Where size settles.

Institutional OTC trading, onchain.

Trade large blocks privately and settle atomically, directly between institutional counterparties. No public order book. No custody. No intermediary.

Midpoint execution and RFQ, settled on Canton Network.

The Problem

Large trades weren't built for public markets.

Institutions moving size have had two options, and both come with a cost.

Public markets

Your order is visible to the whole market. Size moves the price against you before you finish filling, and every trade leaves a public footprint.

Traditional OTC

A dealer sits between you and your counterparty. Assets pass through hands you do not control, and settlement is a promise rather than a guarantee.

Clavius gives institutions a third option.

Private discovery. Direct counterparties. Atomic settlement.

The Venue

Everything you need to trade size. Nothing you don't.

Private by design

Your trading intent is shared only with the counterparties and liquidity tiers you choose. No public order book. No information leakage.

Non-custodial

You trade directly with your counterparty, from accounts you control. Clavius never takes custody of your assets.

Atomic settlement

Asset, payment and fees settle together in one indivisible transaction. Either everything settles, or nothing does.

The Measure

The advantages of OTC, without the trade-offs.

Clavius combines the privacy of OTC with the settlement guarantees of onchain markets.

Execution

Two ways to trade. One way to settle.

Execute at the midpoint of an independent reference price, or request firm quotes from the liquidity providers you select. Both routes are private, and both end in the same atomic settlement.

Settlement

Either everything settles, or nothing does.

Every trade takes the same path: discover, execute, settle. One atomic transaction on Canton, directly between accounts the parties themselves own.

  1. 01

    Discover

    Choose your counterparties by liquidity tier and share your intent with them alone. Nothing is shown to the wider market.

    No information leakage: your order never touches a public book.

  2. 02

    Execute

    Trade directly with the counterparty that fills you, at the midpoint or at the quote you accepted.

    No intermediary: Clavius never sits in the middle of your trade.

  3. 03

    Settle

    One atomic transaction on Canton moves the asset, the payment and the fees together.

    No settlement risk: all legs move, or none do.

Fig. V. Discover, execute, settle; one construction.

Base, quote and fee move in one indivisible step, with no half-settled state. Settlement is built to the CIP-56 standard for Canton-native assets: finality on chain, custody untouched.

Base

The asset leaves the seller's own allocation.

Quote

Payment, net of fee, leaves the buyer's.

Fee

Settles in the same indivisible step. All three legs, or none.

Mandates

Built for institutions trading size.

Rotate

Treasury teams

Rotate large positions without exposing your order to a public market.

Fill

OTC desks

Execute large client orders against institutional liquidity without taking on custody or settlement risk.

Quote

Market makers

Provide liquidity to institutional counterparties without holding client assets.

Allocate

Funds and institutional investors

Execute block trades privately, with deterministic settlement and a complete audit trail.

Four mandates, one venue, every trade settled atomically on Canton.

The Network

Built natively on Canton.

Clavius turns Canton into institutional trading infrastructure. Canton Network is the privacy-enabled public chain built for regulated financial institutions, and it is what makes this market structure possible.

Privacy at the protocol level

Transactions are visible only to their participants. Your trades exist onchain, seen by you and your counterparty alone.

Institutional permissions

Every participant completes KYB and sanctions screening before any workflow opens; availability varies by jurisdiction.

Atomic settlement

All legs of a trade move in one indivisible step, with finality on chain. Built to the CIP-56 standard for Canton-native assets.

Verified market data

Midpoint execution strikes against cryptographically signed Chainlink Data Streams, so the reference price is provable, not quoted.

The Model

Clavius is infrastructure, not a dealer.

Clavius does not take the other side of your trade, hold your assets or move funds on your behalf.

You trade directly with your counterparty. Clavius provides the discovery, execution and settlement infrastructure.

Direct bilateral trade. Atomic onchain settlement.

Questions

Asked before the first trade.

Is Clavius an exchange or a custodian?

Neither. There is no public order book, and Clavius never holds participant funds. Trades settle atomically, participant to participant, between allocations the parties themselves own, with Canton-native finality. Nothing passes through Clavius.

Who sees my trading intent?

Only the counterparties you choose. You define structured intent across liquidity tiers before any order exists, and your order is routed only to the tiers you select. Nothing reaches the wider market.

How is the price determined?

Two ways. Midpoint execution strikes at the mid of an independent reference price, executed against signed Chainlink Data Streams. An RFQ returns live, firm quotes from the liquidity tiers you select, held open for a defined window; you accept the best quote and it binds.

What happens if the other side fails to deliver?

Settlement is atomic on Canton Network, built to the CIP-56 standard. Base, quote and fee move in one indivisible step. All legs settle, or none do; there is no half-settled state.

Who can participate, and what does onboarding involve?

Clavius is built for institutional counterparties: funds, market makers and treasuries whose orders are too large for lit venues. Every participant completes KYB and sanctions screening before any workflow opens, and availability varies by jurisdiction.

What can we trade?

Canton-native assets and stablecoins across supported pairs: rotating treasury positions, filling OTC client orders, and moving cash and tokenised assets between verified institutional counterparties.

What does it cost, and how do we start?

Mainnet beta access is open: register directly at app.clavius.io, complete KYB, and connect your wallet. Founding terms, locked in for early members, are shared on request; write to contact@clavius.io. Beta members get direct access to the founders and the protocol engineering team, and shape midpoint and RFQ semantics and discovery routing before public launch. A testnet sandbox remains available at app-testnet.clavius.io.

Access

Trade with Clavius before public launch.

Join a limited group of institutional trading desks helping shape the venue. The terms reflect it:

  • Preferential founding-member fees, locked in for the life of the cohort.
  • Early access to midpoint and RFQ execution on the live venue.
  • A direct line to the founders and protocol engineers, not a support queue.
  • A hand in shaping execution and discovery routing before public launch.
