Stake
Stake (opens in a new tab) enables users to stake pairs of HDT and ETH/WETH to earn WETH.
There is no lock-up period and there is no fee for staking. Humble Donations makes no revenue from staking, we are just happy to have stronger liquidity. It's a win-win: you can enjoy your juicy yields while reducing the volatility of HDT.
Rewards
The WETH incentive pool (rewards) is funded by a sizable portion of the taxed value of donations, with the except of HDT which is taxless. It can be thought of as each time that a taxable donation is sent, the amount of WETH in incentive pool grows.
The amount of WETH in the incentive pool is updated quarterly because of limitations of UniswapV3. All users will be migrated to the new incentive at the start of a new quarter. The first incentive is planned for in quarter 2 of 2025, to allow for sufficient WETH to build in the incentive pool.
UniswapV3
Staking uses UniswapV3 with a custom WETH incentive. There is no liquidity pair token of HDT-ETH. Your position is handled by an ERC-721 (NFT) which gets minted when a user first interacts with staking.
UniswapV3 carries many advantages over the popularized UniswapV2 method of staking which is not covered in detail in this documentation page. For more info: https://www.coinsmart.com/blog/uniswap-v2-vs-uniswap-v3-whats-the-difference/ (opens in a new tab)
Due to the design of UniswapV3, there are often more transactions that are required to interact with your position. This is because both ERC-20 tokens being staked are interacted with separately, therefore, there are two approvals, one for each token, required for minting or increasing a position.
