Params:

  • null

Results:

  • String : DCAP

TotalSupply

func TotalSupply() TokenAmount {}

Return the total supply of DataCap token.

uint TotalSupplyMethodNum: 114981429.

Params:

  • null

Results:

  • int256 TokenAmount - Total DataCap token supply.

Balance

func Balance(params Address) TokenAmount {}

Return the DataCap token balance for the wallet address.

unit BalanceOfMethodNum: 3261979605.

Params:

  • bytes Address - the wallet address.

Results:

  • int256 TokenAmount - the DataCap token balance for the specified wallet address.

Transfer

func Transfer(params TransferParams) TransferReturn {}

Transfers DataCap tokens from caller address to the to address.

uint TransferMethodNum = 80475954;

Params:

  • struct TransferParams
    • bytes To - the address to receive DataCap token.
    • int256 Amount - A non-negative amount to transfer.
    • bytes[] OperatorData - Arbitrary data to pass on via the receiver hook.

Results:

  • struct TransferReturn
    • int256 FromBalance - the balance of from_address.
    • int256 ToBalance - the balance of to_address.
    • bytes RecipientData: data returned from receive hook.

TransferFrom

func TransferFrom(params TransferFromParams) TransferFromReturn {}

Transfers DataCap tokens between from the from_address to the to_address.

uint TransferFromMethodNum = 3621052141.

Params:
