The SQL Problem

Why standard databases fail at scale.

Race Conditions

UPDATE credits = credits - 1 leads to negative balances when two requests hit simultaneously.

Audit Nightmares

Standard updates overwrite previous state. You lose the history of "who, when, and why" a balance changed.

Latency Locks

Row-level locking in Postgres slows down your entire application during peak traffic events.

Built for Mission-Critical Systems

The infrastructure layer you can trust with real money.

High Throughput

Capable of handling 10,000+ financial transactions per second per region.

99.999% Uptime

Distributed multi-region architecture ensures your ledger never goes down.

Idempotency

Safe retries. We guarantee that a transaction is processed exactly once.
