nexwave-gateway

What This Skill Does

The nexwave-gateway skill transforms how OpenClaw agents interact with liquidity. By leveraging Circle Gateway and Programmable Wallets, it provides a unified USDC balance that exists across multiple blockchain ecosystems simultaneously. Unlike traditional bridges that rely on liquidity pools and long wait times, the Gateway utilizes a burn-mint attestation flow. When you deposit USDC into the Gateway contract on any supported chain, the system recognizes your holdings globally in under 500ms. This allows your agent to deposit on Ethereum or Base and instantly mint that same USDC value on Arc Testnet without the standard 15-20 minute bridging overhead.

Installation

To install this skill, use the ClawHub command-line interface. Ensure you have the circle-wallet skill pre-installed, as nexwave-gateway requires existing wallet addresses on ETH-Sepolia, Base-Sepolia, and Arc-Testnet to function correctly. Execute: clawhub install openclaw/skills/skills/botmechanic/nexwave-gateway. After installation, run the setup script located in the skill directory to initialize the required API dependencies and configure your environment variables. Ensure your Circle Developer console keys are properly injected into the .env file to authorize transactions.

Use Cases

• High-Velocity Arbitrage: Move capital between DeFi protocols on different chains instantly as opportunities arise without waiting for bridge finality.
• Multi-Chain Payments: Pay vendors or mint assets on a target chain by drawing from a single, unified source of funds located on your most accessible chain.
• Gas-Efficient Operations: Utilize Arc Testnet as a liquidity hub where USDC serves as the native gas token, eliminating the need to hold multiple native assets for transaction fees.
• Automated Rebalancing: Configure your agent to automatically consolidate USDC across chains into the gateway to ensure high liquidity for upcoming cross-chain transactions.

Example Prompts

1. "Check my total unified USDC balance across all gateway-connected chains and let me know if I have enough to execute a transaction on Arc."
2. "Deposit 50 USDC from my Ethereum Sepolia wallet into the Gateway, then instantly mint that amount on Base Sepolia."
3. "List all supported Gateway chains and current finality status for my linked wallets."

Tips & Limitations

• Chain Finality: While Arc Testnet provides ~0.5s finality, deposits from Ethereum-based chains are subject to the underlying blockchain's confirmation times (up to 20 minutes) before the funds reflect in your unified balance.
• Security: Always verify the Gateway contract addresses listed in the documentation. Never share your entity secrets or private keys.
• Gas Awareness: While Arc uses USDC for gas, remember that initiating deposits from Ethereum or Base still requires native ETH for gas fees.
