When farming, farmers will receive a new distribution of YFETH with every block. In the first genesis month of launch the rewards will be 0.04 YFETH per block, divided by the proportional share of the pool.
The exception to this was the "YFETH Party!" pool which had an additional 2x bonus.
After the first month the reward is set to drop to 0.02 YFETH per block which is 2x than genesis month and 10x lesser than ETH at 2 ETH per block.
The APY calculation is based on the return in ETH to the daily USD value, based on current block return annualized. It is not a fixed return, it is not a promised return, it is not financial advice. It is based on ETH returns.
