Streamlined and easy integration
The Relayer is a REST API product built by Horizen Labs. The Relayer streamlines the process of submitting and verifying proofs. Anyone can integrate their zero-knowledge application with the Relayer API, and the process is simple and straightforward. Our goal is to enable high performant tools for developers to build verifiable systems at a low cost and with ease.
Proofs are optimistically verified by the Relayer, and submitted on-chain to the ZKVerify blockchain. ZKVerify is a decentralized blockchain dedicated to zero-knowledge proof verification. Zero-knowledge proofs confirm that a computation was done correctly without revealing sensitive data involved.
The Relayer API is available on both mainnet and testnet. Try it out! Read our guide here.
