SDKs

Use official Aptos SDKs when an application signs, simulates, submits, or waits for transactions. The API overview points developers to SDKs alongside REST and indexing APIs (Aptos API documentation).

Language	Use	Sample
TypeScript	Web/backend app integration	chains/aptos/samples/typescript/client.ts
Python	Automation and ops tooling	Use REST for simple reads; SDK for signing flows
Rust	High-throughput services and native tooling	Prefer SDK/client crates for signing and BCS handling

import { Aptos, AptosConfig, Network } from "@aptos-labs/ts-sdk";

const aptos = new Aptos(new AptosConfig({ network: Network.MAINNET }));
const ledger = await aptos.getLedgerInfo();
console.log(ledger.ledger_version);
