Bitcoin is becoming an active asset in the Decentralized Finance (DeFi) ecosystem. For a long time, it had been assumed that bitcoin was to be only a digital gold and nothing more. That is changing. As more bitcoin holders look for ways to earn yield, lending dApps built on Bitcoin and the Bitcoin Layer 2 networks that support it are gaining traction.
For years, bringing DeFi to Bitcoin was a challenge due to the network’s design. Unlike Ethereum, built with smart contract functionality from the start, Bitcoin’s scripting language is intentionally limited to prioritize security and decentralization. This made it difficult to build complex financial applications directly on Bitcoin without relying on centralized intermediaries.
However, advancements in Bitcoin Layer 2 solutions like Stacks and Rootstock (RSK) have changed the landscape. These technologies enable smart contract functionality and scalable transactions while still settling on Bitcoin’s secure base layer. As a result, DeFi on Bitcoin is now possible in a trust-minimized way, allowing users to lend, borrow, and earn yield without leaving the Bitcoin ecosystem.
Whether you want to put your bitcoin to work or access liquidity without selling, these five Bitcoin DeFi lending platforms are worth checking out.
Zest Protocol

Zest Protocol was developed and launched in 2022 to bridge the gap between bitcoin and DeFi, and it is growing into a platform that provides a robust lending infrastructure for bitcoin holders looking for ways to diversify within the ecosystem.
The protocol allows users to earn yield on their bitcoin or borrow against it. Operating entirely on-chain, Zest Protocol’s smart contracts ensure transparency and security while enabling institutional-grade lending pools.
Key Features:
