BlackRock's BUIDL Fund has re-invested $500 million in Aptos, bringing the total on-chain tokenization of RWA to $1.2 billion.

BlackRock invests an additional $500 million in Aptos through the BUIDL fund, with the scale of RWA tokenization jumping to third in the world. (Background: BlackRock CEO: Crypto wallet scale exceeds $4 trillion, “asset tokenization” is the next financial revolution) (Additional Background: BlackRock takes action again: After Bitcoin, they want to bring traditional ETFs on-chain) Wall Street asset management leader BlackRock (BlackRock) is once again adjusting its strategy. The BUIDL fund added $500 million in October towards the high-performance public chain Aptos, pushing the total amount of real-world assets (RWA) tokenized on Aptos to approximately $1.22 billion, second only to Ethereum and ZKsync Era, rising to third across all chains. BlackRock is heavily betting on the Aptos BUIDL fund and Securitize, launching in March 2024 on Ethereum, specifically to map U.S. Treasury bonds, cash, and repurchase agreements onto the chain. In November of the same year, the fund will deploy cross-chain, with Aptos becoming a new node. After this $500 million injection, Aptos ranks just below Ethereum in terms of scale among all landing chains in the BUIDL ecosystem, reflecting large institutions' trust in transaction speed, security, and low Gas costs. Blockchain tokenization of RWA values: Ethereum $12.09 billion, ZKsync Era $2.36 billion, Aptos $1.22 billion, Polygon $1.13 billion, Arbitrum $904 million. What technical conditions of Aptos attract institutions? The consensus mechanism of Aptos is designed for high concurrency paired with a modular execution environment, with single block processing capabilities far exceeding similar L1s, and the Move language reduces the risk of smart contract vulnerabilities, forming a basis of security and compliance that institutions prioritize. For BlackRock, a multi-chain layout can disperse technical and regulatory risks, and Aptos provides an efficient entry point outside of Ethereum, allowing RWA products to avoid being completely constrained by Ethereum's transaction fee bottleneck. Market participants point out that Aptos' push for low latency (sub-second finality) allows treasury bond tokens to settle as quickly as money market funds, further enhancing liquidity; and most assets corresponding to BUIDL are low volatility instruments, which further highlights the earnings amplification effect brought by the difference in Gas costs. RWA tokenization diffusion effect: RWA tokenization has moved from concept to scale competition. Traditional giants like Blackstone and Fidelity are testing on-chain treasury bonds and notes, and the product line claiming to be “on-chain money market funds” is rapidly expanding. BlackRock's continued entry has “revealed the next main axis of the crypto market,” quoting Wall Street analysts: RWA packages familiar assets, which not only broadens the application scope of blockchain but also makes it easier for regulatory bodies to assess risks. After Trump's administration returns to the White House in 2025, the market expects financial supervision to adopt a “technologically neutral, functionally regulated” approach to on-chain assets. BlackRock is traditionally sensitive to policy rhythms, and establishing multi-chain outposts in advance may win time-difference benefits when new rules are implemented.
