Any workflow. Every chain. Hours not years.

Proud to partner with @megaeth! Together, we’re making it easier than ever to get started. Simple, seamless funding from day one.

@lyronctk @paulg was always right. Build something customers want.

Crazy that crypto used to be a place where following YC advice made you no money But market distortions never last. The YC playbook always wins in the end Good to be back in the land of talking to users, doing things that don't scale, and building something people want

Some of the best advice I got early on (from @ilmoi at @alliance HQ): “You only need to talk to a surprisingly small number of the right people to build something lots of people love”

Huge congrats to the @SurfAI team! Have used the product personally and can attest to it being awesome. AI + crypto deep research!!

@cdixon @guywuolletjr Awesome news! Congratulations @guywuolletjr!!

Today we are excited to announce that we are promoting Guy Wuollet (@guywuolletjr) to General Partner. We first met Guy in 2018 while he was studying computer science at Stanford, where he also rowed varsity crew. He initially joined the firm as an intern working on the enterprise go-to-market team, but it soon became clear he was most passionate about crypto. We kept running into Guy: first when he joined our Crypto Startup Accelerator to build a decentralized ISP, then while doing research at Protocol Labs, and finally as a teaching assistant for our research partner @danboneh. After joining us full-time in 2020, Guy began investing in infrastructure, DeFi, and DePIN. He has been a steady and creative force, making significant contributions to more than 20 investments, including Solana, LayerZero, Gensyn, EigenLayer, Daylight, and Morpho. Based on insights from prior investments like Orchid, Nym, and Helium, Guy defined our thesis on what would become known as DePIN. He wrote one of the defining blogs on why DePIN matters and helped us invest in Gensyn. Next he wrote about decentralized energy and led our investment in Daylight. Guy also invested in decentralized transportation, robotics, and AI projects as he helped run our accelerator. DeFi has always been central to Guy’s thesis, but his early investment in Morpho was driven above all by conviction in the founders. He recognized in @PaulFrambot and his team a rare combination of technical depth and clarity of vision. Since then, Morpho has grown to billions in total value locked and become one of the leading protocols in DeFi. Their V2 launch marked a major leap forward in efficiency and scale for on-chain lending. Through his work with founders, Guy has shown a rare mix of deep technical expertise and thoughtful pragmatism. Founders often tell me how impressed they are that Guy systematically reads, understands, and provides useful feedback on protocol design and other hard technical topics. His writing and advice on token and protocol design have helped influence many projects in our portfolio. Beyond his investing skills, Guy has been a calm and positive presence, with a wry sense of humor, both inside the firm and for founders. As the crypto team grew from a small group to more than 80 people, he helped recruit and mentor many of the talented investors, researchers, and operators who make the team what it is today. Guy is an invaluable member of the team, and it has been great to see him grow and develop over the last five years. Guy joins me, @alive_eth, and @AriannaSimpson as @a16zcrypto’s fourth General Partner.

New crypto category unlocked: unified deposits. Thrilled to bring Halliday's all-in-one API to TRON. Halliday offers developers: - Global on-ramp network - Centralized exchange connector - Cross-chain swap router Grow your revenue today!

@0xDrewF @rynesaxe @gakonst We actually built this at @HallidayHQ. Will DM you both.

@rynesaxe @gakonst Even without control flow, something that lets you slice returndata and splice it into the next call would be super useful.

What are the coolest smart contracts that you wish somebody would build? It's OK if somebody did it before, maybe apply a spin on it.

@helenaeverley @HallidayHQ 🫡 more to come soon!

@HallidayHQ I would use this. Had the most difficult time buying some tokens on BNB this weekend

Crypto payments today: fuzzy, confusing and complex. We're changing that.

@FrankieIsLost @HallidayHQ is a novel approach. Just pay

what’s the best onramp option today? seems insane that crypto app builders have to eat 50%+ top-of-funnel drop off because users just can’t get funds into their wallets.

@gakonst The race in this vertical is like GPUs in the 90s. R&D, detail, and product excellence is the only way to win. This part of crypto will also be an endurance game.

Reminder that this is the most important product that's missing in crypto, there's some contenders for it, but no clear winner yet.

@gakonst @HallidayHQ

GUYS! SOMEONE?

@0xNairolf I’d tell them to “just pay” with @HallidayHQ

how would you onboard someone to crypto? what do you show/explain first?

@MrStasStas @HallidayHQ This depends on your geolocation. For most jurisdictions you'll see the following:

@HallidayHQ 8$ fee?

Markets won’t just digitize—they’ll compute. Blockchains unlock computational capital. The surprises lie ahead.

Let’s turn money into a developer platform. Crypto.

Beyond thrilled to bring Halliday Payments to @StoryProtocol! Crypto checkout in one click is here: - Global on/off ramp coverage - Centralized exchange connectivity - Intelligent cross-chain routing This is not 3 products. This is one product. Just pay.

@devrelius @HallidayHQ @StoryProtocol 🫡 thank you sir!

@HallidayHQ @StoryProtocol Halliday is such a godsend

Onramp. Integrate. Check out. All in one flow. Halliday Payments is officially live on @StoryProtocol Learn how it's simplifying onboarding 👇

@helpdotfun @RaydiumProtocol Cool and novel idea! 💡

@AlanaDLevin I think this will happen and result in a positive outcome. High-level abstractions and orchestration primitives will reduce the complexity, similar to how virtualization abstracted machine management. @HallidayHQ is trying to accomplish this with the Workflow Protocol.

It's 2030 You're a merchant receiving payment from a customer. They pay with USDC on CircleChain but your payment termainl only receives StripeUSD on StripeChain. But once you get StripeUSD, you want to transfer it to your account with Bank of America, so you need to transfer it to BofAUSD on BofAChain. But wait, you go and pay your supplier. The problem is, they custody with JPMorgan. So then you need to get your BofAUSD on BofAChain to JPMorganUSD on JPMorganChain. But JPMorganChain is permissioned, so you need to route it through a special intermediary... and so on Is this the future we're headed toward?

@ycombinator @aaronchewbani @kavandoc Very cool and useful!

Synthetic Society tests your product with AI-powered user simulations. Their agents mimic real users to catch bugs, bad UX, and edge cases. Ship faster, kill manual testing, and build with confidence. ycombinator.com/launches/O7g-s… Congrats on the launch, @aaronchewbani and @kavandoc!
