Just got coinbase wallet. All coins in there have identical ERC20 addresses.

Except for a few like Doge and maybe another coin or two, they all have identical addresses.

I wanted to transfer my 70 ZIL to it from atomic wallet, but I couldn't because it said address was invalid. That's when I realized it was an ETH address and checked the other coins. They all have the same address.

Can someone let me know what's going on here? That's not supposed to happen… 😆
