  31. --, --longhelp Print help message for long options (common options)
  32. -a, --tx-fee-adj= f Adjust transaction fee by factor 'f' (see below)
  33. -b, --brain-params=l,p Use seed length 'l' and hash preset 'p' for
  34. brainwallet input
  35. -B, --no-blank Don't blank screen before displaying unspent outputs
  36. -c, --comment-file= f Source the transaction's comment from file 'f'
  37. -C, --tx-confs= c Desired number of confirmations (default: {g.tx_confs})
  38. -d, --outdir= d Specify an alternate directory 'd' for output
  39. -D, --contract-data= D Path to hex-encoded contract data (ETH only)
  40. -e, --echo-passphrase Print passphrase to screen when typing it
  41. -E, --fee-estimate-mode=M Specify the network fee estimate mode. Choices:
  42. {fe[1]}. Default: '{fe[1][0]}'
  43. -f, --tx-fee= f Transaction fee, as a decimal {cu} amount or as
  44. {fu} (an integer followed by {fl}).
  45. See FEE SPECIFICATION below. If omitted, fee will be
  46. calculated using network fee estimation.
  47. -g, --tx-gas= g Specify start gas amount in Wei (ETH only)
  48. -H, --hidden-incog-input-params=f,o Read hidden incognito data from file
  49. 'f' at offset 'o' (comma-separated)
  50. -i, --in-fmt= f Input is from wallet format 'f' (see FMT CODES below)
  51. -I, --inputs= i Specify transaction inputs (comma-separated list of
  52. MMGen IDs or coin addresses). Note that ALL unspent
  53. outputs associated with each address will be included.
  54. -l, --seed-len= l Specify wallet seed length of 'l' bits. This option
  55. is required only for brainwallet and incognito inputs
  56. with non-standard (< {g.seed_len}-bit) seed lengths.
  57. -k, --keys-from-file=f Provide additional keys for non-{pnm} addresses
  58. -K, --key-generator= m Use method 'm' for public key generation
  59. Options: {kgs}
  60. (default: {kg})
  61. -L, --locktime= t Lock time (block height or unix seconds) (default: 0)
  62. -m, --minconf=n Minimum number of confirmations required to spend
  63. outputs (default: 1)
  64. -M, --mmgen-keys-from-file=f Provide keys for {pnm} addresses in a key-
  65. address file (output of '{pnl}-keygen'). Permits
  66. online signing without an {pnm} seed source. The
  67. key-address file is also used to verify {pnm}-to-{cu}
  68. mappings, so the user should record its checksum.
  69. -O, --old-incog-fmt Specify old-format incognito input
  70. -p, --hash-preset= p Use the scrypt hash parameters defined by preset 'p'
  71. for password hashing (default: '{g.hash_preset}')
  72. -P, --passwd-file= f Get {pnm} wallet passphrase from file 'f'
  73. -r, --rbf Make transaction BIP 125 (replace-by-fee) replaceable
  74. -q, --quiet Suppress warnings; overwrite files without prompting
  75. -u, --subseeds= n The number of subseed pairs to scan for (default: {ss},
  76. maximum: {ss_max}). Only the default or first supplied
  77. wallet is scanned for subseeds.
  78. -v, --verbose Produce more verbose output
  79. -V, --vsize-adj= f Adjust transaction's estimated vsize by factor 'f'
  80. -X, --cached-balances Use cached balances (Ethereum only)
  81. -y, --yes Answer 'yes' to prompts, suppress non-essential output
  82. -z, --show-hash-presets Show information on available hash presets
