        	            	      --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

        	            	      --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)
