Staking & Multi-Rewards

Staking, yield farming and many other strategies, are methods for earning passive income through staking liquidity tokens into vaults or farms. Yield farming promises a return (y(t)), commonly paid in one token.

For the particular case of Pod, vaults are called PODs, and yield farming returns are paid in several tokens (i.e., multi-rewards).

The annualized yield depends on several factors including the rate of new reward tokens generated per block, the total redistributed rewards for staking (M(t)), and farm-specific multiplier (mt), the total liquidity staked in the farm (staked, Lstaked,t), and the price of the particular underlying asset (Pu). The creation rate of new rewards tokens is approximately 40 tokens every three seconds, leading to an annualized yield formula:

$$y_t = \left( \frac{365 \times 28,800 \times 40 \times m_t}{M_t} \right) \left( \frac{P_{\text{u}, t}}{L_{\text{staked}, t}} \right)$$

On the other hand, if new reward tokens are being added as incentives during the current staking period, the aggregate multiplier does not equal the sum of all multipliers across all vaults. Additionally, it defines the realized farm yield between time $t$ and $t+h$ based on the change in the price of POD and the yield over that period, adjusted for a 365-day year.

$$\frac{P_{\text{u}, t+h}}{P_{\text{u}, t}} \left( \sum_{n=1}^{h} \frac{y_{t+n-1}}{365} \right)$$
