Payments

Every payment today exposes an account number.

Cards leak every transaction. Wire fraud runs on missing approvals. Crypto wallets rely on a phrase you either wrote down somewhere or forgot. The whole payment stack was designed for a world where identity was cheap and revocation was impossible.

What is itSelf-custody wallet plus cryptographic payment authorization. Every payment ships with a signed authority chain: authority · policy · evidence · preconditions → decision hash.

Why it mattersWire fraud is the largest single B2B payment loss category. It runs on missing approvals and signatures that don't cryptographically bind to the amount + recipient.

When to useFor payment authorization workflows (wire, vendor, board), for self-custody wallets without seed phrases, or for cross-border settlement with signed authority audit.

How it differsThe wallet appears on first login with no seed phrase. Every payment carries an exportable signed authority chain that downstream systems can verify without querying H33.

Evidence/v1/pay, /v1/wallet/init, /v1/wallet/balance production-live today. Payment authorization signed and replayable. Cross-border on Solana.
