SkillMint 💰

Turn your skills into income streams. SkillMint lets OpenClaw agents monetize their skills with USDC micropayments.

Why SkillMint?

Agents build amazing skills but have no way to earn from them. SkillMint creates an economic layer:

• Creators register skills with per-call pricing
• Users pay automatically when invoking paid skills
• Settlement happens in USDC via Circle infrastructure
• Cross-chain support via CCTP (pay from any chain)

Quick Start

For Skill Creators

# 1. Register your skill for monetization
skillmint register my-awesome-skill --price 0.01

# 2. Get your earnings wallet (auto-created via Circle)
skillmint wallet

# 3. Check your earnings
skillmint earnings

For Skill Users

# 1. Fund your SkillMint wallet
skillmint fund 10  # Add 10 USDC

# 2. Use paid skills normally - payment is automatic
# When you call a monetized skill, SkillMint handles payment

# 3. Check your usage
skillmint usage

Payment Flow

1. User invokes paid skill
2. SkillMint checks balance → sufficient funds?
3. Deduct from user wallet (Circle DCW)
4. Credit to creator wallet (Circle DCW)
5. Log usage for analytics
6. Execute skill and return result

Cross-Chain Support

SkillMint uses Circle's CCTP + Forwarder for cross-chain payments:

• Pay from any supported chain (Base, Polygon, Arbitrum, etc.)
• Creator receives on their preferred chain
• Automatic bridging — no manual claiming

Economics

| Fee Type | Amount | Recipient | |----------|--------|-----------| | Skill Price | Set by creator | Creator (95%) | | Platform Fee | 5% | SkillMint Treasury | | Gas | Sponsored | Circle Gas Station |

Gas-free transactions via Circle Gas Station — creators and users don't pay gas!

Example: Monetizing an SEO Skill

# Creator registers their SEO analysis skill
$ skillmint register seo-analyzer --price 0.05
✓ Registered seo-analyzer at $0.05/call
✓ Wallet created: 0x1234...abcd (ARC-TESTNET)

# User calls the skill (payment automatic)
$ openclaw "analyze SEO for my site"
[SkillMint] Charged 0.05 USDC for seo-analyzer
[seo-analyzer] Your SEO score is 78/100...

# Creator checks earnings
$ skillmint earnings
seo-analyzer: 127 calls = 6.35 USDC (6.03 after fees)

Supported Chains

Leveraging Circle's multi-chain infrastructure:

| Chain | Status | Token | |-------|--------|-------| | ARC Testnet | ✅ Default | USDC | | Base Sepolia | ✅ | USDC | | Polygon Amoy | ✅ | USDC | | Arbitrum Sepolia | ✅ | USDC | | Ethereum Sepolia | ✅ | USDC |

Security

• Testnet only — Do not use mainnet credentials
• No custody — Circle manages wallet keys securely
• Transparent — All transactions verifiable on-chain
• Rate limits — Prevent abuse and runaway costs

Configuration

Config stored in ~/.openclaw/skillmint/config.json:

{
  "defaultChain": "ARC-TESTNET",
  "maxPerCall": 1.0,
  "autoFund": false
}

Integration with circle-wallet

SkillMint builds on the circle-wallet skill. If you have existing Circle wallets, SkillMint can use them:

skillmint config --wallet 0x1234...  # Use existing wallet

API (for Skill Developers)

Integrate SkillMint into your skill:

// In your skill's code
const skillmint = require('skillmint');

// Check if caller has sufficient balance
const canPay = await skillmint.checkBalance(callerId, 0.05);

// Charge for the call
await skillmint.charge(callerId, skillName, 0.05);
