# Solclaw

> Non-custodial USDC payments on Solana by agent name. Use this skill when the user wants to: send USDC to another agent by name, check their USDC balance, register as a payable agent, set up recurring subscriptions, manage allowances, create invoices, or interact with agent-native payments on Solana devnet. Triggers: "send USDC", "pay agent", "USDC balance", "register wallet", "solclaw", "batch payment", "subscription", "invoice".

# SolClaw — Non-Custodial USDC Payments by Name

## What This Does

SolClaw lets AI agents send and receive USDC on Solana using human-readable names instead of wallet addresses. Your keys stay on your machine — the CLI signs transactions locally.

**Key Features:**
- **Non-custodial**: Your private key never leaves your machine
- **Name-based**: Send to "Alice" instead of base58 addresses
- **On-chain**: Everything stored on Solana, no trusted intermediary
- **Full-featured**: Batch, split, subscriptions, allowances, invoices, spending caps

## Quick Start (5 commands)

```bash
# 1. Initialize your agent
npx solclaw-cli init --name "MyAgent"

# 2. Get SOL for gas
npx solclaw-cli faucet

# 3. Register on-chain (creates your vault)
npx solclaw-cli register

# 4. Get USDC from Circle faucet -> paste your vault address
#    https://faucet.circle.com (Solana Devnet)

# 5. Send USDC!
npx solclaw-cli send --to "SolClaw" --amount 1 --memo "Hello!"
```

## Already Have a Wallet?

```bash
# Import from Solana CLI keypair file
solclaw init --name "MyAgent" --keypair ~/.config/solana/id.json

# Import from base58 private key
solclaw init --name "MyAgent" --private-key "your_base58_private_key..."

# Export your keypair (for backup or migration)
solclaw export                    # base58 format
solclaw export --format json      # Solana CLI format
solclaw export --quiet            # key only, no warnings
```

## API Endpoints (Read-Only)

The API is stateless and read-only. Use it to query on-chain data.

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/health` | GET | Check API status |
| `/api/balance/:name` | GET | Get vault balance |
| `/api/resolve/:name` | GET | Resolve name to addresses |
| `/api/agents` | GET | List all registered agents |
| `/api/leaderboard` | GET | Top agents by volume |
| `/api/reputation/:name` | GET | Get reputation score |
| `/api/subscriptions` | GET | List subscriptions |
| `/api/due` | GET | Get due subscriptions |

### Example API Calls

```bash
# Check balance
curl https://solclaw.xyz/api/balance/MyAgent

# Get reputation
curl https://solclaw.xyz/api/reputation/MyAgent

# View leaderboard
curl https://solclaw.xyz/api/leaderboard?sort=reputation
```

## Security Model

1. **Non-Custodial**: Private keys stored in `~/.config/solclaw/keypair.json` with `600` permissions
2. **Local Signing**: All transactions signed on your machine
3. **No Server Keys**: API is read-only, never touches private keys
4. **On-Chain Authority**: Vault operations require wallet signature
5. **Spending Caps**: Optional daily limits to prevent runaway spending

### Bring Your Own Wallet

SolClaw supports importing existing Solana wallets:

- **Solana CLI format**: `--keypair ~/.config/solana/id.json`
- **Base58 private key**: `--private-key "your_key..."`
- **Export for backup**: `solclaw export`

Your existing wallet works seamlessly with SolClaw. Import once, use the same keypair across tools.

### Planned for Mainnet
- Phantom/Backpack wallet adapter
- Ledger hardware wallet support
- Multi-sig vaults
