Two rails. One balance sheet. Always on.
An indicative view of how Vayan is being designed to coordinate fiat and stablecoin settlement, structured compliance records, and supervisory visibility within one governed operating layer.
The Settlement Engine
Diagram: Rail A (Red) and Rail B (Green), connected by the Bridge (Blue).
Rail A - Fiat Settlement
FedNow, ACH, CHIPS, SEPA, ISO 20022. The fiat-side pathway handles all fiat-denominated settlement, including credit origination for cadastral hypothecation.
Rail B - Tokenized Settlement
Ethereum, Base, Polygon, Arbitrum, Hedera HTS, Solana. The tokenized pathway handles digital assets including tokenized real estate titles from DLD and RER.
The Vascular Bridge
Unifies Rail A and Rail B into a single balance sheet. Enables cadastral hypothecation: fiat credit against tokenized collateral with programmatic enforcement.
Multi-Agent Consensus - Settlement Governance
Vayan is being designed around consensus across independent control layers before regulated execution. The goal is structural enforcement, not procedural sign-off.
Step 1 - Proposal
The target model begins by receiving and structuring a transaction request, whether that request originates from a client instruction, an API call, or an authorised automated treasury workflow.
Step 2 - Compliance Validation
The intended compliance layer validates the proposal against the institution's policy record, the applicable legal and regulatory ruleset, and the transacting party's mandate parameters. The design goal is that regulated execution does not proceed without successful validation, and that failed validations produce a structured reason code.
Step 3 - Execution
The execution layer is intended to release an instruction only after the required settlement and policy approvals are present, with the approval chain committed to the event record before external transmission.
Human Governance
Material transactions and enhanced-scrutiny cases are intended to route to designated human officers based on mandate and policy thresholds configured with each institution. The model is not being designed for unilateral execution in those cases.
The Compliance Metadata Tag
The target operating model assigns each regulated transaction a structured compliance record containing identifiers and timestamps, initiating party and mandate references, routing context, policy-decision outputs, screening metadata, human-review flags where applicable, and an event-ledger reference.
The design intent is for this record to be committed before execution and made available to authorised operators, compliance reviewers, and supervisory parties where the regulatory relationship requires it.
The Canonical Event Ledger
The target model uses an append-only event ledger as the reconstruction layer for transaction history, policy validations, and system state changes. It is intended to serve as the primary record for account states, positions, and compliance decisions across the Vayan operating environment.
Observer Agent - Planned Supervisory Interface
The Observer Agent is being designed as a provisioned, read-only interface for authorised oversight bodies and internal control teams. The intended scope includes balance visibility, compliance-record access, reserve and reconciliation views where applicable, and system-health indicators.
This is the supervisory model Vayan is being built toward, not a statement that continuous regulatory interfaces are already live today.
Specific authorities, access scopes, and delivery methods depend on authorisation, jurisdiction, and the supervisory relationships established over time.
Cadastral Hypothecation Module
The technical infrastructure for collateralized lending against tokenized government-registered land titles. Developed for Dubai DLD and Saudi RER integration.
Registry Adapter
Interfaces with national cadastres (DLD, RER) to verify tokenized title authenticity, ownership, and encumbrance status.
Valuation Oracle
Multi-source property valuation combining government data, market comparables, and AI models. Continuous price monitoring.
Circuit Breaker Engine
Hard-coded LTV ceilings (60%), concentration limits, and appreciation caps. No manual override. Regulator-visible.
Vascular Bridge
Links Rail B collateral positions to Rail A credit origination. Unified balance sheet view across both rails.
Continuous Monitoring Loop
Real-time collateral monitoring with automated margin calls at 70% LTV and liquidation at 75%.
Observer Agent
Streams aggregate exposure, collateral health, and compliance flags to regulators in real time.
Security Architecture
The production design is intended to use HSM-managed keys for settlement instructions and ledger events, isolated execution environments for critical control components, and mutually authenticated external connections. Final controls will be documented in the security and due-diligence materials shared with qualified counterparties.
