FAQ

General Questions

Q: What is Self Name Resolution Snap? A: Self Name Resolution Snap is a MetaMask extension that allows users to resolve human-readable Self usernames into cryptocurrency addresses, supporting both .self and $: formats.

• BNB Smart Chain (EIP155:56)
• Avalanche (EIP155:43114)

Technical Questions

Q: Do I need a special version of MetaMask? A: Yes, you need MetaMask Flask installed to use this snap.

Q: How does the name resolution work? A: The snap communicates with the Self name resolution API to resolve usernames to their corresponding addresses on different chains. When you enter a Self username in MetaMask, the snap automatically queries the API and returns the appropriate address for the selected network.

Q: Can I resolve addresses back to username? A: No, currently the snap only supports forward resolution (usernames to addresses) and does not support reverse resolution.

Troubleshooting

Q: What should I do if name resolution fails? A: If name resolution fails:

1. Verify you're using a supported network
2. Check that the username is correctly formatted
3. Ensure you have a stable internet connection
4. Try refreshing MetaMask

Q: Why am I getting different addresses on different networks? A: This is expected behavior. Self usernames can resolve to different addresses on different blockchain networks, allowing users to have network-specific addresses under the same username.
