It is important for any investor to acknowledge the Coinbase effect within blockchain. Coinbase listing provides liquidity for individuals, specifically in the United States, who have limited access to exchange options. Rosetta is an API (a verification protocol that executes requests between two or more systems, think of a waiter being the API link between the table they're serving and the chefs who obtain the message of the order). Coins, to be listed on Coinbase, are required to have a Rosetta integration within it. As of January, the Rosetta API integration within the ICON protocol has been complete and you can find it on their github repository!
