# und tx gov submit-legacy-proposal param-change
Submit a parameter change proposal
# Synopsis
Submit a parameter proposal along with an initial deposit. The proposal details must be supplied via a JSON file. For values that contains objects, only non-empty fields will be updated.
IMPORTANT: Currently parameter changes are evaluated but not validated, so it is very important that any "value" change is valid (ie. correct type and within bounds) for its respective parameter, eg. "MaxValidators" should be an integer and not a decimal.
Proper vetting of a parameter change proposal should prevent this from happening (no deposits should occur during the governance process), but it should be noted regardless.
Example: $ und tx gov submit-proposal param-change <path/to/proposal.json> --from=<key_or_address>
Where proposal.json contains:
{ "title": "Staking Param Change", "description": "Update max validators", "changes": [ { "subspace": "staking", "key": "MaxValidators", "value": 105 } ], "deposit": "1000stake" }
und tx gov submit-legacy-proposal param-change [proposal-file] [flags]
# 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
--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 param-change
--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
-y, --yes Skip tx broadcasting prompt confirmation
