Changes apply to all future actions using the selected preset. The sections below use BSC as reference. The same logic applies to all supported EVM chains, although some features may vary depending on the chain. {% endhint %} *** #### How to Access Settings {% stepper %} {% step %} Click your account name in the top right corner of the Manager. {% endstep %} {% step %} Select Settings from the dropdown menu. {% endstep %} {% step %} In the Settings modal, select an EVM chain (Ethereum, Base, BSC or Robinhood) from the blockchain dropdown in the top right corner. {% endstep %} {% endstepper %} The Settings modal is organized into sections accessible from the left sidebar: **Spot Buy/Sell**, **Currency**, **Custom Theme**, **Token Blacklist**, **Extension** (Scrapers, Limit Orders, Dev Sell, Appearance), **Tracker** (Feed Settings, Keywords, Deploy Settings, Deploy Presets), and **Presets** (Defaults, Buy Amounts, Sell Amounts, Copy Preset, AFK Preset, Twitter Preset).
