Bubble docs

Bubble is a Solana launchpad where every coin's ticker is made of letters, and every letter is a key. Hold a bubble, and you earn a share of the trading fees of every coin whose ticker contains that letter.

• 26 bubbles, A to Z.
• Launch a coin and its ticker decides which bubbles it pays.
• Hold bubbles and you earn from every coin that uses your letters, launched by anyone.
• Coin creators race to collect all 26 letters and win the A–Z Race pot.

• One bubble per letter per wallet. You can hold A, B and C, but not two A bubbles.
• Price. The first bubble of a letter costs 0.1 SOL. Each new bubble of the same letter costs 1.25× the last one (0.1 → 0.125 → 0.156 → 0.195 …).
• Buying. On the Bubble page, every card has Buy and Bubble stats. Buy goes straight to your wallet to approve, at the price shown on the card (the next key's price). Bubble stats opens the key's page with its holders, sales and earnings.
• Reselling. You can list your bubble for other people to buy. The listing price can't be higher than the next new bubble of that letter.
• Live bubble trades. The panel beside the cards shows every bubble bought across all letters (new bubbles and resales), with price, buyer and a link to the transaction.
• Order. The Bubble page shows A → Z by default. Use Cheapest, Fewest holders or Most launches to re-sort, and the search box next to them to jump to a letter.

Coins launch on pump.fun, paired with $BUBBLE. Every trade pays a 1.5% creator fee to Bubble, split 60/30/10 (50/30/20 after graduation) between bubble holders, the A–Z Race pot and the creator, paid in $BUBBLE.

The fee is split like this:

How the bubble holders' share is split. It's divided between the letters of the ticker by how many times each letter appears. In KEK, K appears twice, so K gets 2/3 and E gets 1/3. Each letter's part is then shared equally between that letter's eligible bubble holders.

• Hold the bubble at least 1 minute before the coin launches. Bubbles bought later don't earn from that coin. They earn from coins launched after.
• Creators don't earn from their own coin through bubbles.
• Rewards unlock 10 minutes after you got the bubble. If you sell or transfer the bubble before then, those locked rewards go to the other holders of that letter.
• Buying a key doesn't buy its past earnings. You only earn from coins that launch while you hold it.
• Claim your unlocked rewards in Portfolio.
• If nobody eligible holds a letter of a coin, that letter's part goes to the launchpad.

The race is a prize pot that grows with every trade on Bubble.

• The pot. 30% of all trading fees go into it, from every coin, before and after graduation. The live pot is shown in the top bar and on the A–Z Race page.
• Collecting letters. When a creator's coin graduates, they get one letter from its ticker, picked at random in a way anyone can check (it uses the Solana blockhash after the graduation). The ticker needs at least 3 different letters to count.
• Keeping a letter. A new letter is pending for 72 hours. It's kept if the coin is still worth $30,000 or more at the end and wasn't flagged (bundled, creator sold, or creator buy over the limit). Otherwise it's removed.
• Winning. The first creator to collect all 26 letters wins the whole pot.
• Payout. The prize is sent to the winner's wallet automatically 24 hours after the win, once the letters are checked again.
• Gold tick. Winners get a permanent gold tick next to their wallet across the site (×2, ×3 for repeat wins).
• New race. The moment someone wins, a new race starts and the pot begins again from 0. Letters from the previous race don't carry over.

• Ticker: letters A–Z only (up to 10). It decides which bubbles your coin pays.
• Picture and links: add an image and an optional X post. Your coin's website is set to its Bubble page, so every trading terminal links back here.
• First buy (optional): buy your own coin in the same transaction that creates it, so you're first in line. Creators can buy at launch; how much they bought is shown on every coin page.
• One click: press Create coin and approve once in your wallet. You're taken to your coin's page when it's live.
• Graduation: when the pump.fun bonding curve fills, the coin graduates and the creator gets a random letter from its ticker.
• Creator earnings are paid to your wallet automatically, every 30 minutes.

• Coin pages live at launchonkeys.com/coin/<contract address>. The browser tab shows the ticker and live market cap.
• Buy and Sell with one tap on a preset amount, or type your own. Your wallet asks you to approve each trade. Turn on 1-tap to send a trade as soon as you tap an amount.
• Slippage can be 5%, 10% or 20%. Every trade shows a link to the transaction.
• Quick buy buttons on Launches, Pulse and Discover buy straight from the list.
• Clear errors: if something goes wrong you'll see a short message, like "Not enough SOL. You have 0.25 SOL, try 0.247 SOL or less." or "Price moved too fast. Try again."

• Search (⌘K, Ctrl+K or /) works from any page. Type a ticker, a coin name, or paste a contract address (the full address, or just the first few characters). A single letter jumps to that bubble. A wallet address shows that wallet's coins and keys.
• Launches shows new and live coins. Discover sorts every coin by trending, market cap, volume, gainers, holders, fees or newest, and filters by the bubbles a coin pays.

Your bubbles, your rewards (locked, claimable and claimed), the coins you hold and the coins you created, all in one place. Claim unlocked bubble rewards here.
