If you’re willing to setup a business for this, there are services that provide registered office addresses at different locations, basically a mailbox for registration purpose.

For conveniency pick a city relatively close, but not necessarily your city of residence. Lookup services in your country to get details and prices.

It’ll have a cost, and it won’t make it perfectly anonymous, company records probably will show your name, and the registration/hosting service know who you are.

It really depends who you want to prevent from having your identity. It’s likely impossible to receive money while being perfectly anonymous from all involved parties.
