BlackRock Launches Its BUIDL Tokenized Fund on Ethereum: A Historic Step for Real-World Asset Tokenization

As bitcoin trades around $62,030 this Monday, July 13, 2026, at 18:00 UTC, a major event is shaking up the digital asset ecosystem: BlackRock, the world’s largest asset manager with trillions of dollars under management, has officially launched its tokenized BUIDL fund (BlackRock USD Institutional Digital Liquidity Fund) on the Ethereum blockchain. This decision marks a decisive turning point in the institutional adoption of real-world asset (RWA) tokenization.

What Is BlackRock’s BUIDL Fund?

BUIDL — an acronym for BlackRock USD Institutional Digital Liquidity Fund — is a money market fund backed by U.S. Treasury bills that BlackRock has chosen to tokenize on the Ethereum blockchain. Concretely, it is a traditional fund—a money market fund invested in short-term U.S. government securities—whose shares are represented as digital tokens on a public blockchain.

This tokenization was carried out in partnership with Securitize, a platform specialized in the issuance and management of tokenized digital securities. Securitize acts as transfer agent and tokenization platform, enabling BlackRock to offer shares of its fund in the form of tokens compatible with the Ethereum ecosystem.

The choice of the name BUIDL is no coincidence: it refers to the famous crypto community slogan “BUIDL” (a deliberate play on words replacing the traditional “HODL”). This linguistic nod demonstrates BlackRock’s desire to speak the language of the crypto ecosystem while bringing the weight of traditional finance.

Why Is BlackRock Interested in Tokenization?

BlackRock is not a newcomer to the digital asset space. The American giant has already made headlines by filing for a spot bitcoin exchange-traded fund (ETF), followed by an ether ETF—products that were approved by the U.S. Securities and Exchange Commission (SEC) after years of rejections. These ETFs paved the way for massive adoption by institutional investors, who can now gain exposure to bitcoin and ether through regulated, familiar investment vehicles.

With BUIDL, BlackRock goes further. It is no longer simply about offering passive exposure to cryptocurrencies, but rather tokenizing a traditional financial product—a money market fund—to make it accessible and transferable on a blockchain. This move is part of a broader trend that analysts call the “tokenization of the real world”: converting traditional assets (bonds, stocks, real estate, commodities) into digital tokens that can be traded 24/7 on decentralized infrastructures.

For BlackRock, the benefits are numerous. Tokenization allows for greater operational efficiency: settlements can be automated via smart contracts, reducing delays and administrative costs. It also offers enhanced transparency, since transactions are recorded on a public blockchain. Finally, it opens the door to unprecedented financial composability: tokenized fund shares can be used as collateral in decentralized finance (DeFi) protocols or integrated into programmable financial products.

Ethereum at the Heart of the Institutional Strategy

The choice of Ethereum as the host blockchain for BUIDL is highly significant. Ethereum is the leading smart contract platform, hosting thousands of decentralized applications and the vast majority of DeFi protocols. By choosing Ethereum, BlackRock is leveraging the most proven and liquid infrastructure in the digital asset ecosystem.

This decision also validates the narrative that Ethereum could become the “settlement layer” for traditional finance. If the world’s largest asset manager chooses Ethereum to tokenize its products, other institutions may follow suit. The precedent is now set: a public blockchain can host top-tier regulated financial assets.

For Ethereum, BlackRock’s arrival brings additional legitimacy. The blockchain, which underwent a major transition to proof-of-stake with “The Merge” in 2022, is gradually establishing itself as the go-to platform for institutional asset tokenization. Projects like Tokenized TBills, Ondo Finance, and Matrixdock had already paved the way by tokenizing Treasury bills, but with BlackRock, the weight of traditional finance is now directly entering the chain.

It is worth noting that ether is trading around $1,780 at the time of writing, in a market context that remains cautious despite positive institutional announcements.

The RWA Market: A New Frontier for Crypto

The launch of BUIDL by BlackRock is part of the rapid emergence of the tokenized real-world assets (RWA) market. This segment of decentralized finance aims to bring onto the blockchain assets that exist in the real world—government bonds, private debt, real estate, works of art—in order to benefit from the liquidity, transparency, and efficiency of digital infrastructures.

The concept is simple but powerful: rather than creating purely digital assets with no real-world backing (like certain speculative tokens), RWAs are based on existing tangible or financial assets. The shares of the BUIDL fund, for example, represent a claim on a portfolio of U.S. Treasury bills—one of the safest assets in the world. By tokenizing this fund, BlackRock allows institutional investors to hold and transfer shares of this fund with the speed and flexibility of an ERC-20 token on Ethereum.
