---

Steps

1. Initiation: The KYC verified Investor navigates to the "Wallet" section of the Investor Dashboard and chooses the option to "Link a Bank Account."

2. Provider Integration: The Integrated Wallet Solution initiates the process with the bank linking provider (Plaid). The Investor Dashboard presents the Plaid Link interface to the Investor.

3. Bank Authentication: The Investor securely selects their bank and authenticates using their online banking credentials within the Plaid interface.

4. Account Selection: The Investor selects the specific bank account (e.g., Checking) they wish to link.

5. Token Exchange: Plaid securely returns authentication tokens to the Integrated Wallet Solution.

6. Funding Source Creation: The Integrated Wallet Solution exchanges the Plaid tokens with the payment provider (Dwolla) to create a verified FundingSource. It stores the relevant details (bank name, last 4 digits, provider ID) in the FundingSource data model, linked to the user's Wallet.

7. Confirmation: The Investor Dashboard displays the newly linked bank account to the Investor.

8. Outcome: The investor's external bank account is securely linked as a FundingSource and can now be used for deposits or withdrawals.
