uniswap-v3-staker

Fork of the canonical staking contract designed for Uniswap V3.

Adds tick bounds specified by the incentive creator. Enforces a min tick range for liquidity eligible to receive rewards.

Fork TODOS

  • Add minWidth (int24 minWidth) to IUniswapV3Staker.IncentiveKey struct for incentive creator to enforce a min tick range to incentivize
  • Add require statements below line 329 in _stakeToken() to check tick bounds are satisfied by token depositor looking to stake
  • Add convenience function createIncentiveWithMaxRange() that uses max tick range for incentives
