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 is the largest crypto asset but lacks native yield primitives and is illiquid across DeFi ecosystems — moving BTC and Bitcoin-native inscriptions (ARC20, BRC20) into EVM chains for productive use requires custodial bridges and wrapped tokens.
The Solution
UniRouter issues uBTC, a BTC liquid-staking derivative on B² Network, and operates a dual lock-and-mint bridge for BTC inscriptions into EVM ecosystems. A roadmapped 'RouterChain' L1 is intended to host validator staking and cross-chain message verification.
Why it Matters
Focus on Bitcoin inscription assets (ARC20/BRC20/Atomicals/Ordinals) rather than ERC20-style assets, and deep B² Network integration as the primary deployment chain. The differentiating RouterChain component is not yet live.
