ERC-7720: Deferred Token Transfer


The standard enables users to deposit ERC-20 tokens that can be withdrawn by a specified beneficiary at a future timestamp. Each deposit is assigned a unique ID and includes details such as the beneficiary, token type, amount, timestamp, and withdrawal status.


Sometimes, we need deferred payments in various scenarios, such as vesting schedules, escrow services, or timed rewards. By providing a secure and reliable mechanism for time-locked token transfers, this contract ensures that tokens are transferred only after a specified timestamp is reached. This facilitates structured and delayed payments, adding an extra layer of security and predictability to token transfers. This mechanism is particularly useful for situations where payments need to be conditional on the passage of time.
