Web3 Senior Software Engineer (Rust) - Bitcoin DeFi

What is Bitcoin DeFi:

Bitcoin DeFi is about unlocking real utility for the world’s most trusted digital asset without ever compromising user control. For developers and innovators, this means finding a way to use Bitcoin in decentralized finance without forcing holders to hand their BTC to a third party. Until now, most attempts at Bitcoin DeFi have relied on “wrapped” tokens that essentially represent a promise – you send your BTC away and trust someone else to issue a proxy token on another chain. In all these custodial models, users effectively give up custody of their bitcoin to an intermediary in exchange for a tokenized representation. This status quo runs counter to Bitcoin’s core ethos of self-sovereignty and security.
