What is BlackRock’s Buidl Fund?
BlackRock USD Institutional Digital Fund, Buidl, is BlackRock’s first tokenized money market fund. This allows these traditional financial products to be traded as cryptographic tokens on the blockchain.
A money market fund is an investment trust that invests in high liquidity, short-term debt certificates. These funds aim to provide investors with a temporary place to park their money, returning the level of income without any major capital gains. It typically includes cash, cash equivalents, and high-risk rating debt securities such as the US Treasury Department.
BlackRock is the world’s largest asset manager. It currently offers a blockchain-based money market through blockchains such as Solana and Ethereum. Essentially, the company adopted the idea of ​​a traditional money market fund, combining it with the payment characteristics of a distributed ledger and blockchain.
The fund has reported explosive growth, surgening from its managed $667 million to $1.8 billion worth of assets in just three weeks. As of March 31, 2025, the fund continues to attract a stable inflow of capital, with the number of crypto-savvy investors choosing to park the fund in Buidl via the seven currently operating blockchains.

The Buidl launch is one of the most important institutional moves, mixing traditional finance (TRADFI) with blockchain-based products. It illustrates another step in BlackRock’s crypto strategy towards the economic acceptance of mainstream crypto and blockchain.
The institution’s crypto adoption from a respected asset manager with managed assets could bring trillions of dollars together to justify the space, causing a new wave of capital inflows from institutional adoption.
How does Buidl work?
Buidl is a tokenized fund. They invest in dollar-equivalent assets like US Treasury bills, cash and repurchase agreements. Investors buy and sell Buidl Tokens. This is fixed in dollars each month, and pays dividends daily to the investor’s wallet each month.
Investors can earn revenue while maintaining the security of traditional financial products. This is a form of real-world asset tokenization (RWA) that involves creating a digital representation of assets.
This digital representation is a blockchain-based token similar to cryptocurrency, and can be traded in related decentralized networks. Traditional assets transfers usually take several days to settle and are inefficient in capital. Tokenized assets allow closer-in-time transactions and settlements to speed up the financial process while also allowing better automation to reduce costs.
A hybrid approach creates Tradfi and Crypto Bridge, providing investors with the best world in both worlds, with the stability of regulated financial products and the efficiency of blockchain.
Did you know? Superstate, part of Sky (formerly Makerdao)’s RWA allocation announced in 2024, secured chunks (estimated $200 million to $300 million) in March 2025, pushing AUM up over $400 million. The tokenized Treasury $5 billion milestone supports this growth.
Why Buidl is important to Crypto
The BlackRock Buidl Fund guides the next level of institutional legitimacy for cryptographic ecosystems. Regulated institutions and entities can confidently enter the blockchain space seamlessly, especially with proven chains such as Ethereum and current Solana.
The fund demonstrates practical and practical use cases of blockchain beyond speculative investment. For many years, crypto investments have been reserved for those brave enough to exchange tokens directly and learn about the complexity of distributed finance (DEFI).
The latter often took too much risk to valuable investments. On top of this, ambiguous regulations made these options completely off limits for fund managers at institutions like BlackRock.
For many years, Crypto has sought the approval and legitimacy of traditional financial institutions. Buidl is more than just acceptance. It is a green light for active participation from the world’s largest financial players. The fund’s early success may be a potential catalyst for the expansion of institutional investments as mainstream adoptions increase.
The impact of Buidl on traditional finance (Tradfi)
Buidl funds are well-known examples of how tokenization and blockchain can improve traditional financial products.
Buidl shows the design possibilities available to further token money markets and RWA.
“Since Buidl’s launch, the demand for real-world assets for tokenization has increased dramatically, enhancing the value of providing institutional-grade products,” said Carlos Domingo, CEO and co-founder of Securitize. “As RWA and tokenized Treasury markets gain momentum and expand Buidl to Solana, blockchain, known for its speed, scalability and cost-effectiveness, is a natural next step.”
Money markets usually allow investors to acquire yields from idle cash, but traditional funds have trading restrictions that allow limited business hours. The introduction of the blockchain version will provide investors with 24-hour access and liquidity.
BlackRock is also not the sole player of tokenized funds. Franklin Templeton released a similar blockchain product that had grown to a market capitalization of over $600 billion by February 2025, but Figure Market launched an interest Stablecoin called YLDS.
Did you know? Beyond traditional institutions, Buidl is attracting interest from native blockchain entities seeking to leverage on-chain utilities. The outstanding early investor was Ondo Finance, relocating $95 million to Buidl from its own tokenized short-term bond fund within a week of its March 2024 launch.
Benefits of Buidl for Investors
While traditional money market funds have been operating for decades, Buidl has introduced several advantages, including speed and accessibility, to bring these financial products into the modern world of digital assets.
Increased speed and efficiency: Buidl Crypto’s investment reduces payment times compared to traditional funds. This reduces administrative burdens and costs while providing overall operational efficiency. Enhanced liquidity and accessibility: Investors can buy and sell fund tokens 24 hours a day, seven days a week. With no closed trading hours or weekends, investors can always maintain liquidity to improve capital efficiency. Generate new yields: In search of a stable value of $1 per token, investors are paid into their daily wallets as monthly tokens. This could potentially provide a higher return compared to traditional fixed income investments. Transparency and Security: All Buidl transactions and holdings are tokenized and registered on the associated blockchain. This means everything is transparent so that investors can enjoy asset visibility and accountability.
Buidl’s risks and challenges
Buidl’s rapid growth is a positive sign of Tradfi and blockchain innovation. Still, it also introduces risks that many investors may not know well. This is an important consideration for the money market as factors such as liquidity and technological vulnerability have evolved.
Understanding these new elements is essential for investors.
Liquidity Issues: Liquidity is important for successful asset classes, especially in derivative products. Buidl has some liquidity concerns on an investor base, which is currently made up of qualified investors, ignoring the adoption of a wide range of markets. Technical vulnerabilities: Buidl’s foundations leverage Ethereum’s ability to tokenize the U.S. Treasury Department of the Swiss contract capabilities. The smart contract vulnerability here can expose the fund to failure or hacking. Market Operation: Cryptocurrencies are often volatile for market operations, as they often carry out tactics such as washing transactions and pump and dump schemes. As a new tokenized product, Buidl can be vulnerable to this type of risk due to limited trading volume and liquidity. Counterparty Risk: BlackRock is a reliable and secure financial institution. But counterparty risk is important in crypto. For example, if an exchange-listed Buidl is facing economic distress, it could affect the reliability of the token.
