Why the Zetrix Agentic Wallet

Zetrix is uniquely positioned to host both protocols in one wallet:

• It already issues verifiable identity. Through ZID, Zetrix digitizes national IDs and business-registration credentials into W3C Verifiable Credentials, anchored by the BID DID method (registered in the W3C DID Specification Registry). This is exactly the issuer/credential infrastructure x401 assumes but does not itself provide.

• It already moves value. The same wallet that settles x402 payments (in native ZETRIX or JMYR, a ZTP20 token) can attach the identity proof x401 demands, one agent, one wallet, two challenge types.

• It is chain-anchored and cross-border. On-chain issuer registries and revocation lists give x401 a tamper-evident, globally reachable trust root without a central authority.

Delivery staging

This paper describes three progressive stages so readers can distinguish what is required now from what comes later:

Stage	Identity (x401)	Payment (x402)	Credential	Issuer
MVP	Yes	None (free)	Agent Credential	ZCert
POC	Yes	Subscription + usage	API Subscription Credential	Zetrix BaaS VC issuer
Future	Yes	Per-access (proof + pay)	Any required credential	Per-resource
