Product · Custody

Reserves and keys, held to bank standard.

Custody and safekeeping for stablecoin reserves and deposit assets, built around segregation, controls, and independent verification — and integrated today with the institutional custodians your counterparties already use.

Custody is where most stablecoin stories fall apart — and where Stellus is deliberately conservative. Reserve assets backing ozUSD and the deposits behind OZD are held under segregation arrangements designed so that customer assets are never commingled with operating funds and never lent against. Where counterparties prefer to hold or move value through their own institutional custodian, Stellus is integrated with the leading platforms today.

✦ Custody partnerships

Integrated today with institutional custody.

Stellus is live with the qualified custodians and prime infrastructure that regulated counterparties already use to hold and move digital assets.

How custody works at Stellus

  • Segregation

    Reserve and deposit assets are held separately from Stellus operating accounts.

  • Qualified custody

    Reserves are held in cash and short-dated U.S. Treasuries with qualified custodian and banking partners.

  • Key management

    Cryptographic keys are managed under HSM-backed and MPC controls with role separation and audited access.

  • Independent verification

    Holdings are reconciled and reported, and examined by an independent firm. See Attestations.

✦ Cross-chain integrity

Burn-and-mint, not lock-and-wrap.

Most cross-chain "wrapped" assets are locked-and-wrapped: the original token sits in a bridge contract while a synthetic copy circulates on the destination chain. That pattern concentrates value in a small number of bridge contracts — and bridge contracts have been the largest category of loss in on-chain history.

Stellus uses burn-and-mint instead. The token on the source chain is destroyed and an identical token is minted on the destination — one canonical asset, no bridge honeypot, no synthetic copy to depeg.

Two patterns side by side
Lock-and-wrapNot used

Original locked in a bridge contract; a synthetic copy circulates elsewhere. Bridge becomes a single point of failure.

Burn-and-mintStellus default

Token destroyed on source, minted on destination. One canonical asset across chains; no bridge contract to compromise.

Cross-chain transfers are abstracted behind a single intent layer — builders integrate one API across supported networks, not one per bridge.
