Score history
This rating is re-checked every month. A point is recorded for every check, so a flat line means we looked and nothing moved. Hover anywhere on the chart to see what moved that month, and by how much.
The Problem
Bitcoin holders and stablecoin savers lack access to institutional-grade basis-trading yield without surrendering custody to a single CEX; existing stablecoin vaults offer no tranched risk options or insurance buffer.
The Solution
BitFi mints bfBTC and bfUSD against deposited BTC/USDT/USDC and routes collateral to Ceffu MirrorX for delta-neutral basis trading. bfUSD holders pick between a low-risk Horizon vault and a higher-yield Pulsar vault, with Pulsar acting as a loss-absorbing buffer for Horizon.
Why it Matters
Tranched stablecoin vault design (Horizon vs Pulsar) layered on top of CeFi basis trading, plus a BTC-native variant deployed across 7+ chains. Custodial backing via Ceffu MirrorX rather than self-custody. Audited by SlowMist (bfBTC 2024-12, bfUSD 2025-12).
