According to the official documentation (archived at shellfinance.gitbook.io/shell), Shell Finance described itself as the "Decentralized Central Bank of Bitcoin" — a trustless lending protocol built natively on Bitcoin Layer 1. Below are the features the protocol shipped before ceasing operations.
Shell Finance was built directly on the Bitcoin Layer 1 network — not on a sidechain, not on a bridge. Users could borrow $sUSD without leaving Bitcoin's security model. This was a fundamental architectural distinction from projects on RSK or Stacks that required wrapping BTC.
Shell Finance issued $sUSD (sUSD•sUSD•sUSD), a synthetic stablecoin pegged 1:1 to the US dollar and built on the Runes Protocol. Users pledged Bitcoin L1 assets as collateral and received $sUSD in return — directly on Bitcoin L1, without involving Ethereum or wrapped assets.
Shell Finance's business model was explicitly modelled on MakerDAO: users deposited collateral to borrow a synthetic stablecoin, with the protocol serving as the intermediary. Unlike MakerDAO which relied on Ethereum smart contracts, Shell Finance implemented this through trustless Bitcoin Script contracts and a Peer-to-Pool framework for the UTXO model.
The protocol accepted an unusually wide range of Bitcoin L1 assets as collateral: native BTC, Ordinals NFTs (including NodeMonkes, Ordinal Maxi Biz, Quantum Cats), Runes tokens, BRC-20 tokens, and Atomicals (ARC-20). This multi-asset collateral model aimed to unlock liquidity from the entire Bitcoin on-chain asset ecosystem.
Shell Finance shipped a liquidation auction mechanism at mainnet launch (December 2024), allowing external liquidators to participate in auctions when collateral fell below required ratios. This was designed to maintain $sUSD peg stability and created a native arbitrage opportunity for sophisticated users in the BTCFi ecosystem.
Shell Finance's Darkman collection was positioned as the first Runes project integrating profile picture (PFP) mining with real DeFi utility. Darkman NFT holders received whitelist access and protocol benefits. The collection was designed to merge art, community identity and protocol governance — a mechanic that was novel in the Bitcoin Runes ecosystem.
The protocol was compatible with the major Bitcoin L1 wallets at launch: OKX Wallet, UniSat Wallet, and Xverse Wallet. This broad wallet compatibility was critical for user onboarding in the Bitcoin L1 DeFi space, where wallet fragmentation was a known barrier to adoption.
Shell Finance's core product was the $sUSD stablecoin — the first synthetic dollar issued on Bitcoin's Runes Protocol. Below is the archived protocol structure as documented before the project ceased operations.

Casey Rodarmor launched the Ordinals protocol on Bitcoin L1, enabling inscription of data onto satoshis. This triggered the BRC-20 token standard and, by late 2023, the Runes proposal — laying the technical groundwork for Shell Finance's approach to Bitcoin-native DeFi.
Shell Finance published its vision as a "trustless lending protocol built on Bitcoin L1", claiming to be the first DeFi project based on the Runes Protocol and the first Runes project integrating PFP mining with utility. The @ShellFinance_ Twitter account began building a community around the BTCFi narrative, ahead of the Bitcoin Halving in April 2024.
The team announced securing the parent inscription for BRC-20's 5-byte ticker $shell via @unisat_wallet — a significant early move to establish the protocol's token identity on the Bitcoin blockchain before the Runes protocol activation at the Halving.
Shell Finance launched the Darkman Genesis NFT whitelist campaign, offering 100 whitelist spots to Prometheans holders. Darkman was positioned as the first Runes project combining PFP art with DeFi utility — an innovative mechanic designed to build a loyal early adopter community ahead of the mainnet launch.
On December 4, 2024, Shell Finance launched its mainnet at app.shellfinance.xyz/borrow. The protocol supported borrowing $sUSD against BTC, NodeMonkes Ordinals, Ordinal Maxi Biz, Quantum Cats, Ordi, and Sats at launch. Runes collateral was announced for January 2025. OKX Wallet, UniSat Wallet, and Xverse Wallet were integrated at launch. Liquidation auctions went live simultaneously.
BTCFi searches and ecosystem activity peaked in early 2025, driven by Babylon Protocol's $4B+ in staked BTC and new Bitcoin L2 launches. Shell Finance, however, went inactive without further protocol updates or team communications. The $sUSD stablecoin and liquidity pools ceased to be actively maintained.
Shell Finance ceased all operations. The protocol went offline, the team went silent on social media, and $sUSD was no longer supported. The gitbook documentation (shellfinance.gitbook.io/shell) remained accessible as an archive. The BTCFi space continued to grow without Shell Finance — with Liquidium, Sovryn and Stacks-based protocols absorbing its intended niche.
Despite Shell Finance's shutdown, the BTCFi and Bitcoin DeFi categories continue to attract search and capital. Babylon Protocol holds $4B+ in staked BTC, Rootstock hosts $100M+ in TVL, and new Bitcoin L2 projects (Citrea, Bitlayer) launched in early 2026. Shell Finance's architectural vision — native Bitcoin L1 lending without wrapping — remains an active area of development through Liquidium's PSBT-based model.
Shell Finance described itself as the "Decentralized Central Bank of Bitcoin". The core argument was that Bitcoin's $1 trillion+ in idle capital was fundamentally underutilized because no trustless lending protocol existed natively on Bitcoin Layer 1. Shell Finance aimed to unlock this capital by allowing BTC holders to borrow $sUSD directly — without bridges, without wrapped assets, and without leaving Bitcoin's security model.
The vision was explicitly modelled on MakerDAO — but for Bitcoin. The team positioned Shell Finance as the first meaningful attempt to bring the MakerDAO model to Bitcoin L1 using the Runes Protocol. Execution stalled at mainnet stage.

Liquidium operated as a pure peer-to-peer Bitcoin lending protocol where borrowers created loan offers with their Ordinals or Runes as collateral and lenders accepted by completing the PSBT. Settlement happened automatically via Bitcoin Script logic — entirely on-chain, entirely non-custodial. This was the architectural vision Shell Finance had described but never fully shipped. The platform targeted exactly the Bitcoin L1 DeFi niche that Shell Finance had aimed to unlock, with proven mainnet traction into 2026.
Sovryn built on RSK (Rootstock), a Bitcoin sidechain merge-mined with the same miners securing Bitcoin. Its Zero protocol was the most direct functional equivalent to Shell Finance's vision: users could lock BTC (as rBTC) and borrow ZUSD at 0% interest, paying only a one-time origination fee. The platform also offered margin trading, spot swaps, lending pools and governance — the broadest BTCFi feature set available in 2026. The trade-off vs Shell Finance was the federated bridge model to RSK, which introduced trust assumptions not present in a pure Bitcoin L1 approach.
Stacks brought smart contracts and DeFi to Bitcoin through its Proof of Transfer (PoX) consensus mechanism, where STX block producers locked BTC as collateral and earned Bitcoin yield. Arkadiko, built on Stacks, allowed users to mint USDA stablecoin by locking STX — with the locked STX earning Bitcoin yield via PoX. The $208M TVL and sBTC integration (native BTC on Stacks without wrapping) positioned the ecosystem as the leading Bitcoin L2 DeFi option for users who wanted Shell Finance's stablecoin functionality but on a proven, active platform.
Money On Chain built on Rootstock (RSK) — the merge-mined Bitcoin sidechain — to issue Dollar On Chain (DOC), the first stablecoin exclusively backed by Bitcoin. With $100M+ TVL, it was the largest protocol on Rootstock and a proven reference for BTC-collateralized stablecoin issuance. Unlike Shell Finance's Runes-based approach, Money On Chain relied on Rootstock's federated bridge, which introduced a trust assumption — but also provided years of battle-tested security that Shell Finance never reached before shutting down.
Bitflow operated on the Stacks blockchain with a specific focus on providing yield on Bitcoin assets without bridges. Its sBTC compatibility — enabling native Bitcoin to be used in Stacks DeFi — positioned it for growth as the sBTC ecosystem matured in 2026. Unlike Shell Finance's stablecoin borrowing model, Bitflow focused on liquidity provision and yield generation, making it better suited for BTC holders seeking passive returns rather than active borrowing.
Babylon allowed BTC holders to stake native Bitcoin to secure Proof-of-Stake networks — entirely non-custodially, with Bitcoin staying in user wallets. By 2026, Babylon had accumulated over $4 billion in staked BTC, making it the highest-TVL BTCFi protocol. While its use case differed from Shell Finance (staking vs lending/stablecoin), it dominated the narrative of "making idle BTC productive" that Shell Finance had aimed to address. Slow exits were a known constraint, making it more suitable for long-term BTC holders than active DeFi users.
