It's always best to do calculations in high precision and without rounding using only the ring operations. Failing to understand the risks of breaking this rule is now pushing 10 figures of losses.
When you see calculations that are rounding up, there is a small chance that the rounding up is severely overstated, as it always at least returns 1 wei, even if the result would be like 0.0000001 wei.

These guys have been going over the @0xProject Settler codebase and making sure we've dotted all our i's and crossed all our t's. I think they're building some cool tech. Their team is hungry for success, and this is your chance to get some top-notch review for cheap.

ERC20 is really cool, but also really dangerous. To 10x the ERC20 ecosystem, we need powerful tools to produce human-readable descriptions of tokens behavior from deployed bytecode
Excited to be speaking at Crypto Hub Malta this October 8th! 🔐✨ I’ll be diving into Token Security Analysis with @dedaub — exploring how ERC-20 tokens evolve and the hidden risks in new deployments.

⚠️ Our white hat team, the @DonjonLedger, discovered a flaw in Tangem cards that makes brute force attacks possible. As always, the Donjon followed responsible disclosure to inform Tangem, user protection is our priority. We can now reveal our findings in full: 🧵👇

tok{In} is such a cool product. I've been using it since beta. As ERC20 grows, we need deeper analysis tools to be able to transact quickly and with confidence. ERC20 is a powerful and flexible abstraction, but that means that users need better tools to know what they're buying.

I can say with confidence that Bailsec is worth every penny. Their integrity and transparency is beyond reproach
Our quotes are always 100% exact and fair. We never try to overcharge our clients. But 6 months ago, we had 2 cases where our teams completed audits earlier than estimated. We informed the partners ourselves and sent partial refunds back, several thousand dollars each. They

I currently use Proton for email. I've been wanting to move it, but I don't have a good idea for where to move it to. Can somebody sell me a good alternative?

another problem is the sheer incompetence of governments. you'd expect the top-funded entities on the planet (via taxes) to keep up with the latest technologies, at the very least for taxes, because that's how they get most of their funding.
incredible that we have been working on a better financial infrastructure for the world for 15+ years straight, and we still can't move on from using fricking banks that charge a gazillion in fees for updating a database entry

This is the spirit of DeFi.

Last month, we turned down a $300k+ gig after being heavily underquoted by a “Tier 1” competitor. Our lead audit team estimated 30 days for one part of the scope, the competitor quoted 10 days! It seems the new norm is cutting corners (and quality) just to win deals at any

Come hear me make my point about scalability/decentralization dilemmas, the computational complexity class of DEX aggregation, developer goodwill, and desire paths.
2/5 🧵 Fusaka Two last-minute requests for PeerDAS: ▶️ @duncancmt points out that the block gas limit being set to 16.8M in PeerDAS is a breaking change for apps - can it be maintained at 30M? ▶️ @d_gusakov asks if the supernode threshold can change to accommodate CSM stakers

ERC20 is a powerful tool for communities to set their rules. If you're a token developer, check out what you can do with ERC20. If you're a DeFi developer, check out what you need to be aware of when handling foreign ERC20s

I know many changes look/feel inconsequential (who _really_ needs tens of millions of gas), but inevitably somebody depends on that behavior. When you break their dApp, you alienate them. Past perpetrators of this have been the whole EOF debacle and pruning logs in EIP-4444
