Coinbase Launched a Tokenized Bitcoin Fund on Base – BlackRock and Fidelity Are Building the Same Stack From Different Angles

Coinbase Asset Management launched a tokenized share class of its Bitcoin Yield Fund on Base on March 19, using the ERC-3643 compliance standard in partnership with Apex Group and Tokeny, as BlackRock and Fidelity simultaneously advance competing institutional blockchain fund infrastructure across multiple chains and product categories.

What Coinbase Launched and How It Works

According to official press release from Apex, the tokenized share class operates on Base, Coinbase’s Ethereum Layer 2 network, and uses the ERC-3643 permissioned token standard to embed compliance, identity verification, and investor eligibility rules directly into the smart contract. As covered in earlier reporting this week, ERC-3643 ensures transfers only execute when both sender and receiver meet the regulatory criteria stored on-chain, removing the need for external compliance checks at the point of transaction.

The fund is currently available to institutional and accredited investors outside the United States. Coinbase Asset Management manages the investment strategy. Apex Group serves as transfer agent, maintaining ownership records and synchronizing them with the fund’s net asset value. Tokeny powers the onboarding portal that verifies on-chain identities before access is granted.

The Bitcoin Yield Fund targets net returns of 4% to 8% in BTC per year through conservative yield strategies, providing institutional Bitcoin exposure with an on-chain distribution layer that enables lower settlement costs, faster transaction processing, and 24-hour trading availability compared to traditional fund infrastructure. Coinbase has stated plans to launch a similar tokenized share class for its U.S. Bitcoin Yield Fund at a future date.

BlackRock’s Infrastructure-First Approach

BlackRock has moved furthest along the institutional tokenization path by treating blockchain as primary infrastructure rather than an additional distribution channel. The BlackRock USD Institutional Digital Liquidity Fund, known as BUIDL, reached $2 billion in assets by early 2026 after expanding from its original Ethereum deployment to Aptos, Arbitrum, Avalanche, BNB Chain, Optimism, and Polygon. That multi-chain architecture maximizes institutional accessibility by meeting counterparties on whichever chain they already operate on rather than requiring migration.

The firm’s DeFi integration goes further than most traditional asset managers have gone. BlackRock integrated BUIDL into UniswapX and acquired UNI governance tokens, giving it a direct stake in Uniswap’s protocol governance. That move is structurally significant. A $10 trillion asset manager holding governance tokens in a decentralized exchange is not a passive investment. It is a seat at the table in decisions about how the protocol evolves.

On March 12, BlackRock launched the iShares Staked Ethereum Trust, its first ETF structured to distribute monthly cash dividends from staking rewards. That product converts staking yield into a familiar dividend-paying equity wrapper for investors who want ETH exposure with cash flow rather than token accumulation.

Fidelity’s Competing Stack

Fidelity entered crypto infrastructure in 2018 and has built a diversified product set rather than concentrating on a single flagship fund. Its tokenized Treasury bill fund competes directly with BUIDL for institutional on-chain yield-bearing asset flows. Beyond that, Fidelity operates spot Bitcoin through FBTC, spot Ethereum through FETH, and spot Solana through FSOL, covering the three largest digital assets across brokerage, trust, and IRA account structures.

Fidelity’s 2026 research frames the institutional adoption trajectory in sovereign terms. The firm notes that countries including Brazil have begun legislating Bitcoin into their national reserve structures, extending the institutional adoption argument from asset managers and corporations into the sovereign wealth category.

What the Three Launches Together Represent

Coinbase, BlackRock, and Fidelity are building the same product category from different starting positions. Coinbase is extending its exchange and custody infrastructure into asset management. BlackRock is extending its fund manufacturing capability into blockchain native distribution and DeFi governance. Fidelity is extending its retail and institutional brokerage reach into on-chain yield products across multiple assets.

The competitive outcome of that three-way build is not yet determined. BlackRock’s BUIDL at $2 billion in AUM leads on institutional tokenized fund scale. Fidelity’s multi-asset ETF suite leads on retail accessibility and account type coverage. Coinbase’s Base deployment leads on native blockchain infrastructure integration. Each firm is winning a different dimension of the same market simultaneously.

As the tokenized government debt market surpasses $1.8 billion and institutional RWA infrastructure expands across Ethereum, Base, Polygon, and multiple other chains, the question is no longer whether traditional finance will tokenize its products. It is which infrastructure layer and which distribution relationship will capture the majority of assets when the transition reaches scale.
