Xahau anchoring — legacy surface

This page documented an older Xahau/URITokenMint credit-scoring architecture. It is retained only for historical continuity and is not a current payment, trust, or buyer authority.

Current public payment authority: x402 v2 · Base mainnet eip155:8453 · USDC. Callers inspect the fresh payment challenge and control their own spending policy.

Current trust product: Provider Trust for provider identity, reliability, payment and accepted-delivery evidence.
