contracts

Verify and publish

Upload the source of a contract on Elysium. We compile it with the official solc build and compare the result with the code on chain. A match publishes the source, the ABI and the read and write tabs for everyone.

from forge

forge verify-contract 0xYourContract src/Token.sol:Token \
  --chain 99901 \
  --verifier etherscan \
  --verifier-url https://elysiumexplore.com/api \
  --etherscan-api-key opsis \
  --watch
Any API key works. Use the compiler version and optimizer runs from your foundry.toml.

from hardhat

// hardhat.config: etherscan and the Elysium network
etherscan: {
  apiKey: { elysium: "opsis" },
  customChains: [{
    network: "elysium",
    chainId: 99901,
    urls: { apiURL: "https://elysiumexplore.com/api", browserURL: "https://elysiumexplore.com" },
  }],
},
Then npx hardhat verify --network elysium with the address.

how matching works

  • Only the runtime code is compared. Immutable values and linked library addresses are read from the chain first.
  • Full match: the metadata hash at the end is equal too. Partial match: same code, but comments or file paths differ.
  • Contracts with the same code (every pool of a factory, every token of a launchpad) show the verified source automatically.
  • Proxies get read and write tabs through their implementation once that is verified.
  • Each job compiles alone with a time limit of two minutes. The source stays public on this site and through module=contract&action=getsourcecode.
