R3

R3 is an enterprise blockchain company founded in 2015 by David Rutter, best known as the creator of Corda, a permissioned distributed ledger platform built for regulated financial institutions. Since 2025, R3 has repositioned itself at the intersection of institutional finance and public DeFi, launching the Corda Protocol on Solana and connecting its established network of over 200 banks to Solana's public liquidity layer.

Background

R3 emerged from a consortium model, bringing together major financial institutions to build shared infrastructure for regulated markets. Corda — the company's flagship permissioned blockchain — processes transactions for banks, brokerages, and market infrastructures without exposing business data publicly. Its client list includes DTCC, Mastercard, Nasdaq, HSBC, and J.P. Morgan. By mid-2026, Corda networks carried approximately $17 billion in tokenized real-world assets, including bonds, treasury instruments, private credit, and trade finance paper — at the time roughly a third of the entire public RWA tokenization market.

Strategic Pivot to Solana

In 2025, R3 signaled a decisive shift: bringing its institutional network into contact with public blockchain infrastructure. R3 chose Solana following extensive technical and commercial evaluation, citing Solana's throughput, low transaction costs, Token-2022 compliance tooling, and composability with DeFi protocols — over Ethereum, which leads the RWA market by capital deployed.

Lily Liu, then Solana Foundation Board President, joined R3's board as part of the collaboration, reflecting a deep institutional partnership rather than a standard technical integration.

Two Complementary Solana Offerings

R3's Solana presence consists of two linked but distinct products.

Corda Protocol — The DeFi Layer

Announced in December 2025 and developed on behalf of the R3 Foundation, the Corda Protocol (corda.xyz) is a Solana-native curated yield vault platform. It acts as a bridge between institutional RWA issuers and DeFi demand for yield.

The mechanism is direct: institutional asset managers construct and manage yield strategies anchored to real-world assets — tokenized debt instruments, investment funds, and reinsurance-linked securities. DeFi participants deposit stablecoins or other digital assets into these vaults and receive liquid vault tokens in return. Those tokens are fully composable: they can be deployed across other Solana DeFi protocols as collateral or within integrated strategies, without sacrificing the underlying RWA exposure.

The vaults are designed to strip out the structural inefficiencies of traditional fund access. Subscriptions and redemptions operate without the cash drag inherent in conventional fund structures. Onboarding uses a permissioned flow that handles investor eligibility requirements without the weeks of paperwork standard in TradFi RWA products.

EPIC, the first vault under the Corda Protocol, targets 10% annual returns derived from real-world assets issued by established financial institutions. Prior to launch, the protocol attracted more than 30,000 pre-registrations.

Corda Notary on Solana — The Infrastructure Layer

In August 2026, R3 and SIX Group completed the deeper integration: a direct connection between Corda networks and Solana mainnet. Corda Enterprise 4.14 ships with a Solana notary implementation. The on-chain component is an Anchor program deployed to Solana mainnet and devnet that tracks consumed Corda state references stored as hashes. Business data — the actual bond terms, counterparties, and settlement amounts — never touches the public ledger. Only state commitments do.

This architecture allows a bank to notarize a confidential transaction on Solana while revealing nothing about the underlying asset, price, or counterparties. The result is that $17 billion in institutional assets that have existed entirely behind permissioned walls can now access public liquidity without bridges, wrappers, or loss of regulatory control. Assets remain on the Corda networks they originated on; what changes is their ability to interact with the public settlement layer.

Token Structure

The Corda Protocol does not use a native governance or utility token. The primary instruments are vault tokens — liquid representations of shares in curated RWA strategies, issued in exchange for stablecoins at deposit. These vault tokens use Solana's Token-2022 standard, which provides programmable transfer restrictions, confidential transfer capabilities, and identity-aware token accounts, enabling the compliance controls that institutional participation requires.

Security

Smart contracts underpinning the Corda Protocol have been audited by Halborn. The protocol additionally uses permissioned wallet controls and multisig approvals for asset management operations, with assets reconciled between off-chain custody records and on-chain positions for transparency.

Team and Governance

R3 was founded by David Rutter, who has driven the company's strategic expansion into public blockchain markets. The Solana collaboration was formed in partnership with the Solana Foundation.

Governance of the Corda Protocol sits with an independent organization, the Corda Foundation, formed in summer 2025 to steward the protocol's development in a Web3-native manner. The foundation is led by Todd McDonald (President), Kate Walters (Director and General Counsel), and Ruben Khadiullin (Head of Strategy). R3 acts as the primary technology service provider to the foundation under this structure, separating operational delivery from protocol governance.

Solana Ecosystem Fit

R3's arrival on Solana represents one of the most substantive enterprise-to-DeFi connections attempted at scale. Rather than simply tokenizing an asset and listing it on a DEX, the Corda-to-Solana integration connects the full lifecycle of institutional asset management — issuance, custody, compliance, and settlement — to Solana's public infrastructure.

For Solana DeFi, the Corda Protocol adds a new category of yield: professionally managed, RWA-anchored returns composable with existing protocols. Stablecoin holders gain access to tokenized debt instruments and reinsurance securities without leaving the Solana DeFi stack. For institutional participants, Solana provides the throughput and cost profile capable of handling settlement volumes at financial-market scale.

The partnership also carries a broader signal: R3 evaluated Ethereum — the dominant platform for RWA tokenization by capital deployed — and chose Solana. That decision, made by a company with 200 bank relationships and a decade of institutional blockchain infrastructure, is likely to influence how subsequent institutional deployments weigh public blockchain platform choice.
