Fees and the SOL you need

Every tool that spends your SOL runs on Solana mainnet only, so each action is real and on-chain. There is no devnet mode to switch the tools into, but the free Devnet Faucet fills a devnet address with test SOL, so you can rehearse a flow there before spending anything real. Before you start you want a little SOL in your wallet to cover what it costs.

Caution

About fees. Every action has two costs: the Solana network fee paid to validators, and the J Tools platform fee. The platform fee always shows in the app before you confirm, and nothing is charged until you sign. Fees can change over time, so trust the in-app summary rather than a number you saw once.

What you actually pay

#what-you-actually-pay

Two costs come out of your wallet in the signed transaction: the network fee on anything that touches the chain, and the platform fee on paid tools. A third, rent, applies whenever a tool creates a new account. All of them show before you sign.

Cost	Goes to	What it is
Network fee	Solana validators	The on-chain charge to process your transaction, sometimes called gas. Set by Solana, not by us. It ticks up with a small priority fee when the chain is busy.
Platform fee	J Tools	The fee for using the tool, set per tool. Some tools (like Token Burner) carry none, and the claim tools take a percentage of what you claim.

• Network fee Solana validators
• Platform fee J Tools, per tool
• Account rent stays in the account: token mint, metadata and associated token account

• Network fee still applies to anything that touches the chain
• Platform fee none, as on Token Burner
• Account rent not charged when no account is created

Not to scale. The strip shows which costs this transaction has, not how much each is; the amounts are on the fee card.

We estimate the network fee so the total on the fee card is close to the real cost, but validators set the final number. The platform fee is exactly what the card shows, and the amount we record comes from our own settings or from the transaction on-chain, never from a figure sent by your browser.

Note

Which tools are free, and what the claim tools such as Creator Fee Claim and Token-2022 Tax Collector take, is on the Fee schedule. The small Solana network fee still applies to anything that touches the chain.

Nothing is charged until you sign

#nothing-is-charged-until-you-sign

If the total on the fee card looks wrong, stop. Closing the tab or declining the wallet popup costs you nothing, and the transaction your wallet shows you is the one that gets sent.

Account rent is a deposit, not a fee

#account-rent-is-a-deposit-not-a-fee

The third thing that draws SOL is rent. When a tool creates a new account for you (a token mint, a metadata account, an associated token account), Solana asks that account to hold a minimum deposit, the rent-exempt minimum, so it stays alive on-chain.

This is not spent, but you only get it back for accounts you can actually close. Empty token accounts close and return their rent. A mint account and its metadata account stay open for the life of the token, so that deposit stays locked.

Note

Empty token accounts pile up as you trade and receive airdrops, each holding a bit of your SOL. Reclaim it any time with the Close Account tool, which finds empty accounts and sends the rent back to you. It keeps a small 5% cut of the reclaimed rent, so you still come out ahead in SOL.

How much SOL to keep on hand

#how-much-sol-to-keep-on-hand

Keep a small buffer beyond the cost of the single action you are about to run. Network fees are tiny and rent for a typical mint is modest, though that mint rent stays on-chain. What trips people up is having too little to cover all three at once, plus the priority fee when the network is busy.

1. Check the fee card first

   It shows the platform fee and estimated network fee before you sign.

2. Add a buffer for rent and priority

   Creation tools need rent for new accounts, and a busy network adds a small priority fee. Keep a little extra so the transaction does not fail for being a hair short.

3. Top up for batches

   Bots, multi-wallet sends, and bundled trades repeat the cost per action. Fund for the whole batch, not one row.

A transaction that fails for low SOL costs you nothing. The action simply did not go through.
