MathWallet5 has supported DAS(.bit) names
Here is how to use these names in MathWallet5
When you open the transfer UI, enter the target domain name in the address field, and MathWallet will resolve that name.
You will see which name system it is, and click the name system button to double check the target address
Note that some of the name system supports multi-chain, and MathWallet will resolve based on the current blockchain.
If you’d like to get your own .bit name, you can open mathdapp.store, search ‘DAS’ and start the bid process for you name selection.
