Verify a contract

Submit standard Solidity source and compiler settings — this is compiled with real Foundry (forge build) and compared byte-for-byte against what's actually deployed at the address on Vamp Launch Demo. Every vampchain's genesis is permanently capped at the London EVM fork, so evm_version is always submitted as london — if your local build targets a later fork (the default for solc 0.8.20+ unless pinned), recompile with evm_version = "london" first or verification will correctly fail rather than silently pass.

Prefer Foundry directly? forge verify-contract <address> <Contract> --chain 1025207384 --verifier custom --verifier-url {verifier-url}/etherscan-compat/api/1025207384 works unmodified against this same service.
