ERC20DropVote
BASE: ERC20Votes EXTENSION: DropSinglePhase The ERC20Drop
contract uses the DropSinglePhase
extensions, along with ERC20Votes
. It implements the ERC20 standard, along with the following additions to standard ERC20 logic: - Ownership of the contract, with the ability to restrict certain functions to only be called by the contract's owner. - Multicall capability to perform multiple actions atomically - EIP 2612 compliance: See {ERC20-permit} method, which can be used to change an account's ERC20 allowance by presenting a message signed by the account. The drop
mechanism in the DropSinglePhase
extension is a distribution mechanism tokens. It lets you set restrictions such as a price to charge, an allowlist etc. when an address attempts to mint tokens.
