On October 20, an exploiter took advantage of a vulnerability in a legacy function of Slice's settlement contract, taking about $41k in store earnings that hadn't yet been withdrawn. Most of these funds were Slice's or tied to past partner initiatives; fewer than 10 user stores were affected according to our initial review. Within an hour of being alerted, we paused the contracts and fixed the vulnerability. We also contacted incident response teams and traced the stolen funds, which we're actively monitoring. Funds in users' wallets were never at risk. Use of the Slice protocol is temporarily paused out of an abundance of caution while we complete our review. If your store was one of the few affected, you'll see a notice in your Slice dashboard with next steps. To the exploiter: return the funds by Friday, October 23, 17:00 UTC and keep 10% as a white-hat bounty, and we'll treat this as a white-hat recovery. After that, we will pursue all available options to recover them. To our users: sorry for the inconvenience, and thank you for your patience. We take security seriously and have already taken steps to prevent similar attacks, which we'll share more about soon. We expect Slice to be back up and running within 24 to 48 hours, and we'll keep you updated here until then.

We’ve spent six years building Slice on one bet: the future of commerce is open, and bigger than any one marketplace. Commerce is about to change dramatically. Merchants will have new ways to reach customers without convincing them to visit a website or depending on an intermediary to be discovered. The irony is that Amazon’s greatest strength—its tightly controlled platform—is also what makes it unfit to lead the next wave of commerce. That’s why decentralization is fundamental to Slice, and why Ethereum is instrumental to our vision. An open protocol lets independent merchants, applications, services, and marketplaces become part of something much bigger than Amazon could ever become on its own. It’s almost time to show the world what we’ve been building.
The next Amazon is an open protocol.

Amazon banning agents is the first opportunity I've seen since Amazon was founded for a startup to create an Amazon competitor. People will want agents to buy stuff for them. It will be one of the main use cases. And they won't want to use some Amazon-supplied agent to do it.

nice work on unlinkable payments! ties well with the work we're doing on erc8128 and @slice__so. more on this soon
Today the EF and OA announce zkAPI—a new means for private AI Picture this: deposit ether into a vault, sign a zk proof, get a fixed amount of private inference. Advances like these help us move past middlemen's requirements that we link our data and identities. Read more below

Base and Coinbase Wallet wouldn’t be where they are today without Chintan. A lot of the best and most impactful work across both has his fingerprints on it. I know because I’ve seen it firsthand. He’s one of the most exceptional leaders I’ve ever worked with: somehow everywhere at once, always a step ahead and on top of the details, while consistently bringing out the best in the people around him. From the very first Base Cafe and Based Merch stores, to the Onchain Summer Shop, to the countless Base + Slice events we worked on together over the years, I’ve only come away with more respect for him every time. What he probably doesn’t know is how much I learned just by watching him work over the years. His dedication, judgment, and especially the way he leads and gets the best out of his team. Chintan has had a much bigger impact on those around him than he probably realizes, and I’m very excited to see what he does next. He deserves every bit of the great things waiting for him.
Five years, a few bull markets, and 100's of IRL activations later, my Coinbase run is over. I came to crypto because the internet should move value the way it moves information: open, instant, and owned by the people using it. I came to Coinbase because of the people. I'm proud of what we built with @CoinbaseWallet and what it is today. Crypto apps were painful to use. Getting them in front of real people was the fastest way to figure out what sucked and fix it. It took building Base Cafe's around the world and onboarding thousands of merchants to start making USDC payments work. @brian_armstrong gave us the space to do things differently: tremendous agency, a long-term view, and no theater led to an unreasonable amount of shipping with joy. Forge and the AI work I did across Coinbase came from the same place: less stuff between an idea and getting it into someone's hands. I'm proud of the team and culture we built inside the Coinbase mothership and am fortunate to have led the most talented engineers, designers, and product people I've ever worked with. Right before the end, I got one last thing through: changing the name back to Coinbase Wallet. yw. Thank you to Brian and @emiliemc for the trust, and @jessepollak and @cobie for pushing what's possible. 🙇 to my ride-or-die Wallet OGs @shalinpei and @sid_coelho , @0xaneri and the whole team. You are all truly the best. To all the CT folks I met along the way: you're all way cooler in person and i'm lucky to have met so many of you. 💙 Time to build on a new frontier. 🫡

> A world computer should also be the main owner of its state. [...] Composability is the superpower of blockchains Exactly. Verifiable offchain computation is what lets Ethereum scale. Onchain state is what makes it composable. Ethereum's endgame is to hold the world's state. Slice applies this thesis to commerce, and doing it properly meant rebuilding commerce from scratch. I'll be going deep on this soon, but in a nutshell, when state moves onchain: - New primitives become possible, enabling more powerful, automated processes — on Slice we call this "smart commerce". - Many problems typical of web2 disappear. - New problems appear. DeFi showed what happens when one domain's state moves onchain. We're doing the same for commerce, and I expect the pattern to repeat across most domains over time. I believe one of Ethereum's main challenges is resolving the tension between privacy and composability. Ethereum wins when developers and users can decide what is private, shared or public, and everything stays composable. That's why I'm so excited about obfuscation. Most of the building blocks are in place, and the design space in commerce is immense. Truly grateful to everyone who has contributed and keeps contributing to Ethereum for making possible a future worth building toward.
This tweet is already bullish, and I want to add some nuance because the way I see it there is something even subtler and more awesome about it Yes, pushing computation “offchain” with the computation committed to and proven succinctly onchain is awesome because it saves a ton of work to the network and allows for super light nodes. That’s a cryptographic world bulletin board, but not quite a computer imo Indeed, a world computer should also be the main owner of its state. You can keep state offchain, meaning that contention resolves out of band from the ethereum network. This is not necessarily something we want however, because the state of ethereum, its liquidity, its accessibility, is a huge part of why ethereum enjoys such massive network effects. When a liquidation is meant to resolve, I don’t want it to resolve on Aave’s server, with a brittle API governing access to the pool’s state and its updates. I want the ability to learn the state of the pool by looking at the chain, and the ability to act upon that state unmediated by sending a transaction that I know will be included given ethereum’s peerless censorship-resistance and that I know will execute given ethereum’s 100% uptime. This still leaves room for a lot of presettlement infra stitching things together, but it’s much stronger than ethereum being a “simple” checkpoint for what’s happening outside of a limited view of the world state. Composability is the superpower of blockchains, and the more granular and accessible state is onchain, the more permissionless it becomes to compose and innovate. The vision of ethlabs as I’d put it is to have the best state for the L1 as liquidity hub and the most secure place to hold and mint assets from, with L2s spawning differentiated state neighbourhoods that both leverage and reinforce L1’s, bringing new users, more liquidity and growing the onchain economy by eating the offchain one. That’s what we mean when we say ethereum becoming the root of the global economy. For this we need scale, speed and security. We’ll be pushing hard on those!

the endgame is portable accounts that can authenticate and authorize payments across apps and devices. that solves the same problem across industries. no need to turn a game controller into a payment terminal. it's time to upgrade the web's identity layer.

and for that, new web authn/z standards are needed. like ERC-8128 erc8128.org
My agents should be able to do anything I can on a computer or a phone ( and I should be held accountable for their behavior).

No one should have to hand over their passport just to be able to pay. You’ll never have to KYC to buy on Slice.
‼️ BREAKING: Revolut handed over customers’ passport copies, verification selfies and full transaction histories to a malicious actor. The actor sent lawful government information-demand emails using a genuine government domain that passed domain authentication. Revolut later concluded they were not authentic. Affected customers were notified on Friday. What may have been disclosed ranges from name, date of birth and home address to account statements, withdrawal records and complete Bitcoin transaction history. The company says it has alerted the agency to the unauthorised mailbox on its domain, blocked the address and begun notifying regulators. It has not named the agency, explained how someone obtained a mailbox there, or given a number of affected customers. ZachXBT, who circulated the notices, believes the incident was limited in size and aimed at high-net-worth users.

commerce needs new rails and primitives if we want agentic commerce to reach its full potential without becoming a security nightmare. good news is we’re building them at @slice__so, and we're almost done.
