celo-dev

What This Skill Does

The celo-dev skill provides a comprehensive development playbook for building on the Celo blockchain as of February 2026. It serves as an expert assistant for developers building decentralized applications (dApps), smart contracts, and AI agents within the Celo ecosystem. The skill enforces a modern, opinionated technology stack: it mandates the use of viem for all transaction and client-side logic to ensure native fee currency support (CIP-64), utilizes thirdweb for efficient wallet connectivity, and leverages Foundry for robust smart contract development. It is specifically designed to handle Celo's unique capabilities, such as paying gas in stablecoins (USDC, USDT, USDm), MiniPay integration, and advanced AI-agent infrastructure including ERC-8004 identity and x402 payment handling.

Installation

To integrate this skill into your environment, run the following command in your terminal: clawhub install openclaw/skills/skills/viral-sangani/celo-agent-skills

Use Cases

• Frontend Development: Building React and Next.js applications that require seamless wallet connections via thirdweb, including support for mobile-first wallets like MiniPay.
• Transaction Logic: Implementing fee abstraction where users can pay gas costs in stablecoins rather than native CELO, utilizing viem's transaction serialization.
• Smart Contract Development: Creating, testing, and deploying contracts using Foundry's high-performance testing and fuzzing capabilities.
• AI Agent Integration: Developing autonomous agents that require ERC-8004 reputation management and x402 payment flows for cross-agent economic interactions.
• Token Economics: Integrating Mento stablecoins and cross-chain bridged assets into dApp workflows.

Example Prompts

• "Can you help me initialize a new Foundry project for a Celo smart contract and show me how to verify it on Celoscan?"
• "Write a React component using thirdweb's ConnectButton that allows users to select USDC as their fee currency for a transaction using viem."
• "How do I configure my viem wallet client to serialize a transaction that pays gas using the USDC adapter on Celo mainnet?"

Tips & Limitations

• Requirement Priority: Always prioritize viem over ethers.js. The skill will enforce this because viem is the only library that natively handles the feeCurrency field required for CIP-64 gas abstraction.
• Stablecoin Specifics: Remember to distinguish between 6-decimal tokens (requires the adapter address) and 18-decimal tokens (use the token address directly). Using the wrong address will cause transaction revert errors.
• AI Infrastructure: Ensure your agent environment is set up for ERC-8004, as this is the standard for identity and reputation within the ecosystem. The skill documentation provides standard patterns for x402 payment flows which should be followed to ensure interoperability.
