Verify smart contracts

Verify Solidity contracts on ADI Mainnet and ADI Network AB Testnet.

Use the working Blockscout explorers to publish and verify contract source code. Blockscout is open, so verification does not require an API key.

Choose an explorer

Network	Verification status	Chain ID	API URL
Primary mainnet explorer	Broken	36900	—
BLS mainnet explorer	Working	36900	https://explorer-bls.adifoundation.ai/api
ADI Network AB Testnet explorer	Working	99999	https://explorer-api.ab.testnet.adifoundation.ai/api

Use the BLS explorer for ADI Mainnet. Use the testnet explorer for ADI Network AB Testnet. The primary mainnet explorer cannot verify contracts.

The BLS explorer runs Blockscout with the smart-contract-verifier and Sourcify backend.

Verify in the explorer

1. Open the working explorer for your network.

2. Paste the deployed contract address into the search field.

3. Open the Contract tab.

4. Select Verify & Publish.

5. Select the compiler version and license.

6. Upload your source using one of these formats:

   • A single Solidity file.

   • Multiple source files.

   • Standard JSON input.

Use the exact compiler version, optimizer settings, and constructor arguments from deployment.

Foundry

Configure the BLS explorer in foundry.toml. The empty key is intentional. Blockscout does not require an API key.

[etherscan]
adi = { key = "", url = "https://explorer-bls.adifoundation.ai/api", chain = 36900 }

Deploy and verify on ADI Mainnet:

forge create --verify --chain 36900 src/Contract.sol:Contract

Or explicitly select Blockscout:

forge create --verify --verifier blockscout \
  --verifier-url https://explorer-bls.adifoundation.ai/api \
  --chain 36900 src/Contract.sol:Contract

For ADI Network AB Testnet, use chain ID 99999 and its API endpoint:

[etherscan]
adiTestnet = { key = "", url = "https://explorer-api.ab.testnet.adifoundation.ai/api", chain = 99999 }

forge create --verify --verifier blockscout \
  --verifier-url https://explorer-api.ab.testnet.adifoundation.ai/api \
  --chain 99999 src/Contract.sol:Contract

Hardhat

Configure hardhat-verify with custom ADI network definitions. Empty API keys are correct for Blockscout.

require("@nomicfoundation/hardhat-verify");

module.exports = {
  networks: {
    adi: {
      url: "https://rpc.adifoundation.ai",
      chainId: 36900,
    },
    adiTestnet: {
      url: "https://rpc.ab.testnet.adifoundation.ai",
      chainId: 99999,
    },
  },
  etherscan: {
    apiKey: {
      adi: "",
      adiTestnet: "",
    },
    customChains: [
      {
        network: "adi",
        chainId: 36900,
        urls: {
          apiURL: "https://explorer-bls.adifoundation.ai/api",
          browserURL: "https://explorer-bls.adifoundation.ai",
        },
      },
      {
        network: "adiTestnet",
        chainId: 99999,
        urls: {
          apiURL: "https://explorer-api.ab.testnet.adifoundation.ai/api",
          browserURL: "https://explorer.ab.testnet.adifoundation.ai",
        },
      },
    ],
  },
};

Then run:

npx hardhat verify --network adi <CONTRACT_ADDRESS> <CONSTRUCTOR_ARGUMENTS>

Verify on ADI Network AB Testnet:

npx hardhat verify --network adiTestnet <CONTRACT_ADDRESS> <CONSTRUCTOR_ARGUMENTS>

The testnet network name is ADI Network AB Testnet. Its chain ID is 99999.

You can also use the blockscout-hardhat-verify plugin. It supports Blockscout verification directly.

Sourcify

Sourcify provides an additional verification backend for the BLS mainnet explorer. You can submit matching contract metadata and source files through Sourcify. The explorer can then display the verified result.
