Sovereign Network Interoperability keeps assets on native ledgers

Sovereign Network Interoperability is Consensys's bid to give banks, custodians and market infrastructures a delivery-versus-payment and payment-versus-payment route that leaves each asset on the ledger already recording it. The company introduced the stack in Mumbai on November 2, 2026, during DevCon, for firms that run their own networks and still need a counterparty on another one. Payment-versus-payment venues were built after Herstatt so the two currency legs finish together. Consensys wants that pairing while each institution keeps its own ledger, its own data and its own controls.

Consensys describes Sovereign Network Interoperability as routing, execution coordination and transaction tracking in one product. The institution sets the action, the approved counterparties and the settlement requirements. The software picks a route, coordinates execution and tracks the result through completion or a stop that needs a person. The core protocol is the Cross Ledger Interoperability Protocol (CLIP), credited to a decade of Consensys work and to zero-knowledge proof research. Assets stay on their native ledgers, and cryptographic proofs check the cross-ledger state.

Four workflows from one instruction

The November 2 announcement sets out four workflows for banks, custodians, asset managers and financial market infrastructures.

• Collateral mobility posts eligible collateral from an asset platform to a clearing house or another approved counterparty.
• Securities settlement delivers a tokenised security on one ledger against payment on another.
• Wholesale payments connect banks' currency ledgers so both foreign-exchange legs finish under payment-versus-payment conditions.
• Funds servicing lets a treasurer move idle cash into a tokenised money-market fund and back at any hour, settling deposits against fund units in one step.

Synchronous finish, asynchronous recovery

Consensys says every connection settles atomically, either synchronously or asynchronously depending on topology. Asynchronous atomicity means both legs commit, or the agreed recovery time and recovery point objectives unwind a break. Each participating ledger still carries trust assumptions in its consensus, its verification software and its operational controls. The company says proof checks stand in for an extra verification intermediary and keep sovereign data with the participants allowed to see it. The post names no production flow and no customer that has completed one.

Ethereum-compatible chains are available now, and Canton comes next. Sovereign Network Interoperability will also support the open Ethereum Economic Zone standard, the Inter-Blockchain Communication protocol and a planned Canton connection. Canton describes itself as a public blockchain with privacy built for regulated markets. The IBC documentation describes an open-source protocol for connecting independent ledgers. Those pages carry no statement that either network has switched this product on.

Inside the institutional company

On September 9, 2026, in Fort Worth, Consensys Software Inc. said it would become two companies. The consumer platform continues as MetaMask under Joe Lubin as chairman and chief executive. The protocols and institutional business keeps the Consensys name, with Mike Kriak as chief executive, David Cunningham as president and Joe Lubin as executive chairman. David Cunningham, president of Consensys, said in the November 2 release: "Institutions need to reach new and existing counterparties without sacrificing privacy, while keeping control of their infrastructure. We are bringing deep protocol expertise, transaction coordination and complete support into one product. The result is a simpler path to each new connection, with verifiable outcomes and clear accountability for keeping the full stack working for years to come."

Institutions can operate the product themselves, through a financial market infrastructure, or as a Consensys-managed service. Consensys supplies the technology and the maintenance in every model, including security fixes, upgrades, monitoring and revalidation when a network changes. Pricing is scoped to setup, recurring support, managed operations and transaction services.

Consensys says it created and maintains Besu, the open-source Ethereum client many institutional ledgers run, and that it builds Lineth, Teku and Web3Signer. CDK Besu is already live on Ethereum mainnet for private chains, a permissioned Ethereum (ETH) ledger of the kind this product is built to connect while assets stay on the record that already holds them. An existing network can start with one supported connection.

Partior's instant payments still leave its four settlement banks to square up the old way, the bank-leg gap a payment-versus-payment coordinator would have to close. Aviva's Sterling Liquidity Fund has added a tokenised share class, a cash-fund unit of the sort the funds workflow targets. Quant now sits under both US and UK tokenised deposit rails. Consensys names no launch customer and no date for the Canton connection. A named market infrastructure and a published Canton adapter would show the stack operating in a live market.
