USDC runs on Ethereum, which is a decentralized, programmable blockchain that allows developers to create a huge range of apps and tokens. … You can buy USDC via exchanges like Coinbase, and hold it in any Ethereum compatible wallet. There are no fees for transferring a US dollar to USDC
How did you get a balance there the 1st time? Or is it from a sale that you made and you kept the usdc in your wallet?
Maybe you dont have enough?
You have to have a crypto/coins wallet that has ETH (compatible with USDC) so you can either scan the QR code on Venly from the other crypto wallet and pay directly from there. Or transfer usdc to venly account.
