General

fees.fun is a Chrome extension that reduces trading fees on Solana token launch platforms. It works on RapidLaunch, Uxento, J7 Tracker, and Axiom — saving you up to 83% on every trade.
fees.fun charges 0.25% per transaction instead of the 1-2% (with 0.01 SOL minimums) that platforms normally charge. There’s no subscription, no upfront cost — you only pay the reduced fee when you trade.

​
Wallets

For RapidLaunch, Uxento, and J7 — yes. Import the same wallets you already use on those platforms into fees.fun so it can sign transactions at lower fees.For Axiom — no. fees.fun works on Axiom automatically without any wallet setup.
Yes. fees.fun can create a fresh Solana wallet for you instantly. If you do this, you’ll also need to import that wallet’s private key into whatever platform you want to use it on.
Yes. fees.fun stores no private keys in our database — we can’t, because we don’t have them. Wallets created in fees.fun are managed by Turnkey, a non-custodial key provider with hardware-level security. Imported wallets are encrypted with AES-256-GCM and stored locally in your browser. See our Security page for full details.
Yes. Import a wallet once into fees.fun and assign it as the deployer for as many platforms as you want.

​
Trading

No. Use RapidLaunch, Uxento, J7, or Axiom exactly as you normally do. fees.fun works in the background — you don’t need to change anything about your workflow.
Yes. fees.fun’s backend is deployed across multiple regions with multiple shards to ensure the quickest possible execution. Your trades go through our optimized infrastructure, which means they often execute faster than going through the platform directly — on top of costing less.
If fees.fun’s servers are unreachable, your transactions will fall back to the platform’s native system. You’ll pay the platform’s normal fee, but your trades won’t be blocked.
Yes. Import your sniper wallets into fees.fun (with the same addresses you use on the platform), and bundle buys are supported on RapidLaunch, Uxento, and J7.
Yes. The extension popup shows your total savings, per-platform breakdown, and recent transactions. See Fee Savings for more.
