#UPDATE-BITSHARES-How to creating a new UIA [ASSET] Manually

 CREATING AN ASSET

Of course a UIA can also be created manually by means of the CLI Wallet command: 

>>> create_asset <issuer> <symbol> <precision> <options> {} false

 Note : A false at the end allows to check and verify the constructed transaction and does not broadcast it. The empty {} could be used to construct a Market Pegged Assets and is subject of another tutorial. 

 PARAMETERS

The precision can any positive integer starting from 0. As options we pass a JSON object that can contain these settings: 

{

   "max_supply" : 10000,    # Integer in satoshi! (100 for precision 1 and max 10)

   "market_fee_percent" : 0.3,

   "max_market_fee" : 1000, # in satoshi

   "issuer_permissions" : <permissions>,

   "flags" : <flags>,

   "core_exchange_rate" : {

       "base": {

         "amount": 21,           # denominator

         "asset_id": "1.3.0"     # BTS

       },

       "quote": {

         "amount": 76399,        # numerator

         "asset_id": "1.3.1"     # !THIS! asset

       }

   },

   "whitelist_authorities" : [],

   "blacklist_authorities" : [],

   "whitelist_markets" : [],

   "blacklist_markets" : [],

   "description" : "My fancy description"

}

The flags are construction as an JSON object containing these flags/permissions (see Assets FAQ):

{

   "charge_market_fee" : true,

   "white_list" : true,

   "override_authority" : true,

   "transfer_restricted" : true,

   "disable_force_settle" : true,

   "global_settle" : true,

   "disable_confidential" : true,

   "witness_fed_asset" : true,

   "committee_fed_asset" : true

}

Permissions and flags are modelled as sum of binary flags (see example below)White-listing is described in more detail in Asset User Whitelists. 

 ISSUING SHARES

After creation of the asset, no shares will be in existence until they are issued by the issuer:

issue_asset <account> <amount> <symbol> <memo> True
