The Special Return Mechanism (MED) is a tool created by the Central Bank of Brazil to help victims of fraud involving PIX. It's designed to increase security and help users recover their money after a scam, coercion, or unauthorized transaction.

We use MED when a user is the victim of:

  • Account invasion (unauthorized access or ATO)

  • Scams (fraud in online sales or misleading offers)

  • Coercion (forced transfers under threat)

  • Operational error (system mistake on our side)

When is a MED opened?

A MED is only opened after an initial review by our team. They’ll investigate your case, and determine if it qualifies for a MED request.

Types of MED

1. Invasion (Account Takeover)

This happens when a fraudster gains access to your AstroPay account and sends money via PIX without your consent.

Example:
Scammers create fake websites that promise a "deposit duplication bug."
They convince victims to share their screen, steal OTP codes, and access the account to withdraw funds.

Important: In these cases, a police report is required to open a MED.

2. Scam (Fraudulent Sales)

This applies when a product or service was paid via PIX but never delivered.

Common cases:

  • Online sales on Facebook or Instagram

  • The seller disappears after receiving the payment

To open a MED, we require:

  • Screenshots showing communication with the seller

  • Evidence that you tried to resolve the issue (e.g., asking for tracking info)

  • A police report

3. Coercion (Forced Transfers)

This happens when someone is forced to send PIX transfers under threat or violence.

Examples:

  • Kidnapping

  • Armed robbery

  • Blackmail

4. System Error (Internal Operational Failure)

If a technical issue in our system causes a duplicate or incorrect PIX transfer (not user error), we may open a MED to correct it.
