Methods to Create a Twitter Bot for Crypto

Step 3 – Receive Actual-Time, On-Chain Knowledge with Moralis Streams

To make use of Moralis’ Streams API, you want a Moralis account. So, in case you haven’t finished so but, use the “create your free Moralis account” hyperlink within the intro. Along with your account prepared, you’ll have the ability to entry your admin space. There, choose the “Streams” tab. Subsequent, click on on the “Create a brand new stream” button:

Then, paste within the Tether sensible contract deal with (on this case, you may merely choose it among the many given examples):

Subsequent, it is advisable present some particulars contained in the “Stream Configuration” part:

You’ll be tying your stream and your Twitter bot collectively within the subsequent part utilizing the “index.py” script. Nevertheless, at this level, it is advisable get hold of your webhook URL. As such, run that script (not but in its ultimate kind) to create a easy server. These are the traces of code you want at this stage in your “index.py” script:

import json

from flask import Flask, request

import locale

from twitter_bot import send_tweet

locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')

app = Flask(__name__)

@app.route("/webhook", strategies=["POST"])

def webhook():

    # Course of the request information right here

    webhook = request.information.decode("utf-8")

    json_object = json.masses(webhook)

    print(json_object)

    return "OK"

if __name__ == "__main__":

    app.run(port=5002)

Use the next command to run the above script:

python index.py

Because of this, you should have a easy server operating on localhost 5002:

To lastly get your webhook URL, you should use ngrok for the above port (5002) with this command line:

ngrok http 5002

The above command will create a tunnel to your localhost and give you a URL deal with that you should use as your webhook URL:

Copy the deal with and paste it into the “Webhook URL” entry discipline (add “/webhook”). Additionally, enter an outline and tag:

Choose the Community and Receive the Sensible Contract ABI

Within the third step of your stream setup, you get to pick networks. Since Ethereum is toggled by default, you don’t must do something. In any case, Tether is an ERC-20 token based mostly on the Ethereum blockchain. Nevertheless, for those who had been to focus on different chains, you’d must toggle them on this step. 

Subsequent, be sure to solely choose the “Contract Interactions” possibility:

Within the “Superior Choices” part, it is advisable enter your sensible contract’s ABI (the one you need to take heed to):

So, use the Tether deal with and paste it into Etherscan’s search bar:

 Then, choose the “Contract” tab:

As soon as on the “Contract” tab, scroll down till you see “Contract ABI”, which accommodates the small print it is advisable copy:

As quickly as you paste the ABI into the entry discipline within the “Superior Choices” part, Moralis gives you with the accessible matters. Since we need to concentrate on USDT transfers, we have to choose the “Switch” perform: 

Since we need to concentrate on massive (whale) transfers, we should additionally implement an appropriate filter. That is the place the second snippet of code offered on the high of the article comes into play. Paste these traces of code and click on on “Replace”:

Lastly, swap your stream from demo to manufacturing:

Step 4 – Provide Your Twitter Bot for Crypto with the Info from Your Stream

At this level, you could have your Twitter bot prepared, and you’re getting the details about all USDT transfers bigger than a million. This implies you solely want to provide your bot with the knowledge that the above-created stream fetches. To attain this, you have to tweak your “index.py” script accordingly. 

For starters, you don’t want to print your complete response however concentrate on particular data. A “attempt” assertion will do the trick. You additionally need to outline the items of data the stream returns. That is the up to date “webhook” perform:

def webhook():

    # Course of the request information right here

    webhook = request.information.decode("utf-8")

    json_object = json.masses(webhook)

    attempt:

        switch = json_object["erc20Transfers"][0]

    besides IndexError:

        return "OK"

    sender = switch["from"]

    receiver = switch["to"]

    worth = switch["value"]

    token_name = switch["tokenName"]

    transaction_hash = switch["transactionHash"]

    handle_response_and_tweet(sender, receiver, worth,

                              token_name, transaction_hash)

    return "OK"

To make use of the above parameters in a tweet, we have to add one other perform – “handle_response_and_tweet” – into the “index.py” file:

def handle_response_and_tweet(sender, receiver, worth, token_name, transaction_hash):

    sender = sender[:6] + "..." + sender[-3:] + "..."

    receiver = receiver[:6] + "..." + receiver[-3:] + "..."

    worth = "${:,.6f}".format(float(worth)/1000000)

    transaction_hash="https://etherscan.io/tx/" + transaction_hash

    tweet = f"New Whale Alert! {sender} despatched {worth} {token_name} to {receiver}! in transaction {transaction_hash}"

    send_tweet(tweet)

The above “sender” and “receiver” traces guarantee we solely tweet the primary six and the final three characters of a sender’s and receiver’s addresses. In any case, tweets have a restricted quantity of characters. In the case of “worth“, the above code provides the USD image and codecs the quantity in accordance with the truth that USDT makes use of six decimals. So far as “transaction_hash” goes, it merely follows Etherscan’s format. Furthermore, “tweet” constructs the message that we wish our Twitter bot for crypto to tweet:

Notice: You possibly can entry the entire “index.py” script on GitHub.   

What’s a Twitter Bot?

A Twitter bot is a particular sort of app that has the facility to regulate a Twitter account. It does so by means of the Twitter API, which devs can entry by way of their Twitter developer portal accounts (as demonstrated above). Moreover, Twitter bots can carry out varied actions, together with posting tweets, re-tweeting, following, unfollowing, liking, and even direct-messaging different accounts. Out of those, the above tutorial confirmed you the best way to use a Twitter bot for tweeting.
