some takeaways from binance and the last few weeks of cyber apocalypse: - we’ve been building in crypto for the last 5 years and it always felt like we were at war, but now we’re definitely at war - don't think i've seen the industry coordinate like this before, swift action, no hesitation, united front - we’ve come a long way - for as long as I can remember the usual response to something like this used to be “just self-custody,” I think we're past the point where that alone is a useful answer - I do believe however that self-custody without single points of failure is the way to go in a world where everything feels more fragile, both in and outside of crypto - for personal custody, a 2/3 multisig with 3 different hardware wallet providers is a good start - for teams and enterprises, the list is longer and nuance is king, at a minimum: dedicated signing devices, diversified signers, alternative frontends for verification, alerts and monitoring - while we have AI to “blame” for pointing out the fragility and gaps in our systems, I do believe it will also be responsible for generalizing formal verification by making it cheap and accessible across the board - all the recent events absolutely don’t help me sleep better, but from a squads perspective we’re staying the course: formally verifying our code (now beyond onchain), always be fuzzing/pointing new models at our programs, obsessing over enterprise security, helping solana teams design their multisig setups and preparing for quantum - leading up to Breakpoint and after we’re going to be rolling out a couple major updates to the multisig experience as well as shipping more open source tools for the ecosystem - my DMs are open if you’re rethinking your custody setup, and reach out to STRIDE to get your opsec audited - our character development arc as an industry continues and the only way out is through ps: squads was not affected by the binance incident and all systems remain operational

If you believe that the world will be onchain, then you believe Brazil will be onchain And if you believe all that… you believe in Nora. 🇧🇷 Thanks @islanddao and @SuperteamBR for all the support 🤝

Bom dia, Passando pra lembrar que a Binance foi roubada em $6B, mas o golpe do Vorcaro chega a $10B. Ainda estamos em primeiro, segue o líder! 😎

Em pleno 2026 Outubro Cara chega como lead perguntando se tem reporte Sim, tem E se você está usando alguma solução mágica que promete o não reporte, eu tomaria cuidado (até porque isso não existe)

O Partido dele elege maioria pro Senado. O Partido dele elege a maioria dos Governadores. O irmão dele se elege Senador. A madrasta dele se elege Senadora. O Partido dele movimenta o maior fundo eleitoral do país. Um ministro indicado pelo pai dele conduz a eleição no Brasil. O que faz ele: Vai pedir asilo nos EUA alegando que temos uma ditadura no Brasil.

Poupar sozinho não dura. Em grupo, um puxa o outro: cada depósito chama o próximo e, se alguém esquecer, dá um toque. 🛟

SafePool makes saving simple by letting you pay with Pix, keep everything in reais, set the rules with your friends, nudge whoever is about to miss a deposit and get everything back when the group ends. Next we’re planning rewards and more structured groups so people feel even more compelled to save. Powered by @norafinancexyz and @hodle_app xitter.gq/safepoolapp/status/211…

I wanted to test if a Solana program with no source available could be pulled from the chain and reverse engineered into a byte identical open source version So I took the daosfun contract and did just that Found a critical security vulnerability in the mainnet program too, oops! All smart contracts can be perfectly reverse engineered now There is no security by obscurity anymore github.com/lalalune/daosfun-…

I've said it before and I'll keep saying it. Do not use Pinocchio. "I'm super smart, doesn't apply to me!" No, that's just hubris. If you absolutely need low CUs, use Quasar or Anchor v2 Using Pinocchio is like building a car from scratch to get to the park across the street.
(almost) Every single Pinocchio program I've audited had a critical. Pinocchio isn't the problem. Here's the pattern behind those bugs:

Today marks my last day at @ZephyrCloudIO. What an awesome ride! I've been building developer tools, AI harnesses, Stripe billing, bundler plugins, edge runtime on CF Workers and much more, in both TypeScript and Rust. If your team is building in this space, I'd love to chat!

Eu escrevia código de qualidade. Hj eu no maximo evito catastrofes
Por que tenho a impressão que sempre que alguém critica código de IA tá junto comunicando que código por humano é bem feito? Código de humano é uma MERDA inclusive o meu quando o tempo é CURTO. Pouquíssimas pessoas podem dizer que escrevem um código ÓTIMO ou to ficando MALUCO?

Not everything should be public. That's how it all started, and where it's going. Thanks @SuperteamBR for believing in us from day one. 🇧🇷
