Money moves correctly. Every time. Under any load.
LedgerX is a financial transaction engine built around one guarantee: no race condition, retry, or system failure will ever corrupt a balance or duplicate a transfer.
Core Guarantees
ACID Compliance Under Concurrent Load
Pessimistic row-level locking with deterministic acquisition order prevents deadlocks. Every transfer either commits fully or rolls back completely - no partial states, no phantom reads.
Idempotent API Design
Every transfer requires an Idempotency-Key. Duplicate network retries return the cached result. In-flight duplicates are rejected with a 409. Double-charging is architecturally impossible.
Immutable Double-Entry Accounting
Every successful transfer generates exactly two ledger entries - one debit, one credit - bound to a parent transaction record. Balances can be reconstructed deterministically at any point in time.
