What's the benefit of using a mutation over something like useCallback, or adding this to createSolanaClient?

[JkrishnaD]

@macalinao here we used useMutation because it is a state changing rpc-call as we are sending the transaction on-chain which changes the state. so i have used it there

Hey! Nice work on this hook 🎉

Just noticed a small naming issue: the parameter signature in line 19 should probably be wireTransaction or transaction instead.

Currently it's a bit confusing because:

• We're passing IN a transaction (base64 encoded)
• We're getting OUT a signature (the transaction ID)

Using signature for the input makes it seem like we're passing in a signature, when we're actually passing in the whole transaction. What do you think about renaming it?
