How to get the second element of the array in a smart contract (params)?

Moralis General

Hello.

Docs:

params (optional): Parameters needed for your specific function

Contract:

address[] public users;

How to get user ID 1?

params: [1],

or

params: {args: [1]},

Please tell me, since this is not in the documentation. Or I overlooked.

				"name": "",

How to get second element of array using react-moralis useApiContract?

array = function, but the parameters are unnamed

params - object, and requires specifying the name of the parameter

#7

you can change the abi and give those parameters a name, that requires no change at contract level
