For investors unfamiliar with smart contracts in airdrops, start by learning the basics from online courses on platforms like Coursera or Udemy. Read the official documentation of the smart contract involved in the airdrop. Use wallets with built - in security features for smart contract interactions, like MetaMask with its safety checks. Before making any transactions, double - check all the details, including the recipient address and the amount of tokens involved. If possible, test the process with a small amount first.
