mint_authority: Pubkey

The authority/multisignature to mint tokens.

freeze_authority: COption<Pubkey>

The freeze authority/multisignature of the mint.

Initializes a new mint and optionally deposits all the newly minted tokens in an account.

The InitializeMint instruction requires no signers and MUST be included within the same Transaction as the system program’s CreateAccount instruction that creates the account being initialized. Otherwise another party can acquire ownership of the uninitialized account.

All extensions must be initialized before calling this instruction.

Accounts expected by this instruction:

0. [writable] The mint to initialize.
1. [] Rent sysvar

InitializeAccount

Initializes a new account to hold tokens. If this account is associated with the native mint then the token balance of the initialized account will be equal to the amount of SAFE in the account. If this account is associated with another mint, that mint must be initialized before this command can succeed.

The InitializeAccount instruction requires no signers and MUST be included within the same Transaction as the system program’s CreateAccount instruction that creates the account being initialized. Otherwise another party can acquire ownership of the uninitialized account.

Accounts expected by this instruction:

0. [writable] The account to initialize.
1. [] The mint this account will be associated with.
2. [] The new account’s owner/multisignature.

The InitializeMultisig instruction requires no signers and MUST be included within the same Transaction as the system program’s CreateAccount instruction that creates the account being initialized. Otherwise another party can acquire ownership of the uninitialized account.

Accounts expected by this instruction:
