ZK on the edge
Zero-knowledge proofs at the edge
Proofs are created and checked on device or at the edge, so you don’t need a round-trip to a central server. Works for offline payment flows and keeps latency low.
Agentic AI Payments
ZK on the edge. Offline proofs. Double-spend prevention.
Run autonomous payments with ZK proofs created and checked at the edge. Verification works offline, ZOD handles validation, and proofs are bound so double-spend is blocked. No PII, and built for machine-to-machine use.
Agentic payments. No PII stored. Offline-first.
How agentic AI payments work
An agent or device creates a proof at the edge. You verify locally or offline. The proof nonce and ledger stop double-spend; settlement runs when you’re back online.

Proofs are bound to a unique nonce. Duplicate submission is rejected. No personal data is stored at the edge or in the cloud.
Technical stack for agentic AI payments
What you need to run autonomous payments at the edge: ZK proofs, offline support, and double-spend prevention.
Double-spend prevention
Cryptographic nonce and ledger
Every proof has a unique nonce. Ledger Guardian and proof serialization catch duplicates. The same proof can’t be reused, whether you’re offline or at settlement.
ZOD & schema validation
Type-safe payloads and proofs
ZOD (and schema validation) validate payment payloads, proof shapes, and API inputs. Type-safe agentic payments with validated data before proof creation or verification at the edge.
Offline payments
Payments without connectivity
Create and verify proofs offline. When the link is back, settlement and double-spend checks run. Suited to field agents, remote terminals, and payment flows that need to keep working when connectivity drops.
Why agentic AI payments need ZK on the edge
Agents and machine-to-machine systems can approve or reject payments without a human in the loop. Edge ZK proofs and double-spend prevention keep it safe and compliant.
- No PII at the edge or in the cloud.
- Verification works offline so agents and terminals don’t depend on connectivity.
- Proof nonce and ledger checks prevent double-spend.
- ZOD and schema validation keep payment and proof data type-safe.
- PCI-DSS friendly when you don’t store cardholder data.
Agentic AI payments are flows where agents or systems make payment decisions without a human. ZK on the edge means proofs are created and verified on device or at a local server, so you get offline payments and low-latency verification. Double-spend is prevented by proof nonce serialization and Ledger Guardian; the same proof can’t be used twice. ZOD and schema validation keep payment payloads and proof shapes type-safe before proof creation or verification. AffixIO provides the API and infrastructure for agentic, offline edge, and machine-to-machine payments without storing PII. For API access, contact hello@affix-io.com or use the contact page.
Frequently asked questions
Answers on ZK at the edge, offline payments, double-spend prevention, and ZOD.
What are agentic AI payments?
Payments where agents or systems approve or reject without a human. AffixIO supports them with ZK at the edge, offline verification, and double-spend prevention.
How does ZK on the edge work for payments?
Zero-knowledge proofs are generated and verified at the edge. Proofs attest to eligibility or balance without revealing data. Verification works offline; settlement syncs when connectivity returns.
How does double-spend prevention work offline?
Every proof has a unique nonce and is tied to the transaction. Duplicates are caught locally or at settlement. Ledger Guardian makes sure the same proof can’t be used twice.
What is ZOD in the payment flow?
ZOD is a TypeScript schema library. We use it to validate payment payloads and proof shapes at the edge and in the API so agentic payments stay type-safe.
Can agentic payments work fully offline?
Yes. Proofs can be created and verified offline. The merchant or agent validates locally; settlement and double-spend checks run when the network is back.
