# JavaScript SDK for zkSync

**zkSync** is a scaling and privacy engine for Ethereum. Its current functionality scope includes low gas transfers of
ETH and ERC20 tokens in the Ethereum network.

This document is a description of the JS library that can be used to interact with zkSync.

## Usage

Full reference on how to use the library can be found [here](https://zksync.io/api/sdk/js/).

## Changelog

The changelog of the zksync.js is avaliable
[here](https://github.com/matter-labs/zksync/blob/master/changelog/js-sdk.md).

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
