Denver, Colorado Dec 11, 2025 (Issuewire.com) - E-commerce fraud is evolving, but the tools to fight it have remained stagnantuntil now. Blox, a new SaaS startup, has launched an advanced fraud prevention solution on the Shopify App Store. Blox: Chargeback Blacklist introduces customer deduplication engine that creates a permanent connection between a bad customer's email, shipping address, and credit card, effectively stopping repeat offenders who attempt to evade bans by changing a single detail.
For Shopify merchants, the standard method of blocking a customer involves blacklisting an email address or other pieces of information. However, sophisticated fraudsters and serial returners circumvent this by simply using a different email address while using the same physical address or credit card.
Blox solves this "whack-a-mole" problem. It is currently the only solution on the Shopify App Store that automatically links all customer identifiers. If a merchant blocks a fraudsters email, Bloxs algorithm instantly flags and blocks any future orders associated with that persons address or credit card regardless of the email used.
"Merchants are tired of blocking a bad actor only to see them return ten minutes later with a new Gmail account," said Conor Parrish, Co-Founder of Blox. "We built Blox because existing tools were treating fraud as a list of bad emails, rather than a network of bad actors. Our technology de-duplicates these identities. You block the person once, and they are blocked forever."
Key Features of Blox include:
- Smart Identity Linking (De-Duplication): The core engine that connects emails, credit cards, and addresses. Blocking one data point blocks the entire web of data associated with that user.
- The Global Blacklist: A community-driven database. If a customer has been blocked on other Shopify stores using Blox, or has issued chargebacks elsewhere, they are automatically flagged before they can damage your business. A common use case is blocking someone testing stolen credit cards.
- "Money Keep Rate" Scoring: A unique rating system that evaluates how "good" a customer is based on the percentage of money the merchant actually keeps versus what is lost to refunds or chargebacks.
- Automated Order Cancellation: Bad orders are detected and cancelled instantly, saving merchants from costly and impossible-to-win chargebacks.
Blox provides Shopify merchants with the peace of mind that their store is protected not just from random attacks, but from persistent, targeted fraud attempts.
Availability
Blox: Chargeback Blacklist is available now for download on the Shopify App Store.
