What is a rug pull
and how to spot one

The scam

What is a rug pull?

A rug pull is an exit scam: a token's creators attract buyers, then take the money and abandon the project. The classic move is draining the liquidity pool so the token can no longer be sold, but a rug can also be a slow dump of the team's allocation, a sudden supply mint, or disabling sells outright.

The common thread is control. When a deployer keeps the keys (unlocked liquidity, a large token stash, mint authority, or owner-only functions), they can remove the value at any time. Spotting a rug is about checking who holds that control before you buy, because once the funds move on-chain they are almost never recoverable.

Know the playbook

Types of rug pull

Liquidity pull (hard rug)

The deployer removes the liquidity pool in one transaction. The token instantly becomes unsellable and the price collapses to zero. The fastest and most common rug.

Sell disable / honeypot

Buying works but selling is blocked via a blacklist, 100% sell tax, or a trading flag. Buyers are trapped while the chart climbs.

Dev dump (slow rug)

The team holds a large token allocation and sells into buyer demand over hours or days, bleeding the price down without ever touching liquidity.

Mint-and-dump

The owner retains mint authority, inflates the supply at will, and sells the freshly minted tokens, diluting every holder.

Warning signs

Common rug pull red flags

Unlocked liquidity

The LP is not locked or burned and is held by the deployer. Nothing stops them from withdrawing it the moment enough buyers arrive.

Concentrated holdings

A handful of wallets (often the deployer and connected addresses) hold a large share of supply, pre-positioned to dump.

Active mint authority

The owner can still mint new tokens (an EVM mint function, or a Solana mint authority that is not revoked), letting them inflate and dump supply.

Ownership not renounced

Privileged functions (fees, pause, blacklist, upgrade) remain controlled by an active wallet rather than renounced or behind a timelock.

Anonymous, unaudited team

No verifiable team, no audit, and copy-pasted or unverified contract code: common to throwaway scam launches.

Hype with no substance

Aggressive paid shilling, urgency ("last chance"), and locked or freshly-created socials, with no real product or traction behind the token.

Step by step

How to check a token for rug risk

01

Check liquidity lock and depth

Confirm the LP is locked or burned, for how long, and that it is deep enough to matter. Unlocked deployer-held liquidity is the single biggest rug vector.

02

Check holder distribution

Look at the top holders. If the deployer or a few wallets hold a large percentage, a coordinated dump can tank the price regardless of liquidity.

03

Check supply controls

Verify mint authority is revoked (Solana) or there is no owner-callable mint (EVM), so the supply cannot be inflated out from under you.

04

Check ownership and permissions

Is ownership renounced or behind a timelock or multisig? Active owner powers (fees, pause, blacklist, proxy upgrade) are all post-launch rug levers.

05

Scan the full contract

Resolve all of the above into one verdict (liquidity, distribution, supply, ownership, and sell-simulation) instead of checking each by hand.

What a verdict looks like

One scan, every signal

Instead of inspecting liquidity, holders, and permissions separately, XemaS resolves them into a single evidence-backed verdict.

Verdict: unlocked liquidity, concentrated supply, and active mint authority. The deployer can exit at any time. Coordinated-exit risk is high. Do not enter.
