Key takeaways
- As of November 5, 2026, Smithii's pump.fun bundler charges a flat 0.3 SOL per launch for up to 16 buyer wallets in a single Jito bundle, with an optional pre-generated mint address for 0.1 SOL more.
- Slerf Tools prices its pump.fun launch-and-buy per address, from 0.035 SOL per address at its lowest tier, for up to 16 addresses, according to its fee disclosure last updated December 26, 2025.
- SOLTidy's Pump.fun Bundle Launcher charges 0.3 SOL per bundle plus the Jito tip, for up to 16 buyers including the creator, and charges nothing if the bundle doesn't land.
- All three pump.fun bundlers rely on Jito bundles and say private keys are used to sign locally rather than collected.
- Every bundled pump.fun launch is visible on chain, because all bundled wallets buy in the coin's first block and screeners flag the bundled share of supply.
The short answer
As of November 5, 2026, Smithii and SOLTidy both charge a flat 0.3 SOL per pump.fun bundle launch with about 16 wallets in one Jito bundle, and Slerf Tools charges per address, from 0.035 SOL each. Smithii covers the most launchpads and generates wallets for you; Slerf can be cheapest for small bundles and runs on many chains; SOLTidy bundles more wallets on Bonk.fun and Jupiter Studio and charges nothing if the bundle fails. All three bundles are fully visible on chain.
How were these pump.fun bundlers compared?
I compared only bundlers whose pricing I could load on their own websites on November 5, 2026: Smithii, Slerf Tools and SOLTidy, which I build. Other tools exist, but where I couldn't load a vendor's own pricing page I left them out rather than repeat third-party claims. Prices are in SOL and exclude the SOL each wallet spends on its buy, pump.fun's 1.25% trading fee inside every buy and network fees.
How a bundle works is covered in how a pump.fun bundler works; this post is only about the tools.
How do Smithii, Slerf Tools and SOLTidy compare?
| Smithii | Slerf Tools | SOLTidy | |
|---|---|---|---|
| pump.fun bundle launch price | 0.3 SOL flat | From 0.035 SOL per address (tiered) | 0.3 SOL flat |
| What the price includes | "All fees needed for the launch", per its page | Excludes gas and Jito tips | Excludes the Jito tip (0.001 SOL default) |
| Wallets per pump.fun bundle | Up to 16 buyer wallets | Up to 16 addresses | Up to 16 buyers including the creator |
| Jito / same block | "In a single Jito bundle" | Relies on Jito bundling, "100% earliest buy" | One Jito bundle, in order, all or nothing |
| Charged if the bundle fails | Not stated | No fees on a failed attempt, per its docs | No: the fee is inside the bundle's create transaction |
| Buyer wallets | Generated in your browser, or use your own key for dev | Imported keys, one by one or in bulk | Pasted keys, signed in the browser tab and wiped |
| Vanity mint | Pre-generated address, +0.1 SOL | Not listed | Not offered in the bundler |
| Other launchpads | Bonk.fun, LaunchLab, Moonit, Jupiter Studio, StonkFun, Bags | BonkFun, LaunchLab | Bonk.fun, LaunchLab, Jupiter Studio |

Sources: Smithii's pump.fun bundler page; Slerf Tools' service fee disclosure (last updated December 26, 2025) and its pump.fun launch-and-buy guide; SOLTidy's Pump.fun Bundle Launcher. One inconsistency worth knowing: while I checked, Smithii's launch form displayed a total of 0.100 SOL even though its page text says 0.3 SOL, so confirm the figure in your wallet before you sign.
What does each bundler cost for a real launch?
Take a launch with a 1 SOL dev buy and 15 wallets buying 0.5 SOL each: 8.5 SOL of buys, about 23.5% of the supply on a fresh curve.
| Cost item | Smithii | Slerf Tools | SOLTidy |
|---|---|---|---|
| Tool fee | 0.3 SOL | ≈ 0.56 SOL at the lowest 0.035 SOL tier for 16 addresses | 0.3 SOL |
| Jito tip | Not listed separately; the page says 0.3 SOL covers all launch fees | Extra; its guide suggests 0.01 SOL when retrying | 0.001 SOL default |
| Buys (pump.fun fee inside) | 8.5 SOL | 8.5 SOL | 8.5 SOL |
| Token account rent, 16 wallets | ≈ 0.03 SOL | ≈ 0.03 SOL | ≈ 0.03 SOL |
For a full 16-wallet bundle, Smithii and SOLTidy cost about the same. Slerf's per-address model is likely to cost more for a full bundle and can cost less for a small one: three wallets at a per-address rate near the 0.035 SOL floor would be about 0.1 SOL. Its disclosure doesn't list the rate for each tier, so check the live quote.
Where do Smithii and Slerf Tools beat SOLTidy?
Both competitors do things SOLTidy doesn't, and for some launches that settles it.
Smithii generates the buyer wallets in your browser, so you don't have to create and fund keys elsewhere first, and offers a pre-generated vanity mint for 0.1 SOL. It has bundlers for Moonit, StonkFun and Bags, which SOLTidy can't create coins on, plus a volume bot (0.1 SOL per 100 makers, per its page) and "holder" buys. It also runs on many chains besides Solana.
Slerf Tools charges 0.05 SOL to launch on pump.fun without bundling, against 0.1 SOL for SOLTidy's pump.fun token launcher. Its per-address pricing favors small bundles, it offers a launch-plus-migration-buy product, and like Smithii it covers EVM chains.
Where does SOLTidy do better?
SOLTidy's advantages are in how many wallets fit on other launchpads and in what happens when a bundle fails.
- More wallets on Bonk.fun, LaunchLab and Jupiter Studio. Smithii's Bonk.fun and LaunchLab forms showed 4 wallets and its Jupiter Studio form 4. SOLTidy's Bonk.fun Bundle Launcher and LaunchLab Bundle Launcher take 8 wallets plus yours, and the Jupiter Studio Bundle Launcher 11 plus yours, each for 0.3 SOL.
- No fee unless it lands. The 0.3 SOL is a transfer inside the bundle's first transaction, so a bundle that doesn't land charges nothing, and a retry keeps the same mint address so it can't create a second coin.
- Prices quoted before you sign. Each wallet's tokens are quoted in bundle order on the curve, and the bundled share of supply is shown before launch.
- Cheaper mass sells for small runs. Smithii's bundle buy and sell are 0.1 SOL each. Pump.fun Mass Sell charges 0.5% of the SOL received, capped at 0.1 SOL per run, so selling 5 SOL from 16 wallets costs 0.025 SOL.
What SOLTidy doesn't do: it has no volume bot, no vanity mint in the bundler, no wallet generation inside the bundler (the separate Wallet Manager does that), no Moonit or Bags bundles, and only Solana.
How should you choose a bundler?
Choose by the launch you are doing, then verify the live price:
- A full 16-wallet pump.fun bundle: Smithii and SOLTidy are both 0.3 SOL; pick on key handling and the extras you want.
- A small bundle of a few wallets: check Slerf's per-address quote, which may be lower.
- Bonk.fun, LaunchLab or Jupiter Studio with more than 4 wallets: SOLTidy.
- Moonit, Bags or StonkFun: Smithii.
- Several chains in one dashboard: Smithii or Slerf Tools.
Whichever tool you use, the risk that matters most is keys. A bundler needs every buyer wallet's signature, and no vendor's promise about local signing can be verified from outside. Use fresh wallets funded with only what they will spend, and never paste a key that holds savings.
Is bundling honest?
It can be. Bundling is a way to buy your own coin from your own wallets at the launch price, atomically. It does not hide anything: every bundled wallet buys in the first block, and pump.fun's holder list, Solscan and screeners such as RugCheck, Bubblemaps and GMGN show and flag the bundled share. Disclose team wallets, keep the share reasonable, and don't use bundles to fake demand or to sell on buyers who don't know about them. That misleads people and, in many places, can break market manipulation and consumer protection laws. What is a Jito bundle explains why bundles are atomic but never private once they land.
Bottom line
On November 5, 2026, Smithii and SOLTidy both charge 0.3 SOL for a 16-wallet pump.fun bundle, and Slerf Tools charges per address from 0.035 SOL. Smithii wins on launchpad coverage, wallet generation and extras; Slerf on small bundles and plain launches; SOLTidy on wallet counts outside pump.fun and on charging nothing for failed bundles. Prices change, so check each live page, and remember that every bundled wallet is visible on chain.
Questions & answers
What is the cheapest pump.fun bundler?
It depends on how many wallets you bundle. Smithii and SOLTidy both charge a flat 0.3 SOL per pump.fun bundle launch as of November 5, 2026. Slerf Tools charges per address, from 0.035 SOL at its lowest tier, so at that rate 16 addresses would cost 0.56 SOL, while a launch with only a few wallets may cost less than 0.3 SOL depending on the tier. Check each live price before launching.
How many wallets can a pump.fun bundler use?
About 16. Smithii advertises up to 16 buyer wallets in a single Jito bundle, Slerf Tools up to 16 addresses, and SOLTidy up to 16 buyers including the creator. The limit comes from Jito's 5 transactions per bundle and Solana's 1,232-byte transaction size, which fits about 4 pump.fun buys per transaction.
Do pump.fun bundlers store my private keys?
All three say no. Smithii says sniping wallets are generated and signed in your browser and that it never has access to your keys. Slerf Tools says it only computes locally to sign and never collects or uploads keys. SOLTidy uses pasted keys only in the browser tab and wipes them after signing. You can't verify any of this from outside, so use fresh wallets that hold only what they will spend.
Which bundler supports Bonk.fun and other launchpads?
Smithii lists bundlers for pump.fun, Bonk.fun, LaunchLab, Moonit, Jupiter Studio, StonkFun and Bags. Slerf Tools lists launch-and-buy for pump.fun, BonkFun and LaunchLab. SOLTidy has bundle launchers for pump.fun, Bonk.fun, Raydium LaunchLab and Jupiter Studio, but not Moonit or Bags, whose launches require the platform's own signature.
Is a bundled launch hidden from buyers?
No. Bundled wallets all buy in the coin's first block, and pump.fun's holder list, Solscan and screeners such as RugCheck, Bubblemaps and GMGN show and flag the bundled share of supply. A bundler makes your launch buys atomic, not invisible, and using it to fake demand misleads buyers.
