Hard rug

Also written or said as: liquidity pull, lp pull, pulled liquidity, pulled lp

A rug that leaves holders unable to get their money out: the pool is pulled, new tokens are printed or accounts are frozen.

It needs a switch the creator kept: the LP tokens of a pool they built, the mint authority, the freeze authority, or an extra setting like a permanent delegate. pump.fun switches these off for every coin and burns the LP tokens when a coin graduates, so a crash there is usually a soft rug, insiders selling into buyers. Some traders call any sudden dev dump a hard rug; this guide calls that a soft rug. Revoked authorities and burned or locked LP, checked before you buy, are the defence.
