Shell Finance: How Bitcoin-native Stablecoins work on Fractal
What is Shell Finance?
Shell Finance is a platform that lets you use your Bitcoin and Bitcoin-native assets ($BTC, $Ordi, $Sats, $Dog, $FB, and Ordinals NFT) to borrow US dollars, without ever leaving the Bitcoin network.
Think of it like getting a loan using your house as collateral, except here you're using your Bitcoin assets as collateral and getting digital dollars, $sUSD in return.
Understanding $sUSD
$sUSD is an over-collateralized synthetic USD stablecoin by Shell Finance that maintains a 1:1 peg with the US Dollar.
Unlike many other stablecoins:
It's created natively on Bitcoin through the Runes Protocol
It doesn't rely on centralized reserves or collateral
It uses algorithmic mechanisms to maintain its peg
Key Benefits of Shell Finance
Truly Bitcoin-Native
Decentralized Mechanism: The entire system runs on Bitcoin's native programming (script contracts)
Keep Your Assets in Bitcoin: Use Bitcoin and Bitcoin assets (like Ordinals) as collateral without bridging to other blockchains. All your assets are non-custodial and secured by Bitcoin scrip
Works Like a Secured Loan
Put up Bitcoin or other Bitcoin assets as collateral
For every $1 of sUSD you borrow, you need at least $1.25-$1.50 in collateral
Your collateral remains securely locked until you repay your loan
No Central Control
Unlike traditional stablecoins that require a company to hold actual dollars in a bank, sUSD maintains its $1 value through market incentives and overcollateralization - all while staying completely on the Bitcoin network.

The integration of $sUSD on Fractal represents an important milestone in developing Bitcoin's DeFi ecosystem. By bringing a stable USD representation to Fractal, Shell Finance is helping to create a more complete financial system that preserves the decentralized, trustless properties that make Bitcoin valuable.
As the brc-20 swap module continues development toward its expected Q2 2025 launch on Bitcoin mainnet, $sUSD is positioned to play a role in the growing intersection of Bitcoin, Runes, and brc-20 tokens.
