gm frens! Long time, no see 😉 You’ve been eagerly waiting and guessing, and the moment is finally here: We’re thrilled to finally announce EthCC[9]! This past edition was filled with excitement, a lot of heat and plenty of sweat. We had a chat with the sun and mutually decided that it would be best to shift our dates to a slightly cooler (but still gorgeous) time of the year ☀️ So, drumroll please, EthCC[9] will take place in Cannes from… 📅 March 30 to April 2, 2026! Mark your calendars, get ready and stay tuned for more info! 💙❤️🩵

The GLP pool of GMX V1 on Arbitrum has experienced an exploit. Approximately $40M in tokens has been transferred from the GLP pool to an unknown wallet. Security has always been a core priority for GMX, with the GMX smart contracts undergoing numerous audits from top security specialists. So, in this hands-on-deck moment, all core contributors are investigating how the manipulation occurred, and what vulnerability may have enabled it. Our security partners are also deeply involved, to ensure we gain a thorough understanding of the events that occurred and minimise any associated risks as quickly as possible. Our primary focus is on recovery and pinpointing the root cause of the issue. Actions taken: Trading on GMX V1, and the minting and redeeming of GLP, have been disabled on both Arbitrum and Avalanche to prevent any further attack vectors and protect users from additional negative impacts. Scope of the vulnerability: Please note that the exploit does not affect GMX V2, its markets, or liquidity pools, nor the GMX token itself. Based on the available information, the vulnerability is limited to GMX V1 and its GLP pool. As soon as we have more complete and validated information, a detailed incident report will follow.

As predicted everyone is fomo-ing in to @EthCC, and here’s why: - This will be the biggest EthCC by numbers to date! That’s major. - Cannes is beautiful how can you say no to the South of France in the summer - EthCC knows how to put on an impeccable event (the secret speakers are insane!) - The talks are always the highest quality (no panels, no firesides, just pure knowledge) - Cannes is built around security, if it’s safe for Tom Cruise, it’s safe for you (if you’re not doing stupid things you shouldn’t do in any city) I’m bullish. @aave and @LC are sponsoring the main @EthCC event, we’re also hosting a DeFi Summer Day, and a very different and special @raave. À Bientôt Les Amis! 🌴

Research shows that CoW Swap consistently offers the best prices among major DEX aggregators. Yet, other research shows that in batch auctions, a trader might not get the best solution for their trade. So how can both be true? Let's explain.

The @VenusProtocol incurred $902K in bad debt from an oracle manipulation attack that nobody saw coming... except everyone should have. Let's dive into how a well-documented ERC-4626 vulnerability continues to drain millions from DeFi protocols despite clear warning signs.

Ethereum Foundation Treasury Update The Ethereum Foundation (@ethereumfndn) has set up a new @safe 3-of-5 multisig wallet. The wallet address is 0x9fC3dc011b461664c835F2527fffb1169b3C213e An op has been initiated to send 50,000 ETH there, but be patient; due to signing delays, this will take a few days to process (etherscan.io/tx/0x6872c97c57…) The EF will use this new wallet to participate in the DeFi ecosystem. We've made a testing tx on @aave. Stay tuned! Also, @safe has proven safe and has a great user experience, and we will transfer more of our funds here over time! #helloworldcomputer

Why USD0++'s Depeg was Imminent I used to work on Morgan Stanley’s high-yield bond desk, so I’ve seen my fair share of distressed assets and quirky mechanisms. "High-yield" sounds fancy, but let’s call it what it is: trading the shittiest of shit bonds. Think defaults waiting to happen—the gutter trash of the credit world. What’s happening with USD0++ feels like déjà vu. Let me clarify: I’m not saying it’s trash—it’s collateralized by very safe assets, but let's say there are definitely some high-yield elements at play, along with a whole lot of tranching. As of writing, USD0++ is trading at $0.94, a 6% depeg from its supposed $1 peg on DEXes. Why? After the protocol's announcement of its “dual exit” option, hundreds of millions of USD0++ got dumped by DeFi traders, leaving its largest Curve pool wildly imbalanced. What is USD0 / USD0++? USD0 is a simple stablecoin. The real point of this entire game is to convert it to USD0++, the staked version. USD0++ is where the action happens because it earns you $USUAL tokens (we’ll get to those in a bit). But here’s the kicker: Holding USD0++ locks you in for four years—a detail many DeFi farmers glossed over. In essence, USD0++ functions as a zero-coupon bond—you lock up your money and earn nothing until the end of the term. If you expect 4% annually over four years, the fair value of USD0++ today should be around $0.855. This means you’d buy it at $0.855, hold it for four years, and redeem it at $1 for a risk-free 4% return. Before today’s announcement, you could redeem USD0++ 1:1. Now, that’s all changing. The Dual Exit Details for USD0++ Here’s how the new exit mechanisms work: 1. Conditional Exit: Redeem USD0++ at 1:1, but you forfeit part of your accrued yields. This “Early Unstaking” option launches next week - I'm guessing you'll need to burn $USUAL to exit. 2. Unconditional Exit: Redeem at a floor price, currently $0.87, which will gradually rise to $1 over four years. This option is for those who want to keep their upfront rewards. For those still HODLing their USD0++ There's a trade-off: 1. Choose the speculative strategy by staking USD0 to USD0++ to farm USUAL tokens and chase those headline-grabbing 60% yields. 2. Choose the Base Interest Guarantee option by locking up USD0++ for four years to earn the “real” risk-free yield of 4% annually, payable only at the end. But why lock up USD0++ for four years when you could buy liquid treasury-backed ETFs from BlackRock, exit anytime, with higher liquidity? DeFi users are farmers, and those shiny 60% yields are what they’re after. Option 1 was the only ‘real’ option—at least, until today’s announcement. The key takeaway: USD0++ is now being recalibrated to reflect its true nature and value: a zero-coupon bond plus a $USUAL token emission mechanism. But there are more layers to this. USUAL... USUALx... USUAL* Right now, the protocol keeps all the revenue from treasury bills, while participants are left with what looks like an ever-emitting token. There’s a fee-switch coming, though. Soon, 100% of the interest revenue from treasury bills will go to USUAL stakers, who will earn another token called USUALx (with a 10% fee for unstaking). It gets even more complicated: early investors receive a token called USUAL* (or USUAL Star), entitling them to 10% of all USUAL emissions and 33% of penalty fees. Lots of Moving Pieces Here’s how to read it: 1. USD0 Holders: surrendering your interest yield to use the stablecoin, effectively financing this game for the other counterparties—USD0++, USUAL holders, USUALx holders, and USUAL* holders. 2. USD0++ holders: surrendering your interest yield for 4 years, effectively financing this game by betting that $USUAL tokens emitted will be worth more than the interest yield. 3. USUAL / USUALx stakers: betting on the USUAL token to rise / capturing the interest yield surrendered by USD0 and USD0++ holders. 4. USUAL* holders: get 10% of all $USUAL emissions, as well as 33% of penalty fees, receiving a percentage of the value chain. Just my two gweis, and as always, DYOR
