We secured $5B of DeFi. Then we built the proof.

We founded Chainrisk and ran economic security for Compound Finance, Polynomial and Arbitrum: $5B+ without a single economic exploit. AFI applies the same discipline to the other side of the balance sheet, verifying that tokenized assets are solvent, every hour, on-chain.

The story

Six years, connected backwards.

“You can't connect the dots looking forward; you can only connect them looking backwards.”

Steve Jobs · Stanford, 2005

$1.5B verified. Every hour.

Multipli and Spectra live. $225M in vaults that only accept what's proven. Six years in, we're still asking the same question. Now we can answer it.

8,760 proofs a year

Then the world started tokenizing.

Treasuries, gold, credit, all moving on-chain, and our clients kept asking the one thing we couldn't simulate: is the collateral actually there, right now? So we built AFI to answer it.

Compound Finance trusted us with their economics.

Six million scenarios against Compound Finance on Arbitrum. Then Polynomial, Angle, Superlend. Five billion dollars sat under our models and none of it was lost to an economic exploit.

$5B+ secured, zero exploits

The code held. The economics didn't.

We went back through every major DeFi loss. Most weren't hacks. Nobody was simulating market stress before it hit, so we built Chainrisk to do exactly that. Antler backed us early.

55% of losses were economic

Twenty audits, mostly for free.

Arka finished the Polygon fellowship and we started auditing contracts together. ETHIndia gave us a grant; we did twenty. Every single time the code was fine and something else wasn't.

20 audits, first grant

It started with a bug.

Sudipan found one in Netflix from his dorm at IIT BHU and got paid for it. Small cheque. Big realisation: the largest systems in the world had gaps nobody was watching.

A note from the founders

Evidence over assurance.

Tokenized treasuries, gold and credit are moving on-chain in tens of billions, stablecoin law is being written in Washington, Brussels and Abu Dhabi, and DeFi's largest lenders now take these tokens as collateral. Almost all of them are still verified the old way: a quarterly attestation and a promise the reserves were there on the day someone looked.

We know this gap from the inside. Three years securing $5 billion of DeFi at Chainrisk taught us one thing: contracts hold, losses come from what the code cannot see. With tokenized assets, that blind spot now sits off-chain, in statements that settle monthly while the token trades every second.

So verification has to move at the speed of settlement, and it has to be enforced, not published. AFI proves assets against liabilities every hour, on-chain, without exposing a position — and the proof itself decides what can be minted and what a vault will accept.

Our standard is simple. If it cannot be proven, it should not be relied upon.

Mission

Make solvency a live property of every tokenized asset, proven every hour, on-chain, without exposing a single position.

Vision

A market where nothing is allocated to what cannot be verified.
