Embark-etherscan-verifier

Plugin for Embark and library to flatten and verify contracts on Etherscan.

Plugin installation

In your Embark dapp directory:

npm install embark-etherscan-verifier --save or yarn add embark-etherscan-verifier

then add embark-etherscan-verifier to the plugins section in embark.json:

  "plugins": {
    "embark-etherscan-verifier": {}
  }

Usage

Flatten

In the console, type flatten or flatten ContractName(s)

flatten: Flattens all contracts
flatten ContractName(s): Flattens the specified contract(s). For multiple contracts, separate them using a comma.
Example: flatten SimpleStorage,Token

Verify

You can also automatically verify on a valid network (mainnet, ropsten, rinkeby, kovan)

In the console:

verify <API_KEY> <contractName>: Verifies the specified contract (flattens if it was not done before)
- You need an Etherscan API key. You can find a simple tutorial here
- Example: verify YOUR_KEY SimpleStorage

Requirements

Embark 4.0.0 or higher

Library usage

You can use the flattener and verifier standalone.

import FlattenerVerifier from 'embark-etherscan-verifier/lib/FlattenerVerifier`;

const flattenerVerifier = new FlattenerVerifier({
  optimize: true,
  optimizeRuns: 200,
  contractsFiles: [...],
  solcVersion: '0.5.2',
  getWeb3DeployObject: (contract, cb) => {},
  getAllContracts: (cb) => {},
  getContractByName: (contractName, cb) => {},
  getNetworkId: (cb) => {}
});

Parameters

optimize: bool: if the contract is optimized
optimizeRuns: int: Number of optimize passes
contractsFiles: Array of contract files objects. Must contain:
- originalPath: Original path to the contract (relative path)
- path: Absolute path to the contract object
- importRemappings: Array of remapping objects (for imports). Must contain:
  - target: Absolute path to the imported contract
solcVersion: string: solc version used to compile
getWeb3DeployObject: Function to get a web3 deploy object
getAllContracts: Function that returns all contract objects. Contract object must contain: linkReferences(from solc output contract.evm.bytecode.linkReferences)}
- className: string: Class name of the contract
- originalFilename: string: Original file name of the file (relative path)
- filename: string: Complete absolute file path
- deployedAddress: string: Address where the contract is deployed
- linkReferences: object: Library link references. You can get it from the solc output as contract.evm.bytecode.linkReferences
getContractByName: Function to get a contract object by name. Contains the same as all contracts above
getNetworkId: Function that returns the current networkId
