I think this kind of feature is on transak.com, a 3rd party provider that Metamask uses to buy and sell inside of their wallet.
It's not just Transak's feature but the government requirement (for 1st-time customers), the same goes for any other payment processor.
It says it is only for first-timer customers, is this your first time doing the transaction with Transak inside Metamask?
Yup, it was my first time on Transak and the first time I experienced that nonsense policy. I actually dropped the transaction and went to the exchange I was already registered with and deposited to the MetaMask. It was much quicker that way.
Indeed, it is ridiculous, like many regulations that reach the point of absurdity. (...)
The UK is increasingly treating its adult citizens as little kids, incapable of making decisions independently.
I think it's politicians/regulators desperately trying to prove that "they're doing something" instead of addressing real problems.
