Smart contracts powering HODL Helper, the app that helps believe in something and just HODL.
The onchain protocol is built around the concept of a "Lock". A Lock escrows any amount of a single token, along with a user-specified holding period.
To setup a Lock, a small fee of 0.00069 ETH is charged as part of the transaction. This fee helps fund the development of the app. It's pretty easy for infrastructure for the frontend and backend (planned for future) to need to scale with traffic, which costs money.
You can always add more tokens to an existing Lock, which again incurs the same small transaction fee (0.00069 ETH).
The tokens in a Lock can be withdrawn at any point, however, if withdrawn prior to the holding period ending, a 10% penalty is applied. This penalty is not applied if withdrawing after the holding period ends.
