The harshest comment I have seen about this news is: Damn it, the world's most successful fintech company Stripe actually chose not to build Rollup layer 2 on Ethereum, but to build its own independent chain. This is not "ultrasonic cash" at all, it's too much of a "digital oil" face. But think about the benefits. At least based on the current information, this independent payment chain is EVM compatible and uses Solidity language. All EVM chains can be considered positive for Ethereum, right??
