validate

▸ validate(type, method, args?): void

Validate arguments passed to the method as corresponding to the ones in the abi

Parameters

Name	Type	Default value	Description
type	"CALL" | "DEPLOY" | "INVOKE"	undefined	ValidateType - type of the method
method	string	undefined	string - name of the method

---

compile

▸ compile(method, argsCalldata): Calldata

Compile contract callData with abi Parse the calldata by using input fields from the abi for that method

Parameters

Name	Type	Description
method	string	string - method name
argsCalldata	RawArgs	RawArgs - arguments passed to the method. Can be an array of arguments (in the order of abi definition), or an object constructed in conformity with abi (in this case, the parameter can be in a wrong order).

Returns

Calldata

Calldata - parsed arguments in format that contract is expecting

Example

const calldata = myCallData.compile("constructor", ["0x34a", [1, 3n]]);

const calldata2 = myCallData.compile("constructor", {list:[1, 3n], balance:"0x34"}); // wrong order is valid

response	string[]	string[] - response from the method

Returns

Result

Result - parsed response corresponding to the abi

Defined in

response	string[]	string[] - serialized data corresponding to typeCairo.

Returns

AllowArray<Result>

Result or Result[] - parsed response corresponding to typeData.

Example

const res2=helloCallData.decodeParameters("hello::hello::UserData",["0x123456","0x1"]);
result = { address: 1193046n, is_claimed: true }
