Getting paid to borrow money sounds like a financial fever dream. Sats Terminal just made it real on Starknet.

The BTC lending platform announced its integration with Starknet on July 22, enabling users to borrow USDC against their Bitcoin collateral through the Vesu lending protocol at a net APR of approximately -2.04% at a 50% loan-to-value ratio. In English: borrowers walk away with more money than they owe in interest, courtesy of STRK token rewards that more than cover the borrowing costs.

How negative interest actually works

Negative APRs aren’t magic. They’re subsidized. Starknet has allocated at least 100 million STRK tokens toward its rewards program, and those incentives are what make the economics work for borrowers.

Here’s the math on a concrete example. A borrower putting up 1 BTC as collateral can expect to earn roughly $1,997 annually from STRK rewards while paying approximately $1,344 in interest. That nets out to about $653 in the borrower’s pocket, just for taking out a loan.

The maximum loan-to-value ratio through Vesu can stretch up to 86%, though the juiciest negative rates come at the more conservative 50% LTV tier.

The integration runs through Vesu, a lending protocol on Starknet that positions itself as capital-efficient. Sats Terminal acts as the front-end interface, connecting Bitcoin holders to USDC liquidity without requiring them to sell their underlying BTC position. The loans are non-custodial, meaning users maintain control of their assets throughout the process.

Sats Terminal’s growing footprint

The platform has onboarded over 100,000 unique wallets since its inception. Its backers include yzilabs, Coinbase Ventures, and Draper VC. Tim Draper himself highlighted the platform back in January 2026.

Co-founder Stanislav Havryliuk and his team have been building toward this kind of cross-chain integration. Moving onto Starknet, a ZK-rollup scaling solution originally designed for Ethereum, represents a bet that Bitcoin-native users want access to DeFi infrastructure beyond the Bitcoin network itself.

What this means for investors

Negative rates funded by token rewards only work as long as the reward tokens maintain their value and the incentive programs keep running. STRK rewards that generate $1,997 annually today could generate significantly less if the token price drops or if Starknet decides to redirect those 100 million tokens elsewhere.

The 86% maximum LTV deserves attention from a risk perspective. High LTV ratios in volatile markets can lead to cascading liquidations. Conservative borrowers sticking to the 50% tier have meaningful buffer. Those pushing toward the ceiling are betting that Bitcoin’s price won’t move against them fast enough to trigger a margin call.
