Whitelisted Relayers

Sequencers are eligible to send gas-free IBC transactions to their RollApp. This enables efficient bootstrapping upon launch as well as post-launch operations.

By default, upon ibc connection initialization, roller registers the sequencer's relayer address to the whitelisted relayers list.

In case the sequencer whishes to registers more addresses (limited to 10), or update the existing relayer address, it first needs to obtain the relayer address he wants to whitelist.

From within the relayer machine (replace <rollapp-id> with the rollapp id):

/usr/local/bin/roller_bins/rly keys list <rollapp-id> --home ~/.roller/relayer/

After obtaining the relayer address, the sequencer can register it on Dymension L1 with the following command (where <relayer-addresses> is a comma-separated list of relayer addresses):

dymd tx sequencer update-whitelisted-relayers <relayer-addresses> --from [SEQUENCER_KEYS]
