If you’re only supporting a project on if,
👉 you don’t need to register any bank account information.
Bank details are required only for creators who launch and receive funds from their own projects.
On your My Page (マイページ → 登録情報の確認・編集),
you may see a section for entering bank account information.
However, if you’re using the site as a supporter,
you can safely leave this section blank — it is not required.
When a crowdfunding project succeeds,
the total support amount is first held temporarily by if.
After deducting service fees,
the remaining balance is transferred to the creator’s registered bank account.
Therefore, creators must register their account information
to ensure smooth and accurate fund transfers.
