4Claw Mint

Mint 4Claw (symbol: 4) tokens on BSC. Only OpenClaw agents can mint — the contract requires a signature from the authorized signer service.

Token Info

• Name: 4Claw, Symbol: 4
• Chain: BSC (Chain ID: 56)
• Contract: 0x5F4E6Ee459fA71C226131BCeD5694aAab3b481dB
• Total Supply: 1,000,000
• Public Mint: 600,000 (100 per mint, 6000 total mints)
• LP Reserve: 400,000 (pre-minted to deployer)
• Cooldown: 15 minutes per wallet

How It Works

1. Agent calls the signer service with its wallet address
2. Service checks cooldown, generates nonce + deadline, signs the mint authorization
3. Agent submits the signature to the on-chain contract
4. Contract verifies signature, enforces cooldown, mints 100 tokens

Mint

Run the mint script with the agent's wallet private key:

node scripts/mint.js \x3CPRIVATE_KEY> \x3CSERVER_URL>

• PRIVATE_KEY: Agent's BSC wallet private key (needs small BNB for gas)
• SERVER_URL: Signer service URL (default: http://43.160.201.224:3456)

The script handles everything: request signature → send tx → confirm → report balance.

Signer Service

The signer service must be running for mints to work. It validates requests and signs mint authorizations.

SIGNER_PRIVATE_KEY=0x... CONTRACT_ADDRESS=0x... node scripts/server.js

Endpoints:

• POST /api/mint-signature — Request a mint signature. Body: {"wallet_address": "0x..."}
• GET /api/status — Check service status

Contract

Source: references/FourClaw.sol

Key functions:

• mint(nonce, deadline, signature) — Mint 100 tokens (requires valid signer signature)
• lastMintTime(address) — Check when an address last minted
• mintRemaining() — How many public mint tokens are left
• setSigner(address) — Owner can update the signer address

Setup for Deployer

1. Deploy FourClaw.sol to BSC with constructor args: (signerAddress, lpWalletAddress)
2. Set env vars and start the signer service
3. Share the skill — any OpenClaw agent with a BSC wallet can mint

Error Handling

• Cooldown not elapsed: Wait 15 minutes between mints
• Public mint exhausted: All 600,000 tokens have been minted
• Signature expired: Signature is valid for 5 minutes, retry
• Invalid signature: Signer service may be misconfigured
• Insufficient BNB: Agent wallet needs BNB for gas (~0.001 BNB per mint)
