Airdropping has also shown application in projects which want to reward existing members with even more utility.

In this article, we will explore how to go about creating the two most common types of airdrops:

The on-chain direct mint and transfer drop The off-chain allowlist We will build the former using Solidity and standard OpenZeppelin ERC721 contracts. For the latter, we will employ digital signatures and the OpenZeppelin ECDSA library.

Finally, we will also write a script that leverages the [Alchemy NFT API][./] to get a list of all wallets that own an NFT of a particular collection.

Part 1: Direct Mint and Transfer In the direct mint and transfer model, the creator of the project mints the NFTs directly to a certain selection of wallets.

Step 1: Install Node and npm If you haven't already, install node and npm on your local machine.

Make sure that node is at least v14 or higher by typing the following in your terminal:

How can i help with Blockchain?

The human mind is governed by several factors in which compassion is one and the most compassionate of them all. Though everyone seems to wake up every day with a goal in mind to achieve their desired destiny and capacity a lot of people also miss out on the purpose of being charitable in their quest for survival.

Slightly know about what is Charity?

Firstly, I would define this in the context of CSR: Corporate social responsibility is a form of international private business self-regulation, which aims to contribute to societal goals of a philanthropic, activist, or charitable nature by engaging in or supporting volunteering or ethically-oriented practices. This can also come from individuals who see the need to help others especially those in difficult situations and trying challenges.

These charitable activities can be deployed in various forms, which include but are not limited to educational scholarships, water supply in poor communities, healthcare and so much more. Such organizations have shown that there is a need to support such communities in every little way possible to give the community a better quality of life.

Bitcoin is a secret in itself, lot's of people don't know about of the Bitcoin, how is it work😕 here most interesting topic is Bitcoin ATM.

So, today i am going to explain about of the Bitcoin ATM.

Bitcoin ATM is the part of Crypto Currency, In order to fight illicit activity related to Bitcoin, United States based Bitcoin ATM operators have announced the launch of Cryptocurrency Compliance Cooperative. The cooperative aims to establish compliance standards for the Bitcoin ATM industry. It will also create a safer environment for all consumers and legitimize the cash to cryptocurrency industry by bolstering compliance standards that are deemed by many to be currently insufficient. 

Commenting on this development, Seth Sattler, Director of Compliance for DigitalMint and leading member of the Cryptocurrency Compliance Cooperative said, 

 While a small number of Bitcoin ATM operators go above and beyond with know your customer (KYC) and anti-money laundering (AML) protocols, others in the cash-to-crypto industry simply turn a blind eye and are complacent to these bad actors by simply applying the bare minimum customer protections, which in many cases allow for completely anonymous transactions.

The problem plaguing this industry are well documented by several law enforcement agencies, and include fraud, elder abuse, and drug and human trafficking, Sattler added.  In the State of New Jersey Commission of Investigation report it was found that nearly 50% to 75% of the BTM operators with kiosks allowed transactions to take place with just a cellphone number, or in some cases, no information at all.
