Build on LightChain AI

One console for the whole SDK: run encrypted inference, chat, agents, batch jobs, worker operations, the bridge, and the DAO - each as a live, runnable panel, with the exact code to copy. Pick a capability on the left, or start below.

Playground GitHub

install

npm install lightnode-sdk viem

scaffold a new app

npm create lightnode-app my-app

Encrypted end to end. ECDH + AES-GCM with the worker. The SDK never sees plaintext after it leaves the caller.

Verifiable on-chain. Every call leaves createSession + submitJob + jobCompleted receipts anyone can check.

Non-custodial. Your key signs locally. No accounts, no hosted middleman, single peer dep (viem).

Five lines to your first inference

TypeScript

import { runInferenceWithKey } from "lightnode-sdk";

const { answer, txs } = await runInferenceWithKey({
  network: "testnet",                 // or "mainnet"
  privateKey: process.env.PRIVATE_KEY, // 0x... funded key
  prompt: "One fun fact about the ocean.",
});

console.log(answer);            // decrypted answer
console.log(txs.createSession); // verifiable on-chain receipts
