DID and seed, explained simply:

• DID: Your public agent identity. It starts with did🔑z6Mk... and can be shared.

• Seed: The private secret that controls that identity. Never publish or share it.

• This is not your crypto wallet seed phrase. Never enter a 12-word or 24-word wallet seed anywhere in this flow.

• There is no recovery service. If you lose the DID seed, you may permanently lose control of that identity.

How to get started:

1. Go to: https://floppysol.xyz/onboard

2. Generate one unique DID

3. Click Generate beside Mint a key.

4. Wait until a green check appears and a DID beginning with did🔑z6Mk... is displayed.

5. Click Copy Both, then save both lines securely in a notepad.

6. Check that you saved both the public DID and the 64-character private seed.

   Finish the visible onboarding checklist

   Continue from top to bottom. The page prepares and signs the required records for you; no code is needed.

   • Send the signed hello: Creates the first signed message from your DID.

   • Publish the DID note: Creates a durable public note that connects the record to your DID.

   • Introduce the identity in the lobby: Places a signed introduction in Technocore's common room.

   • Open a room of your own: Creates a room associated with your key.

   • Create the private room: Part of this helper's onboarding flow; it is labelled unverifiable by design.

   • Style the identity: Choose a colour if you want, then publish it.

Important: If you face this error, don’t create a new DID. The server is temporarily full or unavailable. Wait and click Publish again later.

Create something genuinely useful

The official task is not only about making a DID. Flop Labs also asked people to do something useful that helps Technocore reach or help more agents.

Beginner-friendly contribution ideas:

• Write an original X post explaining what a DID is in plain language.

• Create a short screen-recording that shows the onboarding flow.

• Test the onboarding flow and publish honest notes about what worked, what failed and how long it took.

• Create an FAQ that answers the questions beginners repeatedly ask.

What useful means here:

• Original: Use your own words and your own screenshots or examples.

• Practical: Give the reader something they can understand or do.

• Public: Keep the finished contribution accessible so it can be checked.

• Connected: Mention @flop_labs, Technocore and your public DID.

Connect the contribution to the same DID

• Publish your finished contribution first and copy its public URL.

• Open the FloppySol room.

  

• If the identity is not remembered, restore it using your saved DID and seed in the right-side panel.

• Choose signed mode near the message box.

• Post one clear message containing your contribution URL and a short explanation of what it helps people do.

• Do not include the private seed. The public DID is enough.

Suggested signed message

Final checklist

• I generated my own unique DID.

• I securely saved the DID and private seed.

• I completed the visible onboarding flow.

• I created an original and useful public contribution.

• I connect the contribution to the same DID.

• I included my public DID, not my private seed.

  ---

You’re done

If you completed the checklist above, you now have:

• A unique Technocore DID.

• A securely saved private seed.

• An original public contribution.

• A signed Technocore message connecting that contribution to your DID.

Creating a DID and contributing does not guarantee an airdrop allocation. Final eligibility, rewards and claim details can only be confirmed by @flop_labs.

That’s it. Keep it original, make it useful and avoid spam.

My public DID: did🔑z6MkngD8RZKCgJQCkJvHfGyYoCcNCG5rz9Tc7yRmWrMZExaz

This tutorial will walk you through the steps to become a verifier, explore what’s required, and explain how it might unlock exciting opportunities in Nillion’s ecosystem. Let’s dive in and get you started!

Steps required:

1. Buy a VPS

2. Complete “Secrets”

3. Be a Verifier

Buy a VPS:

• Go to: https://pq.hosting

• Register for an account on PQ Hosting. If you already have one, just sign in.

• Next, navigate to “Products/Services” and select “Virtual Private Servers”.

• Now, click on “Order” 👇🏻

• Order the cheapest VPS 👇🏻

• Select “Ubuntu 22.04” as the operating system and click on “Pay”.

• Select cryptocurrency as your payment method and complete the transaction.

• Once the transaction is complete, navigate to the 'Virtual Private Servers' page.

• There, you'll first see either 'Ordered' or 'Activating'.

• After a few minutes, the status will update to 'Active'.

• If more than an hour passes and the status hasn’t changed to 'Active', reach out to support for assistance.

• After activation, click the three dots next to the server you purchased, then select 'To panel'.

• On the new page, click the three dots and set a new password by selecting 'Change password'. Remember to save your password securely.

You've successfully set up the VPS. Now, let's proceed to the 'Secrets' task.

Complete “Secrets”:

• Go to: https://verifier.nillion.com

• Connect your Kepler and EVM wallets (such as MetaMask), then click 'Secrets'.

• Next, complete all the tasks on this new page. These tasks involve uploading a photo of your palm, your Nillion wallet address, a selfie, and your mother’s maiden name or place of birth.

• If you don’t have a Nillion address set up in your Keplr wallet, refer to this guide.

• After completing the 'Secrets' task, return to the previous page and select 'Verifier'.

Be a Verifier:

• Select “Linux” 👇🏻

• Now download and install the PuTTY software.

• If you’re a Mac user, you can use Termius:

Free SSH Client for macOS

Modern SSH Client for macOS that will make you more productive. Termius will save you up to 30 mins a day.

https://termius.com

• Open PuTTY or Termius and paste the IP Address of your VPS. You can find your IP address on the PQ hosting dashboard page.

• Then go to “Connection”.

• In the field beside Seconds between keepalives, enter 5.

• Check to Enable TCP Keepalives (SO_KEEPALIVE option) and click on “Open”.

• Now a new window will open

• Here, login as “root”.

• Paste the password (which you saved from your VPS details).

• Keep in mind that you won't see the password as you type it. Just type it in and hit Enter.

• Once you enter the password correctly, you will see a window like this 👇🏻

• If you're setting up your VPS for the first time, it may not have Docker installed. To get the latest Docker version, run the following commands one by one.

  👉🏻 To paste the commands into the PuTTY terminal, copy the code below, right-click in the terminal, and then press 'Enter' on your keyboard.

  👉🏻 If prompted with a Y/N option, type “Y” and press Enter. Type “1” and press Enter if asked to choose a number.

sudo apt update

sudo apt install apt-transport-https ca-certificates curl software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update

sudo apt install docker-ce docker-ce-cli containerd.io

sudo systemctl start docker sudo systemctl enable docker

Check that Docker is installed and up-to-date by running this command:

docker --version

You should see a version number that is the same as or higher than the one below.

• Now run this command:

docker pull nillion/verifier:v1.0.1

• Then the following command:

mkdir -p nillion/verifier

docker run -v ./nillion/verifier:/var/tmp nillion/verifier:v1.0.1 initialise

This will provide you with your verifier account ID and public key.

• Copy and save it securely.

• Go to the Nillion verifier page, paste your verifier account ID and public key, and complete the verifier connection.

• Approve the transaction in your Keplr wallet. If you don’t have faucet in your Keplr wallet on the Nillion chain, you can claim it here.

• When it succeeds, a 'Verifier Registered' message will appear.

• Now, go to the faucet page again: https://faucet.testnet.nillion.com

• Claim the faucet to the Nillion wallet you recently saved.

• Finally, run the following command:

docker run -v ./nillion/verifier:/var/tmp nillion/verifier:v1.0.1 verify --rpc-endpoint "https://testnet-nillion-rpc.lavenderfive.com"

You should see a screen like this 👇🏻

• Close the registration page.

• You should see a page like this 👇🏻

• Wait for 10 to 12 minutes, then refresh the page. You should see a page like this.

• If everything looks good, close the PuTTY software.

• Next, click on the 'Stake ETH' button.

• Deposit your desired amount of ETH. Supports Ethereum mainnet only.

• There’s no minimum requirement, but a larger amount is recommended for better results.

That's it! You've successfully completed the Verifier task.

Note: You can withdraw your ETH anytime, but be aware that this will lower your staking impact. It's best to keep your funds deposited until the verifier event is live or until the Nillion airdrop.

What is Taiko?

Taiko is a decentralized Layer 2 blockchain protocol that uses a Zero Knowledge Ethereum Virtual Machine (ZK-EVM). It is designed to be the most Ethereum-equivalent and general-purpose Zero Knowledge Rollup (ZK-Rollup).

The main objective of Taiko is to provide a scalable and efficient platform for decentralized applications (dApps) developers and users, allowing them to leverage the power of Ethereum Layer 1 (L1) without having to make any changes to their existing dApps.

Why would you want to run a node on Taiko Aplha 3 Testnet?

Running a node on the Taiko Alpha 3 Testnet offers several enticing benefits. Firstly, the testnet is designed as an incentivized platform, meaning that participants who run a node have the opportunity to be eligible for the Taiko airdrop. By actively engaging in the testnet, individuals can increase their chances of receiving a rewarding airdrop.

Moreover, participating in the testnet allows users to familiarize themselves with the intricacies of the Taiko network and gain valuable experience in operating a node. This hands-on involvement not only enhances one's understanding of the ecosystem but also positions participants to potentially contribute to the development and stability of the network in the future.

Now that we understand the significance of Taiko and the motivations behind running a node, let's dive into the practical aspects of setting up a node on the Taiko Alpha 3 testnet using a Virtual Private Server (VPS).

To run a node, we can divide the whole process into 2 parts:

1. Buy a VPS

2. Run Node

1. Buy a VPS

You can buy a VPS server from any service provider. But in this tutorial, we are using, PQ Hosting.

• First, create an account: Click here

• Once registered, go to “Products/Services” > “Virtual private servers”

• Now click on “Order” 👇🏻

• Now select any country and order “Rhodium, vCore x16, 16 GB RAM ECC, 200 GB SSD NVME”.

• You can select a lower configuration as well, but as per Taiko’s announcement, we need 16GB+ RAM for the best result.

• Now select “Ubuntu 22.04” as the operating system and click on “Add to cart”.

• Now enter our promo code AIRDROP_ADV to get 15% OFF and click on “Pay”

• Finally, make the payment. You can pay using different options which include crypto as well.

• Once you made the payment, go to the “Products/Services” > “Virtual private servers” section.

• There you’ll first see “Ordered”.

• After a few minutes, it will change to “Active”.

• If it has been more than an hour or so, and the status still does not show as 'Active', please contact support. They will assist you.

• Once activated, open the server details by double-clicking on the server name.

• Now copy the IP Address and Password and save it securely.

2. Run Node:

Now it’s time to run the node. For this, we will use the “PuTTY” software for Windows.

You can download it here:

If you’re a Mac user, you can use Termius:

Free SSH Client for macOS

Modern SSH Client for macOS that will make you more productive. Termius will save you up to 30 mins a day.

https://termius.com

• Once downloaded, install and open the software.

• Paste the IP Address of your VPS 👇🏻

• Then go to “Connections” >

• In the field beside Seconds between keepalives, enter 5 >

• Check to Enable TCP Keepalives (SO_KEEPALIVE option) and click on “Open” 👇🏻

• Now a new window will open

• Here, login as “root” 👇

• And paste the password (which you saved from your VPS details).

• Keep in mind, to paste any text within the PuTTY terminal, you just need to right-click and press “Enter” on your keyboard.

• Once you enter the password correctly, you will see a window like this 👇🏻

Now run these commands one by one:

• sudo apt update && apt upgrade -y

• sudo apt install pkg-config curl git-all build-essential libssl-dev libclang-dev ufw

If asked Y/N, type “Y” and hit enter.

• sudo apt-get install ca-certificates curl gnupg lsb-release

• sudo mkdir -p /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

• echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

• sudo chmod a+r /etc/apt/keyrings/docker.gpg sudo apt-get update

• sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

• sudo apt install docker-compose

If asked Y/N, type “Y” and hit enter.

To check the Docker Engine installation is successful, use this command:

sudo docker run hello-world

You should see something like this 👇

Now go to Alchemy:

Now it’s time to install and run the node:

Use this command to download the node:

• git clone https://github.com/taikoxyz/simple-taiko-node.git cd simple-taiko-node

Configure the node:

• cp .env.sample .env

Then use vim .env if you’re on Linux or nano .env if you’re on Mac.

This page will appear 👇

Now scroll down and delete the false in ENABLE_PROVER and replace with true.

If you’re not able to type directly in Putty, just type in Notepad, copy and right-click to paste.

Now go to Alchemy and copy the HTTP & WS and paste the links as shown below 👇

Now go to your Metamask wallet, and copy your private key (not the seed phase).

And paste at L1_PROVER_PRIVATE_KEY, as shown below 👇

To save the changes and exit Vim, press the Esc key.

Then, type the following command: :wq and hit enter.

Finally, use this command to run the node: docker compose up

Once entered, the node should start running and you will see a window like this 👇

Congrats!!! 🎉 You’ve successfully set up the node for Taiko Alpha 3 Testnet.

View the node's logs: docker compose logs -f

FAQs:

❓Can we close the Putty window after the setup is completed?

• Of course, you can close right after the setup is completed. You can even turn off your PC. This is why we used a VPS.

❓How long do we need to run the node?

• There is no specific guideline as we are not sure when Taiko provides a new update. But my plan is to run this node for 2 months.

❓Can we run this node with the same VPS we run for other nodes?

• No. Have to set up a brand new VPS.

What is Starknet?

StarkNet is a permissionless decentralized zk (zero-knowledge) rollup that offers scalable solutions for users within a secure Ethereum-like state. It fundamentally operates as an L2 (layer-2) network over the Ethereum blockchain and allows any DApp (decentralized application) to achieve unlimited scale for its computation without compromising security and composability.

Why would you want to run a node on Starknet?

Well, running a node on the Starknet mainnet comes with several benefits. Firstly, as a node operator, you actively contribute to the network's decentralization and security. Your node helps validate transactions, maintain consensus, and propagate information across the network, thereby strengthening the overall infrastructure.

Secondly, running a Starknet node can also qualify you for the potential $STARK airdrop. Depending on the network's governance model, node operators may be rewarded with a $STARK airdrop for their contributions. This allows you to potentially earn passive income by simply operating a node and supporting the Starknet ecosystem. However, there is no official confirmation on it, which means it’s purely speculative at the moment.

Now that we understand the significance of Starknet and the motivations behind running a node, let's dive into the practical aspects of setting up a node on the Starknet mainnet using a Virtual Private Server (VPS).

To run a node, we can divide the whole process into 2 parts:

1. Buy a VPS

2. Run Node

1. Buy a VPS:

You can buy a VPS server from any service provider. But in this tutorial, we are using, PQ Hosting.

• First, create an account: Here

• Once registered, go to “Products/Services” > “Virtual private servers”

• Now click on “Order” 👇🏻

• Now select any country.

• Due to higher demand, some countries may take several hours to days to activate. If you face this issue, contact the support team, and they will help you out.

• Select “Palladium, vCore x4, 8 GB RAM ECC, 80 GB SSD NVME” 👇🏻

• Select “Ubuntu 22.04” as the operating system and click on “Add to cart” 👇🏻

• Now enter our promo code AIRDROP_ADV to get 15% OFF and click on “Pay” 👇🏻

• Finally, make the payment. You can pay using different options which include crypto as well 👇🏻

• Once you made the payment, go to the “Products/Services” > “Virtual private servers” section.

• There you’ll first see “Activation in progress” 👇🏻

• After 5-10 minutes, it will change to “Active” 👇🏻

• If it’s more than an hour or so, and the status is still showing “Activation in progress”, contact support. They will help you out.

• Once activated, open the server details by double-clicking on the server name 👇🏻

• Now copy the IP Address and Password and save it securely.

2. Run Node:

Now it’s time to run the node. For this, we will use the “PuTTY” software. You can download it here:

Mike Yeadon: Final Warning

This page has been experiencing publicity, so I'm using it for a cause which I believe will serve the common good. This is the latest interview with Mike Yeadon. "I am a lifetime research scientist. I worked for 32 years in the pharmaceutical industry and biotech. My most senior positions were at Pfizer.

https://www.putty.org

• Once downloaded, install and open the software.

• Paste the IP Address of your VPS 👇🏻

• Then go to “Connections” >

• In the field beside Seconds between keepalives, enter 5 >

• Check to Enable TCP Keepalives (SO_KEEPALIVE option) and click on “Open” 👇🏻

• Now a new window will open

• Here, login as “root” 👇

• And paste the password (which you saved from your VPS details)

• Keep in mind, to paste any text within the PuTTY terminal, you just need to right-click and press “Enter” on your keyboard.

• Once you enter the password correctly, you will see a window like this 👇🏻

Now go to Alchemy:

Alchemy - the web3 development platform

Whether you're a beginner developer, startup, web3 market leader, or a large enterprise, Alchemy makes multichain web3 development easy.

https://www.alchemy.com

Sign in or Sign up if you don’t have an account already.

And click on “CREATE APP” 👇

Name: Set any random name (does not matter)

Chain: Ethereum

Network: Ethereum Mainnet

And create the app.

Now click on “View Key” 👇

And copy the HTTPS link 👇

Now replace “YOUR_ALCHEMY_HTTP_ADDRESS” with your HTTPS link on the below code 👇

ALCHEMY=YOUR_ALCHEMY_HTTP_ADDRESS echo 'export ALCHEMY='$ALCHEMY >> $HOME/.bash_profile

For example:

ALCHEMY=https://eth-mainnet.g.alchemy.com/v2/xxxxxxxxxxxxxxxx

echo 'export ALCHEMY='$ALCHEMY >> $HOME/.bash_profile

Now open PuTTY and paste the above code 👇

And hit Enter.

Now paste this code and hit enter:

wget -O starknet.sh https://api.nodes.guru/starknet.sh && chmod +x starknet.sh &&./starknet.sh

The installation will start and you’ll see a window like this 👇

If you see any error like this 👇

Just put “1” and hit enter.

Expect the entire process to take up to 20-30 minutes or even more to complete.

Once completed, you will see a page like this 👇

If you can see this page, congratulation, you’ve successfully set up a node on Starknet. 🎉

A few questions you may ask:

❓ Is it a confirmed airdrop for node runners?

No! There is no official announcement of airdrop to node runners. But this is the beauty of such mega airdrops 😁

❓ How to claim the airdrop as there is no wallet address involved?

There is no announcement yet, but if they do reward the node runners, most likely they will provide a way to connect our VPS with our wallet in future. So we will need to keep the VPS running till the airdrop is announced.

❓ Can we run this node with the same VPS we run for other nodes?

No. Have to set up a brand new VPS.

❓ Can we run this on mobile or Mac?

Yes. But need different software.

• For Mac, use this.

• For iPhone, use this.

• For Android phones, use this.

Optimism has recently utilized Gnosis Safe as a multiplier to maximize airdrop rewards, and we will walk you through the steps to set up and use Gnosis Safe to enhance your chances of receiving the zkSync airdrop. So, let's dive in and unlock the full potential of your airdrop with Gnosis Safe!

🔎 What is Safe (Previously known as Gnosis Safe)?

Safe, formerly known as Gnosis Safe, is a popular Ethereum-based wallet and smart contract platform developed by Gnosis, a leading blockchain technology company. Safe is designed with a strong focus on security, allowing users to manage their digital assets with peace of mind.

It features a multi-signature (multi-sig) wallet functionality, where multiple parties must approve a transaction before it can be executed. This adds an extra layer of security and makes it ideal for organizations or groups that require enhanced security measures and governance for managing their digital assets.

🚀 How to use Safe?

• Create a wallet on Safe

• Deposit fund

• Use dapps through Safe

⚡️ Create a wallet on Safe:

• Go to Safe 👇

Safe{Wallet}

Safe{Wallet} is the most trusted smart account wallet on Ethereum with over $100B secured.

https://app.safe.global

• Click on “Create a new safe”.

• Connect your wallet.

• Give a name and click on “Next”.

• Again enter the name of the owner of the wallet.

• Then click on “Add new owner”.

• And add 2 more new wallet addresses.

Make sure to use a wallet address that is added to the same browser wallet 👇

• Now change the threshold to 2 and click on next 👇

• Now final step: Click on next and confirm the transaction 👇

• Once the txn is successful, your Safe is ready to be used.

Keep in mind, that we’ve used Ethereum chain for this task. But you can use any other chain you want, like zkSync Erra, Polygon zkEVM, Base, Arbitrum, Polygon, Optimism, etc.

To create your Safe on a different chain, just change the chain on the right top corner while setting up your wallet 👇

⚡️ Deposit fund:

• To deposit funds to your Safe wallet, click on the copy icon 👇

• And send funds to this wallet address.

Make sure to edit the first part of the address, as it automatically adds the network ticker at the beginning of the address. For example, 'eth:0x******00'. From here, remove the 'eth:'.

⚡️ Use dapps through Safe:

Head over to the 'Apps' page and choose any dapp you would like to use. If you're new to Safe, we recommend starting with Uniswap or Sushiswap. Once you become familiar with Safe, you can explore other dapps.

For this tutorial, we are using Uniswap.

• Open Uniswap

• Choose tokens for swapping 👇

• And click on Approve/Swap

• Now click on “Submit” 👇

• And sign in to the txn. You may need to sign in the txn 2 times.

• Once sign-in is done, change your wallet to one of the other 2 wallets that you added while setting up your Safe account.

• Now click on the bottom tab to open the txn details 👇

• And confirm the txn 👇

After the transaction is confirmed, congratulations! You have successfully completed a swap on Safe using Uniswap! 🎉

Now, make sure to explore other dapps such as Sushiswap, 1inch, etc. using Safe. Additionally, we recommend trying out Safe on multiple chains like zkSync Erra, Polygon zkEVM, Base, Polygon, Optimism, etc while prioritizing the use of Safe on the Ethereum mainnet.

Head over to the “Solidity compiler” tab and hit on “Compile” 👇🏻

If there is no error, you will see a green check mark 👇🏻

Now it’s time to deploy the contract. But before that, switch the chain to ConsenSys zkEVM testnet on your Metamask. Make sure to hold some test ETH as we’ll need it for the gas fee.

If you haven’t added the chain yet, check this guide first. Adding the chain is not straightforward as we need an API key to add it. (Need to create an account on Earn3 first to access the guide.)

If you don’t have test ETH on ConsenSys zkEVM testnet, bridge some using the official bridge from Ethereum Goerli 👇🏻

https://bridge.goerli.zkevm.consensys.net/

Now go to the “Deploy page” > Choose “Injected Provider” on ENVIRONMENT and click on “Deploy 👇🏻

And confirm the transaction on Metamask 👇🏻

Once the transaction is successful, you’ll see your deployed contract like this 👇🏻

Congrats!!! 🎉🚀 You’ve successfully deployed a contract on the ConsenSys zkEVM testnet!!! This may come in handy later when ConsenSys launches it on the mainnet.

That’s it for now. Make sure to join us on Telegram to remain updated with ConsenSys airdrop and more.

Before we start:

- Make sure to add the Shardeum Sphinx testnet to Metamask first.
You can add it from here.

- And claim faucets on their Discord server.
Go to the “faucet-1.1” channel and type /faucet and enter your wallet address.

All set? Let’s begin the process then!

First, go to Openzeppelin. Openzeppelin is a web-based application that allows developers to perform and automate smart contract operations in an easier & secure way.

https://docs.openzeppelin.com/contracts/4.x/wizard

Now give the name of your token, token symbol, and token supply.
Eg. Token name = Shardeum, Symbol= SHM, Premint= 10000000

And click on “Open in Remix” 👇🏻

This page will open 👇🏻

Go to the “Solidity Compiler” page (3rd option on the left)

And click on the “Compile contract” button 👇🏻

If there is no error, you’ll see a green check mark on the “Solidity Compiler” button 👇🏻

Now go to the “Deploy” page (4th option on the left)

- Choose “Injected Provider” on the ENVIRONMENT option.

- Once selected, a popup will appear to connect your Metamask wallet. (If you used Remix before, it will auto-detect your wallet, no need to connect again)

Now click on the “Deploy” button 👇🏻

A Metamask pop-up will appear to confirm the transaction. Just approve it!

Once the transaction is successful, you’ll see your deployed contract 👇🏻

Congrats!!! 🎉🚀 You’ve successfully deployed a contract on the Shardeum Sphinx testnet!!! This may come in handy later when Shardeum launches on mainnet and do their token airdrop!

P.S. If the transaction fails, try increasing the gas to 20 or even more. If the issue still remains, try after a few hours or days.

That’s it for now. Make sure to join us on Telegram to remain updated with Shardeum airdrop and more.
