## Behavior

- Reserved addresses come from two sources: chain-derived path addresses (cosmos coin wrapper paths and backed paths) that are flagged automatically when a collection adds them, and addresses set by governance through [MsgSetReservedProtocolAddress](https://docs.bitbadges.io/token-standard/messages/msg-set-reserved-protocol-address).
- Approval criteria address checks can match or exclude reserved protocol addresses. See [Special Address Flags](https://docs.bitbadges.io/token-standard/approval-criteria/special-address-flags).
