Client SDK: viem first viem is REQUIRED for fee abstraction (ethers.js/web3.js don't support feeCurrency) Use viem/celo for Celo-specific transaction serialization Never use ethers.js for new Celo projects import { createWalletClient, custom } from "viem"; import { celo } from "viem/chains"; const walletClient = createWalletClient({ chain: celo, transport: custom(window.ethereum), }); ### 2. UI & Wallets: thirdweb Use thirdweb SDK for wallet connection and React components ConnectButton supports 500+ wallets including MiniPay Built-in support for Celo chains import { ConnectButton } from "thirdweb/react"; import { celo } from "thirdweb/chains"; ### 3. Fee Abstraction: always offer stablecoin gas Celo's killer feature: pay gas fees in ERC-20 tokens without paymasters or relayers. Use adapter addresses for 6-decimal tokens (USDC, USDT) - adapters normalize decimals Use token addresses directly for 18-decimal tokens (USDm, EURm, REALm) - no adapter needed Requires viem (ethers.js/web3.js don't support feeCurrency) Only works with Celo-native wallets (MiniPay) or custom implementations import { serializeTransaction } from "viem/celo"; import { parseGwei, parseEther } from "viem"; // For 6-decimal tokens (USDC, USDT): use ADAPTER address const USDC_ADAPTER = "0x2F25deB3848C207fc8E0c34035B3Ba7fC157602B"; // For 18-decimal tokens (USDm, EURm): use TOKEN address directly const USDM_TOKEN = "0x765DE816845861e75A25fCA122bb6898B8B1282a"; const serialized = serializeTransaction({ chainId: 42220, gas: 21001n, feeCurrency: USDC_ADAPTER, // or USDM_TOKEN for USDm maxFeePerGas: parseGwei("20"), maxPriorityFeePerGas: parseGwei("2"), nonce: 69, to: "0x1234512345123451234512345123451234512345", value: parseEther("0.01"), }); ### 4. Smart Contracts: Foundry Use Foundry (forge, cast, anvil) for all contract development Fast compilation, powerful testing, built-in fuzzing Native Celo verification support via Celoscan API # Install Foundry curl -L https://foundry.paradigm.xyz | bash && foundryup # Create project forge init my-project && cd my-project # Deploy to Celo Sepolia forge script script/Deploy.s.sol \\ --rpc-url https://forno.celo-sepolia.celo-testnet.org \\ --broadcast --verify ### 5. MiniPay: mobile-first stablecoin UX Detect MiniPay via window.ethereum?.isMiniPay Users have stablecoins (USDm, USDC), not CELO Hide "Connect Wallet" button - connection is implicit Test via MiniPay Site Tester with ngrok function isMiniPay(): boolean { return typeof window !== "undefined" && window.ethereum?.isMiniPay === true; } ### 6. AI Agents: ERC-8004 + x402 For AI agent development on Celo: ERC-8004: On-chain identity, reputation, and trust verification x402: HTTP-native micropayments with stablecoins // Verify agent trust before interaction const summary = await reputationRegistry.getSummary(agentId); if (summary.averageScore >= 80) { // Make paid request to trusted agent const response = await fetchWithPayment(serviceUrl); } ### 1. Classify the task layer | Layer | Tools | |-------|-------| | UI/wallet/hooks | viem + thirdweb | | Scripts/backend | viem directly | | Smart contracts | Foundry (forge) | | MiniPay apps | MiniPay detection + stablecoin UX | | AI agents | ERC-8004 + x402 | ### 2. Pick the right fee currency approach | Scenario | Approach | |----------|----------| | User has MiniPay | Offer fee currency selection | | User has MetaMask | Must pay in CELO (no fee abstraction) | | Server-side/scripts | Always use fee currency with viem | ### 3. Implement with Celo-specific correctness Always be explicit about: Network: Mainnet (42220) vs Sepolia (11142220) Fee currency: Adapter address (6-decimal) vs token address (18-decimal) Wallet compatibility: MiniPay supports fee abstraction, MetaMask does not ### 4. Add tests Test both CELO and fee currency transactions separately Test wallet connection with MiniPay detection For contracts, use forge test with fuzzing For MiniPay apps, test in Site Tester on real device ### 5. Deliverables When implementing changes, provide: Exact files changed Commands to install/build/test/deploy Fee currency addresses used (mainnet vs testnet) Wallet compatibility notes ### Networks | Network | Chain ID | RPC Endpoint | Explorer | |---------|----------|--------------|----------| | Mainnet | 42220 | https://forno.celo.org | https://celoscan.io | | Sepolia | 11142220 | https://forno.celo-sepolia.celo-testnet.org | https://sepolia.celoscan.io | ### Fee Currency Addresses - Mainnet Why adapters? Celo's gas calculations use 18 decimals internally. Tokens with different decimals (like USDC/USDT with 6 decimals) need adapter contracts to normalize the decimal conversion. Native Mento stablecoins (USDm, EURm, REALm) are already 18 decimals, so you use their token address directly. | Token | Decimals | feeCurrency Address | Type | |-------|----------|---------------------|------| | USDC | 6 | 0x2F25deB3848C207fc8E0c34035B3Ba7fC157602B | Adapter | | USDT | 6 | 0x0e2a3e05bc9a16f5292a6170456a710cb89c6f72 | Adapter | | USDm | 18 | 0x765DE816845861e75A25fCA122bb6898B8B1282a | Token (no adapter needed) | | EURm | 18 | 0xD8763CBa276a3738E6DE85b4b3bF5FDed6D6cA73 | Token (no adapter needed) | | REALm | 18 | 0xe8537a3d056DA446677B9E9d6c5dB704EaAb4787 | Token (no adapter needed) | ### Fee Currency Addresses - Celo Sepolia | Token | Decimals | feeCurrency Address | Type | |-------|----------|---------------------|------| | USDC | 6 | 0x4822e58de6f5e485eF90df51C41CE01721331dC0 | Adapter | | USDm | 18 | 0xdE9e4C3ce781b4bA68120d6261cbad65ce0aB00b | Token (no adapter needed) | | EURm | 18 | 0xA99dC247d6b7B2E3ab48a1fEE101b83cD6aCd82a | Token (no adapter needed) | ### Core Protocol Contracts - Mainnet | Contract | Address | |----------|---------| | CELO Token | 0x471EcE3750Da237f93B8E339c536989b8978a438 | | FeeCurrencyDirectory | 0x15F344b9E6c3Cb6F0376A36A64928b13F62C6276 | | Registry | 0x000000000000000000000000000000000000ce10 | ### Stablecoin Tokens - Mainnet | Token | Address | Decimals | |-------|---------|----------| | USDm | 0x765DE816845861e75A25fCA122bb6898B8B1282a | 18 | | EURm | 0xD8763CBa276a3738E6DE85b4b3bF5FDed6D6cA73 | 18 | | USDC | 0xcebA9300f2b948710d2653dD7B07f33A8B32118C | 6 | | USDT | 0x48065fbbe25f71c9282ddf5e1cd6d6a887483d5e | 6 | ### Progressive disclosure (read when needed) Detailed documentation for each topic is available in the celo-org/agent-skills repository: ### Client & Frontend viem - TypeScript client with fee currency support wagmi - React hooks for Celo dApps thirdweb - Full-stack Web3 development evm-wallet-integration - Wallet connection patterns ### Celo Features fee-abstraction - Pay gas with stablecoins minipay-integration - MiniPay Mini App development celo-stablecoins - USDT, USDC, USDm, EURm, BRLm, XOFm, KESm, PHPm, COPm, NGNm, GHSm, GBPm, ZARm, CADm, AUDm, CHFm, JPYm, BRLA, VCHF, VEUR, VGBP, USDGLO, agEURA + COPM celo-rpc - Blockchain interaction via RPC ### Smart Contracts evm-foundry - Foundry development (recommended) contract-verification - Celoscan, Blockscout, Sourcify ### AI Agent Infrastructure 8004 - ERC-8004 Agent Trust Protocol x402 - HTTP-native agent payments ### DeFi & Bridging celo-defi - DeFi protocol integration bridging - Asset bridging to/from Celo ### Scaffolding celo-composer - Project templates and scaffolding ### Official Documentation Token Contracts - All token addresses Core Contracts - Protocol contract addresses Fee Currency - Fee abstraction guide MiniPay - Mini App development ### Why Celo?
