Dinari has opened tokenized access to every S&P 500 company for eligible users across the United States, offering 724 tokenized stocks through its regulated dShare infrastructure. The launch enables users to purchase blockchain-based shares directly from self-custody wallets funded with Circle's USDC stablecoin, with each token backed one-to-one by an underlying security held by a regulated custodian. The S&P 500 is the most widely followed benchmark for large-cap US equities, and making its full roster available as blockchain-based tokens marks one of the broadest domestic tokenized equity rollouts to date.

Tokenized Shares Replace Traditional Brokerage Access

Dinari's dShare tokens cover all constituents of the S&P 500 index plus additional equities. Eligible users can trade these assets from compatible wallets without opening conventional brokerage accounts. The service currently operates across Ethereum, Arbitrum, Base, and Avalanche, with support for Solana and Sei planned as the platform expands its blockchain coverage. Multi-chain deployment addresses a practical concern in tokenized markets—liquidity and user fragmentation across networks—by letting participants access the same underlying assets from whichever chain they already use.

The wallet-first model allows users to fund accounts using USDC, linking stablecoin payments with regulated exposure to publicly traded American companies. Each dShare is backed by an actual underlying stock held securely with a regulated custodian. Holders receive dividends, voting rights, redemptions, and other corporate actions connected to those shares. The platform distributes cash dividends in USDC and records ownership through blockchain infrastructure.

USDC Supports Settlement and Dividend Payments

USDC serves as the backbone of Dinari's equity service, handling account funding, trade settlement, and dividend distribution. The company developed the system in partnership with Circle and several wallet infrastructure providers, including Privy, Para, and Monaco, which support components of the access and transaction process.

Blockchain settlement enables tokenized portfolios to move faster than standard market systems, which in the US operate on a T+1 settlement cycle following the Securities and Exchange Commission's May 2024 rule change. Users can transfer supported assets between compatible platforms rather than remaining confined to a single brokerage network, though each transfer must satisfy applicable eligibility, compliance, and custody requirements.

Dinari operates through a registered broker-dealer and an SEC-registered transfer agent. Its broker-dealer subsidiary is a member of both FINRA and SIPC, providing the regulatory structure necessary for tokenized equity trading within the United States. That registration stack places Dinari within the existing federal securities framework rather than operating outside it, a distinction that has shaped how other tokenized asset platforms have entered or been blocked from the US market.

Competition Grows Across Tokenized Equity Markets

Dinari enters a market that has expanded rapidly as financial firms explore blockchain-based securities. According to an a16z crypto report, tokenized stocks reached a valuation of approximately $1.7 billion by the end of June, reflecting estimated growth of about 600% as more platforms introduced digital versions of traditional shares. That growth forms part of a broader real-world asset tokenization trend that has drawn participation from major institutions, including BlackRock, which launched a tokenized Treasury fund on Ethereum in 2024.

Robinhood and Kraken-linked Payward already offer tokenized stock products outside the United States. Ondo Finance has proposed a regulated framework tied to public equities and exchange-traded funds, though that product does not yet serve eligible users within the country.

Dinari currently operates across 85 jurisdictions and supports more than 6,000 active tokenized assets. The company launched the Dinari Financial Network to connect issuers, custodians, exchanges, and transfer agents. The S&P 500 rollout extends that regulated infrastructure directly to eligible US users.
