Is a dev selling always bad?

A small sell to cover costs is normal. A dev selling a large share into a pump is the dump you were warned about.

What if the dev wallet shows zero tokens?

Check whether the supply moved to other wallets. A dev can hide a share by spreading it into a bundle.

Can the dev wallet rug a migrated coin?

Only if they still control the liquidity. If it is burned or locked, a liquidity pull is not possible, though a dev dump still is.

Dev wallet: why the creator's holdings matter

The dev wallet is the wallet that created a coin. It often still holds a large share of the supply, and what that wallet does next is one of the biggest risks to anyone who buys.

What is a dev wallet?

Every coin on Solana is created by a wallet. People call it the dev wallet, short for developer, even when no real development happened. On a launchpad like pump.fun, creating a coin takes a minute and a few cents.

The creator usually buys first, often in the same transaction that launches the coin. That gives the dev wallet the cheapest tokens anyone will ever hold.

Why does the dev's share matter?

A dev holding 2% of supply can sell without moving the price much. A dev holding 40% can crash the coin in one transaction. That second case is called a dev dump, and it is one of the three common rug pull shapes.

A dev holding more than 10 to 15% of supply is a warning sign. It does not mean a dump is coming. It means a dump is possible at any second, and you should size your position as if it might.

What should you check?

Before you buy, look at the dev wallet on an explorer or a chart site like DexScreener.

How much supply does the dev hold right now? Has it been sold, moved or spread across other wallets?
What did this wallet do before? A history of coins that launched and died within hours tells you what to expect.
Is the dev adding liquidity or pulling it? On migrated coins, is the liquidity locked or burned?
Do the dev's other wallets form a bundle? One person can control many addresses.

How MemeSim teaches it

MemeSim's Rug pulls lesson explains the dev dump with examples and a quiz, and the simulator lets you watch a dev-heavy coin play out with fake SOL. When a coin dies, the red explainer on the coin page points to the signs that were there, including a large dev share.

The habit to build is simple. Read the holder list before every buy. If the dev's share makes you nervous, buy less or skip it.
