## Strategies <a href="#response" id="response"></a>

### EIP-1559 <a href="#response-example" id="response-example"></a>

For EIP 1559, we  provide 2 different fields for each strategy: maxFee (per Gas) and maxPriorityFee (per Gas). To compute these estimations, we look at the block history, compute three different percentiles for the rewards offered by the transactions in the blocks, and then calculate the average for each strategy.
