What is the Primary Name?
Your Primary Name tells apps which ENS name to display when they look up your wallet address. The Primary Name resolurion comprises two lookups, in two directions:
Forward Resolution
Forward resolution describes where your name points to and is determined by the ETH Address record set on your ENS name.
Reverse Resolution
Reverse resolution describes where your wallet points to and is determined by the Primary Name record set in your wallet.
For the Primary Name to work:
Both records must be set: your name pointing to your address, and your address pointing to your name.
