What zPayy does

Privacy that lives on-chain, not just in the UI

Shield public stablecoins into encrypted balances, then send, request and settle — amounts confidential on the ledger itself.

Core action

Shield & Unshield in one tap

Wrap public USDC, USDT or ZAMA into confidential balances encrypted on-chain with fully homomorphic encryption — and unwrap back to public ERC‑20 whenever you need liquidity.

Encrypted with Zama fhEVM

Confidential balances

Per-token balances stay sealed as •••• until you decrypt them with biometrics or PIN.

Batch send

Pay many recipients in one confidential flow — payroll, splits and treasury moves.

Encrypted ledger

A unified feed of sends, receives, shields and requests — with on-chain confidentiality.
