Sign Transaction

Using Sui adapter you can either sign a transaction and keep it for later sending, or sign and execute it consecutively.

info

To create a simple Sui account from public key, use the following function, using the @mysten/sui package.

import { publicKeyFromRawBytes } from "@mysten/sui/verify";

const createSuiWalletAccountFromString = (publicKey: string): WalletAccount => {
  const suiPk = publicKeyFromRawBytes("ED25519", bs58.decode(publicKey));
  return {
    address: suiPk.toSuiAddress(),
    publicKey: suiPk.toRawBytes(),
    chains: SUI_CHAINS,
    features: [
      "standard:connect",
      "standard:events",
      "sui:signTransactionBlock",
      "sui:signAndExecuteTransactionBlock",
      "sui:signMessage",
    ],
  };
};

To sign a transaction using the previously created adapter, we recommend you use the function signTransactionBlock() from the adapter. But first you need to create a transaction object that conforms with the type mentioned below.

import type { Transaction } from "@mysten/sui/transactions";

export interface SuiSignTransactionBlockInput {
  transactionBlock: Transaction;
  account: WalletAccount;
  chain: IdentifierString;
}

Now you can create both an account from your public key, and a transaction object.

import { Transaction } from "@mysten/sui";

const account = createSuiWalletAccountFromString(YOUR_PUBLIC_KEY);

const tx = new Transaction();
const coin = tx.splitCoins(tx.gas, [tx.pure.u64(100)]);
tx.transferObjects([coin], tx.pure.address(RECEIVER_SUI_ADDRESS));
tx.setSenderIfNotSet(RECEIVER_SUI_ADDRESS);

Finally you can sign the transaction.

await adapter.signTransactionBlock({
  tx,
  chain: "sui:testnet",
  account: account,
});

Or you can sign and execute it immediately, like so.

await adapter.signAndExecuteTransaction({
  tx,
  chain: "sui:testnet",
  account: account,
});
