GetSmartContractSubState

---

Warning

This API is not yet implemented in this version of Zilliqa 2.0

Returns the state (or a part specified) of a smart contract address, represented in JSON format.

Note

The way that storage is encoded is different (and subject to change) between Scilla and EVM contracts. Whilst GetSmartContractSubState() may not fail if called on an address containing EVM code, it will not return meaningful results.

State Params

Parameter	Type	Required	Description
Address	string	Required	A smart contract address of 20 bytes.
Variable Name	string	Can be empty	Name of the variable in the Smart Contract
Indices	JSON Array	Can be empty	If the variable is of map type, you can specify an index (or indices)

The params is a JSON array.

Example: "params":["fe001824823b12b58708bf24edd94d8b5e1cfcf7","admins",[\"0x9bfec715a6bd658fcb62b0f8cc9bfa2ade71434a\""]]

Note

If Variable Name and Indices Array are both empty, the response will be the same as GetSmartContractState_
