Wallet API - Calls¶
The wallet (cli_wallet
) requires a running full node to connect to because
it does not offer P2P or blockchain capabilities directly.
If you have not set up your wallet yet, you can find more information on the Wallet-CLI Tutorial and the CLI Wallet - FAQ pages.

An asset which enforces a whitelist specifies a list of accounts to maintain its whitelist, and a list of accounts to maintain its blacklist. In order for a given account A to hold and transact in a whitelisted asset S, A must be whitelisted by at least one of S’s whitelist_authorities and blacklisted by none of S’s blacklist_authorities.

(const string &publishing_account, const string &symbol_or_id, const price_feed &feed, bool broadcast = false) const Publishes a price feed for the named asset.
Price feed providers use this command to publish their price feeds for market-issued assets. A price feed is used to tune the market for a particular market-issued asset. For each value in the feed, the median across all committee_member feeds for that asset is calculated and the market for the asset is configured with the median of that value.
The feed object in this command contains three prices: a call price limit, a short price limit, and a settlement price. The call limit price is structured as (collateral asset) / (debt asset) and the short limit price is structured as (asset for sale) / (collateral asset). Note that the asset IDs are opposite to eachother, so if we’re publishing a feed for USD, the call limit price will be CORE/USD and the short limit price will be USD/CORE. The settlement price may be flipped either direction, as long as it is a ratio between the market-issued asset and its collateral.
- Return
the signed transaction updating the price feed for the given asset
- Parameters
publishing_account
: the account publishing the price feedsymbol_or_id
: the symbol or id of the asset whose feed we’re publishingfeed
: the price_feed object containing the three prices making up the feedbroadcast
