Enterprise Grade
Protocol Bank is non-custodial by design. Your keys stay in your wallet. We cannot access or move your funds -- ever. Every transaction goes through automated security analysis before touching the blockchain.
Proxy backdoor detection, flash loan analysis, signature phishing prevention, and malicious approval blocking -- all before you sign.
Shamir Secret Sharing (2-of-3 threshold) for embedded wallets. PIN-derived encryption with AES-256-GCM. Server cannot reconstruct keys.
No unlimited token approvals. Every transaction authorizes only the exact amount needed, with address integrity hashing and tamper detection.

Why Onchain
Traditional payment rails were built for a different era. Protocol Bank leverages blockchain infrastructure to deliver settlement in seconds, not days.
| Method | Cost | Settlement | Cross-Border |
|---|---|---|---|
| Protocol Bank (x402) | $0 gas for sender | Instant signature | Native, 10+ chains |
| Layer 2 Transfer | $0.01 - $0.10 | ~2 seconds | Same chain only |
| Wire Transfer (SWIFT) | $25 - $50 | 1-5 business days | High fees, slow |
| Traditional Payroll | $5 - $15 per employee | 2-3 business days | Complex, regulated |
Native Stablecoin
The first stablecoin on Hashkey Chain — built for enterprises that demand privacy, compliance, and sustainable DeFi yield.
1:1 USDC Backing on Circle
Every $PUSD is minted at a 1:1 ratio with USDC on Circle, ensuring full collateralization and transparent reserve proof at all times.
CCIP-Secured Cross-Chain Redemption
Leveraging Circle's Cross-Chain Interoperability Protocol (CCIP), $PUSD guarantees stable and trustless redemption across supported networks.
FHE Privacy (Roadmap)
With the upcoming mainnet upgrade, Fully Homomorphic Encryption (FHE) will be integrated — enabling confidential on-chain transactions ideal for enterprise finance.
Institutional-Grade Staking Yield
An upcoming staking model will allow enterprises to earn stable, risk-adjusted DeFi yields on idle $PUSD holdings — without sacrificing security or liquidity.
Open-Source Smart Contracts
All $PUSD contracts are fully open-source and publicly auditable, ensuring maximum transparency and community trust.
