UK Financial Ltd Confirms Exchange-Level Execution and Acceptance of the World’s First ERC-3643 Exchange-Traded Security Token (SMCAT) on CATEX Exchange

UK Financial Ltd today announced the successful exchange-level execution and acceptance of MayaCat Regulated Security Token (SMCAT), the world’s first exchange-traded security token built on the ERC-3643 regulated asset standard, now live within the CATEX Exchange environment.

This announcement confirms completion of Part One of a deliberately phased deployment process: compliant issuance, exchange integration, and verified ERC-3643 transfer execution under enforced identity and compliance controls. Live market trading of SMCAT is scheduled to commence Monday, following final exchange activation procedures.

A First-of-Its-Kind Exchange Execution

SMCAT is a fully permissioned, compliance-native exchange-traded security token designed from inception to embed regulatory controls directly into the asset itself. Built using the ERC-3643 framework, SMCAT enforces identity verification, jurisdictional restrictions, and rule-based transfer logic at the protocol level, without reliance on off-chain workarounds.

As part of exchange-level validation, UK Financial Ltd successfully executed and confirmed compliant token transfers within the CATEX environment, demonstrating that ERC-3643-based securities can operate under real exchange conditions with enforced restrictions and auditable outcomes.

Supply Restructuring and Ownership Impact

SMCAT represents the regulated successor to the original MayaCat (MCAT) structure. The original MayaCat system carried a total issued and outstanding supply of 2,000,000,000 units. The successor instrument, SMCAT, was issued with a fixed supply of 50,000,000 units, representing an approximate 88.5% reduction in total supply.

As a result of this restructuring, existing MayaCat holders experienced a material increase in proportional ownership, estimated at approximately a 4,000% increase on a per-holder basis, subject to compliance eligibility and phased distribution procedures.

Execution of this transition has been intentionally broken into stages, with Part One confirming exchange acceptance and system functionality, and subsequent phases addressing holder allocation as compliance conditions permit.

Verified On-Chain Infrastructure

SMCAT operates through a fully verified, multi-contract ERC-3643 architecture, with all core components publicly available on Etherscan:

SMCAT Token Contract (ERC-3643):

https://etherscan.io/token/0x4198fa66779c1ee49c10adfb378fa1d5e3314d5c

Compliance Contract:

Identity Registry Contract:

https://etherscan.io/address/0x46e4a2327b0a851acd824a268744da44342fe842

These contracts collectively enforce identity-based ownership, permissioned transfers, and compliance-gated participation directly on-chain.

Market Significance

Regulated digital securities have historically faced structural barriers to live exchange deployment. The successful execution and acceptance of SMCAT demonstrates that a compliance-native, ERC-3643 exchange-traded security token can function within a live exchange environment, with enforced controls, transparency, and audit-ready transaction logic.

By separating technical execution from trading activation, UK Financial Ltd follows standard practice for regulated financial instruments entering active markets.
