@BlackRock's tokenized treasury fund, BUIDL (BlackRock USD Institutional Digital Liquidity Fund), recorded $52 million in fresh inflows within a single 24-hour window, adding to a growth story that has made it one of the dominant forces in on-chain fixed income.
BUIDL is a tokenized money market fund launched in March 2024 with Securitize as transfer agent.Yield flows from US Treasury bills, repurchase agreements, and cash held by BNY Mellon.Each BUIDL token targets a stable $1 net asset value and accrues yield daily via a rebase mechanism, and the fund is restricted to qualified purchasers with a $5 million minimum subscription.
In mid-July 2026, BlackRock's BUIDL fund added $436 million in assets on the Avalanche blockchain in a single week, a 105% weekly gain that brought its Avalanche holdings above $900 million, pushing BUIDL's total assets under management across all networks to approximately $2.87 billion.Securitize, which manages the fund as transfer agent, began trading on the New York Stock Exchange in July 2026 under the ticker "SECZ" and manages over $3 billion in total value locked through BUIDL.
Since its inception, the fund has distributed dividends exceeding $100 million, demonstrating the real-world yield this model can generate.Unlike speculative crypto tokens, BUIDL is a regulated investment product offering Treasury-bill yields currently estimated at approximately 4.5 to 5.0% APY with on-chain accessibility.
BUIDL leads the broader tokenized US Treasury category, which has grown from approximately $1 billion in early 2024 to more than $15 billion by Q2 2026.This success has demonstrated that institutional demand for on-chain, yield-bearing dollar instruments is not just theoretical but substantial and growing.
The integration with BNB Chain and Binance's approval of BUIDL as off-exchange collateral in November 2025 further enhanced its utility and liquidity, allowing institutional traders to leverage tokenized Treasuries for margin, bridging traditional fixed income with active crypto markets.
BlackRock has also filed with the SEC for two new tokenized funds to complement BUIDL, including a tokenized version of the BlackRock Select Treasury Based Liquidity Fund (BSTBL) and BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV), a blockchain-native tokenized money market fund. The moves signal that BlackRock views tokenized fixed income as a permanent part of its product lineup rather than an experiment.
