How it works
Trade engine
The trade engine is the server-side authority for app-level Tap Trades validation.
Validation
The trade engine checks identity, terms acceptance, session key status, quote freshness, market status, account balance, leverage, notional size, risk limits, and idempotency before a PaperTrade transaction is submitted.
Lifecycle
Every submitted action has a traceable lifecycle: created, signed, validated, submitted, confirmed, failed, reverted, reconciled, or settled.
