What This Skill Does

The usdc-dance-evvm-payment skill enables OpenClaw AI agents to conduct secure, autonomous payments using USDC Krump (USDC.k) on the Story Aeneid EVVM via the x402 protocol. By leveraging the EVVM Core (ID 1140) and supporting both the EVVM Native adapter and legacy bridge adapters, this skill provides a robust infrastructure for agent-to-agent financial interactions. It is designed for developers building decentralized applications, automated payment flows, and high-frequency settlement systems on Story Aeneid. Crucially, the skill adheres to a strict security model where it does not store credentials; it relies on environment-provided Privy credentials or private keys to authorize transactions, ensuring the user maintains control over their assets and signing capabilities.

Installation

To integrate this skill, first ensure you have the OpenClaw environment configured. Install the skill by running the command: clawhub install openclaw/skills/skills/arunnadarasa/usdckrump. After installation, you must configure your environment variables. Open your ~/.openclaw/openclaw.json file and add your credentials:

{
  "env": {
    "vars": {
      "PRIVY_APP_ID": "your-app-id",
      "PRIVY_APP_SECRET": "your-app-secret"
    }
  }
}

It is highly recommended to use Privy server wallets to manage agent keys rather than hardcoding private keys. If using the Native adapter, ensure you have first performed a deposit into the EVVM treasury by running the deposit scripts located in the official USDC Krump repository.

Use Cases

• Automated Service Payments: Facilitate seamless pay-as-you-go microtransactions for AI agents accessing third-party APIs or computational services.
• Agent-to-Agent Settlement: Enable direct, trustless payment routing between autonomous entities for collaborative task completion.
• Bridge Protocol Integration: Interact with existing legacy bridges while simultaneously adopting modern EVVM Native adapter protocols for higher throughput and lower overhead.
• Policy-Based Spending: Implement granular control over agent financial behavior using Privy-managed spending limits to prevent unauthorized or runaway expenditures.

Example Prompts

1. "Pay 500 USDC.k to the service agent at address 0xabc... using the EVVM Native adapter."
2. "Check the status of my recent payment with receipt ID 0x123... on the Story Aeneid network."
3. "Deposit 1000 USDC.k into the EVVM treasury to prepare for upcoming agent service payments."

Tips & Limitations

Always prioritize Privy-managed wallets over raw private keys to benefit from built-in security policies and guardrails. Remember that the Native adapter relies on internal EVVM ledger balances; failure to deposit funds beforehand will result in transaction rejection. Use the checkPaymentStatus utility to verify transaction finality before confirming receipt of services. Ensure your environment variables are correctly loaded before initiating any payment commands, and refer to the GitHub repository for the most recent updates on adapter addresses.
