# What is ZKGate? ZKGate is a **Layer-2 privacy-first blockchain** built around the concept of **ZK Pools** — pooled privacy domains that enable private transactions, pooled liquidity, and cross-chain private settlement for any project. Instead of building their own privacy infrastructure, projects integrate directly into ZKGate through an SDK, enabling: * Private swaps * Private transfers * Private staking & lending * Private fundraising * Private liquidity routing * Private payroll * Private gaming & NFT actions Web3 projects plug into a **shared but isolated privacy infrastructure**, reducing cost and complexity by over **90%**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
