What is bundling in crypto?
Bundling means 1 party buys a new token from 2 or more wallets in the same block, so the supply looks spread out while one party holds it. On KABOOM!, a bundle launch puts the dev-buy and up to 2 vault wallets in one transaction and lists every bundle wallet on the coin page.
How bundling works on Solana
A bundle is a set of buys that land together. On Solana there are two ways to do that. The first is one transaction with several signers: the maker and a few extra wallets all buy inside it, so the buys succeed or fail as one. The second is several transactions sent together to a block builder, which places them in the same block in a fixed order.
Either way the result on a new token is the same: in the very first block, before anyone else can react, a handful of wallets already hold a large share of the supply. If one person controls all of them, the token is far less spread out than its holder list suggests.
Why makers bundle a launch
- Price. On a bonding curve the first buys are the cheapest. Buying from five wallets in the launch block gets the maker more tokens per SOL than anyone who comes later.
- Looks. One wallet with a quarter of the supply scares buyers off. Five wallets with a few percent each look like an organic start.
- Exit. Spread over several wallets, the tokens can be sold in smaller pieces that draw less attention, or all at once.
Not every bundle is a trap. A maker can simply want a bigger starting position and say so. The problem is the hidden bundle: wallets that pretend to be strangers.
How to spot a bundled launch
Open the token on a block explorer and look at the first block of trading. These are the signs to check, roughly in order of how telling they are:
- Several wallets bought in the launch block or the next one, often in the same transaction as the maker.
- Those wallets were funded from the same source, minutes or hours before the launch.
- The wallets are new: no history before this token, or only a transfer in and this one buy.
- The buys are similar in size, or add up to a round share of the supply.
- Together they hold far more than any single holder on the list.
- Later, they sell within the same few minutes.
A bundle checker automates the first four steps: it groups early buyers by shared funding and timing and gives an estimate of how much one party may hold. It is an estimate, not proof. The rug pull checklist puts this next to the other checks that matter before you buy.
Bundle launches on KABOOM!
Bundle launches are open on Solana mainnet: the coin, the maker's dev-buy and buys from up to 2 of the maker's own vault wallets go in one transaction, with a 1% creation fee on the total buy (the same 1% a standard launch pays on its dev-buy), and the coin page lists every bundle wallet. A bundle launch here is declared, not hidden: the coin, the maker's dev-buy and up to 2 vault wallets go into one transaction that all of them sign. It lands as a whole or not at all. A bundle that does not fit in one transaction is refused, never split.
| Rule | Verified | Open bundle |
|---|---|---|
| Launch fee | None | 1 SOL |
| Maker and bundle buys together | Up to 30% of the supply, checked by the launch builder before you sign | No cap |
| Bundle wallets next to the dev-buy | Up to 2 | Up to 2 |
| Fee on the bundle buys | The fee of that second, from 50% | The fee of that second, from 50% |
| Creation fee | 1% of the dev-buy and the bundle buys | 1% of the dev-buy and the bundle buys |
| Maker vesting | 5% of the supply over 30 days | None |
The wallet limit is measured: one more wallet runs over Solana's transaction limits. The dev-buy, the first swap of the launch, pays the normal fee; the bundle buys after it pay the anti-sniper fee of that second. How the fee falls: sniper bots and the anti-sniper fee.
Every bundle wallet is listed on the Solana coin page, in the “bundled through this platform” layer of the disclosure badge. That layer is an on-chain fact, not an estimate: the wallets signed the launch transaction. The bundle layer of the disclosure badge is live; cluster figures are not live yet, so no cluster number is shown. How the badge works: method.
What a declared bundle does not tell you
It tells you who bought in the launch transaction. It does not tell you what they will do next. Bundle wallets can sell like any other wallet, and so can the maker's dev-buy. On a Verified launch, only the 5% maker allocation is locked by token vesting; the dev-buy and the bundle buys are not. After migration the pool itself cannot be pulled, because its liquidity is permanently locked (locked liquidity explained), but that does not stop anyone from selling into it.
Frequently asked questions
What does bundling mean in crypto?
Bundling means buying a new token from several wallets at once, controlled by one person or group. On Solana that is several buys inside one transaction, or several transactions sent together through a block builder so they land in the same block. On a new launch the maker often does it in the very first block.
Why is a bundled launch a risk for buyers?
Because the holder list lies. Ten wallets with a few percent each look like a spread-out launch, but if one party controls them all, that party can sell a large share of the supply at once. The price can drop hard, however healthy the chart looked.
How can I check if a token was bundled?
Look at the buys in the launch block: how many wallets bought, whether they were funded from the same source shortly before, and how much of the supply they took together. On KABOOM!, the Solana coin page lists every declared bundle wallet. The bundle layer of the disclosure badge is live; cluster figures are not live yet, so no cluster number is shown.
What is a bundle checker?
A bundle checker is a tool that groups early buyers by shared funding and timing and estimates how much of the supply one party may hold. It gives an estimate, not proof: linked wallets can be missed and unrelated ones grouped. On KABOOM!, detected clusters cover Solana mainnet coins only and are shown with their measured false-positive rate, once live.
Can I launch with bundle wallets on KABOOM!?
Bundle launches are open on Solana mainnet: the coin, the maker's dev-buy and buys from up to 2 of the maker's own vault wallets go in one transaction, with a 1% creation fee on the total buy (the same 1% a standard launch pays on its dev-buy), and the coin page lists every bundle wallet. A Verified launch has no launch fee and caps the maker and bundle buys at 30% of the supply; the launch builder checks that before you sign, not the on-chain program. An Open bundle launch pays 1 SOL and has no cap.
Do bundle wallets pay the anti-sniper fee?
Yes. Only the maker's dev-buy, the first swap of the launch transaction, pays the normal fee. The bundle buys land in the same second and pay the anti-sniper fee for that moment, which starts at 50%. The review shows that cost before you sign.
How many bundle wallets fit in one launch?
Up to 2 next to the dev-buy, as measured: one more wallet runs over Solana's transaction limits. A bundle that does not fit is refused, never split over more transactions, so the launch lands as a whole or not at all.
Does a declared bundle make a coin safe?
No. Declaring the wallets shows who bought, but bundle wallets can still sell. Maker vesting on a Verified launch covers the 5% maker allocation, not the dev-buy or the bundle buys.
