Address syntax

matrix.org hosts a public instance of Bifröst for XMPP bridging. You can join any chat from either side of the bridge using the address syntax below. Change the parts in CAPS, everything else is literal (even the =40 in Matrix user ids).

Matrix -> XMPP

• Private chats: @_xmpp_USER=40DOMAIN:matrix.org
• MUCs: #xmpp_MUCNAME_MUCDOMAIN:matrix.org

XMPP -> Matrix

• Direct chats: USERNAME_DOMAIN@matrix.org
• Public chats: #ALIAS#DOMAIN@matrix.org

Important: As XMPP User you can only join rooms which address or local-alias-address is lower case.

Old syntax

The previous instance hosted by matrix.org, which died in April 2019, had a different syntax for XMPP -> Matrix addresses. They are here for historical reference only.

• Direct chats: USERNAME_DOMAIN@bridge.xmpp.matrix.org
• Public chats: #ALIAS#DOMAIN@bridge.xmpp.matrix.org
