Vesting schedule

When creating a sale, issuers can integrate a vesting schedule to allow investors to get access to the token that is wrapped. Vesting is only compatible with ERC-20 wrapped tokens.

Vesting schedules are split into 3 sections:

1. Cliff that is the duration between the end of the sale and the beginning of the vesting schedule
2. Vesting length that is the duration of the vesting schedule
3. Claimable periods that is the amount of periods where the investor can claim the token
