Airdrop

Key points

• An airdrop is the free distribution of tokens to addresses that meet criteria defined by the project, such as already holding a certain asset or having used the network.
• It serves to promote a project, expand its holder base, and decentralize ownership of a token newly launched on the market.
• It is a common vector for scams: fake airdrops trick people into connecting wallets or signing transactions that drain the user's funds.

What is an airdrop?

An airdrop is the delivery of digital assets to the public, either for holding another specific token or simply for being an active wallet address on a blockchain. The project defines eligibility rules and sends the tokens directly to qualifying addresses, without charging for the receipt itself.

How it works

The project sets a criterion and a reference date, called the snapshot, at which it captures the state of the network. Addresses that meet the rule at that moment enter the distribution list. Tokens can be sent automatically or made available for manual claim, when the user connects their wallet and claims their share.

Criteria vary. Some airdrops reward those who already hold a related asset, others reward prior use of the protocol, such as number of transactions or volume moved. There are also distributions tied to tasks, though these are closer to marketing campaigns.

On the project's side, the goal is usually to spread token ownership among many participants and stimulate early activity on the network. On the user's side, the value received depends entirely on liquidity and subsequent demand for the token.

There are also tax implications to consider. In Brazil, tokens received via airdrop may constitute an increase in net worth and be subject to reporting and taxation when sold, according to the rules applicable to virtual assets. Treatment depends on the value and timing of the disposal.

Why it matters

For those who actively operate with crypto, airdrops are a way to receive tokens without a direct outlay. A freelancer who already uses a network to receive payments may eventually qualify for a distribution tied to that activity. Even so, receiving tokens does not guarantee value: many distributed tokens have low or no liquidity.

Risks and limitations

Fake airdrops are one of the most frequent scams. Fraudulent sites ask users to connect their wallet and sign a transaction that, in practice, grants permission to transfer the user's funds. The practical rule is not to interact with unsolicited tokens that appear in the wallet and never sign transactions from unknown sources.

Another concern is tokens that appear spontaneously and lure the user into visiting a site to claim a supposed prize. These assets usually serve only as bait. Revoking old permissions granted to contracts and keeping larger funds in a separate wallet reduce exposure to this type of fraud.
