useSendTransaction

Hook to send one or several transaction(s) to the network.

Use this hook together with useContract to send transactions to the network in a type-safe way.

Usage

The following example shows how to transfer $STRK tokens to an address.

import {
  useSendTransaction,
  useContract,
  useNetwork,
  useAccount,
} from "@starknet-react/core";
import type { Abi } from "starknet";
 
const abi = [
  {
    type: "function",
    name: "transfer",
    state_mutability: "external",
    inputs: [
      {
        name: "recipient",
        type: "core::starknet::contract_address::ContractAddress",
      },
      {
        name: "amount",
        type: "core::integer::u256",
      },
    ],
    outputs: [],
  },
] as const satisfies Abi;
 
const { address } = useAccount();
const { chain } = useNetwork();
const { contract } = useContract({ 
  abi, 
  address: chain.nativeCurrency.address, 
}); 
 
const { send, error } = useSendTransaction({ 
  calls: 
    contract && address 
      ? [contract.populate("transfer", [address, 1n])] 
      : undefined, 
});
