Overview

What is Stealth Pay?

Stealth Pay is a zero-knowledge privacy protocol for ERC-20 tokens on 0G Chain. It lets users shield tokens into an on-chain pool, transact privately inside it, and withdraw to any address — with no observable link between deposit and withdrawal.

Every operation is backed by an UltraHonk ZK proof verified by an immutable smart contract. There are no relayers, no trusted parties, and no off-chain state. Privacy is a protocol guarantee, not a policy.
