Ethereum

Already asked on Twitter but let’s see if we get better answers here:

If you could add or change, any one feature on Ethereum, what would it be and why?

Token approvals. They're the #1 reason for drained wallets and just seems a security nightmare overall. Yes gas fees would be higher for NFT trades without approvals but that's a fair tradeoff I think. If gas is too high go to L2 or wait for danksharding.

I also don't like the idea that if I want to list one particular item from an NFT collection I need to give approval for the entire collection. That's just crazy. My comparison is Tezos, where nobody uses approvals. Instead listed tokens are sent to escrow contracts. Much safer overall.

Yeah agree, there is really no reason for the approve model any more, we already have better options.

I think we became waaaaay too sensitive to gas costs early on and made some bad design UX tradeoffs.
