contract-verification

To verify a deployed smart contract on Etherscan using Forge, you run forge verify-contract with the deployed address, provide the source path, and supply the required block explorer API keys. This ensures source transparency and trust for users.

Source flattening for multi-file contract verification combines imported dependencies into a single file. This process is required by block explorers like Basescan and Arbiscan to match compiler settings and confirm the deployed bytecode corresponds to the provided source code.

Yes, you can verify proxy contracts across block explorers automatically. The workflow supports proxy verification by matching implementation addresses and encoding constructor arguments to satisfy explorer requirements for multi-file deployments.

Encoding constructor arguments for contract verification on Arbiscan involves formatting the initialization inputs into the ABI-encoded hex string expected by the explorer. Matching these encoded arguments and compiler settings ensures your deployed contract passes verification.

Contract verification on Basescan fails when there is a mismatch between the deployed bytecode and the submitted source code. This usually happens due to incorrect compiler settings, improperly encoded constructor arguments, or unflattened multi-file dependencies.
