The world of finance is undergoing a quiet revolution—one powered by blockchain technology and the tokenization of real-world assets (RWAs). At the forefront of this transformation stands BlackRock’s BUIDL, a tokenized U.S. Treasury fund that has surged past **$1.4 billion in assets under management (AUM)**, nearing the $1.5 billion milestone just one year after its March 2024 launch.
This explosive growth underscores a broader shift: institutional investors are increasingly embracing blockchain-based financial instruments. Even amid a sluggish crypto market, RWA tokenization continues to gain momentum, with total market AUM climbing 18.29% in the past 30 days to reach $19.23 billion.
BlackRock’s BUIDL Dominates the RWA Landscape
According to data from RWA.xyz, BlackRock’s BUIDL has seen its AUM grow by nearly 129% over the last month alone, making it the largest tokenized asset by market capitalization. This rapid ascent highlights growing confidence in blockchain’s ability to modernize traditional finance.
Launched on the Securitize platform, BUIDL offers investors exposure to short-term U.S. Treasury securities through a blockchain-native structure. The fund’s success reflects strong demand for secure, yield-generating digital assets backed by tangible financial instruments.

Blockchain Distribution: Ethereum Leads the Way
Despite expanding across multiple blockchains—including Avalanche, Aptos, Polygon, Arbitrum, and Optimism—Ethereum remains the dominant network for BUIDL. Over 86.46% of the supply, valued at more than $1 billion, is minted on Ethereum.
This concentration signals robust institutional activity on Ethereum, reinforcing its position as the leading public blockchain for compliant, regulated financial products.
Smaller portions of the fund are distributed across other chains:
- Avalanche and Aptos: ~$56 million each (~3.6%)
- Polygon, Arbitrum, Optimism: Host the remaining fractional allocations
The multi-chain strategy enhances accessibility and scalability while maintaining regulatory compliance—a critical balance for global asset managers like BlackRock.
Growing Investor Participation
Beyond asset growth, investor adoption is also rising. The number of unique holders has increased by 19% in the past month, now totaling 62 institutional and accredited investors.
While this number may seem modest compared to retail crypto projects, it reflects the highly regulated nature of tokenized securities. Each participant must undergo rigorous Know Your Customer (KYC) and anti-money laundering (AML) checks, ensuring compliance with U.S. securities laws.
Market analysts interpret this growth as a sign of deepening trust in blockchain-based finance and increasing institutional appetite for tokenizing bonds, credit, and money market instruments.
Fidelity Enters the Tokenization Arena
As BlackRock solidifies its lead, Fidelity Investments is stepping into the RWA race with plans to launch its own blockchain-based fund.
Last week, Fidelity filed with the U.S. Securities and Exchange Commission (SEC) to introduce an “OnChain” share class of its existing Treasury money market fund. This new class will use blockchain technology—specifically Ethereum—as the transfer agent and settlement layer.
“The OnChain class of the fund currently uses the Ethereum network as the public blockchain. In the future, the fund may use other public blockchain networks, subject to eligibility and other requirements,” the SEC filing states.
This move aligns with a growing trend among major financial institutions seeking to leverage blockchain for:
- Faster settlements: Near-instant transaction finality
- 24/7 operations: Eliminating traditional market hours
- Greater transparency: Immutable on-chain records
- Reduced counterparty risk: Smart contract automation
Fidelity’s entry validates the long-term potential of RWA tokenization and signals that more traditional finance (TradFi) giants are preparing to digitize their offerings.
The Broader Rise of Real-World Asset Tokenization
Despite Bitcoin’s year-to-date decline of 11%, RWA tokens have demonstrated resilience and consistent growth in 2025. The sector now boasts:
- $19.23 billion in total AUM
- Nearly 91,000 unique holders
- A 5% increase in holder count over the past month
Market Composition: Private Credit and Treasuries Lead
Within the RWA ecosystem, two asset classes dominate:
- Private credit: $12.2 billion (63.4% of total RWA AUM)
- U.S. Treasuries: $4.76 billion (24.8%)
These figures reflect investor preference for income-generating, low-volatility assets—especially in uncertain macroeconomic conditions.
Top Tokenized Assets by Market Cap
- BlackRock BUIDL: $1.4 billion
- Hashnote USDY: $784 million
- Tether Gold (XAUT): $752 million
These leaders illustrate the diversity of RWAs being tokenized—from government debt to precious metals—offering investors new ways to access traditional asset classes with digital efficiency.

Why Institutional Adoption Is Accelerating
Several factors are driving financial institutions toward tokenization:
1. Operational Efficiency
Blockchain reduces reliance on intermediaries, cutting settlement times from days to minutes and lowering operational costs.
2. Regulatory Clarity
Platforms like Securitize and partnerships with established custodians provide compliant frameworks that meet SEC and global regulatory standards.
3. Investor Demand
Institutional clients are demanding more transparent, liquid, and programmable investment vehicles—especially those offering stable yields in volatile markets.
4. Interoperability Across Chains
Multi-chain deployment allows funds like BUIDL to reach diverse ecosystems while maintaining security and compliance.
