Practical overview

When it fits

Use it when you want to configure and coordinate wallet operations through a Python CLI and the required module and network integrations are listed by the project.

  • Users seeking documented bridge, swap, lending, NFT or approval modules for the tool's listed integrations.

Documented uses

Before you choose

Requirements & limits

The project is distributed as a public GitHub repository with a documented git clone setup.

  • It requires local configuration of private keys, module settings and RPC endpoints.
  • HTTP/S proxy configuration is supported; the README says one proxy is assigned per account and that fewer proxies than accounts limits how many accounts run.
  • The README lists referral codes enabled for Odos, XY.Finance, OpenOcean and 1inch and says they can be turned off in config.py.
  • The README marks L2Telegraph NFT bridging and messaging as Arbitrum Nova-only.
  • Documentation names selected integrations and does not demonstrate support for arbitrary EVM networks.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up the CLI from its repository

Prepare the documented Python application and configure its required wallet and module inputs.

Before you start

  • Python environment capable of installing the repository's requirements
  • Private keys for entries in accounts.txt
  • RPC settings in zksync/data/rpc.json

Steps

  1. Clone https://github.com/czbag/zksync.git and change into the zksync directory.

  2. Install dependencies with pip install -r requirements.txt.

  3. Configure required modules in modules_settings.py and settings in settings.py.

  4. Place account private keys in accounts.txt and configure the RPC file at zksync/data/rpc.json.

  5. Start the program with python main.py.

Expected outcome

The documented setup sequence installs the CLI, applies configuration and starts main.py.

Guide limitations

  • Network transactions require configured accounts, RPC settings and applicable integrated services.
