Microwallet refers to a temporary crypto wallet where faucet site owners can send small amounts of crypto to their users or claimers, then users can withdraw crypto to their personal wallets. The main purpose of Microwallet is to save faucet site owners costs when making transactions, either in the form of blockchain fees or transaction fees charged by crypto exchanges. Currently, many microwallets have been closed, so the only ones that still survive are Faucetpay and cWallet. Microwallet is only for storing small amounts of crypto, so users are not recommended to store large amounts of crypto, especially when participating in staking or Earning programs.
