About UTXO Stack
UTXO Stack is rollup-as-a-service for the Bitcoin ecosystem, letting teams issue a Bitcoin Layer 2 that keeps the UTXO model without building one from scratch. It targets the fact that most Bitcoin L2s actually pair an EVM with a bridge, binding weakly to mainchain security and adding trust assumptions the moment assets cross.
The mechanism is natively compatible with RGB++, so assets move between the main chain and isomorphic chains through isomorphic binding rather than a bridge; new chains gain both Bitcoin hashpower and restaking security, and developers generate a chain, explorer and wallet suite from configuration. Wallets and the development kit became available on mainnet during 2026. The route requires users to understand UTXO and isomorphic binding semantics, a steeper learning curve than EVM ecosystems.
UTXO Stack, a modular BTC Layer2 platform, has achieved two pivotal milestones. First, it released its whitepaper, 2025 roadmap, and new website, formally establishing its technical framework for one-click chain issuance and modular architecture. This marks the transition from concept to a structured development plan. Second, the platform announced its strategic transformation into a Lightning Network staking layer, introducing a token incentive mechanism. This shift is significant as it moves beyond infrastructure to actively enhance liquidity and user participation, positioning UTXO Stack as a key enabler for scalable Bitcoin payments. These events represent long-term strategic pivots, not routine updates, setting the stage for broader ecosystem adoption.
UTXO Stack announced in September 2026 that it is transforming into the liquidity staking layer for the (Hybrid) Lightning Network, introducing a token incentive mechanism to encourage users to stake CKB and BTC and boost state-channel liquidity. Its infrastructure includes the Hybrid LN, a Decentralized Liquidity Staking Pool (DLSP), swapping nodes, a wallet and a P2P payment SDK; the DLSP runs on CKB smart contracts, is non-custodial, and uses token-gated governance to select nodes.
Developed by CELL Studio in the Nervos / CKB ecosystem, UTXO Stack enables one-click launch of UTXO-architecture BTC Layer2s with native RGB++ integration. RGB++ isomorphically maps BTC UTXOs to CKB Cells so assets inherit Bitcoin security while gaining Turing-complete programmability.
Future strategy and roadmap: UTXO Stack will fuse Hybrid LN with Fiber Network, bringing the RGB++ native stablecoin RUSD into Lightning with zero-cost channel opens and using DLSP staking pools to fund LN and FN liquidity. A P2P payments SDK and one-click UTXO BTC L2 let it build a bitcoin payments and BTCFi ecosystem and attract nodes and merchants.
UTXO Stack was founded and is led by Cipher Wang. He studied automation at Zhejiang University and took a master's in theoretical physics at Peking University, encountered Bitcoin in 2013, joined a blockchain research institute in 2016 to work on consortium chains and digital currency policy projects, and in 2018 became a co-founder of Nervos, where he shaped the Cell model and the CKB virtual machine. He left the foundation in 2021 to build the passkey wallet JoyID, proposed the Bitcoin layer-one asset protocol RGB++ in February 2024, and that same year started UTXO Stack. The team grew out of CELL Studio, incubated by the CKB Eco Fund. Wang owns both technology direction and external affairs, the engineering group is split across protocol, client and tooling, and most core members are long-time Nervos and CKB ecosystem contributors.
