Layer 1 blockchains are predicted to be the primary beneficiaries of the stablecoin act, as the entire financial system (payments, lending, borrowing) moves onto them.
"The biggest winners of all of this of course are going to be the L1's because the L1's where most of the financial system gets moved to are the ones that are greatly going to that are most greatly going to benefit. Starting off with basic stable coin transactions, but actually moving to so the first act the first part of the stable coin thing is just going to be payments. I pay you, you pay me. The second part of it is that we're going to move the financial system onto the L1's. So you're going to move lending, you're going to move borrowing, you're going to move all that stuff onto the L1's."
