Coinbase、Baseネットワークでトークン化株式を発表

著者: DefiLiban·

重要ポイント

  • Coinbaseは、自社が構築したEthereumレイヤー2ネットワークBase上で、トークン化株式をトークン化プログラムを通じて直接清算する形で開始した。
  • これらのトークンは24時間の移転可能性とほぼ即時のオンチェーン清算を提供し、2024年5月に米国株式が採用したT+1サイクルと対比される。
  • Baseでの清算により、株式トークンはネットワークのスマートコントラクト環境に組み込まれ、開発者はLayer 2を離れずに株式担保を中心としたプロダクトを構築できる。
  • 今回の発表は、Ether.fiのトークン化株式提供やBlackRockの2024年BUIDLトークン化マネー・マーケット・ファンドを含む、オンチェーン資産への業界全体の移行を反映している。
  • 採用は、2025年のSECクリプト・タスクフォースによるトークン化を巡るラウンドテーブルにもかかわらず不透明な米国の法的扱いと、Baseのブリッジおよびコントラクトのセキュリティリスクによって制約されている。
Coinbase、Baseネットワークでトークン化株式を発表

Coinbase has debuted tokenized stocks on Base, its Ethereum Layer 2 network, extending real-world equity exposure directly onto on-chain rails through the exchange's tokenization program. The move positions Base as the distribution and settlement venue for equity tokens rather than routing users to an off-chain brokerage feed, opening the tokens to on-chain access for wallets and applications on the network.

What Coinbase Launched on Base

Tokenized stocks are blockchain-based representations of equity exposure, letting a share of a listed company be held and transferred as an on-chain token instead of a conventional brokerage entry. The category's appeal rests on round-the-clock transferability and near-instant on-chain settlement, in contrast with conventional U.S. equity settlement, which moved from T+2 to T+1 only in May 2024. Coinbase, one of the largest cryptocurrency exchanges in the United States and itself a Nasdaq-listed company, is conducting the debut through its tokenization program.

The rollout counts as a product launch rather than a user-interface tweak, because the equity exposure settles on Base itself. That places the assets inside the same smart-contract environment as the network's DeFi stack, rather than inside a walled brokerage ledger. For related coverage, see Ether.fi Adds Tokenized Stocks, Metals and Aave-Powered Portfolio Loans. Separately, the Compound Foundation has tapped Coinbase and Anchorage alumni for a $52M institutional credit push.

The framing mirrors a broader push by exchange-linked issuers to move equities on-chain. Ether.fi, for example, has wired tokenized stocks into fiat rails and Aave-powered borrowing, signaling demand for equity tokens that plug directly into money markets. Traditional asset managers have been moving the same direction from the cash side of the balance sheet — BlackRock's BUIDL fund, launched in 2024, put tokenized money-market exposure on-chain — and equity tokens extend that pipeline from cash instruments to stocks.

Why Base Is Central to the Rollout

Base is the Ethereum Layer 2 network built by Coinbase; Layer 2 chains batch transactions off Ethereum's mainnet and settle them back to it, cutting fees while leaning on Ethereum as the settlement layer. Its selection as the venue changes the framing of this launch from a closed brokerage feature to a composable on-chain asset. Base's positioning among Ethereum scaling networks, where it has ranked among the largest by total value locked, is independently tracked on L2BEAT.

What On-Chain Availability Means for Users and Developers

Settling equity tokens on Base means they can, in principle, interact with the network's contracts, wallets, and applications rather than remaining siloed. For developers, that opens the door to building products around equity collateral without leaving the Layer 2 environment.

Base has also become a magnet for real-world-asset experimentation, a trend visible as rival venues compete for the same flow. Robinhood's own network saw TVL climb even as tokenized RWAs lost ground, underscoring how contested on-chain equity distribution has become.

What the Launch Could Mean for Tokenized Equities

Tokenized stocks act as a bridge between traditional equities and crypto rails, and a Coinbase-linked rollout on Base pushes that bridge onto one of the most active Layer 2 networks. That raises the competitive stakes for other issuers targeting on-chain equity access.

The category remains sensitive to compliance and market-structure questions, since equity tokens sit at the intersection of securities rules and on-chain settlement. In the United States, the SEC's crypto task force held a series of public roundtables during 2025, including one dedicated to asset tokenization, a period that coincided with a run of tokenized-equity pilots from crypto-native venues — even as the legal treatment of equity tokens itself remains unsettled. How the tokens are wrapped and where they can be traded will shape adoption more than throughput alone.

For Base specifically, absorbing equity tokens adds a real-world-asset dimension on top of its existing DeFi activity, though the launch also inherits the network's operational risk surface. Bridge and contract exposure remain live concerns, a point underlined by incidents such as The Sandbox halting Base bridging following an exploit.
