a16z Crypto says TradFi is adopting blockchain tools, not DeFi

ARK Invest and Sentora disputed a16z’s view, arguing public blockchains and DeFi-based infrastructure may outperform permissioned institutional systems as banks and asset managers expand tokenization and blockchain settlement tools.

Fact Check
The primary a16z essay ('TradFi doesn't want DeFi. It wants blockchains.') explicitly presents the thesis that TradFi adopts blockchain tools/primitives while preserving permissioned institutional control—matching the claim's first part. Lorenzo Valente's X post directly rebuts this on behalf of ARK Invest, arguing public blockchains and crypto-native infrastructure will prevail over walled-garden systems. Both Cointelegraph and crypto.news confirm Sentora co-founder Jesus Rodriguez also disputed the thesis, arguing institutions will adopt DeFi's underlying infrastructure with compliance/custody layers. Every element of the claim is corroborated by primary and multiple secondary sources.
Summary

a16z Crypto said traditional financial institutions are incorporating selected blockchain-based functions into existing market infrastructure rather than embracing decentralized finance as a whole, arguing that banks and asset managers favor lower costs, faster payments, improved capital efficiency and compliance-friendly control. In posts on X on July 15 and the following day, the debate widened as ARK Invest research director Lorenzo Valente and Sentora co-founder Jesus Rodriguez challenged that view. a16z said institutions are likely to build permissioned, institution-controlled programmable financial infrastructure using tools such as tokenization, programmable money, tokenized collateral and atomic settlement, while treating open, anonymous and irreversible DeFi markets as a separate but complementary system. Valente argued public blockchains such as Ethereum have already outpaced private blockchain efforts and said crypto-native firms including Circle and Coinbase are better positioned than incumbent financial institutions to build next-generation financial infrastructure, while Rodriguez said institutions may adopt DeFi infrastructure with added compliance, custody and enterprise controls.
