Dinari Launches First Tokenized U.S. Stocks for Self-Custody Trading via USDC Partnership

Dinari has launched the first tokenized U.S. stocks available to domestic investors and businesses, bridging the $75 trillion equities market with the $307 billion stablecoin sector. This development allows market participants to trade S&P 500 securities using USDC from self-custody wallets, marking a significant shift in how traditional assets are accessed and managed.

What was announced

Dinari, a specialist in the custodial model of tokenized equities, has partnered with Circle to enable U.S. investors to buy and sell stocks using USDC. The platform introduces dShares™, which are tokenized versions of U.S. equities backed 1:1 by underlying securities held in qualified custody. At launch, the offering includes the entire S&P 500®, providing a digital bridge to the foundation of global capital markets.

The system is designed to maintain the legal and financial protections of traditional stock ownership. This includes National Best Bid and Offer (NBBO) execution, voting rights, dividends, and corporate actions. A key feature of the launch is native USDC dividend support, which allows eligible investors to receive payments directly in stablecoins, facilitating immediate reinvestment within the digital asset ecosystem.

The service is currently available through the Dinari Trading App and a network of launch partners, including Monaco, Eldora, Kredete, Yield.xyz, Liminal, Para, Privy, and Axal. Technically, Dinari supports the Avalanche, Arbitrum, Base, and Ethereum Mainnet blockchains. The company has also indicated that support for the Sei and Solana networks is expected in the near future. This expansion follows Dinari's existing international operations, which already serve investors across more than 85 jurisdictions through neobanks and web3 platforms.

"We're the first platform to let U.S. investors buy and sell tokenized U.S.-listed stocks directly from their own self-custody wallets using USDC. For decades, investing and digital assets have existed in separate financial systems. This launch brings them together, allowing investors to move seamlessly between stablecoins and U.S. equities while preserving the protections of traditional capital markets."

Gabriel Otte, CEO and Co-Founder of Dinari.

The companies involved

Dinari is a leader in the custodial model of tokenized equities, focusing on bringing highly regulated traditional securities onto blockchain infrastructure. The company operates at the intersection of decentralized finance and traditional brokerage, ensuring that digital representations of stocks are fully backed by physical assets held in qualified custody.

Circle is the issuer of USDC, a leading regulated stablecoin that has become a primary medium for value transfer across digital markets. Circle has been a central figure in the push for dollar-backed digital assets that comply with transparency and reserve requirements. The launch also involves several infrastructure and fintech partners: Liminal, a digital asset custody platform; Axal, which focuses on autonomous finance; and Privy, a provider of onboarding tools for web3 applications. The underlying technology utilizes major blockchain networks including Ethereum, a decentralized global software platform, and Avalanche, a high-performance network designed for financial applications. The regulatory landscape for these activities involves oversight from bodies such as the SEC and FINRA, which govern the issuance and trading of securities in the United States.

What FF News has reported before

FF News has previously tracked the integration of USDC across various financial ecosystems. This includes coverage of Finassets.io Launches USDC on Solana to Slash Crypto Payment Costs for Merchants, highlighting the stablecoin's utility in reducing transaction friction. We have also reported on the broader tokenization trend, such as when Securitize and Neuberger Launch HINC: A Multi-Chain Tokenized Fixed Income Fund, demonstrating the growing institutional appetite for on-chain real-world assets. Additionally, our coverage of Wyoming Stable Token Commission Migrates to Chainlink CCIP for Enhanced Security reflects the ongoing maturation of the regulatory and technical infrastructure supporting these digital instruments.

What this means

This announcement moves the needle by finally bringing the "holy grail" of tokenization—U.S. equities—to domestic investors in a self-custodial format. By enabling USDC-based trading for the S&P 500, Dinari is putting direct pressure on traditional retail brokerages that rely on legacy settlement cycles and siloed cash accounts. The introduction of native USDC dividends is a particularly aggressive move, as it bypasses the traditional banking system's delays.

However, the sector now faces critical questions regarding liquidity fragmentation across the multiple supported blockchains like Avalanche and Arbitrum. While the promise of T+0 settlement and 24/7 trading is inherent to the technology, the industry must now prove it can maintain these benefits while adhering to the rigorous compliance standards of the SEC and FINRA in a live U.S. market environment.
