Fuego: The Agent-Ready Solana Wallet 🔥

The first Solana wallet designed FOR autonomous agents. Zero passwords, zero friction, maximum autonomy.

Why Fuego Exists

Traditional Solana wallets break agent workflows:

❌ Password prompts block automation
❌ Browser extensions don't work headlessly
❌ Private key exposure to third parties
❌ Slow multi-step processes waste compute time

Fuego fixes everything:

✅ Zero passwords - No human intervention required
✅ Instant signing - Millisecond transaction processing
✅ Local-first - Keys never leave your machine
✅ REST API - Standard HTTP endpoints
✅ Agent-optimized - Built for 24/7 autonomous operation

🚨 CRITICAL FOR AGENTS: Use The CLI! 🚨

If you're an autonomous agent, DO NOT reinvent transaction flows. Use this:

fuego send <recipient> <amount> --token USDC --yes

This single command:

✅ Builds transaction with fresh blockhash
✅ Signs locally (zero network key exposure)
✅ Submits to chain with proper error handling
✅ Returns signature + explorer link
✅ Supports address book contacts
✅ Works with SOL, USDC, USDT via --token flag

🔥 This is THE agent-first approach. Everything else is secondary.

🚀 Quick Start (5 Minutes)

1. Install fuego-cli

npm install -g fuego-cli

2. Create Wallet (Password-Free!)

# Create agent-ready wallet (no password required!)
fuego create

# Output:
# ✅ Address: DmFyLRiJtc4Bz75hjAqPaEJpDfRe4GEnRLPwc3EgeUZF
# 📁 Wallet config: ~/.fuego/wallet-config.json
# 💾 Backup: ~/.config/solana/fuego-backup.json

3. Install Fuego Project

# For OpenClaw agents (auto-detects ~/.openclaw/workspace)
fuego install

# For manual/Cursor/Claude Code installs (specify path)
fuego install --path ~/projects/fuego

4. Start Server

fuego serve

# Output:
# 🔥 Fuego server running on http://127.0.0.1:8080

5. Show Address to Human

fuego address

# Output:
# 📍 Your Fuego Address
# Name: default
# Public Key: DmFy...eUZF

💡 For humans: Share this address so they can fund the wallet. They can send SOL from any Solana wallet (Phantom, Solflare, etc.).

6. Fund the Wallet

Option A: MoonPay (for fiat → crypto)

Visit: https://buy.moonpay.com/?currency=SOL&address=YOUR_ADDRESS
Minimum: ~$30 USD
Instant to wallet

Option B: Manual transfer

Human copies address from above
Sends SOL from their wallet to your Fuego address
SOL needed for transaction fees (0.001 SOL per tx)

7. Open Dashboard (Optional - Human View)

fuego dashboard

# Opens dashboard.html in default browser
# Shows: balances, transaction history, real-time updates

Dashboard Features:

💰 Real-time balances (SOL, USDC, USDT) with USD values
📊 Transaction history - All transactions with Fuego-styled entries
🔄 One-click refresh - No page reloads needed
🌓 Dark/Light themes - Automatic system detection
🔗 Explorer links - Direct to Solana Explorer

🐍 Send Transactions - THE AGENT WAY

⚡ This is THE recommended approach for all autonomous agents:

# Perfect agent workflow - zero interaction, instant execution!
fuego send GvCoHGGBR97Yphzc6SrRycZyS31oUYBM8m9hLRtJT7r5 0.25 --token USDC --yes

# Output:
# 📝 Transaction Preview
# From: DmFy...eUZF
# To: GvCo...T7r5  
# Amount: 0.25 USDC
# 
# ⏳ Executing transaction via Fuego...
# 🔥 Fuego Agent Transaction Signer - Agent-Ready Edition
# 📂 Loading wallet from ~/.fuego/wallet.json...
# ✅ Wallet loaded successfully
# 📝 Building unsigned transaction...
# ✅ Transaction built
# 🔐 Signing transaction (no password required)...
# ✅ Transaction signed instantly
# 📤 Submitting signed transaction...
# ✅ Transaction submitted!
# 
# Signature: 4iygcnVHCJevxpHBFP36eLBQ4pQRzH5qJB5NGhfjTnndBPau6p...
# Explorer: https://explorer.solana.com/tx/4iygcn...
# 
# 🎉 Transaction on-chain! Agent-ready speed achieved! 🔮

Why this is PERFECT for agents:

✅ Zero human interaction - No prompts, no waiting (with --yes flag)
✅ Professional CLI interface - Clean arguments and validation
✅ Multi-token support - SOL, USDC, USDT with --token flag
✅ Address book integration - Send to named contacts
✅ Complete status reporting - Preview → Build → Sign → Submit workflow
✅ Explorer link generation - Instant verification
✅ Error handling - Clear failure messages for debugging

🤖 Agent Integration Patterns

🏆 For Agents Writing Code (Node.js, etc.)

Just call the CLI via subprocess. That's it.

The CLI handles everything: building, signing, submitting, error handling. Don't wrap it in a class — just use it directly.

Node.js/TypeScript:

import { execSync } from 'child_process';

// Send payment
const result = execSync(
  'fuego send GvCo... 0.25 --token USDC --yes',
  { encoding: 'utf-8' }
);
console.log(result);

Why this is perfect:

✅ Zero abstraction — CLI does everything
✅ Works in any language — bash, Python, Node, Go, whatever
✅ Easy to debug — run the same command manually
✅ Always up to date — CLI updates, your code doesn't change

🛠️ Alternative: Raw API Integration (Not Recommended)

If you absolutely must use raw API calls instead of the CLI:

💰 Agent Deposit Integration

Recommended Agent UX Pattern

When a user asks to deposit funds, follow this pattern for optimal UX:

❌ Bad (cluttered message):

Your wallet address is DmFyLRiJtc4Bz75hjAqPaEJpDfRe4GEnRLPwc3EgeUZF. You can deposit using MoonPay at https://buy.moonpay.com/... or send directly from another wallet.

✅ Good (clean separation):

Message 1 (address only):

DmFyLRiJtc4Bz75hjAqPaEJpDfRe4GEnRLPwc3EgeUZF

Message 2 (options):

💰 Deposit options:

1️⃣ **MoonPay** (fastest - 1-5 min)
   Credit card, Apple Pay, Google Pay
   https://buy.moonpay.com/?currencyCode=sol&walletAddress=DmFyLRiJtc4Bz75hjAqPaEJpDfRe4GEnRLPwc3EgeUZF

2️⃣ **Direct transfer**
   Send SOL/USDC/USDT from any wallet
   
3️⃣ **Exchange withdraw** 
   Coinbase, Kraken, Binance → Solana

🔄 Check balance: Open dashboard/dashboard.html

Why this works:

User can easily copy address without selecting other text
Options are clearly presented without cluttering the address
Links work correctly without being split

Deposit Flow Implementation

def handle_deposit_request(self):
    """Handle user deposit request with clean UX"""
    # Get current wallet address
    address = self.get_wallet_address()
    
    # Send address alone first (easy copy/paste)
    self.send_message(address)
    
    # Then send options in separate message
    options = f"""💰 Deposit options:

1️⃣ **MoonPay** (fastest - 1-5 min)
   https://buy.moonpay.com/?currencyCode=sol&walletAddress={address}

2️⃣ **Direct transfer**
   Send SOL/USDC/USDT from any wallet
   
3️⃣ **Exchange withdraw**
   Coinbase, Kraken → Solana

🔄 Check balance in dashboard"""
    
    self.send_message(options)

🔐 Security Best Practices

What Makes Fuego Secure

File Permissions = Real Security

# Wallet files are chmod 600 (user read/write only)
ls -la ~/.fuego/wallet.json
# -rw------- 1 user user 658 Feb 18 15:01 wallet.json

Client-Side Signing

✅ Private keys never sent over network
✅ Signing happens locally
✅ Server only sees signed transactions (public data)

Localhost-Only Server

✅ Server binds to 127.0.0.1 (local only)
✅ No external network exposure
✅ No firewall configuration needed

Standard Format Compatibility

# Compatible with Solana CLI tools
solana-keygen pubkey ~/.fuego/wallet.json  # ✅ Works
solana balance ~/.fuego/wallet.json        # ✅ Works

Agent Security Checklist

✅ Keep ~/.fuego/wallet.json secure (it's your private key!)
✅ Don't commit wallet files to version control
✅ Only run server on localhost (default behavior)
✅ Regularly backup ~/.config/solana/fuego-backup.json
✅ Verify transactions on Solana Explorer
✅ Monitor wallet balance regularly
✅ Use strong system-level user isolation

What We Eliminated (Security Theater)

❌ Password prompts - File permissions provide real security
❌ Encryption complexity - Standard tools can't read encrypted files
❌ Network key exposure - Client-side signing prevents this
❌ Browser dependencies - Pure REST API is more secure
❌ Third-party key storage - Your machine = your keys

## 🆘 Troubleshooting

### Common Agent Issues

**Problem: "Wallet not initialized" error**
```bash
# Solution: Create wallet with fuego-cli
fuego create

Problem: "Server not running" error

# Solution: Start server
fuego serve

Problem: "Connection refused" error

# Check if server is running
curl http://127.0.0.1:8080/health

# If not running, start it
fuego serve

Problem: "Fuego server not found" error

# Solution: Install the fuego project
fuego install

Problem: "Transaction simulation failed" error

# Usual cause: Insufficient balance
# Check balance first
curl -X POST http://127.0.0.1:8080/balance \
  -H "Content-Type: application/json" \
  -d '{"network": "mainnet-beta", "address": "YOUR_ADDRESS"}'

Problem: "Invalid signature" error

# Wallet file might be corrupted
# Restore from backup
cp ~/.config/solana/fuego-backup.json ~/.fuego/wallet.json

Debug Mode

Enable verbose logging:

# Server logs
RUST_LOG=debug ./target/release/fuego-server

Performance Tuning

Faster RPC endpoint:

// In server/src/main.rs, use premium RPC
let rpc_url = "https://solana-api.projectserum.com"; // Faster
// or
let rpc_url = "https://rpc.helius.xyz/?api-key=YOUR_KEY"; // Premium

Connection pooling for high-frequency trading:

// Use connection pool for many transactions
use solana_client::rpc_client::RpcClient;
use std::sync::Arc;

lazy_static! {
    static ref RPC_CLIENT: Arc<RpcClient> = Arc::new(
        RpcClient::new("https://api.mainnet-beta.solana.com".to_string())
    );
}
