Calculations

Using the example of the Stader-Kelp strategy, let us see how the calculation looks like:

• N: total number of users in a batch

• F: total fee in terms of ETH

$$F = (\text{baseGasLimit} + N*\text{marginalGasPerUser})*\text{gasPrice}$$

• E: total ETH staked into Stader

$$E = (\text{ETH}_{\text{user 1}} + \text{ETH}_{\text{user 2}} + \text{ETH}_{\text{user 3}} + .... )- F$$

• R: total rsETH received for a batch from Kelp

• rsETH distribution per user:

$$\text{rsETH}_{\text{user x}} = \frac{(\text{ETH}_{\text{user x}} - \frac{F}{N})}{E} * R$$
