Citrus Bitcoin ZK Rollup mainnet goes live, launching native stablecoin ctUSD

On January 29th, the Bitcoin ZK rollup project Citrea, invested by Founders Fund and Galaxy Ventures, was officially launched on the mainnet, launching DeFi lending, structured products, and native USD stablecoin ctUSD with BTC as collateral. Citroa stated that the initial active DeFi liquidity on the mainnet is expected to reach $50 million. CtUSD is issued by MoonPay, with 1:1 anchoring of cash and short-term US bonds, and is originally issued on Citroa to reduce bridging risks and avoid liquidity fragmentation. During the testing phase, data shows that Citroa's data availability usage once accounted for nearly 10% of Bitcoin's monthly data bandwidth, and Rollup may have an impact on Bitcoin's block space.
