a16z crypto says Wall Street uses blockchain less for ideology than for efficiency, risk management and programmable market infrastructure that makes assets composable.
Guy Wuollet, general partner of a16z crypto, says the financial sector is undergoing a digital migration in which blockchain becomes the core infrastructure, just as cloud computing became the backbone of modern enterprise software. In his essay, Wuollet argues that “digital assets” are not primarily about ideology or decentralization, but about upgrading the financial architecture itself.
“Wall Street is beginning to adopt blockchains with fervor: not because it is fixated on the idea of decentralization, but because blockchains create a Schelling point between counterparties to upgrade existing backend systems,” Wuollet wrote. He added that “digital assets” “represent digital transformation for financial services in the same way that cloud services once represented digital transformation for large enterprises.”
The argument is blunt and basically correct. Traditional finance still runs on fragmented databases, lagged reconciliations and institution-specific ledgers, so the appeal of blockchain lies not in philosophical purity, but in a shared infrastructure that can improve settlement, ordering and coordination between companies.
From closed ledgers to shared infrastructure
Wuollet argues that most of the financial world is not truly digital in the sense of modern software, because assets still move through siled systems that require constant coordination between counterparties. Blockchains, on the other hand, provide a common, programmable infrastructure where multiple institutions can coordinate based on a single source of truth, reducing operational complexity and counterparty exposure.
That shift, in the context of a16z, is important because it changes what financial products are made of. “What follows when financial assets live on a shared, programmable infrastructure is that they can be combined, expanded and integrated without building everything from scratch,” wrote Wuollet, who described composability as crypto’s “greatest superpower.”
In practical terms, composability means that tokenized assets can be used as software building blocks. Rather than forcing every bank, broker or exchange to build siled products and custom integrations, shared blockchain rails could allow developers and institutions to combine the functions of custody, settlement, collateral, lending and trading more cheaply and quickly.
Wall Street’s on-chain logic
a16z has been pushing this case more aggressively as traditional financial companies accelerate their tokenization efforts. In a separate April essay, the company wrote that “Wall Street isn’t just exploring blockchain anymore. It’s migrating to it,” pointing to exchanges, clearinghouses and electronic trading platforms that are moving on-chain to lower costs and shorten settlement cycles.
This vision is in line with recent developments across Europe and US Börse Stuttgart’s Seturion platform is being developed as a blockchain-based settlement layer for tokenized securities, while Société Générale-FORGE is providing regulated stablecoins such as EURCV and USDCV to support on-chain settlement. The same institutional logic is also evident in products like Bitwise’s Hyperliquid ETF and the broader expansion of tokenized financial infrastructure beyond bitcoin and ether.
The deeper point in Wuollet’s essay is that the financial sector is developing from a closed reconciliation model to a coordination model within the chain. That’s a structural change, not a branding exercise, and if it turns out as a16z expects, blockchain will no longer be treated as an alternative financial system and be absorbed as a standard layer of financial infrastructure.
This statement is also reflected in the recent crypto.news reporting on tokenized securities, on-chain settlement, and institutions’ broader push for digital asset infrastructure.
