BTCfi has arrived on Starknet, giving Bitcoin holders new ways to earn yield and explore opportunities in DeFi. With Rhino.fi, you can seamlessly bridge wBTC from Ethereum, Base, BNB and Arbitrum with zero bridging fees and put your Bitcoin to work.

Rhino.fi was the very first StarkWare client and has supported Starknet since day one.

How to earn yield with BTC on Starknet

Once your BTC is bridged into Starknet via Rhino.fi, you can put it to work across a growing set of protocols:

• Staking: Stake BTC through validator-backed mechanisms that secure the network, creating sustainable yield tied to real demand for blockspace.

  
  

• Lending: Supply BTC into lending markets to earn interest from borrowers. Current participating money markets include Vesu and Opus, supporting assets such as LBTC, SolvBTC, TBTC and WBTC as supplied collateral, with the ability to borrow USDC, USDT, CASH and soon USDA/USDU.

  
  

• Liquidity provision: Provide BTC liquidity in DeFi pools to earn fees and potential rewards. Eligible pairs during BTCfi Season include WBTC/LBTC, WBTC/SolvBTC, WBTC/TBTC, XLBTC/LBTC, XSolvBTC/SolvBTC, XBTC/TBTC and XWBTC/WBTC. Supported DEX partners include Ekubo and Spline.

Sustainable BTC staking

Many yield systems rely on short term incentives. On Starknet, BTC staking is backed by validators who secure the network with real economic value at stake. This ensures yields are sustainable and tied to genuine demand for blockspace, not temporary rewards.

What’s next: Earn from 100M STRK in ecosystem rewards

BTCfi Season has been live since September 30, 2025, backed by 100M STRK in ecosystem incentives. Rewards are rolling out across participating protocols listed on the BTCfi Season site.
