We are pleased to offer you the first POS app that works with the new USDC stablecoin! This app is called Dappos and can be accessed by clicking on the icon below. In the future we plan to add new functionality such as invoicing and reporting. Contact us with your feature requests.
After you launch the app click on the logo on the upper left and create an account with your email address. Then under settings you can insert your Ethereum wallet address where you will receive payments. NOTE: there is a unique wallet address in your Coinbase account. Be sure to use this address or your payments may be lost. To accept the USDC stablecoin you will need to click on the link to “Add new ERC-20” token, label it “USDC,” select the number of decimals as “6” and insert the USDC contract address: “0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48”. We recommend setting the number of confirmations to 1. Also turn off the “fiat conversion” because 1 USDC will always be equal to 1 US dollar.
Please note that for the app to work correctly on some computers you must install and turn on Metamask in your browser. This is also a wallet, but you do not need to have any funds in it. We hope to eliminate this requirement in a future release.
After a customer scans the Dappos QR code and sends their payments it can take several minutes for the transaction to appear on the network. When Dappos detects the transaction it will begin “looking” for a confirmation. You can also check the status of your transaction on Etherscan. Simply insert your sending or receiving address in the box at the upper right side of the page. At this time the Coinbase App wallet works with Dappos. Some other wallets may not recognize the Dappos QR code.
