Execute Sui Transactions

Build, sign, and submit Sui transactions with Para

Build a Sui programmable transaction, sign it with a Para wallet, and submit it to the network.

Build, Sign, and Submit

The signer’s signTransaction signs the transaction bytes (intent-wrapped and hashed by @mysten/sui). Submit the transaction bytes and the resulting signature with the client.

import { useParaSuiSigner } from "@getpara/react-sdk";
import { Transaction } from "@mysten/sui/transactions";
import { SuiGrpcClient } from "@mysten/sui/grpc";

const client = new SuiGrpcClient({ network: "mainnet", baseUrl: "https://fullnode.mainnet.sui.io:443" });

function SendSui() {
  const { suiSigner } = useParaSuiSigner();

  const send = async () => {
    if (!suiSigner) return;

    // Split 1 MIST off the gas coin and send it back to ourselves.
    const tx = new Transaction();
    tx.setSender(suiSigner.address);
    const [coin] = tx.splitCoins(tx.gas, [1]);
    tx.transferObjects([coin], suiSigner.address);

    const bytes = await tx.build({ client });
    const { signature } = await suiSigner.signTransaction(bytes);

    const result = await client.executeTransaction({ transaction: bytes, signatures: [signature] });

    console.log("Digest:", result.Transaction.digest);
  };

  return <button onClick={send}>Send</button>;
}

Building the transaction resolves gas coins through the gRPC client, so the wallet must hold some SUI for gas. On testnet, fund the address from the Sui faucet.
