# Guaranteeing a Fixed Supply of NFTs
|
||
|
||
For some projects, you might want to guarantee that no more than a fixed number of NFTs are minted from an issuing account.
|
||
|
||
To guarantee a fixed number of NFTs:
|
||
|
||
1. Create and fund a new account, the _Issuer_. This account is the issuer of the tokens within the collection. See [Creating Accounts](../../accounts/index.md#creating-accounts).
|
||
1. Use `AccountSet` to assign your operational wallet as an authorized minter for the issuer. See [Authorizing Another Account to Mint Your NFTs](authorizing-another-minter.md).
|
||
1. Use your operational account to mint the tokens using `NFTokenMint`. The operational wallet holds all of the tokens minted for the Issuer. See [Batch Minting](batch-minting.md).
|
||
1. Use `AccountSet` to remove your operational wallet as an authorized minter for the Issuer.
|
||
1. “Blackhole” the Issuer account. See [Disable Master Key Pair](../../../tutorials/how-tos/manage-account-settings/disable-master-key-pair.md).
|
||
|
||
At this point, it is impossible for any new tokens to be minted with the issuer’s address as the issuing account.
|
||
|
