Nevertheless, earlier than you may deal with creating your stream through the SDK, it’s worthwhile to put together a server. The latter will obtain a webhook. Thankfully, you may create a easy NodeJS Categorical app, which is able to offer you a “webhook” endpoint.
Create a Native Server
So, to that finish, you need to use the next strains of code – merely copy-paste them into your “index.js” file:
const specific = require("specific");
const app = specific();
const port = 3000;
app.use(specific.json());
app.put up("/webhook", async (req, res) => {
const {physique} = req;
strive {
console.log(physique);
} catch (e) {
console.log(e);
return res.standing(400).json();
}
return res.standing(200).json();
});
app.hear(port, () => {
console.log(`Listening to streams`);
});
Notice: In case you’ve by no means created NodeJS purposes and arrange Categorical servers, dive into our “Quickstart NodeJS” information.
With the above script in place, merely enter and run the npm run begin command utilizing your terminal.
In response to the above command, your terminal ought to return the “Listening to streams” message:
Create a Forwarding Tunnel
Subsequent, open a brand new terminal and run the ngrok http 3000 command. It will create a tunnel to port 3000. In response to this command, you’re going to get a URL handle to make use of as a webhook URL in your stream.
Along with your native server and tunnel prepared, you need to use the strains of code outlined within the upcoming part to observe varied on-chain actions. And, after all, the “tips on how to monitor all ETH switch transactions” feat can be one of many choices you may deal with.
Crypto Switch Monitoring – Code Walkthrough
Begin by initializing one other NodeJS app. Subsequent, create a brand new “index.js” file, which must require Moralis and dotenv:
const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");
require("dotenv").config();
As well as, it’s worthwhile to create a “.env” file. Inside that file, retailer your Moralis Web3 API key beneath the MORALIS_KEY variable. To acquire the worth of that variable, entry your Moralis admin space, go to “Settings”, and duplicate the default API key or create a brand new one:
Now that you’ve your API key, you may initialize Moralis. To take action, add the next strains of code beneath require (“dotenv”).config();:
Moralis.begin({
apiKey: course of.env.MORALIS_KEY,
});
Then, it’s time to deal with the stream’s choices with the next strains of code:
async operate streams(){
const choices = {
chains: [EvmChain.MUMBAI],
tag: "transfers",
description: "Hearken to Transfers",
includeContractLogs: false,
includeNativeTxs: true,
webhookUrl: "your webhook url"
}
Wanting on the above code snippet, you may see that it defines a series to deal with, an outline, a tag, and a webhook URL. These are all the identical choices we lined within the above part, as we used Moralis’ admin UI.
We are going to deal with listening to native transactions on the Mumbai testnet. So, we set includeContractLogs to false with a purpose to not hearken to ERC-20 transactions. Moreover, we deal with native foreign money transfers by setting includeNativeTxs to true. Concerning the Mumbai community, the native foreign money is “take a look at” MATIC.
To make use of the above strains of code in your “index.js” script, you simply want to interchange your webhook url with the beforehand generated ngrok URL:
As indicated within the above picture, be certain that so as to add /webhook on the finish of your ngrok URL.
Create a New Stream
By overlaying all of the above-outlined steps, you might be lastly able to implement the strains of code showcased within the introduction of this text.
As such, deal with the above-defined async operate streams and add the next snippets of code beneath the webhookUrl line:
const newStream = await Moralis.Streams.add(choices)
const {id} = newStream.toJSON();
const handle = "wallet_address_you_want_to_track";
await Moralis.Streams.addAddress({handle, id})
console.log("Fin")
}
streams()
The Moralis.Streams.add(choices) technique makes use of the above-defined stream choice to create a brand new stream. Subsequent, the code makes use of const {id} to fetch the brand new stream’s ID. Plus, it defines a pockets handle to observe. That is the place it’s worthwhile to change wallet_address_you_want_to_track with an precise handle.
The Moralis.Streams.addAddress technique makes use of your stream’s ID to assign the pockets handle to it. Lastly, the code logs Fin as soon as it completes all of the earlier steps.
To run your script, enter node index.js. In case you did the whole lot in keeping with the above directions, it’s best to see Fin in your terminal:
Native Foreign money Instance Transaction
Earlier than you go and execute a local foreign money transaction for testing functions, open your “Categorical server” terminal. There, it’s best to see an empty webhook initializing:
Now, use your MetaMask and switch some “take a look at” MATIC from or to the handle you might be monitoring. As soon as the transaction is confirmed, you’ll have the ability to see the small print of your take a look at transaction in your terminal:
And that’s tips on how to monitor all ETH switch transactions utilizing Moralis Streams through its SDK!
