Onchain finance challenges Wall Street as tokenized assets cross $17B

Tokenized US funds have reached roughly $14.2B onchain, according to Allium’s Q2 2026 report. Tokenized equities have hit $3.3B in the same timeframe. Combined, that’s over $17B in traditional financial instruments living natively on blockchains.

What onchain finance actually means

The term “onchain finance,” sometimes shortened to OnFi, draws a deliberate line between itself and the earlier DeFi wave. Where DeFi circa 2020-2022 was largely permissionless and experimental, onchain finance builds compliance into the architecture. Think KYC, AML, and institutional-grade custody baked into smart contracts rather than bolted on as an afterthought.

A tokenized US Treasury fund operating onchain can settle atomically, meaning the trade and the payment happen simultaneously rather than waiting the standard T+1 settlement cycle. It can trade around the clock, not just during New York market hours.

Andre Cronje, the developer behind Yearn Finance and other DeFi protocols, articulated this evolution in August 2026. He framed the shift as one from DeFi’s emphasis on disintermediation toward onchain finance’s focus on operational efficiency and compliance.

The SEC opens a door

The most consequential development came on September 17, 2026, when the SEC issued a time-limited exemption allowing automated trading of listed US stocks through tokenized securities venues, or TSVs. These venues use automated market makers to facilitate trades in National Market System stocks, but settled onchain.

On nearly the same day, S&P Global announced its acquisition of OpenZeppelin, the blockchain security firm best known for its smart contract libraries and auditing services.

The institutional land grab

BlackRock has been tokenizing fund products. Franklin Templeton launched one of the first tokenized US government money market funds. JPMorgan has been building blockchain-based settlement infrastructure for years through its Onyx platform. State Street, Fidelity, and Citi are all exploring various tokenization strategies.

Ondo Finance has emerged as a particularly notable player in the real-world asset tokenization market, building infrastructure that bridges traditional fixed-income products with blockchain settlement.

Real risks under the optimism

Custody remains a thorny issue. When a tokenized equity settles onchain, what exactly does the buyer own? The token itself, or a claim on the underlying share held by a custodian? The legal frameworks governing these questions vary by jurisdiction and remain largely untested in court.

Smart contracts can eliminate certain intermediaries, but they introduce new dependencies: the security of the contract code, the reliability of the oracle feeding price data, the governance of the protocol itself.

Tokenized assets currently live across multiple blockchains, each with different technical standards, liquidity pools, and regulatory treatment. A tokenized Treasury on Ethereum and one on Solana might represent the same economic exposure but trade in entirely separate markets.
