Raycash is a team currently incubated inside of Zama. We are reimagining digital money for the real economy, combining the privacy of banking with the openness of blockchain. Powered by Zama’s Fully Homomorphic Encryption (FHE), Raycash enables confidential on-chain transactions without compromising compliance or decentralisation.
Our mission is to bring financial privacy to the internet age. By wrapping fiat-backed stablecoins such as USDC and USDT into encrypted, one-to-one confidential tokens, Raycash allows users and businesses to transact privately, with balances and amounts visible only to authorised parties.
We’re now taking this technology mainstream with the Raycash app — everything you expect from a modern banking experience: IBANs, cards and privacy, but rebuilt on-chain with private digital dollars so you remain fully in control of your money. No banks. No middlemen. Just you.
Say goodbye to frozen funds, slow transfers and needless fees. Raycash gives you the control of crypto, the privacy of banking and the simplicity of everyday money.
