**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 zkSync smart contracts.

## Security

zkSync strictly inherits the security assumptions of L1 [here](https://zksync.io/faq/security.html).

## Changelog

The changelog of the contracts is avaliable [here](/changelog/contracts.md).

What are git dependencies?

Git dependency

Contains a dependency which resolves to a GitHub URL. Dependencies fetched from GitHub specifiers are not immutable can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are GitHub dependencies?

What are high entropy strings?

High entropy strings

Contains unicode homoglyphs which can be used in supply chain confusion attacks.

What are unicode homoglyphs?

Unicode homoglyphs

Contains a dependency which resolves to a remote HTTP URL which could be used to inject untrusted code and reduce overall package reliability.

What are http dependencies?

HTTP dependency

Install scripts are run when the package is installed. The majority of malware in npm is hidden in install scripts.

What is an install script?

Install scripts

Package has an invalid manifest file and can cause installation problems if you try to use it.

What is an invalid manifest file?

Invalid manifest file

Source files contain invisible characters. This could indicate source obfuscation or a supply chain attack.

What are invisible characters?
