Horizen Documentation

Horizen is home
for privacy-first
onchain app developers.

Horizen is an EVM-native L3 on Base designed for private onchain finance and compliance-forward blockchain app development.

What is Horizen?

It adds what Base doesn't have

Privacy tooling

Compliance plug-ins

Base liquidity

Horizen adds what other EVM chains lack – a tight focus and supportive tooling for private onchain finance and regulatory-compliant blockchain application development, while retaining what other privacy blockchain projects left behind – familiar EVM architecture, composability, and developer ergonomics. No new language, no obscure tech stack.
