Submit an IBC upgrade proposal
# Synopsis
Submit an IBC client breaking upgrade proposal along with an initial deposit. The client state specified is the upgraded client state representing the upgraded chain Example Upgraded Client State JSON: { "@type":"/ibc.lightclients.tendermint.v1.ClientState", "chain_id":"testchain1", "unbonding_period":"1814400s", "latest_height":{"revision_number":"0","revision_height":"2"}, "proof_specs":[{"leaf_spec":{"hash":"SHA256","prehash_key":"NO_HASH","prehash_value":"SHA256","length":"VAR_PROTO","prefix":"AA=="},"inner_spec":{"child_order":[0,1],"child_size":33,"min_prefix_length":4,"max_prefix_length":12,"empty_child":null,"hash":"SHA256"},"max_depth":0,"min_depth":0},{"leaf_spec":{"hash":"SHA256","prehash_key":"NO_HASH","prehash_value":"SHA256","length":"VAR_PROTO","prefix":"AA=="},"inner_spec":{"child_order":[0,1],"child_size":32,"min_prefix_length":1,"max_prefix_length":1,"empty_child":null,"hash":"SHA256"},"max_depth":0,"min_depth":0}], "upgrade_path":["upgrade","upgradedIBCState"], }

# Options
-a, --account-number uint The account number of the signing account (offline mode only)
--aux Generate aux signer data instead of sending a tx
-b, --broadcast-mode string Transaction broadcasting mode (sync|async) (default "sync")
--chain-id string The network chain ID
--deposit string deposit of proposal
--description string description of proposal
--dry-run ignore the --gas flag and perform a simulation of a transaction, but don't broadcast it (when enabled, the local Keybase is not accessible)
--fee-granter string Fee granter grants fees for the transaction
--fee-payer string Fee payer pays fees for the transaction instead of deducting from the signer
--fees string Fees to pay along with transaction; eg: 10uatom
--from string Name or address of private key with which to sign
--gas string gas limit to set per-transaction; set to "auto" to calculate sufficient gas automatically. Note: "auto" option doesn't always report accurate results. Set a valid coin value to adjust the result. Can be used instead of "fees". (default 200000)
--gas-adjustment float adjustment factor to be multiplied against the estimate returned by the tx simulation; if the gas limit is set manually this flag is ignored (default 1)
--gas-prices string Gas prices in decimal format to determine the transaction fee (e.g. 0.1uatom)
--generate-only Build an unsigned transaction and write it to STDOUT (when enabled, the local Keybase only accessed when providing a key name)
-h, --help help for ibc-upgrade
--keyring-backend string Select keyring's backend (os|file|kwallet|pass|test|memory) (default "os")
--keyring-dir string The client Keyring directory; if omitted, the default 'home' directory will be used
--ledger Use a connected Ledger device
--node string <host>:<port> to tendermint rpc interface for this chain (default "tcp://localhost:26657")
--note string Note to add a description to the transaction (previously --memo)
--offline Offline mode (does not allow any online functionality)
-o, --output string Output format (text|json) (default "json")
-s, --sequence uint The sequence number of the signing account (offline mode only)
--sign-mode string Choose sign mode (direct|amino-json|direct-aux), this is an advanced feature
--timeout-height uint Set a block timeout height to prevent the tx from being committed past a certain height
--tip string Tip is the amount that is going to be transferred to the fee payer on the target chain. This flag is only valid when used with --aux, and is ignored if the target chain didn't enable the TipDecorator
--title string title of proposal
-y, --yes Skip tx broadcasting prompt confirmation
