BlackRock's BUIDL Digital Liquidity Fund has deployed an additional $500 million in tokenized assets to Aptos, pushing BUIDL's adoption ranking to second place, behind only Ethereum. As of the time of writing, the scale of tokenized RWA assets on the Aptos chain has exceeded $1.2 billion, ranking third overall. The BUIDL fund, jointly launched by BlackRock and Securitize, a tokenization infrastructure platform, uses underlying assets including low-risk, highly liquid assets such as cash, US Treasuries, and repurchase agreements. Initially deployed on Ethereum in March 2024, it was expanded to Aptos and other chains in November 2024. This move reflects the accelerating shift among traditional financial giants toward blockchain infrastructure. Aptos, with its high-performance, secure, and low-cost technology, is becoming a key gateway for institutional asset management on-chain.
