When you check DAI on coinbase and chainlist.org , you will find DAI on coinbase , but you can find it on chainlist.org .
There is only xDAI on chainlist.org . What’s difference between DAI and xDAI ?
DAI is ERC20 Token on Ethereum Blockchain ,
xDAI has it’s own Chain. That’s why you can find xDAI on chainlist.org but you can not find DAI there .
And old DAI now is SAI.
