I tried a few courses but they don't train the brain for auditing really as its more about practice and intuition than theoretical knowledge. For me the best way to progress is to try to audit real contracts and read reports later like previous contests etc. For beginners small contracts with simple logic. Often there are easy non critical bugs to be found.

What are the best classes about solidity security out there? I am looking for something which should take around 2-4 weeks to significantly increase someone skills (both in writing & finding bugs) in solidity contracts.

In this letter, the CEO of Coinbase talks about non-technical teams shipping production code. Honestly, I don’t think he knows what he’s talking about. Using AI agents makes it possible for teams who are not deeply technical in the syntax of a language to ship production code. But that team had better be very deeply technical in managing the structure and quality of the code that is produced. What the agents give us is the ability to disengage from deep syntax. But they do not give us the ability to disengage from modular design and architecture. You still need to be deeply technical in those topics in order to produce good production quality code.
Brian Armstrong@brian_armstrong

This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future. Why now Two forces are converging at the same time. We need to be front footed to respond to both. First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth. Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day. All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core. What this means To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice? - Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles. - No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams. - AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role. In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs. To those who are affected I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done. All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information. To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements. Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters. How we move forward To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together: Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it. The Coinbase that emerges from this will be more capable than ever to achieve our mission. Brian

I like blockchain tech quite a bit because it extends open source to open source+state, a genuine/exciting innovation in computing paradigms. I'm just sad and struggle to get over it coming packaged with so much braindead bs (get rich quick pumps/dumps/scams/spams/memes etc.). Ew

My EthCC 9 Recap Probably the best one yet. Attendance down, conversation quality massively up. Perfect weather (late March > July heats) and Cannes city layout allowing you to hop between meetings and events at lightspeed. Conversations about all things vaults dominated the floors. Access control, transparency, risk management. Sure, more Patagonia jackets, but a clear sign of the space maturing. The conversations confirmed that Spectra's value proposition aligns with what the market is looking for right now, with yield tokenization and streamlined liquidity access increasingly in demand. Productive meetings with teams including @monad @OpenCover @GamiLabs @kpk_io @Rockaway_X @LiquityProtocol @FlareNetworks @schuman_io @StellarOrg and more. We shared early details of a major MetaVault integration with select partners. The reception was strong, and we're looking forward to making it public soon. Spectra limit orders remain one of the frequently requested features from the teams we spoke with. More on the state of the order book is in my latest Q1 2026 post. After all these years (never missed a single EthCC), I'm still meeting people for the first time that we've already been working with. The demand feels concrete: organic interest in yield infrastructure, real revenue-generation conversations, and growing attention toward wallet-level distribution. On Spectra's side, we're in early discussions around integrations that could significantly expand how users access the protocol. More on this when we're ready. Events like @Vault__Summit were packed. Cannes delivered.

STRK at $0.034 with #1 developer activity among all L2s. down 64% YTD. the market is pricing in exactly zero value for being the only production L2 running hash-based proofs instead of elliptic curve SNARKs. quantum-resistant wallets already live on mainnet since march. strkBTC and STRK20 privacy standard both launching end of april. 6.9m BTC sitting in addresses with exposed public keys that Shor's algorithm eventually cracks. every other ZK rollup will need a full rearchitecture to get quantum safe. starknet already shipped it. dev activity says the builders know. price says the market doesn't care yet. that's the asymmetry.

USDC MetaVault curated by @GamiLabs is worth watching. Two months in, the share price grew from 1.0024 to 1.0166, translating to ~8.4% annualized USDC base rate. With rewards and points on top, the rate now hovers around 17%. How MetaVaults work and why they matter ↓

Join me (02/04, Redford, 10h45) if you're curious about the different flavours of clear signing and if they make good CROPS, how 7730 sausages are made, or what happens when you pay Jean Claude to make a hardware signer but forget to ask for no mistakes ethcc.io/ethcc-9/agenda…
EthCC - Ethereum Community Conference@EthCC

Hardware wallet fragmentation across different Ethereum applications creates friction for users, and btchip (@btchip) is tackling this challenge head-on in the Security track. A seamless signing experience could be the key to making self-custody feel as simple as using any other app.

I thought i was leveraging skills well but turns out i there us much more we can do. Here are my fav advices shared by Claude engineers: - Skills can be much more complex structures than just md files. Make folders with examples, templates and boilerplate functions to help claude focus on the right tasks. - Improve skills with Gotchas, on the fly add things Claude doesn't get right. - This one takes experience but avoid suffocating Claude with information, he needs freedom to maneuver well but at the same time some guardrails help him focus on the right stuff. - The skill description is a trigger for the model, not a summary or context. - Cool examples of skills like /freeze and /careful let you constrain Claude only when it matters - Don't over complexify the skill to extend its reach. Better to have multiple specialized skills that interact than one swiss knife.

Great transparency by the CoW team and technical details. Most important thing to improve now is the robustness of the solver competitions. Some elements like the gas limit were obviously a mistake but as a whole the backbone of the protocol is the auction system and it didn't perform well. Aave should also propose different provider routes for more competitiveness and decentralization.
