My experience using this, I picked "Frame" from their list of clients.

1. Getting USDC from the faucet was pretty easy 2. Connecting Frame to my browser worked well, x402 was immediately detected 3. The first transaction got lost, I submitted it and the page spun forever. I had to make a second transaction to make it work. If this was real money, it'd be super easy to make people pay twice, because my first transaction is probably languishing in a mempool somewhere. 4. Frame is a terrible tool to suggest. It has no transaction log, so once you commit you can't use any of the tricks like "send another transaction with the same nonce, but with more gas" in case it got lost. It also appears to be largely unmaintained. 5. Second transaction worked fine, processing was nearly instant, the feedback was good.
