Creating a payment stream with Sablier

sablier-contract-call.js

// yarn add bignumber.js
// import BigNumber from 'bignumber.js'
// BigNumber.config({ EXPONENTIAL_AT: 30 })   <--- add this after your imports, it will prevent the number from being formatted like "1e+21"

// call this when the user presses the "Create Stream" button
const sablier = new ethers.Contract(addresses[chainId].sablier, abis.sablier, getProviderOrSigner(library, account))

let convertedDeposit = new BigNumber(deposit).multipliedBy(10 ** 18).toFixed(0)
let remainder = new BigNumber(convertedDeposit) % (convertedStopTime - convertedStartTime)
let amountToDeposit = new BigNumber(convertedDeposit).minus(remainder).toString()

const token = new ethers.Contract("0xc3dbf84abb494ce5199d5d4d815b10ec29529ff8", abis.erc20, getProviderOrSigner(library, account));

await approveTx.wait();
