Bivium
Bivium turns your wallet into its own lending venue. You set the rate, you pick the collateral, and people borrow from you not from an anonymous pool. Built on EIP-7702, every wallet is a resting limit order. When risk shows up, it stays with the lender who signed it.

Bivium is what happens when you take the lending pool out of DeFi lending.
Three weeks ago, Aave lost fifteen billion dollars of TVL in three and a half days. The contracts didn't fail — they worked exactly as designed. An attacker minted unbacked rsETH, used it as collateral, and borrowed real WETH against it. The people who lost money weren't the ones who chose to bet on rsETH. They were WETH depositors who just wanted yield. Governance had put them in that trade, quietly, months earlier.
That's the flaw we built Bivium to fix. In a shared pool, your risk is never really your decision. Some committee, some snapshot vote, some risk parameter set by a DAO — that's what decides what your money is exposed to. You just deposit and hope.
So we did the opposite. In Bivium, your wallet IS the protocol. One EIP-7702 delegation makes your existing wallet programmable — same address, same history, your funds never move. From that moment on, your own account becomes a single-lender venue. You sign the rate. You sign the collateral. You sign the terms. Nobody else.
And once every lender lives in their own wallet, lending stops being a pool and becomes an orderbook. Every wallet is a resting limit order — priced by its rate, sized by its balance. When a borrower wants liquidity, their market order walks the book and fills across many lenders at once, atomically. You don't borrow from "the protocol." You borrow from jesus.eth, cobie.eth, and vitalik.eth — at whatever blended rate the book gives you in that block.
The consequence is the part that matters: when the next rsETH happens — and it will — the loss stays with the lenders who signed that exposure. Not with bystanders. Pooled lending socializes risk. Bivium individualizes it.
The timing isn't an accident either. This primitive simply didn't exist until EIP-7702 shipped. It's live on Arbitrum today. ERC-7715 lets borrowers pre-sign intents on top. Underneath, we use a Morpho-style lending engine for the actual mechanics — proven, audited math, just with a very different shape on top.
No pool. No governance. No anonymous counterparties. Your exposure is your signature, and only yours.
