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:

Sign up at https://portal.jup.ag
Create a new API key (free tier available)
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

text

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

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

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

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
