Where can I see additional information on public federations?

Fedimint Observer is a helpful site that contains additional information on publicly known / observed federations.

The Home tab shows a list of all observed federations, along with their public ratings, invite codes, total assets, and average activity over the previous 7 days (number of transactions & total volume).

Clicking into a specific federation takes you to that federation's page, where you can see how many guardians it has & each guardian's status, the network it's running on, the number of confirmations required for on chain transactions, and more.

The Nostr tab displays other federations announced via Nostr and their invitation codes. Here, you can enter a federation invite code in the top bar to either check the federation's information or announce it. Feel free to try checking the information of one of the Nostr federations below.
