Raycash is building a self-custodial global money account that allows users to hold, send, and spend stablecoins privately and compliantly, without relying on traditional banks or public blockchains. It aims to provide a Revolut-style banking experience, complete with IBANs, cards, on/off-ramps, and yield, all rebuilt on-chain and fully self-custodial. The platform ensures confidentiality of balances and transaction amounts using Zama's Fully Homomorphic Encryption (FHE), keeping user activity encrypted end-to-end and post-quantum secure, while providing necessary regulatory visibility. Users deposit stablecoins like USDC and USDT, which are then processed and wrapped into confidential stablecoins, enabling private financial transactions.
