Smart contract functions
Helps to retrieve information from the blockchain smart contract.
MBFUNCTIONLIST(contract, filter)
Retrieve a detailed list of a smart contract's functions.
Parameters
-
contractSmart contract label, must be associated with the address. -
filter(Optional) Regular expression (regex) to filter function names on.
Return
Array of smart contract functions and their inputs and outputs.
Example
=MBFUNCTIONLIST("erc20interface") in the cell. The structure of the return value is as follows:
| function | description | read/write | inputs | outputs |
|---|---|---|---|---|
| allowance | read | "2 inputs: tokenOwner address spender address" | "1 output: remaining uint256" | |
| approve | write | "2 inputs: spender address tokens uint256" | "1 output: success bool" | |
| balanceOf | read | "1 input: tokenOwner address" | "1 output: balance uint256" | |
| decimals | read | no inputs | "1 output: uint8" | |
| name | read | no inputs | "1 output: string" | |
| symbol | read | no inputs | "1 output: string" | |
| totalSupply | read | no inputs | "1 output: uint256" | |
| transfer | write | "2 inputs: to address | tokens uint256" | |
| transferFrom | write | "3 inputs: from address to address tokens uint256" | "1 output: success bool" |
MBGET(address, contract, method, ...args)
Retrieve the results of a smart contract function call.
Parameters
-
addressEthereum address or label. -
contractSmart contract label, must be associated with the address. -
methodSmart contract function name. -
args(Optional) Arguments to pass to the function.
Return
One or more values returned from the function.
Example
=MBGET("privatefaucet", "multibaasfaucet", "getOperator") in the cell. The structure of the return value is as follows:
