The Three Architecture Pillars
Depa separates the complexities of modern multi-asset financial operations into three distinct, deterministic layers:
The Watch
Pre-Execution Risk & ComplianceSanctions screening, KYC/KYB identity checks, AML velocity limits, and Four-Eyes dual approvals.
The Journal
Multi-Rail ExecutionDirect clearing for SEPA Instant, SWIFT, Open Banking, card payments, and blockchain stablecoin rails.
The Book
General Ledger of RecordImmutable multi-asset accounting, continuous bank and RPC reconciliation, statements, and audit reports.
The Book
The immutable, multi-asset general ledger of record. Holds balanced accounts across fiat, stables, and digital assets.
The Journal
Where rails become ledger entries. Executes SEPA, SWIFT, cards, and stablecoin transactions across 23 currencies.
The Watch
One brain across every rail. Pre-execution compliance, transaction monitoring, sanctions screening, and governance.
