Get Started with Avail DA
Post data to Avail DA and read it back — in TypeScript, Rust, or Go.
Avail DA is a modular data availability layer purpose-built so rollups can post, verify, and retrieve data without running a full node. Rollup teams across the ecosystem use Avail DA to scale throughput while keeping verification light and decentralized. On this page you'll install an SDK, submit data to the Turing testnet, and read it back — in under 5 minutes.
Quick Look — Submit & Read Data
import { Account, SDK, Block } from "avail-js-sdk";
const sdk = await SDK.New("wss://turing-rpc.avail.so/ws");
const account = Account.new("YOUR_SEED_PHRASE");
// Step 1: Submit data
const tx = sdk.tx.dataAvailability.submitData("Hello, Avail!");
const res = await tx.executeWaitForInclusion(account, { app_id: 89 });
console.log(`Block: ${res.blockHash} | Tx: ${res.txHash}`);
// Step 2: Read it back
const block = await Block.New(sdk.client, res.blockHash);
const blobs = block.dataSubmissions({ txHash: res.txHash });
console.log(blobs[0].toAscii()); // "Hello, Avail!"Note
Prerequisites: Before running the code above, you'll need:
- Testnet AVAIL tokens — free from the faucet
- An App ID — identifies your data namespace
- An SDK installed:
pnpm add avail-js-sdk·cargo add avail-rust·go get github.com/availproject/avail-go-sdk
