๐ ๏ธHow to Create & Deploy a DePIN on
@peaq (step-by-step guide)
Iโm sure thereโs someone reading this quoted post by peaq somewhere and thinking they want to be one of those but doesnโt know where to start. Iโm here for you๐ซ.
hereโs an opportunity for you to build something real world on peaq. So if youโre wondering how to create and deploy your own DePIN on peaq, this is for you.
letโs break it down step by step (read till the end)๐
1) Whatโs a DePIN anyway?
DePIN = real-world machines, such as EVs, sensors etc coordinated through blockchain.
on peaq, you get tools like DIDs (Decentralized IDs), machine wallets, and verifiable data to make this secure and autonomous.
2) Firstly, to set up your dev environment, youโll need Node.js. Then install the peaq SDK and ethers.js:
npm install peaq-network/sdk ethers
connect to the Agung testnet:
https: //peaq-agung.api.onfinality.io/public
peaqโs docs are really helpful. Make sure you test thoroughly first before deploying to mainnet.
3) Then you need to create a machine wallet. Each device in your DePIN gets a unique crypto identity.
example in JS:
import {Wallet} from "ethers";
const machineWallet = Wallet.createRandom();
donโt forget to keep the private key secure! In prod, consider HSMs or secure enclaves. This is a very important part.
then you need to fund the wallet. Machines need gas to operate.
then transfer peaqโs token,
$PEAQ to your device from an admin wallet:
const provider = new ethers.JsonRpcProvider("https: //peaq-agung.api.onfinality.io/public");
const admin = new ethers.Wallet("YOUR_ADMIN_PRIVATE_KEY", provider);
await admin.sendTransaction({
to: machineWallet.address,
value: ethers.parseEther("1")
});
4) Next is to build a DID Document.
This is like a digital passport for the machine. Would include both public keys and metadata.
const sdk = await Sdk.create({baseUrl: "wss://ws-agung.peaq.network"});
const didAccount = generateDid(machineWallet.mnemonic.phrase);
customize it with attributes like device model or geolocation as you deem fit.
5) Now sign the DID. Use the machineโs private key to authenticate the DID doc:
const signature = await machineWallet.signMessage(JSON.stringify(didDocument));
then remember to append the proof object to your doc. This makes sure itโs cryptographically verifiable.
6) Now you can upload to peaq. Use peaqโs built-in decentralized storage to persist the DID:
await sdk.did.create({
didDocument: JSON.stringify(didDocument),
keys: [{privateKey: machineWallet.privateKey, publicKey: machineWallet.publicKey}]});
you should get a hash after this, which is your machineโs on-chain ID anchor. Save it somewhere.
7) Now is the time to register the machine onchain. Do this by onboarding your device to your DePIN project:
await sdk.machine.register({
did: didAccount.uri,
metadata: {type: "sensor", model: "YourModel"}});
if youโre registering multiple devices, you can loop this. Solidity or Ink! smart contracts can be added here.
8) Then you build the core logic as you want it to be. Use smart contracts to manage incentives, data sharing, or governance.
sample contract:
contract DePINIncentives {
// Logic for rewarding data contributions}
test on Hardhat or Remix. Peaq supports both EVM and WASM, so youโre good.
9) Now you can finally deploy your infrastructure.
Pick your model:
~ Node.js backend for fleet management
~ React Native app for users
~ Next.js web dashboards
use Truffle or Remix to deploy contracts to peaq mainnet. APIs will connect machines to your backend/app logic.
donโt forget to monitor and iterate.
set up dashboards (Grafana, explorers).
watch for gas usage, security risks and community feedback
โข And thatโs how to build your DePIN on
@peaq.
