The vesting contract holds tokens and releases them gradually over time according to a schedule, used for allocations that should not be immediately liquid (team, treasury, partners).

​
What it does

  • A schedule defines a start, a duration, and (optionally) a cliff before anything unlocks.
  • The amount claimable grows linearly with elapsed time; the beneficiary claims whatever has vested so far whenever they like.
  • Already-vested tokens cannot be clawed back.
This contract ships with tests.rs covering the unlock math, included below so you can verify the schedule behaves as described.

​
Interface

The schedule setup, claim, and query messages are in msg.rs; the release calculation is in contract.rs.
