Chase says 50% of all fraud-related claims circle back to the company’s Zelle customers engaged in transactions on social media.

Chase Bank is going to make it harder to use Zelle for transactions stemming from social media. In an update to its policy on Zelle, Chase says it may “decline or block” payments related to purchases from social media marketplaces or messaging apps, as spotted earlier by Bleeping Computer.

JPMorgan Chase Bank (Chase) will soon start blocking Zelle payments to social media contacts to combat a significant rise in online scams utilizing the service for fraud.

"If you are sending a Zelle payment from your Chase account that is identified as originating from contact through social media, we may, in our discretion, delay, decline, or block that payment," according to a revised Zelle service agreement first spotted by BleepingComputer.

Scams on Zelle, the digital payments app, have apparently gotten so widespread that Chase Bank is moving to block users from sending payments to social media contacts. Chase updated its user policy, indicating it may block these sorts of payments.
