Bitcoin Layer-2 Closure Reignites Debate Over Native DeFi Viability
Botanix, a Bitcoin layer-2 scaling platform that processed 25 million transactions across 200,000 wallets, shut down in June after four years of operation, unable to sustain sufficient fee volume and user demand despite technical functionality and live applications.
The closure has crystallized a persistent structural problem: Bitcoin holders treat the asset as pristine collateral and monetary reserve, not as a platform for decentralized finance. According to a GoMining survey of 730 Bitcoin holders conducted in October 2025, 77% have never used a BTCFi platform. Only 3% have integrated BTCFi into their overall strategy.
Wrapped Bitcoin on Ethereum-based chains has decisively out-competed Bitcoin-native DeFi layers. An estimated $20 billion in BTC now circulates on EVM chains in wrapped form, representing 2% of total Bitcoin supply. Most productive Bitcoin in DeFi sits in wrapped BTC products on Ethereum, Base, Arbitrum, Polygon, Solana, and BNB Smart Chain, according to the fact pattern cited by multiple researchers.
Andre Dragosch, head of research Europe at Bitwise, attributed the broader dynamic to Bitcoin’s dual identity. “Bitcoin is winning decisively as a monetary asset and as pristine collateral, but the case for Bitcoin as a standalone DeFi execution layer was always structurally weaker than the narrative suggested,” Dragosch said.
Botanix required users to bridge Bitcoin into a tokenized version on a separate EVM-based chain to access DeFi, introducing additional bridge and smart contract assumptions. The platform’s closure statement cited Ethereum’s “huge infrastructure network and Lindy effect,” liquidity depth, user experience, and regulatory comfort as decisive competitive advantages.
Users who arrived at Botanix seeking yield treated Bitcoin as store-of-value collateral, engaging in passive buy-and-hold strategies rather than active borrowing, trading, or frequent fund movement. This passive posture mirrors broader Bitcoin holder behavior: institutional and retail participants increasingly view Bitcoin as reserve collateral rather than programmable utility.
Justin d’Anethan, head of research at Arctic Digital, framed the competitive reality plainly: “There is more liquidity and better yields on EVM or SVM native solutions than on BTC solutions, period.”
Total value locked across all Bitcoin DeFi protocols stands at $4.12 billion according to DefiLlama, a modest figure relative to Bitcoin’s $1.2 trillion market cap. Bitcoin L2s and sidechains account for a minority share of that activity by value, with Rootstock supporting roughly 40% of Bitcoin DeFi activity.
Not all observers accept the verdict that Bitcoin-native DeFi is structurally unviable. Diego Gutierrez Zaldivar, chief executive of RootstockLabs, disputes claims of absent demand for Bitcoin-backed lending and yield products, citing institutional flows of hundreds or thousands of BTC into Rootstock-based products over the past year.
Orkun Mahir Kılıç, co-founder of Chainway Labs, argues Botanix’s failure reflects a narrower problem: the attempt to clone EVM DeFi primitives onto Bitcoin. Chainway Labs is developing Citrea, a Bitcoin-anchored rollup using zero-knowledge proofs, as an alternative architecture. Kılıç cautioned that “people don’t price counterparty risk until something breaks,” suggesting that wrapped BTC solutions carry hidden fragility.
Dragosch offered a contrasting view of Bitcoin’s next growth phase. “Bitcoin as reserve collateral is the durable trade, the next leg of adoption runs through institutions and balance sheets, not necessarily through onchain execution layers,” he said.
Onchain activity is consolidating around venues like Hyperliquid and major centralized exchanges that control direct user relationships. Lending rates for BTC at centralized exchanges range from 2% to 4%, a floor that Bitcoin-native DeFi protocols have struggled to undercut sustainably.
Botanix co-founder Willem Schroé had previously claimed the platform offered “the best rates in the industry,” but competitive pressure from both Ethereum-based wrapped BTC products and centralized venues proved insurmountable.
