Token supply with the mint authority set to none
Mint authority controls who can mint new tokens of an SPL token. A revoke calls the token program's SetAuthority instruction and sets that authority to none. From then on, no wallet, Tokenry's included, can add to the supply, though holders can still burn their own tokens. The guide to what revoking mint authority means covers the term in depth.
Both Solana token programs are supported, SPL Token and Token-2022. The SPL Token CLI command spl-token authorize <MINT_ADDRESS> mint --disable, shown in the SPL Token docs, sets the same authority to none.
