As the only BTCFi project led by Founders Fund, @citrea_xyz has finally reached its mainnet moment after a long testnet phase, yet it’s barely being talked about. I’ve always been openly bearish on the BTCFi sector. The main reason is that during the early BTCFi hype, almost all BTC L2 chains were launched using OP Stack and other RaaS chain-launching tools, essentially just Ethereum L2 chains dressed up as BTCFi, with no real technical innovation. Citrea leverages zero-knowledge proof technology and BitVM to use Bitcoin as a data availability and settlement layer, shifting complex computation execution off-chain while verifying execution results on-chain. This is @citrea_xyz’s core technical innovation compared to other Bitcoin L2s, but due to the high difficulty of implementation, it’s only recently gone live on mainnet. To me, Citrea is a rare project driven by dual technical resources. The project itself is solid; now it’s up to Citrea’s operational strategies and ability to make waves. I dug into Citrea’s mainnet data: after 17 days, there are only 7,000+ addresses. The official dashboard activities launched alongside the mainnet aren’t overly competitive. After evaluating, I’ve decided to give it a try. The gameplay is similar to other public chain mainnet activities: cross-chain fund retention, providing liquidity, trading, lending, yield aggregation, etc. Dyor.
