Calling Contract Functions

Read data and make transactions on your contract from the connected wallet.

Read Contract Data

Use the name of the function, view, or mapping, and provide any required arguments.

React

const { contract } = useContract("{{contract_address}}");
const { data: myData, isLoading } = useContractRead(contract, "myFunction");

JavaScript

// read functions will return the data from the contract
const myValue = await contract.call("myReadFunction");
console.log(myValue);

Unity

// Place the type of the return value in the <> brackets
var result = await contract.Read<string>("functionName", arg1, arg2);

Write Transactions

Transactions are made using the connected wallet (or the wallet you instantiated the SDK with).

React

const { contract } = useContract("{{contract_address}}");
const { mutateAsync: myFunctionAsync } = useContractWrite(contract, "myFunction");
const tx = await myFunctionAsync(["argument1", "argument2"]) // Call the function

JavaScript

// write functions will return the transaction receipt
const tx = await contract.call("myWriteFunction", arg1, arg2);
const receipt = tx.receipt;
// Optionally override transaction options
await contract.call("myWriteFunction", arg1, arg2, {
  gasLimit: 1000000, // override default gas limit
  value: ethers.utils.parseEther("0.1"), // send 0.1 ether with the contract call
});

Unity

await contract.Write("functionName", arg1, arg2);
