# authorship

# setUncles(new_uncles: Vec<Header>)

  • interface: api.tx.authorship.setUncles

# balances

# forceTransfer(source: Address, dest: Address, value: Compact<Balance>)

# setBalance(who: Address, new_free: Compact<Balance>, new_reserved: Compact<Balance>)

  • interface: api.tx.balances.setBalance
  • summary: Set the balances of a given account. This will alter FreeBalance and ReservedBalance in storage. it will also decrease the total issuance of the system (TotalIssuance). If the new free or reserved balance is below the existential deposit, it will reset the account nonce (frame_system::AccountNonce). The dispatch origin for this call is root. # - Independent of the arguments. - Contains a limited number of reads and writes. #

# transfer(dest: Address, value: Compact<Balance>)

  • interface: api.tx.balances.transfer
  • summary: Transfer some liquid free balance to another account. transfer will set the FreeBalance of the sender and receiver. It will decrease the total issuance of the system by the TransferFee. If the sender's account is below the existential deposit as a result of the transfer, the account will be reaped. The dispatch origin for this call must be Signed by the transactor. # - Dependent on arguments but not critical, given proper implementations for input config types. See related functions below. - It contains a limited number of reads and writes internally and no complex computation. Related functions: - ensure_can_withdraw is always called internally but has a bounded complexity. - Transferring balances to accounts that did not exist before will cause T::OnNewAccount::on_new_account to be called. - Removing enough funds from an account will trigger T::DustRemoval::on_unbalanced and T::OnFreeBalanceZero::on_free_balance_zero. - transfer_keep_alive works the same way as transfer, but has an additional check that the transfer will not kill the origin account. #

# transferKeepAlive(dest: Address, value: Compact<Balance>)

  • interface: api.tx.balances.transferKeepAlive
