One equity market

Accessible in closed pilot.

A share on one book, its cash on another, its clearer and depository on a third. Tokenized, it now trades on venues and ledgers its depository does not run. The protocol settles between them as they are.

Clients keep venue, custodian and positions

You keep your book, clients and rules

The protocol takes no control or custody

Reach is bought with copies and pre-funding,
and never called reach.

Copies of holdings, outside of your book

A copy is minted so the holding can settle against cash on another ledger, and it is your name on the question of who holds what.

Cash positioned ahead of the trade

Cash lands on the asset's venue before anything is agreed, every venue and every currency. Tokenization has rebuilt the nostro account.

External product demand cannot be met

Offering something issued on another venue means joining it, or asking its holders to join you. Both happen before the first trade.

And that is the simple case: one share, one payment.

A portfolio transition, a basket against cash, a delivery with a hedge attached. In Europe a trade clears at one of twelve houses, and where two of them interoperate a member posts margin twice. Trades that would touch three books are mostly not attempted at all.

All legs commit
where they live.

The protocol coordinates every leg where it already sits, all released together or none at all. Neither side is left holding the other's value alone.

Across venues, clearers and depositories, cleared or bilateral, net or gross. The EU, the UK and Switzerland move to T+1 on 11 October 2027, and the SEC has approved tokenized shares trading in the US on the same order book as the shares they represent.

/01

One asset, not a copy of one

No wrapped versions on books you do not control. A holding is the same holding wherever it is recorded, so it is worth the same everywhere.

/02

Split balances become captured flow

A leg no longer has to stand on the same book as the leg it settles against, so what was positioned against every venue comes back.

/03

Service market-wide product demand

Anything issued on a connected book is something your clients hold through you. What they can own stops being decided by where it was issued.
