```typescript
import * as fs from "fs";
import { verifyCheckpoint } from "./src/explainability/checkpoint.js";

const lines = fs.readFileSync("checkpoints.jsonl", "utf8").trim().split("\n");
const checkpoints = lines.map(l => JSON.parse(l));

for (const cp of checkpoints) {
  const valid = verifyCheckpoint(cp, registryAddress, 11155111, expectedSigner);
  console.log(`${new Date(cp.timestamp * 1000).toISOString()} | ${cp.action} ${cp.pair} | valid: ${valid}`);
}
```

--------------------------------

### Register Agent with web3.py

Source: https://github.com/stephen-kimoi/ai-trading-agent-template/blob/main/SHARED_CONTRACTS.md

Registers a new agent by calling the AgentRegistry contract and parsing the resulting agentId from event logs.

```python
from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://ethereum-sepolia-rpc.publicnode.com"))
registry = w3.eth.contract(address="0x97b07dDc405B0c28B17559aFFE63BdB3632d0ca3", abi=AGENT_REGISTRY_ABI)

tx = registry.functions.register(
    agent_wallet,          # hot wallet address for signing trade intents
    "My Agent",
    "A trustless trading agent",
    ["trading", "eip712-signing"],
    "https://my-agent-metadata.json"
).build_transaction({
    "from": operator_wallet,
    "nonce": w3.eth.get_transaction_count(operator_wallet),
    "gas": 300000,
})

signed = w3.eth.account.sign_transaction(tx, private_key=operator_private_key)
tx_hash = w3.eth.send_raw_transaction(signed.rawTransaction)
receipt = w3.eth.wait_for_transaction_receipt(tx_hash)

# Parse agentId from AgentRegistered event logs
agent_id = registry.events.AgentRegistered().process_receipt(receipt)[0]["args"]["agentId"]
print("agentId:", agent_id)
```

--------------------------------

### Verify Registration Event

### Implement a custom algorithmic strategy

Source: https://github.com/stephen-kimoi/ai-trading-agent-template/blob/main/tutorial/07-reusable-template.md

Create a new class that implements the TradingStrategy interface to define custom market analysis logic.

```typescript
// src/agent/my-strategy.ts
import { MarketData, TradeDecision, TradingStrategy } from "../types/index";

export class MyStrategy implements TradingStrategy {
  async analyze(data: MarketData): Promise<TradeDecision> {
    // Your logic here — technical indicators, ML model, anything
    const action = data.price > data.vwap ? "BUY" : "SELL";

    return {
      action,
      asset: "XBT",
      pair: data.pair,
      amount: 100,
      confidence: 0.7,
      reasoning: `Price ($${data.price}) is ${action === "BUY" ? "above" : "below"} VWAP ($${data.vwap.toFixed(2)}). ${action}.`,
    };
  }
}
```

--------------------------------

### Define EIP-712 Domain for AgentRegistry

Source: https://github.com/stephen-kimoi/ai-trading-agent-template/blob/main/SHARED_CONTRACTS.md

Defines the EIP-712 domain parameters for signing checkpoints against the AgentRegistry. Used for verifying agent signatures.

### Kraken Client CLI Execution Logic

Source: https://github.com/stephen-kimoi/ai-trading-agent-template/blob/main/tutorial/03-kraken-connection.md

This TypeScript code snippet shows how the Kraken client spawns the CLI as a subprocess to execute commands. It handles authentication arguments and JSON parsing.

```typescript
private async run(subcommand: string[], isPrivate = false): Promise<unknown> {
  const args: string[] = [];
  if (isPrivate && !this.sandbox) {
    args.push("--api-key", this.apiKey, "--api-secret", this.apiSecret);
  }
  args.push(...subcommand);
  args.push("-o", "json");

  const { stdout } = await execFileAsync(KRAKEN_BIN, args, { timeout: 15000 });
  return JSON.parse(stdout.trim());
}
```

--------------------------------

### Build and Sign TradeIntent

Source: https://github.com/stephen-kimoi/ai-trading-agent-template/blob/main/tutorial/04-vault-riskrouter.md

TypeScript implementation for constructing, signing, and submitting a trade intent to the RiskRouter.

```typescript
const riskRouter = new RiskRouterClient(routerAddress, agentWallet, SEPOLIA_CHAIN_ID);

// 1. Build intent (fetches current nonce from chain)
const intent = await riskRouter.buildIntent(
  agentId,
  agentWallet.address,
  "XBTUSD",
  "BUY",
  100,   // $100 USD
  { maxSlippageBps: 50, deadlineSeconds: 300 }
);

// 2. Sign with EIP-712 (agentWallet is the hot signing key)
const signed = await riskRouter.signIntent(intent, agentWallet);

// 3. Submit to RiskRouter
const result = await riskRouter.submitIntent(signed);

if (result.approved) {
  console.log("Trade approved — intentHash:", result.intentHash);
} else {
  console.warn("Trade rejected:", result.reason);
}
```

```solidity
function register(
    address agentWallet,
    string calldata name,
    string calldata description,
    string[] calldata capabilities,
    string calldata agentURI
) external returns (uint256 agentId) {
    require(bytes(name).length > 0, "AgentRegistry: name required");
    require(agentWallet != address(0), "AgentRegistry: invalid agentWallet");

    agentId = _nextAgentId++;
    _mint(msg.sender, agentId);        // ERC-721 mint
    _setTokenURI(agentId, agentURI);

    agents[agentId] = AgentRegistration({
        operatorWallet: msg.sender,
        agentWallet: agentWallet,
        name: name,
        description: description,
        capabilities: capabilities,
        registeredAt: block.timestamp,

import { ethers } from "ethers";
import { RiskRouterClient } from "./src/onchain/riskRouter";

const provider = new ethers.JsonRpcProvider(process.env.SEPOLIA_RPC_URL);
const agentWallet = new ethers.Wallet(process.env.AGENT_WALLET_PRIVATE_KEY!, provider);
const SEPOLIA_CHAIN_ID = 11155111;

const riskRouter = new RiskRouterClient(
  process.env.RISK_ROUTER_ADDRESS!,
  agentWallet,
  SEPOLIA_CHAIN_ID
);

// Build a TradeIntent for a proposed trade
const intent = await riskRouter.buildIntent(
  14n,                    // agentId (ERC-721 token ID)
  agentWallet.address,    // agentWallet
  "XBTUSD",              // trading pair
  "BUY",                 // action
  100,                   // amount in USD
  { maxSlippageBps: 50, deadlineSeconds: 300 }  // 0.5% slippage, 5 min deadline
);

// Sign the intent with EIP-712
const signed = await riskRouter.signIntent(intent, agentWallet);
console.log(`Intent hash: ${signed.intentHash}`);

// Submit to RiskRouter for on-chain validation
const result = await riskRouter.submitIntent(signed);
if (result.approved) {
  console.log("Trade approved! Proceeding with execution...");
} else {
  console.log(`Trade rejected: ${result.reason}`);
  // e.g., "exceeds max position size" or "rate limit exceeded"
}

// Simulate without state change (dry run)
const simulation = await riskRouter.simulateIntent(intent);
// { approved: true, reason: "OK" }

// Configure risk parameters for an agent (owner only)
await riskRouter.setRiskParams(
  14n,     // agentId
  10000,   // maxPositionUsd ($10,000)
  500,     // maxDrawdownBps (5%)
  10       // maxTradesPerHour
);

// Read current risk parameters
const params = await riskRouter.getRiskParams(14n);
// { maxPositionUsd: 10000, maxDrawdownBps: 500, maxTradesPerHour: 10, active: true }
```

                registeredAt:agent[5],
                active: agent[6],
                claimed,
                balance: parseFloat(ethers.utils.formatEther(balance)).toFixed(4),
                trades: Number(trade[0] || 0),
                valScore: Number(valScore),
                repScore: Number(repScore),
            };
        })
    );
    return rows.sort((a,b) => b.valScore !== a.valScore ? b.valScore - a.valScore : b.repScore - a.repScore);
}
```

### Implement Custom Trading Strategy

Source: https://context7.com/stephen-kimoi/ai-trading-agent-template/llms.txt

Implement the TradingStrategy interface to define custom trading logic. The agent loop handles all other aspects like identity, risk, and execution.

```typescript
import { MarketData, TradeDecision, TradingStrategy } from "./src/types/index";

// Custom strategy implementation
class MyTradingStrategy implements TradingStrategy {
  async analyze(data: MarketData): Promise<TradeDecision> {
    // MarketData contains:
    // - pair: "XBTUSD"
    // - price: 66422.6 (last traded price)
    // - bid/ask: best bid/ask prices
    // - volume: 24h volume
    // - vwap: volume-weighted average price
    // - high/low: 24h high/low
    // - timestamp: Unix timestamp (ms)

    const priceChange = (data.price - data.vwap) / data.vwap;

    if (priceChange > 0.02) {
      return {
        action: "SELL",
        asset: "XBT",
        pair: data.pair,
        amount: 100, // USD
        confidence: 0.75,
        reasoning: `Price ${(priceChange * 100).toFixed(2)}% above VWAP. Taking profit.`
      };
    }

    if (priceChange < -0.02) {
      return {
        action: "BUY",
        asset: "XBT",
        pair: data.pair,
        amount: 100,
        confidence: 0.70,
        reasoning: `Price ${(Math.abs(priceChange) * 100).toFixed(2)}% below VWAP. Buying dip.`
      };
    }

    return {
      action: "HOLD",
