Overview
Butane lets you lock up ADA to create tokens that track the price of something else, like a US dollar or a commodity, without selling the ADA you already own. Think of it like using your car as security for a loan. You hand over the keys to a locked garage, you get cash to spend, and you get the car back when you settle the loan. With Butane the locked ADA keeps earning staking rewards while it sits in the garage, which most other systems on other blockchains cannot do.
Butane is fully open source and built on Cardano. Its rules are written into automated code that anyone can inspect, and the whole design is laid out in a public yellow paper. The team behind Butane also maintains Blaze Cardano, a building-block toolkit used by other Cardano projects including SundaeSwap, Fortuna, and Rocket.
Key Features
- Get spendable tokens without selling your ADA. You lock ADA, or other Cardano-native tokens, as the money that backs the position. In return Butane gives you new tokens that track the price of a target asset, like a stablecoin (a token designed to hold a steady value, usually one US dollar). When you pay back what you borrowed, you get your ADA out.
- Bundle several actions into one click. Butane lets you open, adjust, close, or wind down several positions in a single transaction. If any step fails, the whole bundle is cancelled, so you are never left half-finished during a fast market move.
- Keep earning staking rewards on locked ADA. ADA used as backing keeps its delegation to a stake pool, so you continue earning epoch rewards on the same balance. This works because Cardano separates the right to spend ADA from the right to earn rewards on it.
- Pay interest in BTN at a discount. Interest on a position can be paid in the borrowed token or partly in BTN, Butane's voting token, at a lower rate. The split is capped so BTN can never be used to create tokens that are not fully backed.
What to Expect
Most visitors arrive at the Butane app to open or manage a position. The interface shows a list of available tracker tokens and a simple flow where you pick what to lock, choose how many tracker tokens to mint, and review the position's health before signing. Closing or adjusting a position works the same way in reverse. A separate markets view shows live data on how each tracker token is performing.
For people researching the project before connecting a wallet, the docs site walks through how positions, fees, forced sales, and safety mechanisms work in practice. A forced sale, sometimes called a liquidation, is what happens when the value of your locked ADA drops too low. The protocol automatically sells the position to keep every tracker token fully backed. The whitepaper covers the economics, and the yellow paper covers the technical details, both useful before depositing funds.
Builders interested in Cardano building tools rather than tracker tokens can look at Blaze, the team's TypeScript toolkit published separately at blaze.butane.dev. It is used by several major Cardano apps and is unrelated to Butane's tracker token product, though both come from the same team.
