- Botanix announced it is winding down operations, bluntly stating programmable Bitcoin "did not work" in the current market and timeline after pitching BTC DeFi, staking and zero-knowledge rollups.
- Bitcoin's onchain DeFi activity totals less than $5 billion in TVL against Ethereum's roughly $39 billion, per DefiLlama, despite BTC's market cap being four to five times larger.
- Babylon co-founder David Tse said many Bitcoin L2s are "trying to bootstrap a brand new economy"; Babylon instead routes BTC into Ethereum DeFi via Aave so holders don't give up custody.
- Citrea CEO Orkun Mahir Kılıç said Bitcoin L2s should focus on products "uniquely enabled by Bitcoin security and settlement" rather than competing with Solana or Ethereum on day one.
- Rootstock CEO Diego Gutierrez Zaldivar compared building an L2 ecosystem to "settling a new city," and said BTC-backed lending is gaining renewed traction as speculative hype fades.
- Rootstock holds about $101 million in TVL while Citrea has less than $1 million in stablecoin market cap, per DefiLlama data cited in the article.
Why it matters: With Bitcoin onchain DeFi stuck under $5B against Ethereum's $39B TVL — despite BTC's market cap being 4-5x larger — Botanix's exit crystallizes a narrowing of the Bitcoin L2 thesis. Surviving projects like Babylon and Rootstock are concentrating around BTC-backed lending and Bitcoin-native settlement, meaning BTC holders who want DeFi exposure without giving up custody now have fewer but more focused on-chain options.
