  48. e- -D, --contract-data= D Path to file containing hex-encoded contract data
  49. -- -e, --echo-passphrase Print passphrase to screen when typing it
  50. b- -E, --fee-estimate-mode=M Specify the network fee estimate mode. Choices:
  51. + {fe_all}. Default: {fe_dfl!r}
  52. -- -f, --fee= f Transaction fee, as a decimal {cu} amount or as
  53. + {fu} (an integer followed by {fl!r}).
  54. + See FEE SPECIFICATION below. If omitted, fee will be
  55. + calculated using network fee estimation.

  58. + 'f' at offset 'o' (comma-separated)
  59. -- -i, --in-fmt= f Input is from wallet format 'f' (see FMT CODES below)
  60. -- -I, --inputs= i Specify transaction inputs (comma-separated list of
  61. + MMGen IDs or coin addresses). Note that ALL unspent
  62. + outputs associated with each address will be included.
  63. -- -l, --seed-len= l Specify wallet seed length of 'l' bits. This option
  64. + is required only for brainwallet and incognito inputs
  65. + with non-standard (< {dsl}-bit) seed lengths.
  66. -- -k, --keys-from-file=f Provide additional keys for non-{pnm} addresses
  67. -- -K, --keygen-backend=n Use backend 'n' for public key generation. Options
  68. + for {coin_id}: {kgs}
  69. bt -l, --locktime= t Lock time (block height or unix seconds) (default: 0)

  74. + address file (output of '{pnl}-keygen'). Permits
  75. + online signing without an {pnm} seed source. The
  76. + key-address file is also used to verify {pnm}-to-{cu}
  77. + mappings, so the user should record its checksum.
  78. -- -O, --old-incog-fmt Specify old-format incognito input
  79. -- -p, --hash-preset= p Use the scrypt hash parameters defined by preset 'p'
  80. + for password hashing (default: '{gc.dfl_hash_preset}')
