Calls

​
forceTransfer

Exactly as transfer, except the origin must be root and the source account may be specified. Namespace 
api.tx.balances.forceTransfer
Type 
function forceTransfer(
  source: SeedPrimitivesSignatureAccountId20,
  dest: SeedPrimitivesSignatureAccountId20,
  value: Compact<u128>
)

​
forceUnreserve

Unreserve some balance from a user by force. Can only be called by ROOT. Namespace 
api.tx.balances.forceUnreserve
Type 
function forceUnreserve(
  who: SeedPrimitivesSignatureAccountId20,
  amount: u128
)

​
setBalance

Set the balances of a given account. This will alter FreeBalance and ReservedBalance in storage. it will also alter the total issuance of the system (TotalIssuance) appropriately. 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. Namespace 
api.tx.balances.setBalance
Type 
function setBalance(
  who: SeedPrimitivesSignatureAccountId20,
  new_free: Compact<u128>,
  new_reserved: Compact<u128>
)

​
transfer

Transfer some liquid-free balance to another account. transfer will set the FreeBalance of the sender and receiver. 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. Namespace 
api.tx.balances.transfer
Type 
function transfer(
  dest: SeedPrimitivesSignatureAccountId20,
  value: Compact<u128>
)

​
transferAll

Transfer the entire transferable balance from the caller account. NOTE: This function only attempts to transfer transferable balances. This means that any locked, reserved, or existential deposits (when keep_alive is true), will not be transferred by this function. To ensure that this function results in a killed account, you might need to prepare the account by removing any reference counters, storage deposits, etc. The dispatch origin of this call must be Signed.
  • dest: The recipient of the transfer.
  • keep_alive: A boolean to determine if the transfer_all operation should send all of the funds the account has, causing the sender account to be killed (false), or transfer everything except at least the existential deposit, which will guarantee to keep the sender account alive (true). #
Namespace 
api.tx.balances.transferAll
Type 
function transferAll(
  dest: SeedPrimitivesSignatureAccountId20,
  keep_alive: bool
)

​
transferKeepAlive

Same as the transfer call, but with a check that the transfer will not kill the origin account. 99% of the time you want transfer instead. Namespace 
api.tx.balances.transferKeepAlive
Type 
function transferKeepAlive(
  dest: SeedPrimitivesSignatureAccountId20,
  value: Compact<u128>
)

​
Storage

​
account

The Balances pallet example of storing the balance of an account. Example nocompile impl pallet_balances::Config for Runtime { type AccountStore = StorageMapShim<Self::Account<Runtime>, frame_system::Provider<Runtime>, AccountId, Self::AccountData<Balance>> } You can also store the balance of an account in the System pallet. Example nocompile impl pallet_balances::Config for Runtime { type AccountStore = System } But this comes with tradeoffs, storing account balances in the system pallet stores frame_system data alongside the account data contrary to storing account balances in the Balances pallet, which uses a StorageMap to store balances data only. NOTE: This is only used in the case that this pallet is used to store balances. Namespace 
api.query.balances.account
Type 
function account(
  SeedPrimitivesSignatureAccountId20
): PalletBalancesAccountData
