Smithii Tools are paid per action: you pay a Smithii fee when you use a tool, and you see the amount before you sign. This page explains what you pay, which wallets you use on each ecosystem and the good practices that keep your funds safe. ## How Smithii fees work * **One fee per action.** Each paid action (create a token, revoke an authority, create a pool, send an airdrop…) has its own Smithii fee. Optional extras add their own fee on top. * **Native currency.** The fee is charged in the chain's native currency: SOL, ETH, POL, AVAX, BNB, MON, HYPE, TRX, SUI or NEAR. On **Arc** it is charged in **USDC**. See the currency of each chain in [Supported chains and tools](/overview/supported-chains.md). * **Shown before you sign.** The form shows the total Smithii fee before you sign, usually as "Total Fees". Bots show a quote with three figures: the Smithii fee, the bot deposit and the total. Most tools read the price live from Smithii's payments contract on each chain. * **Gas is separate.** The network gas goes to the network. Smithii does not charge it or control it. * **Prices change.** Each tool page lists its fees, checked on 2026-10-26. The tool always shows the exact amount before you sign. ### What is not a Smithii fee Some tools add network or third-party costs. They are part of the total you need in your wallet, but they don't go to Smithii: | Cost | Where you see it | Who charges it | | -------------------------------------------------------------- | ----------------------------------- | ------------------------------------------------------------------------------ | | Network gas | All chains | The network | | Rent for new accounts (token, metadata, pool, market accounts) | Solana | Solana | | Jito tips for bundles | Some Solana tools (bundles, snipes) | Jito | | Energy and bandwidth | TRON | The TRON network | | Storage deposit | NEAR | The NEAR network (it stays in the token or account) | | Swap fee of the pool | Pools on every DEX | The DEX and its liquidity providers | | Bot deposit | Volume bots and other bots | Not a cost: it funds the bot's trades, and what is left returns to your wallet | {% hint style="info" %} On Hyperliquid, a few tools first send 0.1 HYPE from your wallet to your own HyperCore account if it has never been used. That HYPE is still yours. {% endhint %} ### When the fee is charged * **In the same transaction.** In most tools the Smithii fee is part of the same transaction as the action. If the transaction fails, you don't pay the Smithii fee (you may still pay network gas, and on TRON the energy used). * **In a separate transaction first.** A few tools charge the fee in a separate transaction before the main action, for example the [OpenBook Market Creator](/products/tools/solana/token-tools/liquidity-pool/openbook-market.md), a Raydium V2 pool in the [Liquidity Pool on Solana](/products/tools/solana/token-tools/liquidity-pool.md), or loading recipients from NFT or token holders in the [Token Multisender](/products/tools/compare/token-multisender.md). If the later step fails, that fee is not refunded automatically. Each tool page says which case applies. ### Free tools These tools have no Smithii fee: * [Rug Check](/products/tools/compare/rug-check.md), on every chain. It is read-only and needs no wallet. * [NFT Hashlist](/products/tools/solana/nft-tools/hashlist-nft.md) on Solana. It is read-only and needs no wallet. * The Launches List, in [Presale, Launches List and Claim Site](/products/tools/solana/token-tools/token-launchpad.md). * Locking liquidity from the pool panel on EVM chains and TRON. See [Liquidity Pool](/products/tools/compare/liquidity-pool.md). ### Presales The [Solana presale](/products/tools/solana/token-tools/token-launchpad.md) works differently: on top of the creation fee, Smithii takes 2.5% of each purchase, paid by the buyer inside the purchase transaction. ## Wallets by ecosystem You connect your own wallet and sign from it. Connecting a wallet never requires its private key: you approve each transaction in the wallet itself. | Ecosystem | Wallet you connect | Good to know | | --------- | --------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | | Solana | A Solana wallet | Many tools list the tokens your wallet holds. To manage a token, connect the wallet that holds the authority (mint, freeze or update). | | EVM | An EVM wallet on the right network | If your wallet is on another network, the tool asks you to switch (the button reads "Switch to \"). On Arc you need USDC for gas. | | TRON | TronLink, Coinbase Wallet or any wallet compatible with WalletConnect | Your wallet must be on TRON Mainnet. | | Sui | A Sui wallet | Keep extra SUI for gas on top of the Smithii fee. | | NEAR | HOT, Meteor or another wallet from the selector | Some actions add a storage deposit to the total. | Read-only tools such as Rug Check and NFT Hashlist don't need a wallet at all. ## Wallets you import with a private key Some tools need several wallets to act at the same time, so they ask you to paste the **private keys** of extra wallets: * the [Bundler, Bundle Buy and Bundle Sell](/products/tools/compare/bundler.md) tools (sniper wallets and, in some launchpads, the wallets that buy or sell; on Four.meme, the creator wallet too), * the snipe option of the [Liquidity Pool](/products/tools/compare/liquidity-pool.md) on Solana, EVM chains and Sui. In most of these tools, the keys you paste are used **in your browser** to sign the buys and sells locally, and only the signed transactions are sent to the network. Use these options only with new, disposable wallets funded with the exact amount. Never paste the key of your main wallet or of a wallet with other funds. Even when keys stay in the browser, pasting a private key is always sensitive: anyone with access to your device, or a malicious browser extension, could read it. ## Bots and service wallets Volume bots and similar bots ([Volume Bot](/products/tools/compare/volume-bot.md), [Pump.fun Buy Holders](/products/dev-bots/pump-fun-bots/buy-holders.md), [Pump.fun Micro Trading](/products/dev-bots/pump-fun-bots/micro-trading-bot.md) and the connected-wallet mode of [Anti-MEV](/products/dev-bots/pump-fun-bots/anti-mev-volume-bot.md)) work in a different way: * You pay the Smithii fee and a **bot deposit**. The deposit goes to a wallet of Smithii's bot service, which uses temporary wallets to trade. * The bot does not get access to your own keys, but while it runs the deposit is not in your wallet. * What is left of the deposit returns to your wallet when the bot finishes or when you stop it. What is spent goes to trades, network gas and DEX fees. ## Good practices * **Use dedicated wallets for private keys.** Create new wallets for bundles and snipes, and send them only what they need. Never paste the key of your main wallet. * **Keep the files you download.** If a tool generates wallets for you (for example "Save Generated PKs" in the Solana bundlers), store that file safely: whoever has it controls those wallets. * **Review before you sign.** Check the token address, the amounts, the recipient list and the total. Transfers, airdrops, revocations and burns are irreversible. * **Check the network.** Make sure your wallet is on the chain of the tool before you sign. * **Don't resend blindly.** If part of an airdrop shows as failed, check the transactions in the block explorer before you send again, so nobody gets paid twice. * **Check a token before you buy it.** Use the free [Rug Check](/products/tools/compare/rug-check.md) to see its authorities, taxes and liquidity. * **Verify the contracts.** The Smithii contracts on each chain are listed in [Smart Contracts](/products/smart-contracts.md), and the audits are in [Audits](/overview/audits.md). * **Large batches and hardware wallets.** Some tools ask you to approve hundreds of transactions at once. Some hardware wallets may not support that many in one approval. ## FAQ ### Is the gas included in the Smithii fee? No. The Smithii fee is only Smithii's charge. Network gas, and costs such as Solana rent or TRON energy, are paid separately. ### Where do I see the exact fee? In the tool, before you sign. Each tool page also has a "Fees" table, checked on 2026-10-26. ### Do I get the fee back if the transaction fails? If the fee is part of the same transaction, a failed transaction does not charge it. If the tool charges the fee in a separate transaction first, it is not refunded automatically. Each tool page explains which case applies. ### Does Smithii hold my funds? In most tools, no: you sign from your wallet and the result goes to your wallet. Bots are the exception: the bot deposit goes to a service wallet while the bot runs, and the rest returns to you. ### Why does TRON show such a high fee limit in my wallet? That figure is the maximum the network could burn for the transaction, not what you pay. See the TRON tool pages for details. ## Related * [Supported chains and tools](/overview/supported-chains.md) * [Tools](/products/tools.md) * [Best Security Practices for Solana](https://smithii.io/en/best-secure-practices-solana/) * [Best Solana Wallet](https://smithii.io/en/best-solana-wallet/)
