The aged-wallet trick: how a dev hides a bundle, and how to spot it
Short answer Launch tools now sell aged wallets so a dev can buy 12-15% of a new memecoin without it showing as a bundle. Here is the method, step by step, and the four checks that still catch it.
A public tutorial posted on X on 17 October walks new developers through launching a memecoin in about an hour for about $60. Most of it is ordinary: an AI-built website, an AI launch video, a paid checkmark on a new X account. The part that matters to a buyer is the last five minutes, where the developer buys a large share of the supply before anyone else can, in a way built not to show up as a bundle.
This post explains that method and the checks that still catch it.
The method, as the tutorial shows it
- Buy aged wallets. The launch tool has a marketplace of wallets for sale. The tutorial recommends five to ten, "minimum one day old", for about 0.24 SOL for five. An old wallet does not look like the fresh wallets that bundle checks flag.
- Fund them with a gap. One funder wallet sends to all of them, with a "funding gap" of at least 30 minutes, so the funding transfers do not land together. The tutorial says it plainly: if they are funded the same way, "it's gonna show that you're holding the whole supply, which is not good. People are not gonna buy on top of you."
- Split the buy. About 12-15% of the supply, spread across 10-14 holder wallets, bought in the launch block. The developer wallet itself buys 1% and locks it, because a locked dev share looks safe.
- Sell when it feels right. The tutorial's words. Nothing is locked except the 1%.
The tool supports Solana, Robinhood Chain and BNB Chain.
What a buyer sees
On the chart, nothing unusual. The token opens at a few thousand dollars of market cap and starts trading. The holder list shows a dozen wallets with similar balances, none of them large on its own, and a dev wallet with a lock. Each of those things on its own reads as healthy.
Four checks that still catch it
1. Same-block buyers. Aged or not, the wallets buy in the launch block. A dozen separate people do not all land in the first block of a token nobody has heard of yet. On a PumpPill read this is the "launch buyers" line: how many bought in the same block and how much of the supply they took.
2. Equal sizes. Look at the top 60 holders. When a large group holds near-identical amounts (on $CRAWLER, 59 of the top 60 holders each held between 0.10% and 0.16%), that is one buy split into pieces. Real buyers come in every size.
3. Trace the funders two steps back, not one. A funding gap hides the pattern in time, not in the graph. On $CRAWLER, 58 of the top 60 sellers had been funded by just two wallets, and both of those were funded by one private parent wallet with about a hundred transactions. One step back looked like two unrelated funders. Two steps back it was one person.
4. Old wallet, no history. An aged wallet bought from a marketplace is old but empty: created weeks ago, no activity until the funding transfer that lands just before launch. A real holder's wallet has a past. Open three of the top holders and look at their first ten transactions.
What a locked dev share means
Less than it looks like. In this method the dev share is 1% and the supply that matters sits in the holder wallets, unlocked. A lock on the dev wallet tells you about the dev wallet and nothing else.
Where our read falls short
We record funding transfers so we can link wallets, and batch funding spread over time is the hardest pattern to link. When a funder pays wallets through a contract that sends to many addresses at once, or in small amounts below what we record, our funder line can show "unknown" for wallets that are linked. We are adding those transfers. Until then, an "unknown" funder on a group of same-block, same-size holders deserves the two-step check above, done by hand.
The short version for a buy decision
A dozen wallets that bought in the first block, hold the same amount and have no history before their funding are one buyer. Treat their combined share as one wallet's share, and size your buy the way you would if one wallet held that much.
The basics of reading a launch are in how to tell a launch is bundled.
Paste any contract at pumppill.org for the launch-buyer, holder and funder lines, or open it on DexScreener with PumpPill Lens installed.
The lesson is the method. The product is where you apply it.
Paste any Solana or Robinhood Chain contract into the PumpPill trade bot: you get the risk read first, then buy or sell in one tap, with limit orders and auto-sells.
