This is part of these companies' continuing efforts to move the financial industry on-chain. A prime example of this is Base, the Ethereum overlay blockchain attached to Coinbase which recently partnered with Shopify to offer global USDC payments.
“Our mission at Base is to build a global economy that increases innovation, creativity, and freedom. To do this, we need more founders to build on-chain businesses so that anyone, anywhere can participate in the global economy,” the blog post said.
The initiative comes as U.S. lawmakers move to clarify rules for crypto. The GENIUS Act, a new U.S. law governing stablecoins, aims to bring federal clarity by directing regulators to come up with specific rules for stablecoin issuers. U.S. lawmakers continue to work on broader crypto market structure legislation as well.
