Raycash launches confidential stablecoin payments and private yield on Ethereum

confidential stablecoin payments — Raycash, a spin-off from cryptography firm Zama, has launched its application on the Ethereum mainnet, enabling private stablecoin transactions and confidential yield generation.

The platform allows users to make payments in stablecoins like USDC and USDT with enhanced privacy, shielding transaction amounts and counterparties from public view on the blockchain. Raycash integrates with the Morpho decentralized lending protocol to generate yield on idle stablecoin balances, with the yield accrual process also kept confidential.

The service leverages Zama’s fully homomorphic encryption (FHE) technology, which allows computations on encrypted data without needing to decrypt it first. This approach aims to provide financial privacy while maintaining compatibility with existing Ethereum wallets and decentralized finance infrastructure.

The launch represents a growing trend of privacy-enhancing applications entering the DeFi ecosystem, seeking to address transparency concerns that can lead to front-running and wallet profiling. Raycash’s model focuses on transactional privacy for stablecoins, a core component of the digital economy.
