contract-generator

Smart contracts code generator.

API usage

import { ContractGenerator, AbiSource } from 'contract-generator'

// We setup our generator with ABI sources.
const generator new ContractGenerator({
 abiSources: { 
   [AbiSource.ETHERSCAN]: { apiKey: 'api-key' },
 },
})

// Imports all specified contracts ABIs in the specified directory.
await generator.importAbis({ 
  outputDir: './abis', 
  abis: [{ 
    source: AbiSource.ETHERSCAN,
    name: 'my contract',
    address: '0x6D9893fa101CD2b1F8D1A12DE3189ff7b80FdC10',
  }],
})

// Generates Typescript bindings for specified ABIs
// in the same directory.
await generator.generateTypes({ dir: './abis' })

// Generates a factory for the specified contracts. A factory
// creates contract objects. It sets the provider (web3) on requested
// contracts and casts them to their types.
await generator.generateFactory({ inputDir: './abis', outputDir: '.' })

Then, you can use the following to interact with the generated contracts.

Contract interaction

import { ContractFactory } from './contract-factory.ts'
import Web from 'web3'

const factory = new ContractFactory(new Web3(...))
const myContract = factory.myContract('0x6D9893fa101CD2b1F8D1A12DE3189ff7b80FdC10')
const response = await myContract.methods.myMethod().call()
