SUBFROST FUEL airdrop step by step tutorial
The SUBFROST Permafrost Preseason is a points campaign that is open as of 28 October 2026. Joining involves depositing BTC/USD liquidity into the Permafrost vault and placing the resulting cBTCUSD in a farm, which earns points on every block until block 986,100. SUBFROST plans to exchange points for FUEL once the token exists, at a rate not yet published.
Live · checked 28 October 2026
As of 28 October 2026, the SUBFROST announcement "Permafrost Preseason Starts Today" says farms in the Permafrost vault earn points on every block, and that the preseason spans blocks 973,200 to 986,100.
Earn points toward FUEL by depositing BTC/USD LP in the SUBFROST Permafrost vault and farming the cBTCUSD it mints, live until block 986,100.
What is SUBFROST?
SUBFROST is a Bitcoin-native DeFi project that offers swaps, AMM liquidity and vaults on Bitcoin Layer-1. Its documentation describes it as a decentralized custodian for Bitcoin, meant to let BTC take part in DeFi while staying on Bitcoin and out of any single company's hands.
People who put in BTC receive frBTC, a token redeemable one-for-one for the BTC locked behind it. That BTC is held by a group of independent signers using threshold signing: the signing key is divided among the group, so none of them can move funds alone. The docs say there are currently 9 signers, with room to scale to 255.
SUBFROST runs as a layer that watches Bitcoin and coordinates its signers, rather than as a chain of its own, so activity stays on Bitcoin L1. Supported assets include BTC, frBTC, frUSD, USDT, USDC, DIESEL and FIRE.
How SUBFROST works
SUBFROST locks native BTC with its group of signers and issues frBTC against it, and frBTC then moves through AMM pools and vaults on Bitcoin. The Permafrost vault takes BTC/USD LP and issues cBTCUSD, a token that stands for your slice of the vault's holdings. Leaving the Permafrost vault carries a 5% charge, and you can leave in any block. Of that charge, 4 percentage points go to the holders who remain and 1 goes to the protocol.
In the Permafrost Preseason, a farm holding cBTCUSD earns points on every block. A farm's points grow with the amount of cBTCUSD in it, the number of preseason blocks it stays open, and its multiplier, all multiplied together. The preseason covers blocks 973,200 through 986,100, roughly three months. At its end, each farm receives a fraction of FUEL equal to its points over the combined points of all farms still open. Redeeming a farm early removes its points.
Bonding FIRE raises the multiplier from 1x with no FIRE up to 1.5x at the full bond, which is 5% of the farm's value. The bond is permanent: the FIRE goes to the protocol's FIRE sink and is not returned when the farm is redeemed.
The conversion rate between points and FUEL has not been shared, and the FUEL token generation event is unannounced.
The FUEL airdrop
The campaign pays points, not yet a token: SUBFROST intends to settle the points that cBTCUSD farms earn during the preseason in FUEL, at a rate it has not shared. A wallet qualifies by depositing BTC/USD LP into the Permafrost vault, farming the cBTCUSD received, and keeping the farm open until block 986,100.
Step by step: how to get the FUEL airdrop
Stay safe: a real airdrop never asks for your seed phrase or private key. Use only the official links on this page, and treat any message that offers help with a claim as a scam.
Step 1: Get BTC/USD LP
On the Permafrost vault page, convert BTC into BTC/USD LP in a single zap, or supply frBTC and frUSD together.
Step 2: Deposit the LP into the Permafrost vault
The vault issues cBTCUSD in return, a token that represents your portion of what the vault holds. Held without a farm, cBTCUSD collects the vault's drip but scores no points. Leaving the vault later costs 5% of the position.
Step 3: Open a farm from the Farm tab
Create a farm from the Farm tab and set how much cBTCUSD it holds; scoring begins with the following block. The Rewards page lists your farms, their multipliers and your projected share.
Step 4: Decide whether to bond FIRE
Bonding is optional and raises the multiplier up to 1.5x, but it is permanent, so read the announcement first. A full bond costs FIRE worth 5% of the farm. Bond only through the Farm tab.
Step 5: Keep the farm open until block 986,100
A farm that is closed before the preseason ends forfeits its points, so leave it in place. Check your farms and projected share on the Rewards page.
SUBFROST airdrop FAQ
Is the SUBFROST airdrop still live?
- Yes, the Permafrost Preseason is live as of 28 October 2026. SUBFROST's announcement gives the preseason span as blocks 973,200 to 986,100, roughly three months, and says farms earn points on every block. The conversion rate to FUEL and the date of the FUEL launch have not been announced.
Is there a SUBFROST token?
- FUEL is the token the preseason points are meant to convert to, but it has not launched. The project calls its token generation event unannounced and says holding points does not guarantee any amount of FUEL. The conversion rate is to be shared at a later time.
How much does joining the Permafrost Preseason cost?
- You deposit BTC/USD LP into the Permafrost vault and receive cBTCUSD as your share. You can withdraw whenever you like, but a withdrawal is charged 5% of the position, split between the remaining holders and the protocol. Bonding FIRE for the 1.5x multiplier is optional and permanent, up to 5% of the farm's value.
Which chain does the SUBFROST campaign run on?
- It runs on Bitcoin Layer-1. SUBFROST says the vault position settles on Bitcoin L1 in transactions you sign yourself, and its docs say it is not a separate blockchain or a sidechain. The LP you deposit is a pair of frBTC and frUSD.
How are Permafrost Preseason rewards earned and claimed?
- Points accrue on their own for every block a farm is open, so nothing needs to be claimed during the preseason. Points convert to FUEL at the token generation event or shortly after, a date SUBFROST has not announced, and the announcement expects the FUEL to vest. Redeeming a farm early removes its points.
