  • Developer experience Strongly typed APIs and Interfaces, autocomplete, comprehensive documentation.
  • Stability Test suite runs against Aptos fullnode and indexer with a local network
  • Transaction Builder Intuitive and simplified transaction builder flow
  • Serialization/deserialization support Full nested serialization/deserialization support and Move sub-classes to easily serialize and deserialize Move types

Installation​

 pnpm i @aptos-labs/ts-sdk

Quick Start​

Set up Aptos​

const aptos = new Aptos(); // default to devnet

// with custom configuration
const aptosConfig = new AptosConfig({ network: Network.TESTNET });
const aptos = new Aptos(aptosConfig);

Fetch data from chain​

const ledgerInfo = await aptos.getLedgerInfo();
const modules = await aptos.getAccountModules({ accountAddress: "0x123" });
const tokens = await aptos.getAccountOwnedTokens({ accountAddress: "0x123" });

Transfer APT coin transaction​

const transaction = await aptos.transferCoinTransaction({
  sender: alice,
  recipient: bob.accountAddress,
  amount: 100,
});
const pendingTransaction = await aptos.signAndSubmitTransaction({
  signer: alice,
  transaction,
});

Build and submit transaction​

// generate a new account key pair
const alice: Account = Account.generate();

// create the account on chain
await aptos.fundAccount({ accountAddress: alice.accountAddress, amount: 1000 });

// submit transaction to transfer APT coin from Alice to Bob
const bobAddress = "0xb0b";

const transaction = await aptos.transaction.build.transaction({
  sender: alice.accountAddress,
  data: {
    function: "0x1::coin::transfer",
    typeArguments: ["0x1::aptos_coin::AptosCoin"],
    functionArguments: [bobAddress, 100],
  },
});

// using sign and submit separately
const senderAuthenticator = aptos.transaction.sign.transaction({
  signer: alice,
  transaction,
});
const pendingTransaction = await aptos.transaction.submit.transaction({
  transaction,
  senderAuthenticator,
});

// using signAndSubmit combined
const pendingTransaction = await aptos.signAndSubmitTransaction({
  signer: alice,
  transaction,
});
