        --height-offset <HEIGHT_OFFSET>

        --host-chain <HOST_CHAIN_ID>
            Identifier of the host chain

        --host-client <HOST_CLIENT_ID>
            Identifier of the client on the host chain from which the plan is created

Example

An upgrade proposal is made for ibc-0, for height 300 blocks from the latest height, with 10000000stake deposited. The proposal will include the upgraded client state constructed from the state of 07-tendermint-0 client on ibc-1.

If the chain is using ibc-go version v8.0.0 or higher, the authority account for the governance module needs to be used. To query the account use:

<CHAIN_BINARY> query auth module-account gov

or

<CHAIN_BINARY> query auth module-accounts

And then

hermes tx upgrade-chain --gov-account <QUERIED_ACCOUNT> --reference-chain ibc-0 --host-chain ibc-1 --host-client 07-tendermint-0 --amount 10000000 --height-offset 60

If the ibc-go version used is lower than v8.0.0 you can ignore the --gov-account flag as it will not be used.

hermes tx upgrade-chain --reference-chain ibc-0 --host-chain ibc-1 --host-client 07-tendermint-0 --amount 10000000 --height-offset 60
