Hamsa (formerly HamsaPay) is a San Francisco-based financial infrastructure company "powering the Finternet." It builds the Hamsa Unified Confidential Ledger (UCL), a privacy-enabled, EVM-compatible, permissioned Layer-2 blockchain for banks and financial institutions, plus the Hamsa Privacy module that uses zero-knowledge-proof (ZKP) rollups on Hyperledger Besu to run confidential Delivery-versus-Payment (DvP) and Payment-versus-Payment (PvP) settlement, tokenized deposits, stablecoins, and CBDCs. The developer platform exposes an EVM-standard JSON-RPC API (eth_* methods) and DvP escrow smart contracts, authenticated with Ethereum message signatures and role-based access control. Hamsa has tokenized over $3.2B for Tier-1/Tier-2 banks (including Banco Safra's Safra Dolar stablecoin) and participates in the Brazilian Drex CBDC pilot.
