How to launch a Solana token
A Solana launch takes 5 steps: connect a wallet, add a name, symbol and image, choose an optional dev-buy, check the simulated cost and sign once. On KABOOM! a dev-buy pays a 1% creation fee. On Solana, everything is open on mainnet with real SOL at stake: launching, trading and the trading tools, every transaction signed by your own wallet.
Status. On Solana, everything is open on mainnet with real SOL at stake: launching, trading and the trading tools, every transaction signed by your own wallet. A network without a launch config says so on the launch page.
What you need before you start
- A Solana browser wallet, or a wallet from the built-in wallet vault. The wallet that signs becomes the maker.
- SOL for the network fee and the rent of the new accounts, plus whatever you want to spend on an optional dev-buy.
- A name, a ticker symbol and a square image (PNG, JPEG, GIF or WebP, up to 2 MB).
- Optional: a short description, a website, an X link and a Telegram link.
The 5 steps
Connect a wallet
Open the launch page and connect a Solana browser wallet, or unlock the built-in wallet vault. The wallet that signs becomes the maker of the coin and needs SOL for the network fee, the account rent and any dev-buy.
Add the name, symbol and image
Enter the coin name and its ticker symbol and upload an image of up to 2 MB. A description, a website, an X link and a Telegram link are optional. The image and metadata are stored under their content hash, so the file behind the on-chain link never changes.
Choose an optional dev-buy
Decide how much SOL, if any, you spend on your own coin inside the launch transaction. The pool is created in that same transaction, so nobody can buy before you. The coin page shows your dev-buy as a share of the supply from the first block.
Check the simulated cost
Before you sign, the launch page simulates exactly the transaction you are about to sign and shows the dev-buy, the tokens you receive, your share of the supply, the network fee, the accounts and rent, the total that leaves your wallet and your balance afterwards.
Sign the launch transaction
Sign once. The transaction creates the token and its bonding curve pool and makes your dev-buy. The coin then has its own page with the price, the chart, the trades, the disclosure sheet, the vesting schedule and the fees, all read from the chain.
The launch rules
Every Solana coin on KABOOM! launches with the same on-chain config, so buyers can check the rules once. You do not pick these values. The curve numbers below are the mainnet config; the test curve, used only in our own test runs, runs from 1 to 10 SOL.
| Rule | Value | What it means for buyers |
|---|---|---|
| Supply | 1,000,000,000 tokens, 6 decimals | Set at launch. The coin page reads the mint authority from the chain. |
| Token authority | The SDK's immutable option | Chosen so that nobody keeps a mint or metadata update authority; check the coin page. |
| Curve (the mainnet config) | 30 to 400 SOL market cap | The price follows a fixed curve until migration. |
| Maker vesting | 5% of supply, 30 steps over 30 days | Goes into a vesting escrow at migration and unlocks gradually; no cancel path was found. The maker's own dev-buy tokens are not locked. |
| Liquidity | 100% permanently locked at migration | The locked liquidity cannot be withdrawn; fee claims on it are untested. |
| Trading fee | About 2% per trade on the curve | On the nominal 2%: 0.4% Meteora, 1.104% platform, 0.496% maker. It accrues in the pool. |
The method page derives each value from the config in the code.
What a launch costs
KABOOM! charges no launch fee. What leaves your wallet is the Solana network fee, the rent for the accounts the launch creates, your optional dev-buy and, with a dev-buy, a 1% creation fee on it to the platform in the same transaction. The 1% creation fee goes entirely to the platform; referral rewards come from trading and tool fees, never from the creation fee. The launch page shows the creation fee before you review, and the exact total from a simulation of the transaction you are about to sign, together with your balance afterwards.
| Cost item | Who receives it | How much |
|---|---|---|
| Launch fee | — | None |
| Creation fee (with a dev-buy) | KABOOM!, in the launch transaction | 1% of the dev-buy; none without one. 100% platform, not shared with referrers |
| Network fee | Solana validators | Set by the network; shown in the simulation |
| Account rent | Stored in the new accounts | Shown in the simulation |
| Dev-buy (optional) | The bonding curve pool, in exchange for tokens | Your choice, including zero |
A measured example: in a test run on the smaller test curve, a launch with a 0.1 SOL dev-buy took 126,546,960 lamports in total. That is 0.1 SOL for the dev-buy and about 0.0265 SOL for the network fee and rent, and the simulation matched the real balance change to the lamport. That run predates the creation fee; today the same launch also pays 0.001 SOL (1% of 0.1 SOL) to the platform. Your numbers depend on the network and the dev-buy.
After launch: the coin page
The coin gets its own page. Everything on it is read from the chain when the page loads:
- Price, market cap and progress along the curve towards migration.
- A chart and the trade list, built from the swap events in the pool's own transactions.
- The disclosure sheet: the dev-buy share, and the early-buyer concentration behind the badge. The bundle layer of the disclosure badge is live; cluster figures are not live yet, so no cluster number is shown.
- The vesting schedule of the maker allocation and the LP lock status.
- The fee split, and a button for the maker to claim their fee share.
How the badge is measured is on the method page. For what buyers should check, read how to spot a rug pull.
When the curve completes
At a market cap of 400 SOL in the mainnet config (10 SOL on the test curve) the curve is complete. The coin migrates to a Meteora DAMM v2 pool with a 1% fee tier and no migration fee, 100% of the liquidity is permanently locked, and the maker allocation starts to vest. After migration the coin trades in that pool, outside this app's trade panel. The bonding curve guide explains how the price gets there.
Frequently asked questions
How much does it cost to launch a Solana token?
On KABOOM! there is no launch fee. You pay the Solana network fee, the rent for the new accounts and your optional dev-buy. In a test run on a smaller test curve, a launch with a 0.1 SOL dev-buy took 126,546,960 lamports (about 0.127 SOL) in total, and the simulation matched the real balance change exactly. That run predates the creation fee: every Solana launch with a dev-buy pays a 1% creation fee on the buy (the dev-buy, plus every bundle wallet on a bundle launch) to the platform, inside the launch transaction; a launch without a dev-buy pays none. The 1% creation fee goes entirely to the platform; referral rewards come from trading and tool fees, never from the creation fee. On a 0.1 SOL dev-buy that is 0.001 SOL.
Do I need to code to launch a token?
No. The launch page is a form: name, symbol, image, optional links and an optional dev-buy. The page builds the transaction, simulates it and shows the result. You only review it and sign in your wallet.
Can I change the token name or image after launch?
Plan as if you cannot. Coins are configured with the bonding-curve SDK's immutable token-authority option, chosen so that nobody, the maker included, can update the metadata later. The coin page reads the metadata from the chain. Check every field before you sign.
What is a dev-buy, and is it public?
A dev-buy is SOL the maker spends on their own coin inside the launch transaction. It is optional. It is also public: the Solana coin page shows the dev-buy as a share of the supply, so buyers can see how much the maker took at launch. Dev-buy tokens are not vested and can be sold at any time.
What happens when the bonding curve fills up?
The coin migrates to a Meteora DAMM v2 pool: at 400 SOL market cap in the mainnet config, at 10 SOL on the test curve. 100% of that liquidity is permanently locked, and the maker's 5% allocation starts unlocking in 30 steps over 30 days. After migration the coin trades in that pool, outside this app's trade panel.
How does the maker receive trading fees?
Every trade on the curve pays about 2%. After Meteora's 20% share, the maker receives 31% of the rest: 0.496% on the nominal 2%. It accrues on-chain in the pool, and the maker claims it from the coin page.
Can I launch on Solana mainnet with KABOOM! today?
Yes. On Solana, everything is open on mainnet with real SOL at stake: launching, trading and the trading tools, every transaction signed by your own wallet. A network without a launch config says so on the launch page.
