Granite Protocol has gone live on Borrow on Bitcoin, a dedicated platform for Bitcoin-based decentralized finance lending. The launch, which took effect this week, marks another step in the push to build DeFi infrastructure directly on top of Bitcoin rather than on sidechains or alternative layer-1 networks.
What Borrow on Bitcoin offers
Borrow on Bitcoin is a lending marketplace that lets users deposit Bitcoin and borrow against it — or lend their BTC to earn yield. Granite Protocol is the latest lending protocol to join the platform. The idea is to keep everything settled on Bitcoin's main chain, avoiding the bridge risks and liquidity fragmentation that have plagued cross-chain DeFi.
Why Bitcoin DeFi is gaining traction
Proponents of Bitcoin DeFi argue that it can offer lower borrowing rates because the underlying asset — Bitcoin — is more stable in terms of liquidity and market depth than many altcoins used in traditional DeFi. There's also a focus on reducing systemic risks. Traditional DeFi protocols often rely on complex tokenomics and governance tokens that can introduce fragility. By building on Bitcoin, Granite Protocol and similar projects aim to strip away some of that complexity.
What this means for users
For now, the Granite Protocol launch gives Bitcoin holders another way to put their assets to work without selling. Users can supply BTC to the protocol's lending pools and earn interest, or borrow against their Bitcoin at what the team describes as competitive rates. The protocol is live and accepting deposits as of this week.
The timing isn't accidental. Bitcoin DeFi has been quietly growing through 2026, with several protocols launching on platforms like Borrow on Bitcoin. The idea is to offer a simpler, more secure alternative to the Ethereum-based DeFi that dominated the last cycle.
Whether Granite Protocol can attract meaningful liquidity remains to be seen — but the launch itself signals that builders are still betting on Bitcoin as the foundation for the next wave of decentralized lending.
