This is a contract development SDK to speed up testing, and hardhat related workflows.

Install using --

yarn add -D brahma-sdk

or

npm install --save-dev brahma-sdk

• Mining blocks

  const mineBlocks = async (_numberOfBlocks: BigNumberish): void

• Setting block timestamp

  const setBlockTime = async (timestamp: number): void

• Switching hardhat network

  const switchToNetwork = async (jsonRpcUrl: string, blockNumber?: number): void

• Getting a signer, with (optionally) address and (optionally) balance. If no address is passed, a default signer is returned

getSigner<T = any>(balance?: BigNumber,address?: string): Promise<T>

The return type is generic for use with any Signer type.

• Get signature with address, signer and verifying contract

async function getSignature(addressToAuthorize: string, signer: Wallet | SignerWithAddress,verifyingContract: string): Promise<string>

• Getting a random wallet

const randomWallet = async (): Promise<Wallet

• Getting a random BigNumber object, with an upper bound and (optionally) lower bound

const randomBN = (upper: BigNumber,lower: BigNumber = BigNumber.from(0)): BigNumber

• Getting an instance of an ERC20 contract with given address

const getERC20ContractAt = async (address: string): Promise<ERC20>

• Getting an instance of WETH contract

const getWETHContract = async (address = Addresses.EthMaxi.wantTokenL1): Promise<IWETH9>

• These are the constant addresses of contracts related to the products --

  Common,
  EthMaxi,
