Securitize Proposes BlackRock's BUIDL Fund as Collateral for Frax USD Stablecoin

In a significant move for the decentralized finance (DeFi) and stablecoin space, Securitize, the brokerage firm handling the tokenized version of BlackRock's US Dollar Institutional Digital Liquidity Fund (BUIDL), has submitted a Frax Improvement Proposal (FIP) to introduce BUIDL as a collateral reserve for the Frax USD stablecoin. The proposal is still subject to a community vote, but if approved, it could mark a major shift in the way stablecoins are backed and utilized within the crypto ecosystem.

What is BUIDL and Why It Matters?

The BUIDL fund, managed by BlackRock, currently holds approximately $549 million in assets under management. This fund primarily invests in U.S. government securities, which offers a stable and low-risk backing for its tokenized version. Tokenized real-world assets (RWAs) like BUIDL are becoming increasingly popular in the crypto space due to their potential to provide both high yield opportunities and liquidity for stablecoins.

BUIDL's unique characteristics offer several advantages. As collateral for Frax USD, it provides enhanced yield potential, deeper liquidity, and reduced counterparty risk, thanks to the backing of BlackRock — the world’s largest asset manager. With BlackRock’s name and track record behind it, BUIDL is seen as a safe and reliable asset to support the stability of the Frax USD stablecoin, which is designed to maintain a 1:1 peg with the U.S. dollar.

The Role of Tokenized RWAs in Stablecoin Innovation

The proposal to use BUIDL as collateral aligns with a broader trend in the stablecoin market: tokenized RWAs are gaining traction as a more efficient, transparent, and secure alternative to traditional collateral reserves. These assets allow for faster transaction finality, cost efficiencies, and new yield-bearing opportunities for stablecoin holders.

As stablecoins continue to play a central role in the DeFi ecosystem, integrating high-quality, low-risk assets like BUIDL could enhance the stability and attractiveness of these digital currencies. The addition of BUIDL as collateral would not only strengthen Frax USD's position in the market but also provide unique growth opportunities for investors and users alike.

The Growing Influence of BUIDL in the Crypto Space

The potential integration of BUIDL into Frax USD follows a series of strategic moves in the crypto space. In September 2024, Ethena Labs, the developer behind the USDe synthetic dollar, announced plans to launch a BUIDL-backed stablecoin, USDtb. The new stablecoin went live on December 16, 2024, and gained significant traction, accruing around $65 million in total value locked (TVL) on its first trading day.

USDtb operates on a simple overcollateralization model, backed 1:1 by cash and short-term U.S. government securities held by the BUIDL fund. Unlike USDe, which employs a more complex delta-neutral strategy to issue stablecoins, USDtb aims to offer a straightforward, highly secure stablecoin backed by reliable assets.

Moreover, BUIDL’s increasing presence in the crypto derivatives market is noteworthy. In October 2024, BlackRock began discussions with major crypto derivatives exchanges, including Binance, OKX, and Deribit, to incorporate BUIDL as collateral for trading. This could pose a challenge to the dominance of existing stablecoin issuers like Tether and Circle, who currently hold the lion's share of collateral reserves in the crypto derivatives space.

BUIDL’s Expanding Ecosystem

In addition to its potential integration with Frax USD, BUIDL is also being used in decentralized finance platforms. For instance, the Elixir Protocol’s deUSD yield-bearing stablecoin, launched in November 2024, allows users to mint the stablecoin on Curve, a decentralized exchange, using BUIDL as backing collateral. deUSD can then be exchanged with other stablecoins in Curve’s liquidity pools, further demonstrating the versatility and appeal of BUIDL as a reserve asset.

Conclusion

Securitize’s proposal to use BlackRock’s BUIDL fund as collateral for Frax USD represents an important step in the evolution of stablecoins and tokenized RWAs. If the community vote is successful, it could pave the way for a new era of highly stable, yield-bearing, and secure stablecoins that are backed by trusted, real-world assets. As BUIDL continues to gain traction across DeFi platforms and crypto exchanges, its role as a collateral asset is likely to expand, challenging traditional stablecoin issuers and reshaping the landscape of digital finance.
