Viem for Celo provides type-safe chain configuration and client setup for Celo mainnet and Sepolia testnet. Install viem via npm, configure a public or wallet client using Viem's Celo chain definitions, and use TypeScript's type system to catch errors during development and contract interactions.

Can I pay gas fees with USDC or USDT on Celo?▼

Yes. Viem for Celo supports CIP-64 transaction handling and fee currency configuration, enabling you to pay gas with USDC or USDT instead of the native asset. Configure the fee currency in your transaction objects when signing and submitting transactions.

Install Viem via npm and integrate it into a TypeScript project. You need Viem's Celo chain definitions and a transport layer (e.g., http endpoint). No additional blockchain tools are required; Viem handles type-safe interactions with mainnet and testnets.

Does Viem work with both Celo mainnet and testnet?▼

Yes. Viem for Celo supports both Celo mainnet and Sepolia testnet through built-in chain definitions. Switch between networks by selecting the appropriate chain configuration when instantiating your public or wallet client.
