# Fuego SKILL

Local Solana agent wallet with local infra for transfers (SOL, USDC, USDT), Jupiter swaps, and x402 purch.

## Quick Start

### 1. Install fuego-cli
```bash
npm install -g fuego-cli
```

### 2. Create Wallet
```bash
fuego create

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

### 3. Install Fuego Project

**Prerequisites:** Rust 1.85+ and Cargo are required to build the server.

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

# For manual installs (specify path)
fuego install --path ~/projects/fuego
```

### 4. Configure Jupiter API Key (Optional - for Swaps)

If you want to do token swaps via Jupiter, you need an API key:

1. Sign up at https://portal.jup.ag
2. Create a new API key (free tier available)
3. Add to your Fuego config at `~/.fuego/config.json`:

```json
{
  "rpcUrl": "https://api.mainnet-beta.solana.com",
  "network": "mainnet-beta",
  "jupiterKey": "your-jupiter-api-key-here"
}
```

Without this key, swaps will not work. Balance checks and transfers work without it.

### 5. Start Server
```bash
fuego serve

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

### 6. Show Address to Human
```bash
fuego address

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

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

### 7. 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)

---

## Send Transactions

**Use the CLI - this is the recommended approach:**

```bash
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

**Example:**
```bash
fuego send GvCoHGGBR97Yphzc6SrRycZyS31oUYBM8m9hLRtJT7r5 0.25 --token USDC --yes
```

---

## Token Swaps via Jupiter

### Step 1: Get a Quote First
Always show the user the expected rate before executing:

```bash
fuego quote --input BONK --output USDC --amount 100000
```

Output shows:
- Input amount (with token decimals handled automatically)
- Expected output amount
- Price impact
- Route details

### Step 2: Execute the Swap
After user confirms the quote:

```bash
fuego swap --input BONK --output USDC --amount 100000 --slippage 1.0
```

**Parameters:**
- `--input` - Input token symbol (SOL, USDC, BONK, etc.) or mint address
- `--output` - Output token symbol or mint address
- `--amount` - Amount in token units (e.g., 100000 for 100000 BONK)
- `--slippage` - Slippage tolerance in percent (default: 0.5%)

The swap script automatically:
- Fetches correct token decimals from on-chain
- Uses BigInt for precision (no floating point errors)
- Throws error if decimals cannot be determined (prevents incorrect amounts)

**Prerequisites:**
- Jupiter API key must be configured in `~/.fuego/config.json`
- See Step 4 in Quick Start for setup instructions

## Agent-Ready Architecture

```
Agent/Script
       ↓ POST /build-transfer-sol
Fuego Server (localhost:8080)
  • Builds unsigned transaction with fresh blockhash
  • Returns base64-encoded transaction + memo
       ↓ Unsigned Transaction
Agent/Script
  • Loads ~/.fuego/wallet.json (simple JSON, no password!)
  • Signs transaction locally
       ↓ Signed Transaction
Fuego Server (localhost:8080)
  • POST /submit-transaction
  • Broadcasts to Solana mainnet
       ↓ On-chain
Solana Network
```

**Security Model:**
- Private keys never leave your machine (client-side signing for all transfers)
- File permissions provide real security (chmod 600)
- No network key exposure (localhost-only server)
- Standard Solana format (compatible with CLI tools)

**One Exception - x402 Payments:**
The `/x402-purch` endpoint handles the complete payment flow internally (including signing) because x402 requires server-side proof-of-payment generation. This is a deliberate security trade-off: the server temporarily accesses the private key only to sign the specific x402 payment transaction, then immediately clears it from memory. This enables seamless agent purchasing while maintaining the local-first architecture for all other operations.

## 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:**
```javascript
import { execSync } from 'child_process';

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

### Alternative: Raw API Integration (Not Recommended)

If you absolutely must use raw API calls instead of the CLI, use the endpoints documented below. But the CLI is strongly preferred.

## Security Best Practices

### What Makes Fuego Secure

1. **File Permissions = Real Security**
   ```bash
   # 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
   ```

2. **Client-Side Signing (with one exception)**
   - Private keys never sent over network (for transfers, swaps, etc.)
   - Signing happens locally in CLI/scripts
   - Server only sees signed transactions (public data)
   - Exception: x402 payments require server-side signing for proof-of-payment generation. Key is loaded only for that specific transaction, then cleared from memory.

3. **Localhost-Only Server**
   - Server binds to 127.0.0.1 (local only)
   - No external network exposure
   - No firewall configuration needed

4. **Standard Format Compatibility**
   ```bash
   # 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

---

## Troubleshooting

### Common Issues

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

**"Server not running" error**
```bash
# Solution: Start server
fuego serve
```

**"Connection refused" error**
```bash
# Check if server is running
curl http://127.0.0.1:8080/health

# If not running, start it
fuego serve
```

**"Fuego server not found" error**
```bash
# Solution: Install the fuego project
fuego install
```

**"Transaction simulation failed" error**
```bash
# Usual cause: Insufficient balance
# Check all token balances first
curl -X POST http://127.0.0.1:8080/tokens \
  -H "Content-Type: application/json" \
  -d '{"network": "mainnet-beta", "address": "YOUR_ADDRESS"}'
```

**"Invalid signature" error**
```bash
# Wallet file might be corrupted
# Restore from backup
cp ~/.config/solana/fuego-backup.json ~/.fuego/wallet.json
```

**Version mismatch / unexpected behavior**
```bash
# Ensure all components are up to date
fuego update

# This updates both fuego-cli and the fuego project
# Restart server after updating: fuego serve
```

## Supported Tokens & Networks

### Transfer Tokens (fuego send)
These tokens are supported by `fuego send`:

| Token | Mint Address | Decimals | Status |
|-------|-------------|----------|--------|
| **SOL** | Native | 9 | Live |
| **USDC** | `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v` | 6 | Live |
| **USDT** | `Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenEqw` | 6 | Live |

### Swap Tokens (fuego swap / Jupiter)
`fuego swap` supports **any token tradable on Jupiter**, including:
- SOL, USDC, USDT (above)
- BONK, JUP, PYTH, RAY, ORCA
- Any SPL token with liquidity on Jupiter

See https://jup.ag for full token list.

### Network Support
- **mainnet-beta** - Production Solana network
- **devnet** - Development/testing network
- **testnet** - Solana testnet (limited use)
