Questions people ask

Why do I need more SOL than my buy amount?

A buy also pays the curve fee, network and priority fees, and rent for your token account the first time you buy.

How much buffer should I keep?

A few hundredths of a SOL covers most buys, more if your bot sets high priority fees or tips.
