Overview

J7 Tracker combines token tracking with launch capabilities. With fees.fun, your deploys and sells on J7 cost 0.25% instead of ~1% — saving you 83% on every trade. Your transactions also execute faster through our multi-region, multi-shard backend.
fees.fun plugs into J7 Tracker’s trading system. Use J7 normally and your transactions go through our infrastructure automatically — lower fees and faster execution.

​
What you need

  • fees.fun extension installed and logged in
  • At least one Solana wallet imported into fees.fun
  • Wallet assigned as J7 Tracker deployer
  • SOL in your deployer wallet (and bundle wallets, if using them)

​
Setup guide

Import your wallet

Import the Solana wallet you use on J7 Tracker:
  1. Open the fees.fun popup
  2. Click Import Wallet
  3. Paste your private key and name it
  4. Click Import
The wallet address must match the one configured in J7 Tracker. Double-check both addresses match before deploying.

Assign as J7 deployer

  1. In the extension popup, go to your wallet details
  2. Assign it as the deployer for J7 Tracker

Go to J7 Tracker

Head over to j7tracker.io or j7tracker.com. fees.fun activates automatically.

Start deploying

Use J7’s deploy interface as usual. When you launch a token, fees.fun takes care of routing it through our lower-fee infrastructure.

​
Setting up bundle wallets

J7 Tracker has its own bundle wallet system. fees.fun reads directly from J7’s wallet configuration, so setup is straightforward — just make sure your wallets are imported.
1

Import all bundle wallets into fees.fun

For each wallet you want to use in J7’s bundle:
  1. Import the wallet into fees.fun with its private key
  2. Name them clearly (e.g., “J7 Bundle 1”, “J7 Bundle 2”)
These must be the exact same wallet addresses you configure in J7’s bundle tab.
2

Configure bundles in J7 Tracker

In J7 Tracker’s interface:
  1. Go to the Bundle tab
  2. Add your wallet addresses
  3. Select which wallets to include in your bundle
  4. Set buy amounts for each wallet
3

Deploy with bundle

When you deploy a token with bundles selected, fees.fun picks up your bundle wallet selection from J7 and submits the deploy + all bundle buys together. Everything lands in the same block.
fees.fun reads your bundle wallet selections directly from J7’s interface, so whatever you configure in J7 is automatically picked up.

​
Selling tokens

To sell tokens from J7 Tracker:
  1. Use J7’s sell interface as normal
  2. Select the wallet to sell from
  3. Enter the amount or percentage
  4. Click sell
The sell goes through at the reduced 0.25% fee rate.
When selling from a bundle wallet (not your main deployer), fees.fun automatically detects which wallet you’re selling from and uses the correct key.

​
Troubleshooting

This means fees.fun couldn’t match J7’s wallet address to one you’ve imported. Check that:
  1. The wallet is imported in fees.fun (check the popup)
  2. The address in J7 matches exactly
  3. You haven’t recently removed the wallet from fees.fun
Make sure:
  1. You’ve selected your bundle wallets in J7’s Bundle tab
  2. You’ve refreshed the J7 page after importing wallets into fees.fun
  3. The wallet addresses in J7 match what you imported into fees.fun
When selling from a non-deployer wallet, fees.fun needs that wallet’s private key. Make sure it’s imported in fees.fun. If the sell still fails, the wallet might not have enough tokens.
If you’re having trouble connecting:
  1. Refresh the J7 page
  2. Check the fees.fun popup for connection status
  3. Try switching to a different server region
