v0.7.0

Breaking usage changes

• Contract deployment needs to be done through an account (invoking UDC under the hood):

const contractFactory = starknet.getContractFactory(...);

// old
await contractFactory.deploy({ args }, { options });

// new
const account = ...;
await account.declare(contractFactory);
await account.deploy(contractFactory, { args }, { options });

• Accounts:
  • starknet.getAccountFromAddress and starknet.deployAccount are history
  • Separate account creation and deployment
  • To be able to deploy an ArgentAccount, the chain you are using is expected to have ArgentAccount contracts declared. If you are using Devnet, this is most easily achievable by running a Devnet forked from e.g. alpha-goerli.

import { starknet } from "hardhat";
const account = await starknet.OpenZeppelinAccount.createAccount(...);
// somehow fund account.address
// ...
await account.deployAccount();

// alternatively
const account = await starknet.OpenZeppelinAccout.getAccountFromAddress(...);

// same for starknet.ArgentAccount - no longer requires separate initialization

• Implicitly calculate invocation max fee:

// maxFee will be `1 + overhead` times the estimated fee; if overhead not provided, the default 0.5 is used.
// For example this is how a 40% overhead is specified:
await account.invoke(contract, "foo", { arg1: ... }, { overhead: 0.4 });

• Fix return type of StarknetContract.decodeEvents (no longer a Promise)
• Make --account-contract of hardhat starknet-verify a flag rather than a param
• Remove redundant CLI commands
  • Namely: hh starknet-deploy, hh starknet-call, hh starknet-invoke, hh starknet-estimate-fee
  • Done after consulting with users - nobody was against removal
  • All those commands have their JS/TS counterparts
  • If you really need CLI, you can Starknet CLI
• You are welcome to take a look into the examples in the docs and in the example repo.
