Two roles. Neither is an exchange.
CrossDesk is the price layer for tokenised funds on the Canton Network: it administers the fixings those funds settle against, and it is the transfer agent through which their shares are created and redeemed at the attested number.
An administrator, and a transfer agent.
Benchmark administrator
For tokenised assets on Canton that no administrator covers — wrapped assets, baskets, funds whose underlying market is closed. CrossDesk proposes the fixing at a declared time, has a K-of-N committee of parties with money on the mark attest it, and publishes it with its tier, its signers and the conditions each signer verified. Products: CBTC Close, cETH Close, and fund NAVs such as LX1.
Transfer agent
For funds that reference those fixings: creation and redemption in kind, at the attested NAV, atomically, for authorised participants. Deliver the basket, receive shares — or the reverse — all-or-nothing, with the fee charged in the same transaction. The mechanism that keeps a fund glued to its NAV.
The whole system is a set of Daml packages on Canton, a Spring backend that operates them, and the desk. On Canton a contract is visible only to its signatories, so a sealed order is observed by nobody and a fixing's signatory set is its attestor set — properties the design relies on rather than adds. A sealed closing auction exists as a module for assets with a real market on Canton; it is not on the pilot surface.
Stated plainly, because the distinctions matter.
Not an exchange
CrossDesk does not operate a continuous market and does not earn trading fees. A continuous book and a perpetuals layer exist in the code, tested, and neither is sold: operating a market is a licensed activity, and staying out of it is deliberate.
Not a custodian
CrossDesk holds nobody's assets. Creation and redemption move holdings between the authorised participant and the fund on the ledger; nothing passes through the administrator.
Not a regulated administrator
Benchmark administration is a licensed activity in the UK and EU. CrossDesk is not authorised, registered or recognised anywhere, and says so on its Regulatory page.
Not a price feed
A feed relays a number that exists. CrossDesk attests a value where none exists to relay — a wrapper's discount to par, a basket, a fund at 03:00 on a Sunday — under a published method, with every signature attributable.
Not a trader in what it prices
The administrator does not take positions in the instruments it fixes. That is a hard constraint on the business, not a preference.
Not live on a network participant
The hosted desk is a sandbox: an in-process Canton ledger running the real packages with a demonstration book. It proves the software, not the network integration. A DevNet participant is the standing blocker.
Built by one person, so far.
CrossDesk was built for HackCanton Season 2, where it won Best Financial Application on 5 August 2026, and has been developed since into the administrator-and-transfer-agent shape described on this site. Source-available, not open source — read the code.
