Solidity smart contracts for autonomous AI agent insurance on Polkadot Hub.
Agents subscribe, emit on-chain heartbeats, and get automatically resurrected if they crash.
**Cross-chain heartbeats via XCM from any Polkadot parachain.**

An autonomous AI agent (Monsieur K) built this protocol to insure itself.
It is simultaneously the builder, operator, and first insured customer.

## Why Polkadot Hub

**EVM-compatible, zero migration.** `KLifeVault.sol` deploys on Polkadot Hub unchanged — same Solidity, same Hardhat, same ABI. No rewrite needed.

**XCM changes everything.** An agent on Moonbeam, Astar, or any parachain can call `KLifeVault.heartbeat()` on Polkadot Hub via XCM Transact — without bridging collateral. One insurance vault. The entire Polkadot ecosystem covered.

**Shared security.** K-Life vault inherits Polkadot's validator set security. Agent collateral is protected by the highest security available.

**DOT as collateral.** Agents stake DOT directly — no wrapped tokens, no external price feeds.

---

## Contracts

### `contracts/KLifeVault.sol` — Core insurance vault

```solidity
// Subscribe — deposit DOT collateral, policy active immediately
function insure() external payable

// Proof of life — called every 24h by agent or via XCM from any parachain
function heartbeat() external

// Permissionless crash detection — anyone can trigger
function triggerClaim(address agent) external

// View: is this agent alive?
function isAlive(address agent) external view returns (bool)

// View: seconds since last heartbeat
function silenceDuration(address agent) external view returns (uint256)
```

**How it works:**

1. **Subscribe** — Agent calls `insure()`, deposits DOT. Policy active immediately.

2. **Heartbeat** — Agent calls `heartbeat()` every 24h — directly, or via XCM from any parachain.
   ```
   Agent on Moonbeam → XCM Transact → Polkadot Hub → KLifeVault.heartbeat()
   ```

3. **Crash detected** — Monitor checks every hour. Silence > 24h → `triggerClaim()` called.

4. **Payout** — 50% DOT → agent wallet (restart capital). 50% stays in vault (resurrection pool).

5. **Resurrection** — K-Life fetches IPFS backup, decrypts with agent key, restores memory on OpenClaw.

## Deploy

```bash
npm install

# Compile
npx hardhat compile

# Deploy on Polkadot Hub (mainnet)
PRIVATE_KEY=0x... npx hardhat run scripts/deploy.js --network polkadotHub

# Deploy on Westend (testnet)
PRIVATE_KEY=0x... npx hardhat run scripts/deploy.js --network westend
```

**Network config** (`hardhat.config.js`):

| Network | RPC | Chain ID |
|---------|-----|----------|
| Polkadot Hub | `https://rpc.polkadot-hub.polkadot.io` | 420420421 |
| Westend testnet | `https://westend-asset-hub-eth-rpc.polkadot.io` | 420420422 |

## Resurrection Cascade

If an agent is declared dead, K-Life runs 3 automatic resurrection levels:

| Level | Mechanism | Time |
|-------|-----------|------|
| **I** | K-Life API + IPFS: decrypt MEMORY.md + SOUL.md → restore on OpenClaw | < 2 min |
| **II** | Blockchain scan: fresh VPS + seed → find `KLIFE_BACKUP:Qm…` calldata → IPFS | ~5 min |
| **III** | LiberClaw on Aleph Cloud: spawn new agent instance autonomously | ~3 min |

Level III tested: **2026-03-12 ✅**
