Simplified privacy
Semaphore streamlines privacy-centric app development. It empowers developers to effortlessly incorporate robust privacy features.
Universal integrations
Semaphore is a protocol for Web2 and Web3. It integrates into any front-end framework or pure HTML/CSS/JS. It is cross-chain compatible with EVM, L2s, and alt-blockchains.
Leverage Zero Knowledge
Semaphore leverages Zero Knowledge, allowing us to verify information without revealing any underlying data. This powerful primitive allows one to prove membership and signal anonymously.
Free open source software
Semaphore is a Public Good. This means it will never seek to profit, it is owned by the community and will always remain open source.
