Welcome! If youre looking to create your own crypto payment system, Ive got a blog post thats worth reading. Im based in the UK and was helping a friend explore payment options for his online store. We Googled around and landed on https://merehead.com/blog/create-crypto-payment-gateway/ and honestly, it gave us a clear direction. It doesn't try to sell you stuff, just walks you through the essentials in a very logical flow. Definitely helped us get things moving.
