When signing up for GamerPay, you are not required to complete the KYC/verification process, and you are free to use the platform to both buy and sell skins without doing so ✅

If you receive cash from the sale of a skin (or in any other way), you must complete the KYC/verification process in order to use your wallet to purchase other skins or withdraw funds to your bank account. If you have not completed the ID validation, you will be asked to do so 🏦
​

If you are verified, but still face issues with paying with your wallet, it might be that your account is in review or that your Steam account is private.
