What Plaid changes
Plaid acts as the account-linking layer between the user and the product. In Hasanah's public disclosures, that means account linking, verification, and transaction analysis depend on Plaid rather than on Hasanah building those flows alone.
Why donors care about that
A donor usually wants to know whether a charity product is asking for bank credentials directly or using a specialized provider. In Hasanah's case, credentials are handled by the account-linking provider, which is a more credible answer than vague security claims.
What Plaid does not answer by itself
Plaid does not answer fee questions, campaign routing, failed withdrawal handling, or receipt workflows. Those still depend on Hasanah's own product terms and policies, so donors should review both the infrastructure layer and the service rules.
