Set Authority Instructions

Changes the authority of a mint or account. This allows transferring ownership or updating specific authority types.

Before we can mint any token, we'll need to already have:

Initialized a Mint account which we hold the mintAuthority or freezeAuthority
Initialized a Token account or Associated Token account that we own

This is how the CPI to the set_authority() instruction looks like:

set_authority(
    CpiContext::new(
        ctx.accounts.token_program.to_account_info(),
        SetAuthority {
            account_or_mint: ctx.accounts.mint_account.to_account_info(),
            to: ctx.accounts.to_token_account.to_account_info(),
            current_authority: ctx.accounts.authority.to_account_info(),
        },
    ),
    &spl_token::instruction::AuthorityType::MintTokens, // authority_type
    Some(new_authority.key()) // new_autority
)?;
