Keep is a privacy layer for Ethereum. A “keep” is an off-chain container for private data. Keeps help contracts harness the full power of the public blockchain — enabling deep interactivity with private data. The Keep network, powered by KEEP tokens, handles custodianship for tBTC.



Summa provides custom-built interoperability solutions for companies throughout the blockchain ecosystem. Its solutions allow companies to access larger markets, expand their feature-sets, and access new liquidity in a unified cross-chain marketplace.

Through educational events, advisory services, and open-source tooling, its goal is to expand blockchain interoperability and foster an environment that is more connected, functional, and scalable.
