First ERC-3643 Security Token Reaches Live Exchange Execution
UK Financial Ltd said that the world’s first ERC-3643 security token was successfully exchanged around the world. The MayaCat regulated instrument is now available on the CATEX Exchange, where it must follow strict compliance controls. This milestone means that compliant issuance, integration, and verified transfers are all done in a regulated trading environment.
The execution proves that the rules for identity, jurisdiction, and transfer are being followed at the protocol level without any off-chain workarounds. It shows that compliance native security tokens can work reliably inside real exchange infrastructures. This accomplishment sets a basic standard for trading regulated digital securities.

Phased Deployment Confirms Regulated Issuance and Integration
The announcement confirms that the first phase of a planned deployment strategy is over. This part was all about compliant issuance, integrating exchanges, and making sure that ERC-3643 transfers went through. Identity verification and regulatory controls were in place for every step.
After the final exchange is up and running, trading of the SMCAT token on the live market will begin. In later phases, we will talk about wider distribution and holder allocation while still meeting compliance requirements. This planned rollout puts regulatory certainty and operational stability first.
SMCAT Embeds Compliance Directly At Protocol Level
SMCAT is a fully permissioned security token that was made to include regulatory controls from the start. The ERC-3643 framework directly enforces identity checks, rules about where things can be transferred, and rules about where things can be transferred. This design does away with the need for outside compliance layers or manual enforcement processes.
Protocol level compliance makes sure that every transaction is by default auditable and follows the rules. Exchanges can run the asset without making big changes to the way regulations work now. This model makes sure that digital securities follow the same rules as traditional markets.

Exchange Validation Proves Real World Regulated Trading Viability
UK Financial was able to make compliant token transfers work in the CATEX Exchange environment. These transfers showed that ERC-3643 securities work like they would on a real exchange, with rules that must be followed. We were able to get auditable results without affecting how well trading worked or how well it performed.
This validation shows that regulated tokens can grow beyond pilot programs or private placements. It helps exchanges that want to list compliant digital assets use it more widely. The result makes regulators, issuers, and institutional participants more sure of themselves.
Supply Restructuring Reshapes MayaCat Ownership Model
SMCAT replaces the original MayaCat structure with a regulated process for moving supplies. Before changing to a fixed 50 million supply, the original system gave out 2 billion units. This means that the total number of outstanding units has gone down by about 88.5%.
The restructuring significantly raises the proportional ownership of eligible existing holders. Estimated per holder ownership went up by about 4,000%, but only if certain conditions were met. Distribution will happen in stages that follow the rules of the exchange and the law.
Ownership Change Done Through A Staged Compliance Process
The supply transition is being done in several controlled stages on purpose. Part 1 confirms that the exchange is acceptable and follows the rules of ERC-3643. Later phases will deal with holder allocations once the verification steps are finished.
This staged approach lowers operational risk while keeping the rules clear throughout the migration process. It makes sure that all participants meet the requirements for jurisdiction and identity before they get their allocations. The process shows how institutional-grade governance works with digital securities.
Token Launch Signals Evolution Of Regulated Digital Markets
The launch of the SMCAT is a big step forward for regulated on-chain capital markets. It shows that security tokens can meet the standards of exchanges without losing their ability to be programmed or follow the rules. This new development connects the expectations of traditional finance with blockchain-based infrastructure.
As regulated exchanges start using token standards that follow the rules, more people can join the market. Institutional investors have clearer ways to get exposure to digital securities. The launch makes ERC-3643 a useful base for future regulated tokenized assets.
