Airdrops Explained: How to Receive Them and Avoid Scams

An airdrop is a marketing method in which a project distributes tokens to users for free. This article covers claiming tokens, farming and wallet-draining scams that can take an entire wallet's assets.

What is an airdrop?

An airdrop occurs when a blockchain project gives its tokens to users for free. It is a marketing and community-reward mechanism for promoting a new coin and attracting early users. Although recipients do not pay for the distribution itself, they usually need to meet conditions such as holding assets in a wallet, having a trading history or completing tasks.

There are three broad types.

• Holder-based: Distributed to wallets holding a particular token or NFT at a specified time, using a snapshot.
• Activity-based: Distributed to users who trade, stake or complete social-media tasks.
• Retroactive: Rewards earlier use of a network after the fact. The source article cites Uniswap's 2021 distribution of 400 UNI to early users as a representative example, valued at several million Korean won at the time.

How to receive an airdrop

You generally need your own personal wallet. The usual process is as follows.

1. Check the requirements through trustworthy sources such as the project's official website and documentation.
2. Meet the required conditions, such as using the chain, trading a specified amount or staking.
3. After the snapshot, collect the tokens through the official claim page.

What is airdrop farming?

Airdrop farming means using a new project that has no token yet to build possible eligibility for a future retroactive distribution. Common activities include trading, providing liquidity and using bridges.

Farming does not guarantee returns. Failing to recover even the gas fees is common, so it is reasonable to commit only small amounts and time you can afford to lose.

Beware of scams, fake airdrops and wallet drains

Airdrops are a popular lure for scammers. A key technique is a wallet drain: a fake claim website persuades you to connect a wallet and sign a malicious request, allowing it to take your assets.

• Fake claim websites: Promoted through search ads or direct messages, often with a domain differing by just one character.
• Malicious signatures and approvals: Clicking 'claim airdrop' requests unlimited permission to withdraw tokens.
• Unknown tokens arriving in a wallet: A dusting tactic lures you to a website associated with unexpected tokens.

Safety rules

• Use official sources only. Avoid links in direct messages, comments or ads.
• Never enter or share a seed phrase or private key. A genuine airdrop does not require either.
• Read signature and approval requests and reject anything suspicious. Review and revoke token approvals regularly.
• Use a separate wallet for farming and testing, isolated from your main holdings.
• Do not visit a website or interact with a token simply because an unfamiliar token arrives in your wallet.

Airdrops offer both opportunity and risk. Understanding the risks and following verified procedures is the strongest protection for your assets. Also refer to capital-management principles when allocating funds.
