On March 28, the decentralized lending agreement Dolomite (TVL approximately US$800 million) announced that it would expand to the Bitcoin network through integration with Spiderchain developed by Botanix Labs. Spiderchain is a Bitcoin-based Layer 2 solution that uses a proprietary Proof-of-Stake (PoS) consensus mechanism and transforms Bitcoin from the UTXO model to an Ethereum-like account model to support smart contracts. Dolomite has previously run on multiple Ethereum-compatible networks, including Polygon zkEVM, Arbitrum, Berachain and OKX's X Layer. Notably, Trump-backed World Liberty Financial appointed Dolomite co-founder Caplan as the project's director of technology strategy. Spiderchain adopts a "decentralized multi-signature network" mechanism, manages Bitcoin mortgages through Botanix Orchestrators, and generates multi-signature wallets for consensus.
