cuiledger.com & .eth | CUI Unified Ledger Identity

cuiledger is where the SEC’s Covered User Interface framework meets the global institutional ledger architecture. As central banks, the BIS, and the OCC converge on the Unified Ledger concept as the foundation for next-generation financial infrastructure, cuiledger.com & .eth provides the Convergence Identity that bridges both worlds.

A core component of the CUI Compliance Infrastructure, cuiledger connects the regulatory clarity of the SEC CUI framework with the architectural vision of the BIS Unified Ledger — in a single, institutional-grade Twin-Domain identity. As the institutional Covered User Interface Ledger identity, cuiledger.com & .eth bridges the SEC’s CUI framework with the BIS Unified Ledger architecture — the global reference standard for tokenized deposits and atomic settlement.

The CUI Regulatory Convergence — SEC, OCC, and BIS Unified Ledger Standards

The SEC Staff Statement on Broker-Dealer Registration of Covered User Interfaces of April 13, 2026 establishes the CUI as the compliant interface layer for blockchain-based financial transactions. The OCC’s 376-page Proposed Rule simultaneously requires permitted payment stablecoin issuers to maintain distributed ledger infrastructure that meets Operational Resilience and Continuity of Operations standards.

The BIS — through Project Agorá, uniting seven central banks and 40+ regulated financial institutions — has established the Unified Ledger as the global reference architecture for tokenized deposits and atomic cross-border settlement. cuiledger sits precisely at the intersection of these three regulatory and architectural frameworks. With the CLARITY Act Senate floor vote imminent, the CUI ledger layer is on a direct path to statutory recognition as a core component of US digital asset market structure. The DLT interoperability standard anchoring the cross-network architecture within which CUI ledgers must operate is documented at dltinterop.com & .eth.

How the CUI Ledger Layer Resolves the Interface-to-Ledger Architecture Question

Every institution building CUI-based infrastructure faces a fundamental architectural question: where does the interface end and the ledger begin? cuiledger.com is the institutional answer — the API portal, the compliance identity, and the brand for the layer that connects a Covered User Interface to the underlying distributed ledger.

cuiledger.eth is the on-chain endpoint — ENS-resolvable, smart-contract ready, and directly addressable within the Unified Ledger architecture. Under the GENIUS Act, Permitted Payment Stablecoin Issuers must maintain cryptographically secured ledger infrastructure with full audit capability — the CUI ledger layer is the interface through which institutions access, query, and document this infrastructure. The MCI unified ledger identity addressing the parallel BIS Multifunction Cryptoasset Intermediary data availability framework is documented at mciledger.com & .eth.

The CUI Ledger Ecosystem — From Settlement and Repo to Privacy-Preserving Verification

cuiledger is the architectural backbone of the CUI Compliance Infrastructure. It connects upward to cuisettle.com & .eth and cuirepo.com & .eth — both of which require a ledger layer for transaction finality and audit documentation — and to cuiintent.com & .eth where intent attestations are stored as immutable ledger records.

Beyond the CUI cluster, the CUI ledger layer integrates with repoledger.com & .eth as the repo-specific ledger identity, fheledger.com & .eth as the privacy-preserving ledger layer using Fully Homomorphic Encryption, verifiableledger.com & .eth as the ZK-proof based ledger verification standard, and rlnledger.com & .eth as the RLN shared ledger infrastructure within the BIS Unified Ledger framework. An institution acquiring cuiledger.com & .eth secures the namespace for the architectural layer that connects every CUI transaction to the permanent, auditable record of the Unified Ledger.
