Bitlayer (BTR) is a Bitcoin Layer-2 network that uses BitVM technology and a rollup architecture to deliver Bitcoin-level security while enabling scalable DeFi applications. Built with a dual-layer Proof-of-Stake (PoS) design, it features an Execution Layer for sub-second transaction finality and a Settlement Layer that finalizes data on the Bitcoin main chain. Its $BTR token, sold via CoinList in July–August 2025 at $0.15–$0.20, raised about $4M (with an FDV near $300M) and is used for staking, governance voting, and fee mechanisms within the ecosystem @BitlayerLabs #Bitlayer
