Support posts and feed items

Support feed items can show public supporter messages and purchase context when the buyer chooses to post or share. A buyer can also choose to make a shop purchase or commission public without writing a message.

Every support item Supper publishes is checked against ATM's payment proof. Choosing public also creates a matching public payment record: on a signed-in supporter's atmosphere account, or as an anonymous ATM-owned record for a guest. Choosing private creates neither a public support item nor a payer record.

For support items published to a signed-in supporter's atmosphere account, compatible apps can independently follow the payer-record reference and check the active payment proof with a trusted broker. Guest support items remain Supper-hosted, but Supper's public feed includes the exact anonymous ATM payment-record and broker-proof references so compatible clients can perform the same check. The verified marker is Supper's current result; independent clients should resolve the references themselves.

Supper can also show related Bluesky or compatible social posts, replies, and original-post links when a supporter or creator shares support publicly. Those social posts are governed by the service where they were posted, such as Bluesky, even when Supper displays them as part of a support feed.
