What is a bundle in crypto?
A bundle is one party buying a coin’s launch through many wallets at once, so it looks like real demand. Here is what bundled, bundler and bundling mean, why people do it, and how to check any coin in a minute.
What the data shows
What is a bundle in crypto?
A bundle is a set of buys sent together, usually at the moment a new coin launches, from several wallets that one party controls. On Solana, transactions can be submitted as a group that lands in the same block, in a fixed order. Used at launch, this lets one party buy a large share of a new coin at the lowest price while it looks like many separate buyers got in.
What does "bundled" mean?
A coin or launch is called bundled when a big part of its supply went, at launch, to wallets that appear to be linked: they bought in the same block the coin was created in, one transaction bought for several of them, or the same wallet funded them shortly before. The holder list looks spread out, but much of it may answer to one party.
What is a bundler?
The word is used two ways. A bundler is the person or wallet that bundles a launch. It is also the name for the software that automates it: tools that create a coin and buy it from dozens of wallets in the same block, fund those wallets through exchanges so the links are harder to see, and can sell automatically into new buyers. Proxima is one of the tools people use for this.
Why do people bundle a launch?
Three reasons: to own a large share at the lowest price, to make the coin look popular (many holders, steady buying), and to sell into the people who buy after them. In one launch we documented, three wallets bought 13.4% of supply in the coin’s creation block, and the creator sold slices right after outside buys.
Is a bundle always a scam?
No. Some creators buy openly at launch, and pump.fun shows that buy. The warning sign is hiding it: many wallets that look independent but trace back to one source. Also watch for the opposite trick, a single wallet buying most of the supply. In the KIMCHI launch the creator bought 79.31% in the first transaction, with no crowd to detect at all.
Bundle vs sniper: what is the difference?
A sniper is a fast trading bot that buys a new coin in its first seconds. Snipers are usually independent of the creator. A bundle is a group of wallets that are linked to each other or to the creator. Buying in the same second is not proof of a bundle on its own, because bots do that on most launches: the link is in who funded the wallets and where they landed in the block.
How do I check if a coin is bundled?
Look at three things: the creation block (did other wallets buy right behind the creation transaction?), the funding of the first buyers (did one wallet, an exchange batch or the creator fund several of them?), and today’s top holders (do linked groups hold a big share now?). Paste the coin into the unbundle Bundle Check to see all three in plain English, with every transaction linked.
Why do different sites show a different bundle %?
Because they answer different questions: how much was bought in bundles at launch, how much those wallets still hold, or how much linked groups hold right now. One coin we checked showed 0%, 7.7%, 13.4%, 32%, 33.7% and 59% on different sites, and each number was "right" for its own question.

Limitations
- •Definitions follow how the words are used in Solana memecoin trading as of October 2026; usage on other chains can differ.
- •Bundle signals are a reason to look closer, not proof of who controls a wallet. On-chain data cannot establish identity.
- •The examples come from our own verified case studies; see each study for its transactions and limits.
Check it yourself
Paste any Solana coin into the Bundle Check at unbundle.fun/bundle. It reads the creation block, traces who funded the first buyers and groups today’s holders, with a link to every transaction.
