Total supply rules for an Arbitrum ERC-20 from Tokenry
The total supply of an ERC-20 deployed through Tokenry on Arbitrum One changes in three ways, each set by the features chosen at deploy. The mint feature adds tokens, up to the supply cap if one was set. The burn feature destroys tokens for good. A tax with a burn share burns part of every taxed trade, so supply can fall without any owner action.
No feature can be added after deploy, so a token without the mint feature needs a new contract to gain it. Renouncing ownership ends minting for good, and from then on supply can only stay level or fall. You can create a token on Arbitrum with mint, burn and a supply cap turned on.
