
    stETH --> wstETH: wrap()
    wstETH --> Treasury: depositWstETH()
    Treasury --> Yield: stEthPerToken increases
    Yield --> Spend: agent spend()
    Spend --> [*]: AI services paid

Testing

All tests run against real Lido contracts on Ethereum Mainnet via fork testing. No mocks.

cd contracts
forge test --fork-url https://eth.drpc.org -v

30/30 tests passing covering:

• Deposits (ETH, stETH, wstETH)
• Yield accrual and spending
• Whitelist, per-tx cap, cycle rate limit enforcement
• Sub-agent budget caps and pause/resume
• Owner-only access control
• Principal withdrawal protection

Agent CLI Demo

Two CLI scripts demonstrate the agent paying for AI services from yield without touching principal.

agent-demo.ts — Interactive AI Chat (yield-verified)

Agent reads yield onchain (free, no gas), verifies budget, then serves AI requests.

cd frontend
set -a && source .env.local && set +a

# Interactive mode — chat with AI, check status, view ledger
npx tsx scripts/agent-demo.ts

# Single chat
npx tsx scripts/agent-demo.ts --chat "What is Lido stETH?"

# Treasury status only
npx tsx scripts/agent-demo.ts --status

Commands in interactive mode:

• /status — Read treasury state from smart contract
• /ledger — View spending ledger
• /quit — Exit with session summary

agent-spend.ts — Real Onchain Spend

Agent calls spend() on AgentTreasury contract — real transaction on Etherscan.

cd frontend
set -a && source .env.local && set +a

# Default amount (0.0000000001 wstETH)
npx tsx scripts/agent-spend.ts

# Custom amount
npx tsx scripts/agent-spend.ts 0.0000000002

Requires: Agent wallet funded with ETH for gas (~0.005 ETH).

Demo Flow

1. agent-demo.ts --status     → Show principal locked, yield available
2. agent-demo.ts              → Chat with AI, each request yield-verified
3. agent-spend.ts             → Real onchain spend() → Etherscan tx
4. agent-demo.ts --status     → Show totalSpentWstETH increased, principal unchanged
