Dolomite adds $100 million in Concrete Bitcoin-backed collateral

Dolomite has added $100 million in Bitcoin-backed collateral from Concrete, letting users borrow against BTC held in BitGo custody. Unlike typical onchain lending, liquidations settle through offchain custody rather than an instant onchain sale. The deal expands Bitcoin-backed credit capacity in DeFi, though the offchain liquidation model introduces custody and settlement risk traders should weigh.
