what's spark?
Spark is a DeFi protocol designed as an on-chain capital allocator that deploys stablecoin liquidity across DeFi, CeFi, and real-world assets to maximize yield for users. It operates through SparkLend, a lending and borrowing platform where users can deposit assets like USDC, USDT, PYUSD, and ETH to earn competitive interest rates, or borrow against collateral at stable rates. The protocol emphasizes transparency, user-first design, and efficient liquidity management, positioning itself to support the stablecoin supercycle by providing deep liquidity for issuers like PayPal's PYUSD. Spark integrates with ecosystems such as Sky (formerly MakerDAO) for assets like USDS and sDAI, and features a liquidity layer to ensure instant redemptions without slippage. Its native token, SPK, enables governance voting, staking for rewards, and platform security. With over $12.5 billion in TVL, Spark drives innovation in Bitcoin liquidity and improves UI/UX for token trading in the BTC ecosystem.
Spark launched tri-party lending in Q4 2025; USDT deposits reached $180 million.
