Smart Contract Deploy & Verify

Deploy contracts exactly as you would on BSC — only the network config changes.

Foundry​

forge create src/MyContract.sol:MyContract \
  --rpc-url https://rpc-testnet.mo.fit \
  --private-key $PRIVATE_KEY

Verify on Blockscout:

forge verify-contract <address> src/MyContract.sol:MyContract \
  --verifier blockscout \
  --verifier-url https://scan-testnet.mo.fit/api

Hardhat​

// hardhat.config.ts
export default {
  networks: {
    moTestnet: {
      url: 'https://rpc-testnet.mo.fit',
      chainId: 6688,
      accounts: [process.env.PRIVATE_KEY!],
    },
  },
  etherscan: {
    apiKey: { moTestnet: 'blockscout' },
    customChains: [{
      network: 'moTestnet',
      chainId: 6688,
      urls: {
        apiURL: 'https://scan-testnet.mo.fit/api',
        browserURL: 'https://scan-testnet.mo.fit',
      },
    }],
  },
};
npx hardhat run scripts/deploy.ts --network moTestnet
npx hardhat verify --network moTestnet <address> <constructorArgs...>

Remix​

Set the injected provider to Mo Chain Testnet (after adding the network), then deploy as usual.

Verification notes​

  • Blockscout runs a smart-contract-verifier microservice that fetches the matching solc automatically.
  • Match the exact compiler settings: Foundry 0.8.20 defaults to shanghai EVM version (not paris); older OpenZeppelin/solc 0.5.x standard-input must omit metadata.bytecodeHash.
