# Truffle Configuration File

Use this sample Truffle configuration file to deploy your smart contracts to Basechain.

# Connect to Basechain

You can use this snippet to connect to Basechain:

import {
  Client,
  LocalAddress,
  CryptoUtils,
  LoomProvider,
  createDefaultTxMiddleware
} from 'loom-js'
import Web3 from 'web3'

// ... content omitted for brevity

const client = new Client(networkId, writeUrl, readUrl)
client.on('error', msg => {
  console.error('Error on connecting to Basechain', msg)
  })
client.txMiddleware = createDefaultTxMiddleware(client, privateKey)

// ... content omitted for brevity

const privateKey = CryptoUtils.generatePrivateKey()
const publicKey = CryptoUtils.publicKeyFromPrivateKey(privateKey)
const currentUserAddress = LocalAddress.fromPublicKey(publicKey)

// ... content omitted for brevity

const web3 = new Web3(new LoomProvider(client, privateKey))

If you want to use Universal Signing instead, see our guide on universal signing.

# Ethereum Integration

Contracts deployed on Ethereum

• Transfer Gateway: 0xe080079ac12521d57573f39543e1725ea3e16dcc (use this for Eth, ERC721, and ERC20 assets)
• Loom Transfer Gateway: 0xfcF1E3fA575A313fd81feA2caA06269B49F1A528

Contracts deployed on Plasmachain

• Transfer Gateway

You can resolve the address of the Ethereum transfer gateway by name as follows:

const contractAddr = await client.getContractAddressAsync('gateway')

• Loom Transfer Gateway

You can resolve the address of the Ethereum transfer gateway by name as follows:

const contractAddr = await client.getContractAddressAsync('loomcoin-gateway')

Top 100 ERC20 smart contracts deployed to Loom

We've already deployed to Loom the top 100 smart contracts. See the full list here.

EthCoin

If you transfer Eth to your Basechain account, it'll get deposited into the EthCoin contract:

Instantiate the contract like this:

import {
  Contracts
} from 'loom-js'

// ... content omitted for brevity

const EthCoin = Contracts.EthCoin
const ethCoinInstance = await EthCoin.createAsync(client, currentUserAddress)

Then, you can check the balance as follows:

const balance = await ethCoinInstance.getBalanceOfAsync(currentUserAddress.toString())

Resolve the address by name with:

const contractAddr = await client.getContractAddressAsync('ethcoin')

# Binance Integration

• Binance Hot Wallet address: bnb17mxq8p5jmw27dtt6s92fd35yltdml6snw3r98t

Contracts deployed on Plasmachain

• Transfer Gateway

You can resolve the address of the Binance transfer gateway by name as follows:

const contractAddr = await client.getContractAddressAsync('binance-gateway')

Instantiate the Binance transfer gateway contract like this:

import { BinanceTransferGateway } from 'loom-js/dist/contracts'

// .. content omitted for brevity

const binanceTransferGatewayContract = await BinanceTransferGateway.createAsync(
  client,
  currentUserAddress
)

# Tron Integration

Contract deployed on Tron

• Transfer Gateway: TYmF4Cbz7encD8HnBHHzWHW2B6Q6Y6qgZB

Contract deployed on Basechain

You can resolve the address of the Tron transfer gateway by name as follows:

const contractAddr = await client.getContractAddressAsync('tron-gateway')

• TRX Coin

If you deposit TRX tokens to the Tron transfer gateway, the assets will get transferred into the TRXCoin smart contract deployed on Basechain.

Use something like the following to instantiate the contract:

const loomWeb3 = new Web3(new LoomProvider(client, privateKey))
const trxCoinContractAddress = `0x75c1c1a809a3f3050253e8dce004dc654b5b7fa0`
const trxCoinContract = new loomWeb3.eth.Contract(TRXToken.abi, trxCoinContractAddress)

The TRXToken.abi file can be found here.
