Federation | Stellar Documentation

The Stellar federation protocol maps Stellar addresses to an email-like identifier that provides more information about a given user. It’s a way for Stellar client software to resolve email-like addresses such as name*yourdomain.com into account IDs like: GCCVPYFOHY7ZB7557JKENAX62LUAPLMGIWNZJAFV2MITK6T32V37KEJU. Federated addresses provide an easy way for users to share payment details by using a syntax that interoperates across different domains and providers.

What do people think about incorporating a Stellar address that is unique to your federated account with your chosen insurance.

This would allow for people to send/receive stable coins such as circles USDC. I feel the stellar network would complement Lemmy or Mastodon quite well.
