Which payment app has wallet without KYC?

I'm curious, which payment application out there currently offers a wallet feature that doesn't require Know Your Customer (KYC) verification? In the realm of cryptocurrency and finance, privacy and anonymity are often sought-after features, especially by those looking to transact without leaving a traceable digital footprint. So, is there a specific app that caters to this demand, allowing users to securely store and manage their digital assets without having to undergo the KYC process? If so, what are the advantages and potential risks associated with using such a service?
