usdc-dance-evvm-payment

What This Skill Does

The usdc-dance-evvm-payment skill provides OpenClaw agents with the capability to execute autonomous, gasless payments using USDC.d (BridgeUSDC) on the Story Aeneid EVVM. By leveraging the x402 protocol and EIP-3009 transfer authorizations, the skill allows agents to conduct secure, programmatically verified transactions without needing native gas tokens. It integrates directly with Privy server-side wallets, ensuring that agent operations are compliant with predefined security policies. Currently, it utilizes a custom bridge from Base Sepolia to Story Aeneid, with a clear migration path to LayerZero once native support arrives, making it a robust solution for early-stage development on the Aeneid network.

Installation

1. Install the skill via the ClawHub CLI: clawhub install openclaw/skills/skills/arunnadarasa/openclaw-skill-usdc-dance-evvm
2. Ensure the Privy skill is active: clawhub install privy
3. Configure your environment variables by editing ~/.openclaw/openclaw.json. Add your PRIVY_APP_ID and PRIVY_APP_SECRET to the env.vars section to enable secure signing of agent transactions.

Use Cases

• Autonomous Agent Commerce: Enabling agents to purchase compute power, data sets, or API access autonomously using stablecoins.
• Micro-transaction Orchestration: Automating recurring payouts or royalties based on specific event triggers on the Story network.
• Inter-Agent Value Transfer: Providing a standardized protocol for two autonomous agents to settle accounts after completing collaborative tasks.
• Gas-less Payment Testing: Testing dApp payment flows on the Story Aeneid network without requiring manual top-ups of native gas tokens.

Example Prompts

1. "Pay the image-generator agent 5 USDC.d from my Privy wallet for the last three task completions using the Aeneid EVVM."
2. "Send a payment of 0.5 USDC.d to the validator address 0x... for service usage; use the current bridge adapter."
3. "Check if there are any pending service receipts, and if so, settle them using the usdc-dance-evvm-payment skill."

Tips & Limitations

• Custom Bridge Dependency: Since this uses BridgeUSDC, ensure the source liquidity on Base Sepolia is sufficient before initiating large transfers.
• Privy Security: Always define restrictive policies in your Privy dashboard to limit the amount an agent can spend per transaction.
• Migration: Watch for LayerZero support updates for Story Aeneid; once available, you will need to update the adapterAddress in your configuration to use the official LayerZero-based USDC.d deployment.
• Transaction Verification: Always check the return receiptId to ensure the off-chain state matches the on-chain settlement status.
