Infrastructure

Six engines. One account.

Every feature in the app is powered by a dedicated backend platform built by Transaction Science. No third-party stitching. One architecture end to end.

Why this matters

One trade. Six systems. Zero seams.

When you buy a stock, TradingOS matches and settles the order. ComplianceOS screens the transaction and generates evidence. Veritas computes the tax lot and tracks cost basis. LegalOS confirms jurisdiction and regulatory requirements. Insights meters the cost and carbon. All of it happens in a single request cycle. No webhooks. No batch jobs. No reconciliation.

How a trade actually moves

One trade. Two architectures.

Follow a single order — buy ten shares — through a stack stitched from separate companies, and through Settlement. The difference isn't the feature list. It's whether the parts were built to fit.

The stitched stack
Five companies. Five ledgers. Handoffs in between.
Order: BUY 10 shares
Broker-dealer Ledger 1
Takes the order
↓ FIX drop → overnight file
Clearing firm Ledger 2
Clears & holds the position
↓ ACH batch + reconciliation file
Sponsor bank Ledger 3
Moves the cash leg
↓ End-of-day API export
Tax engine Ledger 4
Computes the lot, later
↓ Webhook, eventually
Crypto venue Ledger 5
If the order touched crypto
Settles T+1–T+2 · 4 ledgers reconciled overnight · breaks → operations queue
Settlement
One platform family. One ledger. One request cycle.
Order: BUY 10 shares
TradingOS
ComplianceOS
Veritas
LegalOS
Insights
TerraOS
↓ same request
Settled · one ledger · nothing to reconcile · confirmation issued

TradingOS matches and settles. ComplianceOS screens and files evidence. Veritas books the lot. LegalOS confirms jurisdiction. Insights meters cost and carbon. TerraOS handles any real-asset leg. All in the cycle that started when you tapped buy.

Same trade. A stitched stack reconciles; a built stack just settles.
