Bitlayer connects Sui, Solana, and Base, plans to integrate Polygon and Avalanche by 2026, with a TVL of 200 million USD in 2025, but does the multi-chain layout lead to ecological fragmentation? Users generate YBTC to participate in @MMTFinance lending, with returns of 6-10%, or Arbitrum's derivative trading, with trading volume increasing by 40%. BitVM2 and F2Pool ensure verification efficiency at 99.9%, with fees below 5 USD. The community is concerned that increased multi-chain complexity raises governance difficulties, with two cross-chain delay incidents in 2025 causing controversy. Bitlayer optimizes the protocol through BTR governance, with a proposal approval rate of 80%, and the 'Booster' activity rewards 5.15 million BTR, increasing active addresses by 118%. The 25 million USD funding in 2024 supports new chain integration, but the risk of ecological fragmentation remains. The BTCFI Carnival prize pool of 1.2 million USD attracts 100,000 users but has been accused of covering up technical challenges. @BitlayerLabs yer needs to balance multi-chain expansion with ecological unity; the success of YBTC promotes BTCFi, but long-term risks of fragmentation must be heeded. #Bitlayer
