gstable-ai-payment

What This Skill Does

The gstable-ai-payment skill acts as a financial bridge between AI agents and on-chain payment gateways. It enables agents to autonomously interact with the GStable protocol to facilitate cryptocurrency payments, token approvals, and transaction execution. The skill simplifies the complex steps involved in on-chain settlements—such as balance checking, token allowance management, and EIP-712 session signing—into simple command-line or programmatic operations. By utilizing this skill, an agent can take a payment link provided by a vendor, negotiate the terms, select the appropriate token on the correct chain (such as Polygon or Arbitrum), and complete the transaction without human intervention.

Installation

To integrate this skill into your environment, use the ClawHub CLI. Ensure your environment variables are configured with your private key before execution to enable transaction signing capabilities.

clawhub install openclaw/skills/skills/d5c5ceb0/gstable-ai-payment
cd ~/.openclaw/workspace/skills/gstable-ai-payment
uv sync
export WALLET_PRIVATE_KEY=your_private_key

Use Cases

• Autonomous E-commerce: Allow an AI agent to shop online and pay for services automatically once a cart is finalized.
• Subscription Management: Automate recurring crypto payments for digital services or API access tokens.
• Freelance Settlements: Enable agents representing a developer to settle invoices or escrow payments automatically after confirming the delivery of code.
• Cross-Chain Arbitrage Payments: Pay vendors across multiple supported chains like Base or Ethereum using a unified agent workflow.

Example Prompts

1. "Check the details for payment link lnk_BUDBgiGTWejFs8v0FbdpR3iJ83CG1tua and confirm if I have enough USDC on Polygon to pay for it."
2. "Create a payment session for lnk_QTAfGfyqAZHGSm9NKLhtjNYu8dNHRpGh using 50 USDC on the Polygon network."
3. "Execute the full payment process for the latest invoice provided by GStable for my account on the Arbitrum network."

Tips & Limitations

• Security: The WALLET_PRIVATE_KEY is highly sensitive. Ensure it is never committed to git or exposed in clear text logs. Use environment files or secret managers.
• Approval Management: Always verify the allowance status before execution to avoid failed transactions due to insufficient gas or spending permissions.
• Network Support: Currently supports Polygon, Ethereum, Arbitrum, and Base. Always ensure your agent is pointed to the correct chain_id for your specific payment link to avoid loss of funds.
