I dont think we will see it for a while. In the mean time stop using 0x addresses on Ethereum. Thanks to the innovations developed by ECC/Zcash we now have Railgun on Ethereum, get yourself an 0zk address. You can privately interact with DeFi on ETH as in swap and use any ERC-20 token PRIVATELY. Cutting edge stuff, all thanks to ZEC.
