poolimint - nostr is the accounts? Then ecash can only be “unlocked” with nsec. Maybe a proxy in front of the fedimint for actual pool software? Pool software gets main coinbase address from the fedimint. Shares are submitted as usual, and tallied up. Reward total is passed in from the pool to the fedimint so the respective npubs have their share according to pool rules. Ecash redemptions can be made by verifying ownership of said npub.
