Summary
BlackRock's USD Institutional Digital Liquidity Fund (BUIDL) has demonstrated exceptional momentum in the tokenized asset market, with its Avalanche allocation doubling to $900 million in a single week. The expansion—adding approximately $436 million from a previous $464 million—represents a 105% weekly increase and underscores growing institutional appetite for blockchain-based Treasury access. As of July 12, BUIDL's combined assets across all supported networks reached approximately $2.87 billion, according to RWA.xyz data cited by Wu Blockchain and other market monitors.
The concentration of growth on Avalanche reflects the network's increasing significance in the real-world asset (RWA) tokenization ecosystem. Avalanche now ranks as BUIDL's second-largest blockchain allocation, representing nearly one-third of the fund's total assets and surpassing other networks where the fund operates. This shift demonstrates both Avalanche's technical appeal for institutional-grade financial infrastructure and the broader shift toward multi-chain deployment strategies for tokenized assets.
BUIDL launched in March 2024 through Securitize and initially deployed on Ethereum before expanding to Aptos, Arbitrum, Avalanche, Optimism, and Polygon in November 2024, subsequently reaching Solana and BNB Chain. The fund invests primarily in U.S. Treasury bills, cash, and repurchase agreements, targeting current income while maintaining principal stability and liquidity. Shareholders receive tokenized fund shares with daily accrued dividends, subject to eligibility and transfer controls, with a maintained target value of $1 per share and a current seven-day annualized yield of approximately 3%.
BlackRock's expansion of BUIDL across multiple blockchains serves institutional investors seeking efficient on-chain Treasury exposure with settlement flexibility. BNY Mellon administers the fund across both digital and traditional systems, ensuring institutional-grade custody and operational standards. Additionally, Binance has enabled BUIDL as off-exchange collateral for digital asset trading—a designation shared by only three tokenized products—expanding its utility within institutional trading workflows. This multi-network approach and expanding use cases position BUIDL as a foundational infrastructure asset for institutions seeking blockchain-native access to traditional fixed-income instruments.
