BTCFi is a cross-network CDP system in which BTC-family collateral supports BtcUSD debt. Current documentation permits minting up to 50% of collateral value at a stated 5.5% loan rate and warns of liquidation; repayment is required before collateral withdrawal. DefiLlama measured $6.62M across Bitcoin, Bifrost Network, Base and CORE on 2026-08-16, not the former $67,000 Base-only snapshot. That is still just 6.62% of the size floor. The version-1 dossier therefore rejects BTCFi. We will not open the individual review until it clears the floor, so we have not yet decided whether cross-chain custody, oracle, liquidation and BtcUSD liquidity could support an advised allocation.

The research file

Mechanism and product perimeter

BTCFi accepts BTC-family assets from multiple networks, records collateral through its Bifrost-powered cross-chain system and lets a user mint BtcUSD. Official instructions cap minting at 50% of collateral value and state a 5.5% loan interest rate. This record covers the CDP collateral and BtcUSD debt claim. Optional BiFi deposits and Everdex LP positions are later products and are not treated as the same exposure.

Control and loss applicability

A borrower takes on Bitcoin-wrapper or native-BTC custody, cross-chain messaging, Bifrost contract, collateral valuation, stablecoin peg and liquidation risks. The documentation warns that reaching the liquidation threshold can liquidate collateral. In the reviewed pages, however, it does not give a complete current map of the oracle, keeper, administrator, insurance, bad debt or incidents for every supported network. The claim of decentralization does not replace those controls.

Current accounting and exit

DefiLlama reported $6,621,428 on 2026-08-16: most on Bitcoin and Bifrost Network, about $72,215 on Base and a residual balance on CORE. The API metric is collateral TVL, not BtcUSD market depth or cash available for immediate redemption. A borrower must acquire and repay BtcUSD plus interest, complete the cross-chain release path and then transfer or unwrap BTC. Downstream LP or lending positions add their own exit steps.

Comparison and measurable reopening test

Unlike a same-chain Maker-style vault, BTCFi adds Bitcoin and Bifrost cross-network settlement. Unlike holding BTC directly, the client takes on debt, stablecoin and liquidation risks. Size alone decides the result at 6.62% of the floor. Reopen after collateral TVL exceeds the size floor for 30 days. Then reconcile exact contracts, custody, messages, oracles, authorities, liquidation and bad-debt history, BtcUSD supply and liquidity, and a proposed-size repay-to-BTC exit.

Research status

This is a capacity-unproven record for BTCFi CDP, not a quality rejection or approval. Reported TVL says how big the venue is, not what the client owns, who can change the rules, or how a position exits at a proposed size. The individual review opens when the protocol clears the size floor.

Sources

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
