LIDO / 1inch co-incentivization integration

Smart-contracts that implements rewarding management for 1inch liquidity pool (a part of co-incentivization).

Flow

Deployment, initalization and usage flows are described in separate FLOW document.

Core contracts

RewardsManager.vy

Contract follows principles from other repositories: lidofinance/staking-rewards-manager, lidofinance/balancer-rewards-manager and lidofinance/staking-rewards-sushi.

Following parts are adapted for compatibility with 1inch liquidity protocol FarmingRewards contract:

• Added GIFT_INDEX constant. This is due to FarmingRewards contract requires manager contract to be aware of gift index (value dependends on order of addGift() call).
• Method _period_finish() adapted to obtain data from FarmingRewards.TokenRewards structure, that stores referenced reward data in FarmingRewards.tokenRewards state variable (of array type).
• Method start_next_rewards_period() adapted to transfer reward tokens to FarmingRewards instance address and trigger FarmingRewards.notifyRewardAmount() method. Key points:
  • FarmingRewards.notifyRewardAmount() requires tokens to be already transfered to FarmingRewards instance address.
  • Tokens are unable to be recovered after the operation.
