Konto

An open-source, production-grade double-entry ledger engine engineered for modern fintech infrastructure. Konto enforces strict zero-sum conservation via deferred PostgreSQL constraint triggers and eliminates deadlocks by lexicographically sorting account IDs before issuing FOR UPDATE locks. Shipped with a Prisma-pattern DX generator and O(1) balance reads via LATERAL JOIN checkpoints, it provides a mathematically rigorous, transactional primitive capable of safely processing high-volume escrow queues and autonomous agent finance pipelines.
