Axelar validators exchange messages with one another via the Axelar blockchain. Each validator sends these messages from a separate broadcaster account.

⚠️

Caution: A validator can only register one broadcaster address throughout its lifetime. This broadcaster address cannot be changed after it has been registered. If you need to register a different proxy address then you must also create an entirely new validator.

Learn your broadcaster account address

$AXELARD_HOME/bin/axelard keys show broadcaster -a --home $AXELARD_HOME

Let {BROADCASTER_ADDR} denote your broadcaster address
