What is DeFi?
DeFi
Decentralized finance (DeFi) is a category of financial services built on public blockchain networks, primarily Ethereum, that operates through self-executing smart contracts rather than centralized intermediaries. The material tracks debates over its security, regulatory standing, and institutional role.
How it developed
- May 2026 - Chris Berniski stated that over 96% of DeFi losses were unrelated to code security, and less than 10% of issues were due to code bugs.
- May 2026 - Chris Berniski said he advised friends and family to exit all DeFi positions, including blue chips like MakerDAO and Compound, due to superhuman coding agents.
- Jun 2026 - Ron Hammond noted that industry participants believed DeFi was important and opposed bills that would benefit them but not DeFi.
- Jun 2026 - David Hoffman argued that when Morpho flips back-end financial infrastructure for major institutions, it represents strong DeFi, contrasting with weak DeFi like Bitcoin; he added that if only weak DeFi remains, Ethereum is overprovisioned.
- Aug 2026 - Jason Yanowitz said DeFi’s share of total volume continues to rise, attributing it more to a shrinking denominator than a growing numerator; he also noted that the volume on everything else is decreasing.
- Aug 2026 - An industry observer noted that major hacks are all opsec hacks, and that a conservative compounding strategy has been the winning approach.

Jack Sanford reported that over 96% of DeFi losses in April 2026 were unrelated to code security.

Less than 10% of DeFi issues in the past year were caused by code-based bugs, per Mark Zeller, meaning most DeFi risk is non-technical.

OpenZeppelin founder advises exiting all DeFi positions due to superhuman coding agents.
“I've been privately advising friends and family to exit all DeFi positions, including low-risk blue chips like a maker dowo and compound due to coding agents that are superhuman at.”Chris Berniski · 29 May 2026
Google's Gemini was used by DPRK IT workers to generate fake IDs during a fake DeFi company sting operation, raising questions about AI misuse for identity fraud.
“Some of the fake ID stuff was stamped through Google's Gemini.”Laura Shin · 14 Aug 2026
Laura Shin argues DeFi platforms have an ethical duty to stop users from making wildly harmful trades.
“I think ethically and I do mean ethically like you have a responsibility. I mean, you have a responsibility to prevent the user from doing something that's just like wildly insane.”Laura Shin · 7 Aug 2026
Real on-chain B2B borrowing rates run 8 to 12%, far above the 2 to 5% retail DeFi rates typically cited, making on-chain credit uncompetitive with TradFi for business lending.
“The true so when you package all that up the true borrow rate for like what I would call like business like B2B borrowing business lending is closer to 8 to 12%. On chain today not the 2 to 5% that you see in a stuff.”Jason Yanowitz · 10 Jul 2026
The OpenZeppelin founder is privately warning that superhuman AI coding agents pose existential risk to blue-chip DeFi protocols, including Maker, Aave, and Compound.
“I've been privately advising friends and family to exit all DeFi positions, including low-risk blue chips like a maker dowo and compound due to coding agents that are superhuman at.”Chris Berniski · 29 May 2026
Without staking yield, ETH functions as a carry-trade funding leg (like the Japanese yen), meaning it gets borrowed and sold rather than held productively, creating structural sell pressure on the asset.
“If there's no yield on it on DeFi, what it means is that it as an asset becomes a funding leg.”Ryan Sean Adams · 10 Aug 2026
Coinbase and major CEXs declined an opportunity to back legislation that would benefit centralized exchanges at DeFi's expense, choosing instead to support DeFi alongside the rest of the industry.
“There was a time where there's opportunity maybe to try to put their weight behind a bill that would benefit them but not benefit DeFi and them as well as many other folks in including pretty much everyone said like no we actually believe DeFi is important here.”Ron Hammond · 4 Jun 2026
