This worker has finally achieved "on-chain salary freedom"—depositing USDC into the Solayer Emerald Card, earning 4% interest daily (backed by US Treasury bonds, much better than Yu'ebao), and can also be used directly as a Visa card! Last week when I bought Starbucks, the clerk looked at me like I was an alien when I paid with the crypto card. The most impressive feature is the sub-account function: I opened a family card for my mom with a monthly limit of 500U, and she no longer has to ask me how to transfer USDC. However, small fund players should be cautious, as on-chain operations occasionally incur gas fees that could buy two cups of milk tea. Has anyone used the Emerald Card to get even better deals? Please share hidden benefits! @Solayer #BuiltonSolayer $LAYER
