Solana Bundle Checker for pump.fun and Stonk launches
Last updated 2 October 2026
Paste a Solana token address to see whether its launch was bundled. GateKept rebuilds the block the token was created in, finds every wallet that bought with the create, and shows how much of the supply the developer and those wallets took, where their SOL came from, which launch team ran it and every wallet the supply was handed on to. It is free and needs no wallet.
In the last hour GateKept checked 1.9K new launches and found 353 of them bundled. 8.3K launch teams are mapped so far.
How do I check if a token is bundled?
Copy the token's contract address, paste it above and press Check. The launch opens in the Bundle Tracker with its bundle, funding, team and hand-offs. You can also search several tokens at once by separating their addresses with commas.
What is a bundled launch?
A bundled launch is one where a group of wallets, usually controlled by the developer or a bundling service, buys a large share of a new token's supply in the same block it is created, before anyone else can. A Solana block lasts about 400 milliseconds, so these buys are submitted together (typically as a Jito bundle) and land right behind the create.
The point is to own supply at the lowest price while the chart looks like organic demand. Bundle wallets often pass their tokens on to fresh wallets within seconds, so the holder list later looks spread out even when one team controls it.
How does GateKept detect bundles?
Most checkers look at one transaction or one block. GateKept follows the launch from the block it was created in to the wallets that end up holding it:
- The launch block
- Every buy placed directly behind the create is read, including buys that pay for several wallets in one transaction and a developer buy sent as its own transaction. Pools, vaults and other program accounts are left out, so only real wallets count.
- Organic-mode squads
- Some bundlers skip the launch block and buy over the next few seconds instead. GateKept reads every block on Solana and spots these squads by the setup their transactions share, so a launch that looks unbundled to a same-block checker is still flagged.
- Funding
- The SOL that funded the developer and bundle wallets is traced back through its hops to a root wallet or an exchange, with how long before the launch it arrived.
- Hand-offs to holder wallets
- Bundle wallets often sell into a throwaway account while a fresh wallet buys the same amount back in the same slot. GateKept pairs these sales and buys and shows every team wallet the supply went through, with what each still holds.
- Launch teams
- Launches that share a developer, bundle wallet, funding root or hand-off wallet are joined into a team, so you see the team's track record: how many tokens it launched, their all-time highs and how many graduated.
- Bought wallets
- Aged wallets sold on wallet marketplaces are tagged, since their history says nothing about who uses them now.
How do I read the results?
- Launch supply
- The share of total supply the developer and bundle wallets took at launch. A few percent across one or two wallets is common even on organic launches; a large share spread across several wallets funded from the same root is a coordinated launch.
- Still held
- How much of that supply the team's wallets, including the ones it was handed to, still hold. Supply that is still held can still be sold into buyers.
- Funding
- Bundle wallets funded minutes before the launch from one root, often through several hops, point to one operator.
- Team history
- A team with many launches and low all-time highs has a pattern; its next launch is likely to follow it.
Why do bundle checkers disagree about the same token?
Checkers count different things. A tool that reads only the create transaction misses bundle wallets that bought right behind it; one that counts every account whose balance went up counts pools and fee accounts as buyers; one that only maps holder clusters sees the wallets that hold now, after the bundle has been handed on. The table shows what each approach can see.
| What is detected | Create transaction only | Same-block count | Holder cluster map | GateKept |
|---|---|---|---|---|
| Buys behind the create, in the launch block | No | Yes | Partly | Yes |
| Wallets bought for in someone else's transaction | No | Sometimes | Partly | Yes |
| Pools and program accounts left out | Yes | No | Yes | Yes |
| Organic-mode squads (no launch-block buys) | No | No | Partly | Yes |
| Funding traced through hops | No | No | Yes | Yes |
| Supply handed on to fresh holder wallets | No | No | Partly | Yes |
| The team's earlier launches | No | No | No | Yes |
Which launchpads and chains does it cover?
pump.fun and Stonk on Solana, and Pons on Robinhood Chain. Every new launch on them is read as its block lands; launches recorded since February 2025 can be searched by ticker, name or address. For any other token, the token search shows its insider wallets, top traders and chance of being a cabal coin on Solana, Ethereum, Base and BNB Chain.
Questions
Is the GateKept bundle checker free?
Yes. Checking a token is free, needs no wallet connection and no account. An account only adds a watchlist and alerts.
Does a bundled launch mean the token is a scam?
No. A bundle means a few wallets took a large share of the supply at the launch price, so they can sell into later buyers. Some teams hold, some sell within minutes. What the bundle wallets still hold, where their funding came from and what the same team did on its earlier launches tell you more than the bundle alone.
Can I check a token that launched days or weeks ago?
Yes. GateKept keeps every launch it has recorded since February 2025, bundled or not. A pump.fun or Stonk token that is not in the archive is looked up on chain from its creation block when you paste its full address.
Does it still work after the token graduated to PumpSwap or Raydium?
Yes. The bundle is read from the block the token was created in, so it does not matter where the token trades now.
What is an organic-mode bundle?
A bundle that avoids the launch block. Nobody buys with the create, so the launch looks unbundled to a same-block checker; a squad of wallets then buys one by one over the next few seconds. GateKept finds these squads by the setup their transactions share and labels the launch Organic.
What is a launch team?
The people behind a series of launches, found through wallets they reuse: the same developer, bundle wallets, funding root or hand-off wallets across launches. A team shows how many tokens it launched, their average and median all-time high and how many graduated.
How quickly are new launches checked?
Seconds after their block lands. The Bundle Tracker reads every block on Solana, so new pump.fun and Stonk launches appear in its feed as they happen, and their funding and hand-offs fill in over the following minutes.
Can I be alerted when a team launches again?
Yes. Add a launch team to your watchlist and GateKept sends an alert by browser notification or Telegram when one of its wallets is funded for a new launch and when the launch lands.
