Fixed the prettier in c9a4feb, unrelated to this PR though. I like to see build passing. |

I think the callout here needs some wordsmithing because you don't always need to select a provider. Probably something like "Some methods on Entropy require selecting..."

| a keeper service for fullfilling requests. | ||
|
|
||
| The simplest way to choose a provider is to use the [default provider](../contract-addresses). |

and the best way to get this is to call the getDefaultProvider() method on the contract. It's much better to use the method than hardcode the address (what if we change the provider??)

| You can use the onchain method [`getFee`](https://github.com/pyth-network/pyth-crosschain/blob/main/target_chains/ethereum/entropy_sdk/solidity/IEntropy.sol#L101) to calculate the fee for the default provider and send it as the value of the `requestWithCallback` call: | ||
| The fees differs for every chain and also varies over time depending on the chain's current gas price. |

Shouldn't we mention that getFeeV2() will use DefaultProvider?
