When you create your Multisig Account, you are required to choose the co-signers you want to include. You can easily add or remove co-signers during this initial setup process. However, once your account is created, you will need to contact our support team to make any changes to your co-signers. This is because the Multisig Account is designed to provide maximum security for your funds, and changing or removing co-signers after the account has been created could potentially compromise that security. Our support team will work with you to make sure that any changes are made safely and securely.
