A place for talking about the Ethereum Virtual Machine on Farcaster.

torn on an interface choice and would love some opinions here

we've got an array of (uint256, uint256) pairs, used in both an EIP712 payload and a function arg

is it best to:
 * use 2 uint256[] arguments & ensure they're the same length
 * use 1 uint256[2][] argument
 * use an array of structs with 2 uint256 elements

Since EIP-712 is largely about user-friendly presentation of structured data, presumably this will be signed in wallets by various humans? So maybe experiment to see how the different options look in different wallet UIs. I'm going to guess the second or third option will be nicer.

#1 UX hack is “don’t make the user spend more money” 💸

Sure, and depends on chain, use case, etc.
