Citrea Bitcoin ZK-Rollup Mainnet Launches with ctUSD, BTC-Collateral DeFi
Citrea, a Bitcoin ZK-rollup backed by Founders Fund and Galaxy Ventures, launched its mainnet on Jan. 29 with active DeFi liquidity potentially reaching $50 million at launch, BlockBeats reports. The platform introduces BTC-collateralized lending, structured products and a native USD stablecoin, ctUSD, issued by MoonPay and 1:1 backed by cash and short-term U.S. Treasuries. ctUSD is natively minted on Citrea rather than bridged to reduce bridge risk and avoid liquidity fragmentation. During testing, Citrea data-availability usage once accounted for nearly 10% of Bitcoin monthly bandwidth.
