Hello Fabijan and welcome!
The repo for the Starknet Hardhat plugin is here [GitHub - Shard-Labs/starknet-hardhat-plugin: A plugin for integrating Starknet tools into Hardhat projects](https://github.com/Shard-Labs/starknet-hardhat-plugin)
An example can be found here [GitHub - Shard-Labs/starknet-hardhat-example: Examples of how Starknet Hardhat plugin can be used.](https://github.com/Shard-Labs/starknet-hardhat-example)

For developers using this plugin on Windows, have you been getting weird logs lately (might be docker related)? Or maybe getting assert failure when running the `test` task?

New version (v0.3.3) has been released:

Changes:
- Have an Alpha Mainnet config entry the same way Alpha Testnet is present (i.e. `alpha` and `alphaMainnet` are available without defining in your hardhat config file; it was a bit late when it was realized that `alphaMainnet` is not the best choice, and future versions will have `alpha-mainnet` by default).
- Use cairo-lang v0.6.1 by default.
- When waiting for transactions to become `PENDING`, also check for their `block_hash` to become NOT `pending`.
Feature requests on hold, but hopefully one of them will be supported in the next version:
- usage of an existing venv instead of necessarily running a docker container
- verification task (voyager)

New version (v0.3.4) has been released:

Changes:
- Allow user to use existing or active Python environment (avoids using Docker).
- Improve error reporting on non-existence of artifacts directory.
Example 1 (hardhat.config.ts):
```typescript
module.exports = {
cairo: {
// if created with python -m venv path/to/my-venv
venv: "path/to/my-venv"
}
}
```
Example 2 (hardhat.config.ts):
```typescript
module.exports = {
cairo: {
// use the already activated env
venv: "active"
}
}
```

New version (v0.3.5) has been released ([GitHub](https://github.com/Shard-Labs/starknet-hardhat-plugin/releases/tag/v0.3.5)):
- Add `starknet-verify` task:
- Enables verifying contracts on [Voyager](https://voyager.online/) through CLI instead of just through [UI](https://voyager.online/verifyContract)
- Suggested by @maciejka.
- Add `--wait` flag to `starknet-deploy` task:
- Allows waiting until deployment becomes at least `PENDING`.
- Handle error arising on using Python virtual environment without `cairo-lang`.
- Improve `getContractFactory` (the function that creates a contract factory from the provided contract):
- Handle ambiguous input.
- Allow specifying the contract by the path of its source.

- when awaiting transactions, they are resolved when ACCEPTED\_ON\_L2)
- have both `alpha` and `goerli-alpha` as predefined network names for Alpha Testnet (on Goerli)
- Use `alpha-mainnet` as the predefined network name of Alpha Mainnet.
- Improve Readme.

- Support for Accounts/Wallets:
- configure it in your hardhat.config file: [https://github.com/Shard-Labs/starknet-hardhat-plugin/#wallet](https://github.com/Shard-Labs/starknet-hardhat-plugin/#wallet)
- `starknet-deploy-account` task: [https://github.com/Shard-Labs/starknet-hardhat-plugin/#starknet-deploy-account](https://github.com/Shard-Labs/starknet-hardhat-plugin/#starknet-deploy-account)
- in Mocha tests: [https://github.com/Shard-Labs/starknet-hardhat-example/blob/master/test/wallet-test.ts](https://github.com/Shard-Labs/starknet-hardhat-example/blob/master/test/wallet-test.ts)
- **IMPORTANT** : The new developer experience of using `invoke` or `call` in Mocha is compromised by this (three optional parameters in a row) - this will be changed in 0.4.0.
- Target pending block by default when making calls.
- `cairo_path` option used by `starknet-compile` is configurable in hardhat.config.
- Retry status checking if received 503 response.
- Increase status checking timeout to reduce network load.

- Expand tilde (~) to homedir in venv path.
- Add Docker issue fix to Readme.
- **BREAKING** changes:
- Rename string utility functions to reflect their real purpose (functionality stays the same, the name changes):
- `stringToBigInt` → `shortStringToBigInt`
- `bigIntToString` → `bigIntToShortString`
- Change the expected config file structure (check [here](https://github.com/Shard-Labs/starknet-hardhat-example/blob/7d2979eb14ab8e6a1e1e2983585eca5b43647517/hardhat.config.ts) for an example):
- Use `starknet` key.
- Stop using `cairo` key:
- Rename `version` to `dockerizedVersion`:
- Because the `version` key affected and affects only the Docker image used (if user opts for dockerized mode).
- Move `wallets` key to `starknet`.
- Rename `starknetNetwork` to `network` and move it from `mocha` to `starknet`:
- This is because the network wasn’t just `mocha` specific but could be used in any Hardhat script.
- Use `options` object in `StarknetContract` methods instead of using optional function arguments; e.g.:
- OLD: `StarknetContract.call(functionName: string, args?: StringMap, signature?: Array, wallet?: Wallet, blockNumber?: string)`
- NEW: `StarknetContract.call(functionName: string, args?: StringMap, options: CallOptions = {})`
### Upcoming changes (with v0.4.1 or later):
- Account class that allows executing invokes/calls as a Starknet account instead of having to provide the Account/Wallet as an invoke/call option.
- Utility functions to handle devnet-specific calls (for Postman, i.e. L1-L2 communication)

New `starknet-hardhat-plugin` version (v0.4.2) has been released: [Github](https://github.com/Shard-Labs/starknet-hardhat-plugin/releases/tag/v0.4.2)
- Introduce utility functions for handling L1-L2 communication (postman message exchange with Devnet):
- Introduce an `Account` class for invoking/calling contract functions through an Account. Create `Account` using utility functions:
L1-L2 communication:
```typescript
await starknet.devnet.loadL1MessagingContract(...);
const l1contract = ...;
const l2contract = ...;
await l1contract.send(...); // depending on your L1 contract interaction library
await starknet.devnet.flush();
await l2contract.invoke(...);
await starknet.devnet.flush();
```
Account interaction:
```typescript
const contractFactory = await starknet.getContractFactory("MyContract");
const contract = await contractFactory.deploy()
const account = await starknet.deployAccountFromABI("Account", "OpenZeppelin");
await account.invoke(contract, "increase_balance", { amount: 10 });
const { res } = account.call(contract, "get_balance");
```

- Introduce `--starknet-network` flag to `hardhat test` and `hardhat run`
- Properly adapt input before passing to account:
- Fixes BigNumber, Array, Struct, Tuple support (for the case of interacting through an account)
- Also exposes `StarknetContract.adaptInput` and `StarknetContract.adaptOutput`
- Use hardhat 2.9.0 as a dependency.
- Update `hardhat starknet-verify` command:
- Adapt to the new Voyager API
- Allow multi-file contracts.

- Change `deployAccountFromABI` ( **breaking** ):
- Now called `deployAccount`
- First parameter (specifying file name) not needed anymore:
- Fetching of Account files done automatically - fetches the latest account version compatible with plugin
- Fix deploying contracts with empty constructors.
- Remove `--starknet-network` CLI option from `hardhat run`:
- There are issues with overriding hardhat tasks and introducing new CLI options - however `hardhat test` keeps its `--starknet-network` option
- One might argue that this is a **breaking** change, but this feature was never available at all because v0.4.3 made deploying in hardhat scripts impossible - this is now fixed.
- Specifying the network can still be done through the `network` property of `starknet` in `hardhat.config`.
- Return tx hash on `StarknetContract.invoke`.

- Adapted to cairo-lang v0.8.1:
- If using the dockerizedVersion, you might notice improvement because the underlying docker image has been optimized since v0.8.1.
- Introduced `--disable-hint-validation` flag to the `hardhat starknet-compile` command:
- Allows compiling contracts with e.g. printing in hints (useful for debugging when deploying and executing on Devnet).
- Introduced `--token` option to the `hardhat starknet-deploy`:
- Allows whitelisted deployment on mainnet.
