How CertaCota Works
The six primitives that make concurrent token economies possible — and what each one means for your platform.
Balances That Move in Real Time
Most billing systems record money movement when an event happens. CertaCota also records it as time passes — draining a balance continuously at a configured rate so a per-minute session or a per-second GPU job settles at exact duration, not a rounded approximation. This is a native primitive, not a workaround layered on top of a discrete ledger.
No Conflict Between Streaming and Instant Charges
When a per-minute charge and a one-time payment hit the same account simultaneously, one will see a stale balance if the ledger isn't built for it. CertaCota serializes both against a single live balance in strict order — the discrete charge sees the balance as it stands at the exact moment it arrives, accounting for the accumulated streaming drain up to that instant. There is no overdraft window, no optimistic locking, and no application-level retry logic required.
Know When the Balance Runs Out — Before It Does
CertaCota exposes a forward estimation endpoint that computes projected time-to-zero from the current balance and active streaming rate — no polling, no stale snapshots. Build a live countdown showing minutes remaining in a billing session, a low-balance alert that fires before the account runs out, or an API credits dashboard showing a developer exactly when their active job will exhaust their credits. The estimation derives from the engine's internal session state and updates continuously.
Correlate Any Set of Transactions by Tag
Every transaction — streaming charge, one-time payment, or fee settlement — can carry a session tag. Query CertaCota by tag to get the complete session ledger: total charges, rake applied, net payout — no separate aggregation layer required. The engine stores and queries by tag; session lifecycle and participant orchestration live in your platform.
Every Fee Lands Atomically
CertaCota implements rake as a first-class primitive: platform fee, operator cut, and net payout are split in a single atomic operation with no intermediate state. Split ratios are configured at the session or transaction level, not hardcoded. If the settlement fails, no partial split occurs — the session remains open and can be retried.
React to Settlement Without Polling
Every balance movement produces an event the moment it occurs — session started, threshold crossed, settlement complete — delivered to your platform without polling. Downstream systems respond to outcomes rather than querying for them: subscribe to settlement events for fraud detection, act on low-balance thresholds before a session ends, or trigger top-up prompts automatically. The enterprise tier extends delivery to Kafka, AWS SQS, and RabbitMQ for high-throughput pipelines.

Capabilities assessed based on publicly available documentation as of 2026.
¹ Modern Treasury: Webhook-based notifications for discrete transaction state changes only; no event stream for continuous rate-based balance movement.
² Blnk Finance: Webhook-based notifications for discrete transaction state changes only; no continuous event stream.
³ Standard billing tools (e.g., Stripe Billing): Webhook events for discrete payment state changes; no event emission from continuous balance drain because no such primitive exists.
