Could we please get more docs on (SetUserName or/and register endpoint for DNS smart contracts)?
Mainly:
- How to calculate DNS smart contract address for SetUserName/register
- Why is there a difference between the mainnet smart contracts and devnet/testnet ones (the same operation throws "Not a DNS address" on the devnet but works ok on the mainnet?)
- How long will the .elrond suffix be supported? What will be the new one .mvx? Will both work at the same time?
- What will be the migration steps
Thank you.
