Changes in HF24/Eclipse RPC nodes:

Almost everything is rebranded in this version. You have to update anything that includes the word "steem" or "sbd" in your apps.

All the listed changes will only take effect on the eclipse RPC nodes. It means you must not apply the updates in the production until there is a final release candidate.
Also, the old public nodes will continue running to give you enough time for updating your applications.
In the meantime, @gtg maintains an early version which you can test your apps with (It is the mainnet)

Affected operations:

  • comment_options (!)
    Old: percent_steem_dollars
    New: percent_hbd

  • escrow_transfer
    Old: steem_amount, sbd_amount
    New: hive_amount, hbd_amount

  • escrow_release
    Old: steem_amount, sbd_amount
    New: hive_amount, hbd_amount

  • claim_reward_balance
    Old: reward_steem, reward_sbd
    New: reward_hive, reward_hbd

  • author_reward (virtual operation)
    Old: steem_payout, sbd_payout
    New: hive_payout, hbd_payout

  • witness_update
    Old: sbd_interest_rate
    New: hbd_interest_rate

  • witness_set_properties
    Old: sbd_interest_rate, sbd_exchange_rate
    New: hbd_interest_rate, hbd_exchange_rate

Affected API calls:
Replace all the steem with hive and all the sbd with hbd in the received JSON object.
There is one exception in percent_steem_dollars which is now percent_hbd!

  • condenser_api.get_accounts (and other similar calls returning an account object like condenser_api.lookup_account_names)
  • condenser_api.get_blog
  • condenser_api.get_chain_properties
  • condenser_api.get_content
  • condenser_api.get_content_replies
  • condenser_api.get_discussions_by_*
  • condenser_api.get_dynamic_global_properties
  • condenser_api.get_market_history
  • condenser_api.get_ticker
  • condenser_api.get_version
  • condenser_api.get_volume
  • condenser_api.get_witness_by_account
  • condenser_api.get_witness_schedule
  • bridge.get_ranked_posts
  • All database_api equivelants of the methods above
  • database_api.list_escrows
  • database_api.find_sbd_conversion_requests (method renamed)
  • database_api.list_sbd_conversion_requests (method renamed)
  • database_api.find_witnesses
  • market_history_api.get_market_history
  • market_history_api.get_order_book
  • market_history_api.get_ticker
  • market_history_api.get_volume
  • tags_api.get_discussion
  • tags_api.get_discussions_by_*

Updated libraries:

Hive-js (see v0.8.2)

In order to connect to the eclipse RPC nodes, you have to set rebranded_api in the config.json to true.


hive.config.set('rebranded_api', true)

There is also a helper function to get the node version and update the config:

hive.utils.autoDetectApiVersion().then(() => {

Note: Calling hive.broadcast.updateOperations() is necessary after updating the rebranded_api.

Dhive (see MR16 - v0.14.1)

In order to connect to the eclipse RPC nodes, the easy way is:

const client = new dhive.Client("https://rpc", { rebrandedApi: true })


client.updateOperations(true) // true: hf24

And with the helper function:

const client = new dhive.Client("https://rpc")
client.database.getVersion().then((res) => {
  if (res.blockchain_version !== '0.23.0') {

Hive-tx (see v3.1.8)

hiveTx.config.rebranded_api = true

OR'condenser_api.get_version').then(res => {
  if (res.result.blockchain_version !== '0.23.0') {
    hiveTx.config.rebranded_api = true

Beem is also updated:

For the other libraries visit their repository for more information.

Note: the chain id is also changed in the HF24. But you don't have to worry about it since the libraries will take care of that.
