Prividium Connect

Private, bridgeless transactions across blockchains

Exchange assets with another institution in a single transaction: either both parties receive the agreed assets, or neither transfer goes through. You keep your existing systems and control of your data.

Delivery versus payment

The buyer receives the securities and the seller receives payment in one transaction. Neither leg executes unless both do.

Payment versus payment

Two payments, in the same or different currencies, complete together across blockchains, so neither party pays without being paid.

Multi-party bundles

Several trades among several institutions complete as one bundle. Every trade in the bundle executes together, or none does.

Exchange risk across blockchains

Existing interoperability protocols relay and authenticate messages between blockchains, but an authentic message alone does not ensure that both parties receive what they are owed. If your institution delivers first, it is exposed to the counterparty until the other transfer completes. Institutions cover that exposure with collateral, credit limits or an intermediary.

For private chains, the records needed to check those obligations must also stay confidential.

Delivery and payment in one transaction

Prividium Connect makes the two transfers a single transaction. The buyer receives the securities and the seller receives payment, or neither transfer goes through.

Completion requires zero-knowledge proofs that both sides met the agreed terms, without revealing the records behind them.

A buyer on Ledger A and a seller on Ledger B settle a securities trade. The exchange authorizes the payment leg and the delivery leg, then both legs execute in one transaction: the buyer receives the securities and the seller receives payment at the same time.

Multi-party trades as one bundle

A bundle links several trades among several institutions, such as a securities delivery, its payment and the currency exchange that funds it. Every trade in the bundle executes together, or none does, so no participant is left with a partial outcome.

A bundle of three legs among ledgers A, B and C: securities, payment and FX. When every leg is authorized, all three execute together. When the FX leg is refused, none of the legs executes.

Finality on the settlement layer you choose

Participants choose the settlement layer on which the proven outcome becomes final for both sides. It receives commitments and proofs only, so it can verify the exchange without seeing the accounts, balances or transfers behind it.

Ledger A and Ledger B keep their accounts, balances and transfers private. Each sends only commitments and ZK proofs to the settlement layer, which verifies the proofs and settles the exchange.

Your existing systems

Institutions can use Prividium Connect with their existing blockchains, including Hyperledger Besu and Prividium Ledger, without replacing the infrastructure they already run. Each institution operates its own connector beside its ledger.

Prividium Commander integrates natively with Prividium Connect. Connect can also be used without Commander.

Two institutions keep their own blockchains: one runs Hyperledger Besu, the other Prividium Ledger. Each operates its own connector beside its ledger, and Prividium Connect carries messages both ways between the two connectors.

Frequently asked questions

Does an atomic transaction complete instantly?

No. Atomic means the legs are conditional on each other: they complete together or not at all. Completion still follows the execution steps of the participating systems, including proof verification and finality on the settlement layer the participants chose.

How is the exchange enforced without a bridge?

Prividium Connect allows completion only with zero-knowledge proofs that both sides met the agreed terms. Each side accepts an operation only when its proof verifies and it belongs to the settlement history both parties accept, so no bridge operator confirms that a leg happened.

What happens if one leg cannot complete?

No leg executes. Every leg is conditional on the others, so a refused or failed leg stops the whole exchange. An interruption can leave a transaction pending; the available retry, cancellation or recovery procedure depends on the transaction involved.

What can counterparties and the public see?

Each counterparty receives the information required for its transaction and controls further authorized disclosure of its confidential records, including to auditors and regulators. The settlement layer receives commitments and proofs, not your accounts, balances or transfers.

Which systems can take part?

Existing blockchains, including Hyperledger Besu and Prividium Ledger, without replacing the infrastructure an institution already runs. Each institution operates its own connector beside its ledger. Supported configurations are confirmed for each implementation.

Do I need Prividium Commander to use Prividium Connect?

No. Prividium Connect can be used on its own. Institutions that use Prividium Commander, our software for privacy and control over institutional infrastructure, benefit from its native integration with Connect.
