Send Tokens - Para Docs

Send ETH and ERC-20 token transfers securely using Para’s wallet infrastructure.

Sepolia examples need testnet ETH before sending transactions. Get requestFaucetAsync from useRequestFaucet() and call requestFaucetAsync({ chain: "ETHEREUM_SEPOLIA" }) after the user has an EVM wallet. If chain is omitted, the faucet defaults to ETHEREUM_SEPOLIA. See Fund Testnet Wallet for the full example.

Wagmi is not available on React Native. Use Ethers.js or Viem for EVM operations.

Send ETH

import { useParaEthersSigner, useParaEthersSendTransaction } from "@getpara/react-native-wallet/evm/ethers";
import { ethers, JsonRpcProvider } from "ethers";
import { View, Text, TouchableOpacity } from "react-native";

const provider = new JsonRpcProvider("https://ethereum-sepolia-rpc.publicnode.com");

function SendETH() {
  const { ethersSigner } = useParaEthersSigner({ provider });

  const { sendTransactionAsync, isPending, data: receipt } = useParaEthersSendTransaction(ethersSigner);

  return (
    <View>
      <TouchableOpacity
        onPress={() =>
          sendTransactionAsync({
            to: "0x742d35Cc6634C0532925a3b844Bc9e7595f7BBB2",
            value: ethers.parseEther("0.01"),
          })
        }
        disabled={isPending}
      >
        <Text>{isPending ? "Sending..." : "Send 0.01 ETH"}</Text>
      </TouchableOpacity>
      {receipt && <Text>Transaction Hash: {receipt.hash}</Text>}
    </View>
  );
}

Send ERC-20 Tokens

import { useParaEthersSigner, useParaEthersWriteContract } from "@getpara/react-native-wallet/evm/ethers";
import { ethers, JsonRpcProvider } from "ethers";
import { Text, TouchableOpacity } from "react-native";

const ERC20_ABI = [
  "function transfer(address to, uint256 amount) returns (bool)"
];

const provider = new JsonRpcProvider("https://ethereum-sepolia-rpc.publicnode.com");

function SendToken({
  tokenAddress,
  decimals,
}: {
  tokenAddress: string;
  decimals: number;
}) {
  const { ethersSigner } = useParaEthersSigner({ provider });

  const { writeContractAsync, isPending, data: receipt } = useParaEthersWriteContract(ethersSigner);

  return (
    <TouchableOpacity
      onPress={() =>
        writeContractAsync({
          address: tokenAddress,
          abi: ERC20_ABI,
          functionName: "transfer",
          args: [

            ethers.parseUnits("10", decimals),
          ],
        })
      }
      disabled={isPending}
    >
      <Text>{isPending ? "Sending..." : "Send 10 Tokens"}</Text>
    </TouchableOpacity>
  );
}

Send ETH

import { useParaViemClient, useParaViemSendTransaction } from "@getpara/react-native-wallet/evm/viem";
import { parseEther, http } from "viem";
import { sepolia } from "viem/chains";
import { View, Text, TouchableOpacity } from "react-native";

  const { viemClient } = useParaViemClient({
    walletClientConfig: { chain: sepolia, transport: http() },
  });

  return (
    <View>
      <TouchableOpacity
        onPress={() =>

Send ERC-20 Tokens

import { useParaViemClient, useParaViemWriteContract } from "@getpara/react-native-wallet/evm/viem";
import { parseUnits, http } from "viem";
import { sepolia } from "viem/chains";
import { Text, TouchableOpacity } from "react-native";

      { name: "amount", type: "uint256" },
    ],
    outputs: [{ type: "bool" }],
  },
] as const;

  decimals,

  decimals: number;
}) {
  const { viemClient } = useParaViemClient({
    walletClientConfig: { chain: sepolia, transport: http() },
  });

  const { writeContractAsync, isPending, data: hash } = useParaViemWriteContract(viemClient);

  return (
    <TouchableOpacity
      onPress={() =>

        })
      }
      disabled={isPending}
    >
      <Text>{isPending ? "Sending..." : "Send 10 Tokens"}</Text>
    </TouchableOpacity>
  );
