🚧 Deprecation Notice

dfuse services will be discontinued on September 25, 2024, as Pinax transitions to more advanced and efficient solutions for Antelope blockchain data sourcing. We encourage all users to migrate to Pinax's new services, including Substreams, Firehose, and comprehensive blockchain data services supporting dozens of chains like EOS, WAX, and Telos. Dfuse users can start building with a FREE Pinax Pro Plan.

  Deposit to REX fund action. Deposits core tokens to user REX fund. All proceeds and expenses related to REX are added to or taken out of this fund. An inline transfer from 'owner' liquid balance is executed. All REX-related costs and proceeds are deducted from and added to 'owner' REX fund, with one exception being buying REX using staked tokens.

      "actions": 8
  }

  Buyrex action, buys REX in exchange for tokens taken out of user's REX fund by transferring core tokens from user REX fund and converts them to REX stake. By buying REX, user is lending tokens in order to be rented as CPU or NET resources.

  @pre A voting requirement must be satisfied before action can be executed. @pre User must vote for at least 21 producers or delegate vote to proxy before buying REX.

  @post User votes are updated following this action. @post Tokens used in purchase are added to user's voting power. @post Bought REX cannot be sold before 4 days counting from end of day of purchase.

• .sellrex

      "actions": 8
  }

  Sellrex action, sells REX in exchange for core tokens by converting REX stake back into core tokens at current exchange rate. If order cannot be processed, it gets queued until there is enough in REX pool to fill order, and will be processed within 30 days at most. If successful, user votes are updated, that is, proceeds are deducted from user's voting power. In case sell order is queued, storage change is billed to 'from' account.

• .rentcpu (DEPRECATED in favor of powerup)

  ```js { "price": 14207.327700136308, "loan_payment": 0, // tokens paid for the loan "loan_fund": 0, // Loan balance represents a reserve that is used at expiration for automatic loan renewal. "actions": 0 } ``` Rentcpu action, uses payment to rent as many SYS tokens as possible as determined by market price and stake them for CPU for the benefit of receiver, after 30 days the rented core delegation of CPU will expire. At expiration, if balance is greater than or equal to `loan_payment`, `loan_payment` is taken out of loan balance and used to renew the loan. Otherwise, the loan is closed and user is refunded any remaining balance.

• .rentnet (DEPRECATED in favor of powerup)

  {
      "price": 14207.327700136308,
      "loan_payment": 0, // tokens paid for the loan
      "loan_fund": 0, // Loan balance represents a reserve that is used at expiration for automatic loan renewal.
      "actions": 0
  }

  Rentnet action, uses payment to rent as many SYS tokens as possible as determined by market price and stake them for NET for the benefit of receiver, after 30 days the rented core delegation of NET will expire. At expiration, if balance is greater than or equal to loan_payment, loan_payment is taken out of loan balance and used to renew the loan. Otherwise, the loan is closed and user is refunded any remaining balance.

• .unstaketorex (uncommon user action)

      "actions": 0
  }

  Unstaketorex action, uses staked core tokens to buy REX.

  @pre A voting requirement must be satisfied before action can be executed. @pre User must vote for at least 21 producers or delegate vote to proxy before buying REX.

  @post User votes are updated following this action. @post Tokens used in purchase are added to user's voting power. @post Bought REX cannot be sold before 4 days counting from end of day of purchase.

• .mvtosavings (uncommon user action)

  {
      "rex": 98641.5893, // amount of REX to be moved.
      "actions": 1
  }

  Mvtosavings action, moves a specified amount of REX into savings bucket. REX savings bucket never matures. In order for it to be sold, it has to be moved explicitly out of that bucket. Then the moved amount will have the regular maturity period of 4 days starting from the end of the day.

• .mvfrsavings (uncommon user action)

  {
      "rex": 0, // amount of REX to be moved.
      "actions": 0

.cpu (CPU & NET as a resource)

.actions

• .delegatebw (DEPRECATED in favor of powerup)

  {
      "stake_net_quantity": 8.078099999999933, // tokens staked for NET bandwidth,
      "stake_cpu_quantity": 72.00140000000007, // tokens staked for CPU bandwidth,
      "actions": 321
  }

  Delegate bandwidth and/or cpu action. Stakes SYS from the balance of from for the benefit of receiver.

  @post All producers from account has voted for will have their votes updated immediately.

• .undelegatebw (DEPRECATED in favor of powerup)

  {
      "unstake_net_quantity": 1.05, // tokens to be unstaked from NET bandwidth
      "unstake_cpu_quantity": 11.3825, // tokens to be unstaked from CPU bandwidth
      "actions": 3
  }

  Undelegate bandwidth action, decreases the total tokens delegated by from to receiver and/or frees the memory associated with the delegation if there is nothing left to delegate.

  This will cause an immediate reduction in net/cpu bandwidth of the receiver.

  A transaction is scheduled to send the tokens back to from after the staking period has passed. If existing transaction is scheduled, it will be canceled and a new transaction issued that has the combined undelegated amount.

  The from account loses voting power as a result of this call and all producer tallies are updated.

  @post Unstaked tokens are transferred to from liquid balance via a deferred transaction with a delay of 3 days. @post If called during the delay period of a previous undelegatebw action, pending action is canceled and timer is reset. @post All producers from account has voted for will have their votes updated immediately. @post Bandwidth and storage for the deferred transaction are billed to from.
