Imagine a payment messaging solution so elegant and secure it needs no database—where the payment is mathematically bound to the ISO Message, making them inseparable.
Payment Rail + Message Rail + Hook Enforcement
One Signature. 3-5s Finality.
ZPK is an open protocol SDK for payment privacy. The engine remains ours.
Your app calls the AIFS API. The engine handles the rest. The ShatterEngine never leaves the server.
Your payload is dispersed into 1,024 entropic particles. The sender's wallet address is the XOR identity salt -- no separate key management required.
A 24-character DNA cryptographic witness is generated from the particle set. This is the only artifact that travels on-ledger.
The anchor is submitted to Xahau with an XAH payment. The ZPK-Enforcer Hook validates the anchor format and enforces single-use replay protection.
The authorized party presents their wallet address and DNA anchor. The engine verifies identity and returns the original payload. No one else can.
Shatter a payload, get a DNA anchor, submit it to Xahau with the ZPK-Enforcer Hook installed on your receiving address. That is the full integration.
Full SDK reference →Your integration uses the open API. The ShatterEngine that produces the DNA anchor never leaves the AIFS server.
No encryption keys to manage. No persistent identity linkage. The sender's wallet address is the cryptographic salt -- identity is bound to the math, not stored anywhere.
The ZPK-Enforcer Hook on Xahau validates every anchor format and enforces single-use replay protection at the ledger layer. Fabricated anchors are rejected before settlement.
ZPK was designed around ISO 20022 financial messaging. Shatter a pacs.008 credit transfer, settle on Xahau, and deliver a formatted message receipt -- all in a single flow.
The ZPK protocol defines the interface, not the implementation. Any platform -- TipBots, payment apps, compliance tools -- can integrate via the API without touching the engine.
Every DNA anchor is single-use. The Hook writes the anchor to Xahau state on first settlement and rejects any duplicate submission. No double-settlement is possible.
ZPK Protocol is covered by pending US patent applications. The DNA anchor, engine signature, and Hook enforcement mechanism are protected IP of AIFS Protocol Inc.
The ZPK-Enforcer Hook is live on Xahau Mainnet. Install it from the public hook hash on any Xahau address using the Hooks Builder. Once installed, that address only accepts payments carrying a valid ZPK DNA anchor.
