Overview

RapidLaunch is one of the most popular Solana token launch platforms. With fees.fun, every deploy, sell, and bundle or sniper transaction you make on RapidLaunch costs 0.25% instead of ~1% — saving you 75% on every trade. Plus, your transactions execute faster through our multi-region, multi-shard backend.
fees.fun works directly inside the RapidLaunch interface. You don’t need to learn anything new — just use RapidLaunch like you always do. Lower fees, faster execution.

​
What you need

  • fees.fun extension installed and logged in
  • At least one Solana wallet imported into fees.fun
  • Wallet assigned as RapidLaunch deployer
  • SOL in your deployer wallet for transactions

​
Setup guide

Import your wallet

If you haven’t already, import the Solana wallet you use on RapidLaunch into fees.fun.
  1. Open the fees.fun popup
  2. Click Import Wallet
  3. Paste your private key and give it a name
  4. Click Import
This should be the same wallet you normally deploy with on RapidLaunch. If you use a different wallet for sniping, import that one too.

Assign as RapidLaunch deployer

  1. In the extension popup, go to your wallet details
  2. Assign it as the deployer for RapidLaunch
Your first Solana wallet is automatically assigned as the deployer for all platforms. You only need to change this if you want a different wallet for RapidLaunch.

Go to RapidLaunch

Head over to rapidlaunch.io and use it normally. fees.fun activates automatically — you’ll see a connection indicator in the extension popup showing you’re connected.

Deploy a token

Create a token on RapidLaunch exactly as you normally would:
  1. Fill in your token details (name, symbol, image, socials)
  2. Set your dev buy amount
  3. Choose your launch platform (Pump, Bonk, Moon, etc.)
  4. Click Deploy
fees.fun handles everything behind the scenes and your transaction goes through at 0.25% fee instead of RapidLaunch’s native fee.

​
Setting up sniper wallets

RapidLaunch supports launching with multiple “sniper” or “bundle” wallets that buy the token immediately after creation. fees.fun fully supports this — but you need to import every sniper wallet into fees.fun first.
1

Import your sniper wallets

Import each wallet you want to snipe with into fees.fun:
  1. Open the extension popup
  2. Click Import Wallet for each sniper wallet
  3. Give them descriptive names (e.g., “Sniper 1”, “Sniper 2”)
2

Configure in RapidLaunch

In RapidLaunch’s deploy interface:
  1. Import your sniper wallets if you haven’t
  2. Select Bundle or Snipe mode
  3. Select your sniper wallet addresses
  4. Set the buy amount for each wallet
The sniper wallet addresses in RapidLaunch must exactly match the wallets you imported into fees.fun. If they don’t match, the sniper buys won’t go through.

Deploy with snipers

Click Deploy and fees.fun takes care of the rest. Your token creation and all sniper buys are submitted together so everything lands in the same block.
All sniper buys land in the same block as your token creation — giving you the best possible entry.

​
Selling tokens

Selling works the same way — just use RapidLaunch’s sell button:
  1. Go to your token’s page on RapidLaunch
  2. Enter the amount you want to sell
  3. Click Sell
The sell goes through at the reduced 0.25% fee rate automatically.
fees.fun keeps track of your token balances across all wallets (deployer + snipers) so sells work correctly even when you have multiple wallets.

What fees.fun does on RapidLaunch

​
Troubleshooting

Make sure the wallet address in RapidLaunch matches a wallet you’ve imported into fees.fun. Open the extension popup and double-check the address.
Every sniper address in RapidLaunch must be imported into fees.fun with its private key. If fees.fun can’t find a matching wallet, that sniper buy won’t go through.
This can happen during high network congestion. Try:
  • Switching to a closer server region
  • Increasing the bribe/tip amount
  • Waiting a few seconds and trying again
Token balances are cached briefly for speed. Wait a few seconds after a buy for balances to refresh, or reload the page.
