How can I run Move Scripts?

Move scripts are supported in the Aptos TypeScript SDK, Aptos Wallet Adapter, and in the Aptos CLI.

Running scripts with the TypeScript SDK

To use a script with the TypeScript SDK, add the bytecode directly to the transaction in place of an entry function name.

import { readFileSync } from "fs";
import { Aptos, Account, AccountAddress } from "@aptos-labs/ts-sdk";
 
// Setup client, and account to sign
const aptos = new Aptos();
const account = Account.generate();
 
// Load script bytecode
const buffer = readFileSync("./transfer_half.mv", "buffer");
const bytecode = new Uint8Array.from(buffer);
 
// Build a transaction with the bytecode of the script
const transaction = await aptos.transaction.build.simple({
  sender: account.accountAddress,
  data: {
    bytecode,
    typeArguments: [parseTypeTag("0x1::aptos_coin::AptosCoin")],
    functionArguments: [AccountAddress.from("0x1")],
  },
});
 
// Submit and wait for the transaction to complete
const pendingTxn = await aptos.signAndSubmitTransaction({
  signer: account,
  transaction,
});
await aptos.waitForTransaction({ transactionHash: pendingTxn.hash });

Running scripts with the Aptos Wallet Adapter

⚠️

Not all wallets support scripts, but when the wallet supports scripts, it can be provided as below

Similar to the TypeScript SDK, the same inputs are accepted as a transaction type on the wallet adapter. Just simply load the bytecode as a hex string or a uint8array.

import { useWallet } from "@aptos-labs/wallet-adapter-react";
 
//...
 
// Load the bytecode either as a uint8array or a hex encoded string
const BYTECODE_IN_HEX = "0xa11ceb0b...78979";
 
export default function App() {
  const { signAndSubmitTransaction } = useWallet();
 
  function submitScript() {
    signAndSubmitTransaction({
      data: {
        bytecode: BYTECODE_IN_HEX,
        typeArguments: [parseTypeTag("0x1::aptos_coin::AptosCoin")],
        functionArguments: [AccountAddress.from("0x1")],
      },
    });
  }
 
  // ...
}

Running scripts with the CLI

Running scripts with the CLI can be run with the command

Terminal
aptos move run-script

There are two ways to run it, with a pre-compiled script, or it will compile the script in-place similar to the compile step.

If you already have a compiled script, you can run it with --compiled-script-path like the example below:

Terminal
aptos move run-script --compiled-script-path /opt/git/developer-docs/apps/docusaurus/static/move-examples/scripts/transfer_half/script.mv

Similarly, if it’s not compiled, just use --script-path

Terminal
aptos move run-script --script-path ./sources/transfer_half.move
