This section describes the configuration and commands that can be used to start the relayer and relay both handshake and packets for connections and channels.
To relay packets and handshake messages configure the
mode section of the configuration file like so:
[global] log_level = 'info' [mode] [mode.clients] enabled = true # ... [mode.connections] enabled = true [mode.channels] enabled = true [mode.packets] enabled = true # ...
Then start hermes using the start command:
The relayer sends handshake and packet transactions triggered by IBC events.
After the relayer is started using the
start command, it scans the chain state and will resume the handshake for any
channels or connections that are not in open state. It then listens to IBC events emitted by any of
the configured chains.
Assuming the events are coming from a
source chain, the relayer determines the
destination chain and builds the handshake messages based on these events. These are then sent to the
In addition to the events described in Packet Relaying, the following IBC events may be handled:
chan_open_init: the relayer builds a
chan_open_try: the relayer builds a
chan_open_ack: the relayer builds a
chan_open_confirm: no message is sent out, channel opening is finished
conn_open_init: the relayer builds a
conn_open_try: the relayer builds a
conn_open_ack: the relayer builds a
conn_open_confirm: no message is sent out, connection opening is finished
