Hi, it’s Marc. ✌️
In January 2026, Sidney Powell went on record with CoinDesk and said a high-profile on-chain credit default was coming. Three months later, Aave, one of the largest crypto lending platforms in the world, found itself sitting on up to $230M it might never get back, following the Kelp cascade. [Read CEO Notes]
Sid didn’t predict Aave specifically. But he understood why something like it was inevitable. He’s the co-founder and CEO of Maple Finance, one of the biggest DeFi protocols. Maple has done more than $21B in loans under its newer model, with zero credit losses on overcollateralized lending since 2023.
When I sat down with him, I wanted to understand two things: what actually went wrong at Aave, and why Maple had managed to avoid anything like it.
The answers turned out to be the same: DeFi is dead.
“My view was in saying DeFi is dead, that DeFi is this kind of niche product category with an insular community. That concept is dead... Over time, it won’t be referred to as DeFi. It’ll just be referred to as finance.”
How Maple survived 2022: 2022 was when the idea of crypto lending almost died. The big names, Celsius, BlockFi, and Genesis, all collapsed. They’d been making loans backed by promises and assumptions rather than real collateral in real custody. When prices fell, the collateral wasn’t there.
Most people looking at that wreckage concluded that crypto lending was done.
Maple concluded the opposite.
“Everybody was saying crypto lending was done. But we took the contrarian view that this is literally the oldest profession in finance, lending, and what are the odds it’s not going to be around in the next couple of years?”
They rebuilt around collateralized loans, kept the legal structures that most of DeFi ignores, and waited. The competitors never came back. Maple did.
By April 2026, it manages over $4B in assets. Monthly transfer volume is running at $9.6B. Active loans are at $2.4B, up 48% over 2025.
About Sidney: Sidney Powell grew up in Australia, worked in securitization at a major bank, then became Treasurer at a commercial fintech lender. He’s been involved in more than a billion dollars in corporate bond issuance. He co-founded Maple in 2019 with Joe Flanagan.
Under his leadership, the platform has facilitated more than $20B in total loan originations as of early 2026, with assets under management (AUM) reaching approximately $5B. Powell has positioned Maple as a key player in the "on-chain credit" sector, focusing on bringing high-grade institutional structures like automated margin calls and tri-party custody to the digital asset space.

Our biggest takeaways from this conversation:
1. The problem with crypto lending was never the crypto part
It was the lending part. Specifically, the parts that make lending work, who takes the first loss, what happens when collateral falls, and who you can go after if things go wrong, got skipped in the rush to make everything open and automatic.
Ignoring these questions is why Celsius collapsed, why BlockFi collapsed, and why Aave is now working through hundreds of millions in potential bad debt.
"More things can happen than will happen."
Sidney explained the gap of Aave: Aave is built to handle falling collateral. When the value of what you’ve deposited drops, automated systems kick in and start selling it before the loan goes underwater. The whole thing depends on having enough time to do that.
The Kelp DAO hack removed that time completely.
“The asset was worth $100 one minute, and then roughly $80 the next. So it bypassed the level at which it could have been liquidated without a loss.”
And because Aave doesn’t have contracts with its borrowers, anyone can deposit anything, no paperwork, there was nobody to go after once the damage was done.
What made it worse: because Aave is designed to run itself with no human override, other users could see what was happening and made rational decisions that made things worse. They pulled their own collateral. They borrowed more while they still could. The platform wasn’t hacked. It just worked exactly as designed, in a situation nobody had fully planned for.
“If I give you $100 of collateral and borrow $80 from you, if you default, I have a problem. I can either try and withdraw my surplus collateral from you, or I can try and borrow more from you. Ordinarily, if you’re having bad debt issues, you wouldn’t do that for me, but because Aave is an immutable protocol, users could do that.”
