Understanding
how money actually moves.
Payment Bridge Core is a backend-first fintech infrastructure prototype that models the systems behind digital payments — from authentication and wallets to settlement, reconciliation and multi-rail orchestration.

Core principles
Ledger-first balances
Balance comes from entries, not a floating stored value.
Rail abstraction
Mock, Stripe, and CBDC all pass through the same core flow.
Settlement
Hold, completion, and release stay balanced in the ledger.
Reconciliation
The system checks that local and remote state still agree.
