Securitize

Securitize is the leading regulated tokenization platform, building the compliance infrastructure that converts real-world assets—from money market funds and private credit to public equity—into blockchain-native securities that can be issued, owned, and transferred on-chain.

Founded in 2017 by Carlos Domingo and Jamie Finn and headquartered in San Francisco, the company has established one of the most complete regulatory stacks in the tokenization industry. Securitize operates SEC-registered entities across four regulated functions: a digital transfer agent that maintains official ownership records on-chain, a broker-dealer for primary issuance and investor onboarding, an Alternative Trading System (ATS) enabling secondary trading of tokenized securities, and a fund administration business handling NAV calculations, distributions, and regulatory reporting. This vertical integration—rare in both traditional finance and crypto—means Securitize can take an asset from structuring through issuance to secondary settlement without handing off to third parties.

The DS Protocol and Compliance Layer

The core of Securitize's technical architecture is its Digital Securities Protocol (DS Protocol), a programmable compliance layer embedded directly into the token contracts it issues. Rather than applying compliance checks at the application level, DS Protocol enforces investor eligibility, transfer restrictions, jurisdiction gates, and lockup periods at the contract level—a token cannot legally transfer to an ineligible wallet regardless of the exchange or interface used. The protocol has evolved through multiple iterations; DS Protocol v4 added new capabilities for expanding real-world asset use cases.

Investor onboarding flows through Securitize iD, the platform's identity and accreditation layer. Investors complete KYC and accreditation verification once; that verified identity is then portable across any offering on the platform. U.S. issuances follow three primary regulatory frameworks: Reg D for private placements limited to accredited investors, Reg A+ for offerings up to $75 million annually that can include non-accredited participants, and Reg S for distribution to non-U.S. buyers outside SEC oversight. European offerings operate under MiCA for unified licensing across EU jurisdictions.

BlackRock BUIDL: The Flagship Partnership

Securitize's most prominent role is as the transfer agent and distribution partner for BlackRock's USD Institutional Digital Liquidity Fund, known as BUIDL—the largest tokenized money market product on public blockchains. BlackRock selected Securitize for this role at the fund's March 2024 launch on Ethereum, simultaneously leading a $47 million strategic investment round in the company. BUIDL holds short-term U.S. Treasuries and cash equivalents and distributes daily dividends to token holders, offering institutional-grade money market yield with blockchain settlement: peer-to-peer transfers 24 hours a day, seven days a week, with near real-time finality compared to the T+1 or T+2 settlement windows of traditional markets.

BUIDL expanded to Solana in March 2025, when the fund held approximately $1.7 billion in assets. The addition of Solana brought BUIDL to seven blockchain networks, alongside Ethereum, Polygon, Aptos, Arbitrum, Optimism, and Avalanche, with Wormhole providing cross-chain interoperability for token transfers between deployments. By mid-2026, BUIDL had grown to approximately $3 billion in total assets, with more than $600 million of that total held on Solana. Bank of New York Mellon serves as custodian for the fund's cash and securities; investor-side custody options span Anchorage Digital, Copper, and Fireblocks. BUIDL tokens are also accepted as collateral on derivatives platforms including Deribit and Binance, extending their utility beyond simple yield-bearing instruments.

Solana Integration

Solana has become a core deployment chain for Securitize. Beyond BUIDL, Solana's throughput and low transaction costs align with the company's vision for financial assets that settle in real time without the overhead of legacy clearing infrastructure.

When Securitize went public on the New York Stock Exchange on July 2, 2026—via a business combination with Cantor Equity Partners II that valued the company at $1.25 billion and raised $400 million—it simultaneously issued $266 million in tokenized SECZ shares on Solana and Avalanche. This made Securitize the first company to debut a publicly listed stock simultaneously on a traditional exchange and on-chain, producing the largest tokenized equity issuance to date. The tokenized SECZ shares represent actual common stock carrying full voting rights and dividend entitlements—not synthetic derivatives or offshore wrappers. Because Securitize controls the full stack from transfer agent to ATS, it can issue native on-chain equity under SEC regulation without relying on DTC custody intermediaries. Trading continued on-chain through the July 4 holiday weekend while traditional markets were closed, demonstrating one of the clearest practical advantages of blockchain settlement over legacy infrastructure.

Separately, Securitize has been named as the first digital transfer agent eligible to mint blockchain-native securities for corporations and ETFs on the NYSE's forthcoming tokenized trading venue. Securitize Markets, the company's broker-dealer arm, is expected to participate as a trading participant on that platform.

Scale and Track Record

As of mid-2026, Securitize manages more than $4 billion in tokenized assets across approximately 650 active funds. The company reported Q1 2026 revenue of $19.5 million, representing 39% year-over-year growth. It employs approximately 254 people and has raised $132 million in total funding across eight rounds from investors including BlackRock, Morgan Stanley, and Blockchain Capital. Securitize was recognized on the Forbes Top 50 Fintech list for 2025.

The platform serves asset managers, DAOs, financial advisors, and direct investors across Ethereum, Solana, Polygon, Avalanche, Arbitrum, Optimism, Aptos, and BNB Chain, allowing issuers to reach investors wherever liquidity and custody infrastructure exists. As CEO Carlos Domingo has stated, the end state for tokenization is a world where the technology simply becomes part of how financial assets are issued, owned, and transferred—not a separate category requiring its own label.
