U Protocol

U Protocol builds around Bitcoin-denominated assets: its flagship uBTC is backed jointly by wstETH and BTC.b, minted on Arbitrum and carried to other EVM and non-EVM networks through LayerZero's OFT standard, so Bitcoin-priced assets can move across chains without relying on centralised wrappers. Minting and redemption are both computed from collateral value, with issuance capped by the collateral ratio.

The protocol also issues a stable asset U, anchored in a band between 1 and 1.1 dollars and held above the floor by the excess value of collateral plus arbitrage paths rather than a hard peg to a single currency. The U Bitcoin Thunder Network built on top is positioned as a Bitcoin finance layer three, placing clearing, lending and market making in a separate execution environment while settlement returns to Arbitrum. Assets compose into collateral, yield and hedging strategies.
