Chia WalletConnect Skill

Verify Chia wallet ownership via Telegram using WalletConnect integration with Sage Wallet.

What It Does

This skill provides a Telegram Mini App (Web App) that enables users to: Connect their Sage Wallet via WalletConnect v2 Sign a challenge message cryptographically Verify wallet ownership via MintGarden's signature verification API Return verification status to your Telegram bot Use Cases: NFT-gated Telegram groups Airdrop eligibility verification Web3-style authentication DAO voting authentication Proof of token holdings

Architecture

/verify command → Web App button → WalletConnect → Sage signs → Verification The user never leaves Telegram. The entire flow happens in-app via the Telegram Web App API.

Installation

# Install via ClawdHub clawdhub install chia-walletconnect # Install dependencies cd skills/chia-walletconnect npm install # Make CLI executable chmod +x cli.js

Step 1: Deploy Web App

Deploy the webapp/ folder to a public HTTPS URL: Vercel (Recommended): cd skills/chia-walletconnect/webapp vercel # Copy the URL (e.g., https://chia-verify.vercel.app) Netlify: cd skills/chia-walletconnect/webapp netlify deploy --prod Your Server: # Start Express server npm start # Expose via ngrok or reverse proxy

Step 2: Register with BotFather

Message @BotFather Send /newapp or /editapp Select your bot Web App URL: Enter deployed URL Short Name: verify

Step 3: Add to Bot

Using Clawdbot Message Tool // Send /verify command handler message({ action: 'send', target: chatId, message: 'Click below to verify your Chia wallet:', buttons: [[{ text: '🌱 Verify Wallet', web_app: { url: 'https://your-app.vercel.app' } }]] }); Handling Verification Response // In your bot's web_app_data handler bot.on('web_app_data', async (msg) => { const data = JSON.parse(msg.web_app_data.data); const { address, message, signature, publicKey, userId } = data; // Verify signature const { verifySignature } = require('./skills/chia-walletconnect/lib/verify'); const result = await verifySignature(address, message, signature, publicKey); if (result.verified) { // Wallet verified! Grant access, record verification, etc. message({ action: 'send', target: msg.chat.id, message: `✅ Wallet verified!\n\nAddress: ${address}` }); // Store verification // await db.saveVerification(userId, address); } else { message({ action: 'send', target: msg.chat.id, message: `❌ Verification failed: ${result.error}` }); } });

CLI Usage

The skill includes a CLI for testing: # Generate challenge message node cli.js challenge xch1abc... telegram_user_123 # Verify signature manually node cli.js verify xch1abc... "message" "signature" "pubkey" # Validate address format node cli.js validate xch1abc... # Start development server node cli.js server

MintGarden Signature Verification

Endpoint: POST https://api.mintgarden.io/address/verify_signature { "address": "xch1abc...", "message": "Verify ownership of Chia wallet:...", "signature": "hex_signature", "pubkey": "hex_public_key" } Response: { "verified": true }

CHIP-0002 Methods (WalletConnect)

MethodPurposechip0002_getPublicKeysFetch public keys from walletchip0002_signMessageRequest message signaturechia_getCurrentAddressGet current receive address

Verification Flow

1. User sends /verify to bot 2. Bot responds with Web App button 3. User taps button → Mini App opens in Telegram 4. Mini App initializes WalletConnect 5. User connects Sage Wallet 6. Challenge message generated (includes nonce + timestamp) 7. User signs message in Sage Wallet 8. Signature sent back to bot via Telegram.WebApp.sendData() 9. Bot verifies signature with MintGarden API 10. Bot confirms verification success/failure Time: ~5-10 seconds for full flow (user-dependent)

Environment Variables

Create .env in skill folder: PORT=3000 WALLETCONNECT_PROJECT_ID=your-project-id MINTGARDEN_API_URL=https://api.mintgarden.io

Get WalletConnect Project ID

Visit WalletConnect Cloud Create a new project Copy your Project ID Update in webapp/app.js Default Project ID: The skill includes 6d377259062295c0f6312b4f3e7a5d9b (Dracattus reference). For production, use your own.

What's Protected

✅ Challenge nonces prevent replay attacks ✅ Timestamps expire after 5 minutes ✅ MintGarden cryptographic verification ✅ No private keys ever requested ✅ HTTPS enforced by Telegram

Best Practices

Store verifications securely — Use encrypted database Rate limit — Prevent spam verification attempts Link to Telegram user ID — Prevent address spoofing Implement cooldown — 1 verification per user per day Log attempts — Audit trail for security

Production Checklist

Deploy to HTTPS URL (required by Telegram) Use your own WalletConnect Project ID Enable CORS only for your domain Add rate limiting on webhook endpoints Store verifications in persistent database Implement retry logic for network errors Set up monitoring/alerts

Web App Doesn't Load

Verify HTTPS deployment (Telegram requires SSL) Check URL is publicly accessible Test URL directly in browser Review browser console for errors

WalletConnect Connection Fails

Ensure Sage Wallet is latest version Try manual URI paste instead of QR Check WalletConnect Project ID is valid Verify Sage supports WalletConnect v2

Signature Verification Fails

Ensure message format matches exactly Confirm public key corresponds to address Check MintGarden API is operational Verify signature encoding (hex)

"No Public Key" Error

Some wallets don't expose pubkey via WalletConnect Public key is optional for verification Signature verification works without it

Simple Verification Bot

// Clawdbot skill handler const { verifySignature } = require('./lib/verify'); // /verify command if (message.text === '/verify') { await message({ action: 'send', target: message.chat.id, message: 'Verify your Chia wallet:', buttons: [[{ text: '🌱 Connect Wallet', web_app: { url: process.env.WEB_APP_URL } }]] }); } // Handle web app data bot.on('web_app_data', async (msg) => { const { address, message: challengeMsg, signature, publicKey } = JSON.parse(msg.web_app_data.data); const result = await verifySignature(address, challengeMsg, signature, publicKey); if (result.verified) { // Grant access await grantAccess(msg.from.id, address); await message({ action: 'send', target: msg.chat.id, message: `✅ Verified! Welcome, ${address.substring(0, 12)}...` }); } else { await message({ action: 'send', target: msg.chat.id, message: `❌ Verification failed` }); } });

NFT Gating

// Check if user owns specific NFT collection const { verifySignature } = require('./skills/chia-walletconnect/lib/verify'); const mintGarden = require('./skills/mintgarden'); // Assume mintgarden skill exists bot.on('web_app_data', async (msg) => { const { address, message, signature, publicKey } = JSON.parse(msg.web_app_data.data); // Verify signature first const verifyResult = await verifySignature(address, message, signature, publicKey); if (!verifyResult.verified) { return bot.sendMessage(msg.chat.id, '❌ Invalid signature'); } // Check NFT ownership const nfts = await mintGarden.getNFTsByAddress(address); const hasRequiredNFT = nfts.some(nft => nft.collection_id === 'col1required...' ); if (hasRequiredNFT) { // Grant access to private group await inviteToGroup(msg.from.id); bot.sendMessage(msg.chat.id, '✅ Access granted! Check your invites.'); } else { bot.sendMessage(msg.chat.id, '❌ You need a Wojak NFT to join!'); } });
