Revolut’s deposit instructions say to transfer USDC to it, you have to use a network called Polygon. In his first, successful, deposit Tzoni selected one called “Polygon PoS”.

In the second deposit, when he tried to transfer 1,500 USDC, he selected a different network - “Polygon (bridged)”.

He thought it would work just as well but says instead it caused the coins to be converted into USDC.e - a different cryptocurrency.

This is what Revolut received. The company does not handle USDC.e coins.

The article does not mention which wallet app or service Raykov transferred from. This is the more important factor I think. Whatever those USDC.e coins are, it sounds like the wallet “helpfully” traded the original tokens for different ones on another chain on his behalf and then sent those. While Revolut’s crypto offering is garbage and Revolut is a shady black company in general, it sounds like if anything the blame might be on the UX of his sending wallet being misleading and confusing.
