Intro
The Require Auth setting prevents all counterparties from holding balances issued by an address unless the address has specifically approved an accounting relationship with that counterparty.
Video
Topics covered
- asfRequireAuth: Require authorization for users to hold balances issued by the issuer. Can only be enabled if the address has no trust lines connected to it.
- tfSetfAuth: Authorize the other party to hold currency issued by the issuer. (No effect unless issuer has asfRequireAuth AccountSet flag enabled.) tfSetfAuth once set by the issuer, can not be unset by the issuer.
- Deleting the TrustLine where the user account was authorized by the issuer using tfSetfAuth.
References
Final tip: Anybody can still set up a TrustLine with an issuer who has asfRequireAuth flag enabled, but can not hold the tokens issued by that issuer unless authorised by the issuer.
