Rewards are vested following the SushiSwap model (as of 09/03/2021), to align the long-term incentives between the protocol, its liquidity providers, and holders of the governance token. To this end, 1/3 of the NRV rewards are claimable immediately after emission, and the remaining 2/3 are emitted to a vesting token contract that will be unlocked in 6 months.
The details of this unlock will be decided only after discussion with and input from the community.
