Variants

OpenHrmpChannelToSelf

The sender tried to open a channel to themselves.

OpenHrmpChannelInvalidRecipient

The recipient is not a valid para.

OpenHrmpChannelZeroCapacity

The requested capacity is zero.

OpenHrmpChannelCapacityExceedsLimit

The requested capacity exceeds the global limit.

OpenHrmpChannelZeroMessageSize

The requested maximum message size is 0.

OpenHrmpChannelMessageSizeExceedsLimit

The open request requested the message size that exceeds the global limit.

OpenHrmpChannelAlreadyExists

The channel already exists

OpenHrmpChannelAlreadyRequested

There is already a request to open the same channel.

OpenHrmpChannelLimitExceeded

The sender already has the maximum number of allowed outbound channels.

AcceptHrmpChannelDoesntExist

The channel from the sender to the origin doesn’t exist.

AcceptHrmpChannelAlreadyConfirmed

The channel is already confirmed.

AcceptHrmpChannelLimitExceeded

The recipient already has the maximum number of allowed inbound channels.

CloseHrmpChannelUnauthorized

The origin tries to close a channel where it is neither the sender nor the recipient.

CloseHrmpChannelDoesntExist

The channel to be closed doesn’t exist.

CloseHrmpChannelAlreadyUnderway

The channel close request is already requested.

CancelHrmpOpenChannelUnauthorized

Canceling is requested by neither the sender nor recipient of the open channel request.

OpenHrmpChannelDoesntExist

The open request doesn’t exist.

OpenHrmpChannelAlreadyConfirmed

Cannot cancel an HRMP open channel request because it is already confirmed.

WrongWitness

The provided witness data is wrong.

ChannelCreationNotAuthorized

The channel between these two chains cannot be authorized.
