Establish a bidirectional HRMP channel between a parachain and a system chain.
Establish an HRMP channel between two system chains. If the channel does not already
exist, the transaction fees will be refunded to the caller. The system does not take
deposits for channels between system chains, and automatically sets the message number
and size limits to the maximum allowed by the network’s configuration.
This extrinsic triggers the cleanup of all the HRMP storage items that a para may have.
Normally this happens once per session, but this allows you to trigger the cleanup
immediately for a specific parachain.
Open a channel from a sender
to a recipient
ParaId
. Although opened by governance,
the max_capacity
and max_message_size
are still subject to the Relay Chain’s
configured limits.
Force process HRMP close channel requests.
Force process HRMP open channel requests.
Accept a pending open channel request from the given sender.
This cancels a pending open channel request. It can be canceled by either of the sender
or the recipient for that request. The origin must be either of those.
Initiate unilateral closing of a channel. The origin must be either the sender or the
recipient in the channel being closed.
Initiate opening a channel from a parachain to a given recipient with given channel
parameters.
Update the deposits held for an HRMP channel to the latest Configuration
. Channels
with system chains do not require a deposit.
