BlackRock, the world’s largest asset manager, is taking early steps toward bringing its flagship iShares exchange-traded funds (ETFs) onto blockchain networks. The firm is currently in talks with the U.S. Securities and Exchange Commission (SEC) about tokenizing its ETF lineup — a move that could eventually allow mainstream Wall Street funds to operate on on-chain infrastructure.
While the idea is gaining momentum, BlackRock CFO Martin Small cautioned that the timeline remains uncertain. According to Small, the process could take anywhere from three months to a year to materialize. That wide window reflects where the industry stands today: interest from major institutions is clearly growing, but the legal and technical frameworks for large-scale tokenization are still being worked out.
If approved, tokenized versions of iShares ETFs would represent traditional fund shares on a blockchain. These digital tokens could settle around the clock and be programmed to interact with decentralized finance (DeFi) protocols. In simple terms, ETFs that today trade only during market hours could become 24/7 assets that plug directly into crypto-native products such as on-chain lending, collateralized loans, and structured investment strategies.
Industry watchers see this as more than just another experiment with blockchain. Matt Hougan described the development as a potentially important driver for the next phase of the crypto market, calling it a “very positive” signal for layer-one blockchains and the broader DeFi ecosystem. From a builder’s perspective, having regulated, well-known financial products available as on-chain collateral could open the door to a new class of DeFi applications — ones backed by familiar assets rather than purely crypto-native tokens.
The news arrives during a softer period for digital asset markets. Bitcoin is trading near $69,520, down about 1.65% over the past 24 hours, with around $43.0 billion in spot trading volume and a daily range between roughly $66,300 and $70,000 across major exchanges. Ethereum is changing hands close to $1,953, off about 2.5% over the same period, with nearly $19.5 billion in turnover as traders remain cautious following recent volatility in altcoins. Solana has seen steeper losses, trading around $82.14 after dropping roughly 5.5% in the last 24 hours, with about $3.5 billion in volume and a market capitalization near $47 billion.
Even with prices under pressure, BlackRock’s discussions with regulators highlight a longer-term shift underway. Crypto markets have often moved in line with broader macro risk sentiment, swinging sharply as investors adjust their appetite for risk. But the push to bring regulated, yield-bearing assets like ETFs onto public blockchains points to a different kind of growth story — one less driven by hype cycles and more by the integration of traditional finance with on-chain infrastructure.
If BlackRock follows through, tokenized ETFs could mark a meaningful step toward bridging Wall Street and DeFi, potentially reshaping how mainstream investors interact with blockchain-based markets in the years ahead.
