Building on Canton Network

Isolated-market lending, engineered for Canton.

Every market is a contract of its own — one collateral, one loan asset, one oracle. Native atomic settlement. Position privacy by default. Built for institutions.

§ 01 Design principles
01

Position privacy

Positions are visible only to the borrower and authorized observers. Canton's selective-disclosure model enforces this at the protocol layer, not by convention. Meridiant never publishes borrower identity or position size to the network.

02

Isolated markets

Each market carries its own collateral, loan asset, oracle, and interest-rate curve. A bad-debt event in one market cannot cascade into another. No pooled risk. No cross-collateralization surprises.

03

Atomic composition

Borrow, swap, and deploy in a single Canton transaction. If any leg fails, the entire transaction reverts — across Canton participants and applications, not just within Meridiant.

04

Selective disclosure

Auditors, regulators, and counterparties see exactly what they need to see — and nothing else. Observer sets are configured at market issuance and cryptographically enforced.

§ 02 Market anatomy

A Meridiant market is a Daml contract. Four parameters define it — collateral, loan asset, oracle, and interest model. Everything else is derived. Everything else is isolated.

§ 03 Why Canton

Credit rails, not a casino floor.

Canton is the settlement layer for over $6 trillion in tokenized assets and $280 billion in daily repo. It ships privacy, atomicity, and sub-second finality out of the box. Meridiant is designed to inherit all three.

§ 03·A

Sub-second finality

< 1s

Canton commits transactions in under a second — the latency profile institutional credit desks expect from tri-party repo settlement, not the multi-block finality of general-purpose L1s.

§ 03·B

Institutional participants

45+ SVs

DTCC, Goldman Sachs, JPMorgan Kinexys, Visa, Tradeweb, Cumberland, and dozens more. Markets can require KYB'd counterparties by default — a first-class primitive, not a bolt-on.

§ 03·C

Native privacy

Need-to-know

Data is replicated only to parties permissioned to see it. Position sizes, collateral, and rates are not public state. Regulators see what they need; competitors see nothing.

§ 03·D

Atomic across apps

Global Sync

Canton's Global Synchronizer allows atomic composition across independent applications. Repo desks, DEXes, and Meridiant markets settle in a single transaction — or none of them do.
