Additional Details

In general I have been unable to verify contracts that aren't compiled with zksolc and instead just target the standard interpreted evm. In the api schema there doesn't seem to be a flag for this, https://block-explorer-api.mainnet.zksync.io/docs#/Contract%20API/ApiController_verifyContractSourceCode

this looks close to matter-labs/zksync-era#4779 and the follow-up fix in matter-labs/zksync-era#4785.

That thread is specifically about EVM-emulated / non-zksolc verification on Era mainnet with Foundry/solc payloads and the same verifier backend, so I’d start there before treating this as a missing schema flag.

Small caveat: I only checked the public issue/PR plus the current Swagger shape here. If your failure status is different from internal error, posting the GUID/status response is probably the useful bit because maintainers can grep verifier logs for it.

Hey @max-wickham , thanks for reporting this. There was a bug fixed in this PR . You can verify EVM contracts with foundry for example.
To verify a contract on ZKsync Era Sepolia Testnet:

forge verify-contract {contract_address} {contract_path} --chain-id 300 --verifier etherscan --verifier-url https://block-explorer-api.sepolia.zksync.dev/api --etherscan-api-key "abc" --constructor-args {constructor_args}.
