Mainvest requires bank linkage in order to securely process investments and repayments. We recommend using Plaid to link your account, but if you don't have online banking credentials or prefer not to provide them, you are able to link your account by sending us a picture of a voided check.

  1. Write "Void" onto a check to the account you wish to use.

  2. Take a picture of that check.

  3. Attach the image to an email and please send to with your name and email so that we can verify your account.

Once you send this through, we will confirm that we've linked up your account. The process takes just a few minutes, so this is a feasible option if you're looking to invest very quickly (for example, if an offering closes in a few hours).

Reach out to with any questions.
