Verify contracts on Celo

Using Foundry

If you deployed with Foundry, verify with forge verify-contract. Set your API key first — get one at etherscan.io/register:

export ETHERSCAN_API_KEY=<your etherscan API key>

Celo Mainnet (chain ID 42220):

forge verify-contract --chain-id 42220 <contract_address> <contract_location> --etherscan-api-key $ETHERSCAN_API_KEY --watch

Celo Sepolia testnet (chain ID 11142220):

forge verify-contract --chain-id 11142220 <contract_address> <contract_location> --etherscan-api-key $ETHERSCAN_API_KEY --watch

Passing --verify to forge create or forge script verifies right after deployment using the same ETHERSCAN_API_KEY. A [etherscan] block in foundry.toml is only needed to point Foundry at a custom verifier URL.
