@profgalloway France 62 is plain and simple wrong. French citizen can retire at 62 iff they worked for 43 years. That means starting at 19 and having no unemployment period. If you study after 19, and start working at 23, you won't be able to retire at 62.

As a solidity developer you should always ask yourself. How big does the ID needs to be? do I expect billions of billions of users? How much value are user going to send? Do I expect hundreds of thousands of ETH? This struct could easily fit in one slot!

@cjremus @ratedw3b - Coinbase and Lido could prevent finality, but not halt the chain - You need 66% to force finalization of invalid blocks, but that doesn't mean you'd change Ethereum governance. In that case Ethereum governance would probably start a fork without these bad actors.

@PaulRBerg My personal opinion is that reentrancy guard is the lazy option. You use it when you don't want to properly fix you app invariants before doing external calls. That is also a sign you don't care about your app composability.

Ok, I'm going to say it out loud. For ERC20 transfer and calls: - Stop trying to come up with new standards. - Stop using approaches that are not standard. - Just use ERC-1363 It's clear! It's simple! It works! By not using it you are actually hurting everyone.

Change my mind: Decimals is only for off-chain displays. It has no impact onchain. Every operation (transfer, wrapping, ...) should only consider "units" (wei). Therefore decimals should have no effect on smart contract composition with ERC-20.

When I said I had doubts about 3074, and that we should be exploring for a better option, … that was not received well. Yet here we are. Don’t get it wrong, there is a lot to figure out about 7702, but it feels like everybody is once again going in the same direction !

EIP-7702 is heavy inspired by previous work and discussion, including the years of EIP-3074 saga/debate/drama. While the initial draft was indeed written very fast, it is the result of a long process, and it continues to evolve... Good stuff takes time, even when VB is involved

So Vitalik wrote EIP-7702 in 22 minutes, and the whole EIP-3074 saga has now ended because 3074 will be replaced with 7702 (which is 100x better)?

How much time would you lose chasing for this? I lost 1h, but a few years ago I would easily have lost an entire day ...

@LenaDormeau L'ENS Ulm tire son nom de la rue l'Ulm ou elle se trouve. La rue d'Ulm tire son nom d'une ville en Bavière qui a été le théâtre d'une bataille contre les autrichiens. L'histoire napoléonienne c'est possiblement horrible, mais pas "un bail de richous" pour autant.

This has been missing for a long time. I really hope @graphprotocol grants will help with the development of such tools. The combination of the newly launched network with clean, tested, audited subgraph will be game changing.

Now that @graphprotocol has launched, I wanted to share some tooling we've been working on @voteWithTally to power our subgraph infrastructure. Real-time monitoring and Continuous Integration for Subgraphs: critical for monitoring your mappings, essential for curators.

A thread about war profitiering onchain. 🧵 1/ Scammy smart contracts are nothing new, and they are not short of ideas to profit from the current situation. Right now, it is mostly about rebranding known hacks to make them appear like charity.

Note that contract using OZ's EIP712 will detect the chan id changing and are thus secure.

@florentderue C'est l'onde de choc que tu vois. L'air est comprimé à puis détendu à son passage. Ca se fait tellement vite qu'il n'y a pas de transfert thermique et que lq décompression provoque de la condensation. C'est le même phénomène que l'on peux voir lorsqu'un objet passe mach1

@danielvf This signature verification makes no sense. The msg.sender is already calling the contract in person, why would you require a signature on top of that? Signature are for when a third party calls a contract on behalf of someone else.
