Introduction: Bringing DeFi to Bitcoin
Bitcoin is widely used to store and transfer value, but using BTC in decentralized finance has traditionally involved extra steps. Traders may need a centralized exchange, a bridge, or a token representation on another network before they can access DeFi applications.
SUBFROST is building Bitcoin-native DeFi infrastructure around the Alkanes metaprotocol. Its services bring token swaps, automated market maker (AMM) liquidity, vault strategies, and developer tools into the Bitcoin ecosystem. The goal is to let people interact with supported Bitcoin-native assets while transactions and application activity are settled on Bitcoin Layer 1.
Rather than treating Bitcoin only as an asset to hold, SUBFROST aims to make it usable in a broader range of on-chain financial applications.
1. Bitcoin-native token swapping
Token swapping is one of SUBFROST's core services. Users can exchange supported assets through AMM liquidity pools instead of waiting for a traditional exchange to match buyers and sellers. The app displays a quote before a trade, including the estimated amount to receive and the applicable price impact or slippage settings.
SUBFROST also uses routing across available pools. A multi-hop route can move through more than one market when that provides a suitable path between the selected assets. For supported routes, a user can start with native BTC without manually completing a separate wrapping step: the app handles the required frBTC conversion as part of the swap flow.
Before confirming a trade, users should review the quoted output, minimum amount received, network fee, pool liquidity, and slippage tolerance. Quotes can change as pool balances and market prices move.
2. AMM liquidity pools
An automated market maker is a trading pool that holds two or more assets and allows users to swap against the pool according to its pricing rules. Instead of relying on a conventional order book, the pool uses its available liquidity to calculate trade prices.
SUBFROST lets users add supported asset pairs to its AMM pools and receive a liquidity-provider position. Liquidity helps make swaps possible. Depending on the pool's rules and activity, liquidity providers may receive a share of trading fees or other incentives.
Providing liquidity is not risk-free. The value of deposited assets can change relative to one another, trading volume may be limited, and fees or incentives are not guaranteed. Users should read the details of each pool and understand its pricing model before depositing.
3. Bitcoin-native assets: frBTC and frUSD
SUBFROST's ecosystem includes assets designed to make Bitcoin and dollar-denominated value usable in Bitcoin-native applications.
frBTC is a programmable Bitcoin-native asset designed to represent BTC on a 1:1 basis. SUBFROST documentation describes a process in which BTC is locked on Bitcoin mainnet and corresponding frBTC is issued. Users can use frBTC in supported applications and redeem it for native BTC under the protocol's redemption process.
frUSD is a dollar-denominated asset used in the Bitcoin-native market. The BTC/USD pool pairs frUSD with frBTC, allowing users to trade between Bitcoin exposure and a dollar-denominated asset while settling on Bitcoin Layer 1. The official documentation describes the reserve and redemption arrangements, including the relevant process and conditions.
These assets have specific mechanisms, dependencies, and risks. Read the official documentation for reserve details, redemption requirements, fees, and supported routes rather than assuming that every asset behaves exactly like native BTC or a bank-held dollar.
4. DeFi vaults and strategies
SUBFROST provides vault strategies for users who want to put eligible liquidity positions to work. The FIRE Vault is associated with the DIESEL/frBTC liquidity pool and offers staking or bonding mechanisms connected to FIRE incentives. The PERMAFROST Vault is presented as a strategy for the frUSD/frBTC liquidity position.
Vault strategies can involve lockups, changing pool prices, liquidity risks, smart-contract risks, and reward rates that vary over time. A displayed or historical reward rate should never be treated as a guaranteed return. Users should review each vault's current terms, eligibility, withdrawal rules, and risks before participating.
5. Wallets and apps
SUBFROST can be accessed through its web app, with additional client options described in its wallet documentation. The documentation lists an Android app and a Chrome browser extension, while iOS availability is described as pending review. Availability can change, so users should check the official downloads and wallet pages before installing anything.
The wallet experience is designed for Bitcoin and Alkanes assets. Depending on the client, users can manage balances, send and receive assets, review transaction activity, connect to supported applications, and access swap or liquidity features.
Wallet security remains the user's responsibility. Keep the recovery phrase private, store it securely offline, and never share it with anyone claiming to provide support. Always verify the domain and download source before connecting a wallet or signing a transaction.
6. Developer tools and Bitcoin infrastructure
SUBFROST also provides infrastructure for developers building on Alkanes. Its developer documentation describes tools such as alkanes-cli, a TypeScript SDK, and hosted JSON-RPC access. These tools can help developers read chain data, interact with contracts, build applications, and integrate Bitcoin-native assets.
This developer layer matters because a DeFi ecosystem needs more than a swap interface. It also needs documentation, data access, contract tooling, and infrastructure that other teams can use to create additional applications.
How SUBFROST works together
These services are connected. Bitcoin and supported assets can enter the app's trading flow; AMM pools provide liquidity for swaps; frBTC and frUSD support Bitcoin-native markets; vault strategies offer ways to deploy eligible liquidity positions; and developer tools allow other builders to work with the underlying infrastructure.
The result is an ecosystem focused on making Bitcoin-native financial applications easier to access without presenting Bitcoin as a separate chain or implying that every feature is available on every client.
*Getting started with SUBFROST
*
To explore the platform, begin at the official SUBFROST website and open the web app from there. Read the getting-started guide before creating or connecting a wallet. Start with a small amount if you are learning how swaps and pool transactions work, and review every transaction before signing.
Do your own research before using any DeFi product. Smart contracts, liquidity pools, asset redemption mechanisms, market volatility, and wallet operations all involve risk. Never share your recovery phrase or sign a transaction you do not understand.
Conclusion
SUBFROST brings together Bitcoin-native swaps, AMM liquidity, assets such as frBTC and frUSD, vault strategies, wallet clients, and developer infrastructure. Its focus is to expand what users and developers can do with Bitcoin while keeping supported application activity on Bitcoin Layer 1.
For Bitcoin holders, traders, liquidity providers, and builders, SUBFROST offers a set of tools to explore the developing Bitcoin DeFi ecosystem. The best way to understand each service is to review its documentation, check which features are live, and evaluate the risks before using it.
