passkeys in current form are a failed experiment — my advice is to avoid making passkeys a required/core workflow of your crypto wallet/application.

Some thoughts on modern text editor implementations: We've come a long way w/r/t text editing in computer science. Editing strings is actually an extremely complex problem when you factor in modern requirements such as distributed systems, realtime collab, performance, etc.

"yeah, i've authored an ERC" the ERC:

tRPC is the most impactful library i've added to my stack this year, by several orders of magnitude (@trpcio)

🤔

any frontend devs available for a 1-2 month contract? have a rare opportunity with an elite nft project that will be launching soon. this will be worth your time! react and typescript experience preferred. no crypto experience required. dm me!

most wallet infra falls very short for serious crypto product developers...between shoehorning passkey slop and half-baked permissions, clearly some product people are asleep at the wheel

Solidity code looks pretty fresh (as recent as ~2days ago). Are there plans for an audit?

passkeys are peak engineering performance art -- impressive demos, painful in practice. if you're shipping real products in 2025, think twice.

one second order effect about $SOL pumping is that a lot of the dev teams working on Solana took their grants in $SOL tokens early on and are now way up (some >10x!). extends runway significantly which allows room to scale/find PMF/experiment freely! wouldn't bet against it

🚨 0x v4 is now the cheapest way to swap NFTs on ethereum/evm-compatible chains, by a lot. 🚨

@matchaxyz trading over $1B of volume for the week no downtime, no additional fees, positive slippage always goes back to you, best prices.

matcha reflection thread 🍵: i joined 0x in the dead of crypto winter in late 2019. 0x api was released soon thereafter and averaging ~$2MM/month in volume. we knew that building a flagship DEX on top of 0x API in-house was key to controlling our own destiny. 1/n

it’s hard to recommend solana for critical infrastructure/tasks when it lacks a robust fee market

some alpha for those willing to pick it up -- if you want to level up as a wallet infra provider: 1. prioritize (zk) login via oauth. google login is the highest performing, highest satisfaction identity solution in crypto by orders of magnitude. sui did this very well, everyone can learn from them. 2. widen your permission set (mm delegation framework figured this out already, its embarrassing how far behind everyone else is). if a wallet doesn't have a good permission set it's a non-starter -- embedded wallets are much workable alternative in current form (also partially why 'subaccounts' aren't gaining traction either) 3. stop shilling passkeys, it's hard to take anyone seriously that thinks that's what's holding us back. shows a lack of experience supporting production-grade consumer-facing products with a large amount of users. it's a nice-to-have on top of your eg google identity. 4. start dogfooding more -- build MVP products on top of your solutions to discover the invisible walls and constraints you didn't think about (there are many) to avoid future developer churn -- switching costs are extremely low in this industry. 5. listen more -- _zero_ of my most experience product developer friends have been surveyed, interviewed or asked about feature sets from these new solutions. feedback goes into the void.

'onchain' only permissions (current direction of erc7715 implementation i'm seeing) are practically useless -- please speak with your users more

👀 @0xProject

sneak peak 🤗🔜

We've opened a frontend dev position on my team (@matchaxyz). I have never been so excited to post a job opening. If you're a frontend developer considering a change, I can't recommend this position enough. boards.greenhouse.io/0x/jobs… 🧵 Thread: Here's why I'm hyped 👇 1/n

(long form post soon, I am a recovering passkey maxi…)

one stop shop for liquidity. extremely excited to share this with the community.

wow @gridplus Lattice1 + @0xFrame is the best crypto wallet setup i've ever used. would recommend 10/10

i feel like this is a subtweet? hand-waving design in a highly technical domain is easy and lazy. when i talk to real users in support channels and user testing, it paints a completely different picture. design has major consequences for products -- to think otherwise is silly.

Just finalized paperwork on a 30yr mortgage loan at a 2.5% interest rate 🤯🤯🤯

new niche: let me angel invest in your round and i'll help you with your frontend code

effectively abandoned — respectfully, not sure why anyone would use thegraph at this point

had my first real vacation in two years(!); didn't realize how much i needed that. remember to take time to actually disconnect. now time to build

v excited for the NFT indexer i'm writing for @usetrader. will be open source and have a public API for the community. aggregates on-chain and off-chain data including sale history, pricing, minting, metadata, etc.

built using @usetrader nft swap sdk 🤝 if you're looking to build p2p swap in your dapp or build out an nft marketplace, this is the best library out there: github.com/trader-xyz/nft-sw…

you tell me

🤗 the @matchaxyz frontend eng team doubled in size this week (from 1 to 2 people!) super hyped for @dave4506 to join the team 🍵 we're still hiring! come join our close-knit team and do the best work of your career! boards.greenhouse.io/0x/jobs…

There's well over 30+ years of research and white papers just on efficient data structures for string manipulation. From gap buffers (en.wikipedia.org/wiki/Gap_bu…) to splay trees (en.wikipedia.org/wiki/Splay_…) to ropes (en.wikipedia.org/wiki/Rope_(…), it's still a very active area of research.

hire a large team and throw engineers at the problem? 🚫 no, the matcha team has had only 2️⃣ engineers (until last month, now we're 4️⃣!)... 5/n

me talking to claude rn piped.video/Q-aXOrAp_zA

spent a week+ fully offline from crypto (no charts, no code), can't remember the last time i did that....would recommend, didn't realize how impactful/refreshing that'd be. to all my builders out there, remember to take meaningful breaks!

most claude code problems boil down to 'skill issue' tbh

Monorepos have been extremely advantageous for the frontends I have worked on. I don't think the answer is as black and white as 'please don't'.

🚨 frontend gitcoin bounty alert: gitcoin.co/issue/0xProject/w… 🚨 we'll pay you to refactor the @0xProject marketing site to use web3-react. the site is well-organized and 100% open source. Bounty is 5000 ZRX (~$2000 USD) at the time of posting.

me pitching vcs a new way to defi

been cooking up some crazy mobile PWA experiences; haven't had this much fun in crypto in a long time

this is the most fun i've had building a product and brand in a long time. you're going to love it.

tl;dr i'm excited for 0x labs series a, and for the entire defi ecosystem leveling up. matcha has a unique feature-packed roadmap that'll continue to differentiate matcha from other DEX aggregators. stay tuned and thanks for being a part of the journey. still a long way to go! 🙏

some more info: - absolute world-class gigabrain team - innovative nft mechanics - top tier product, design, etc - we like the art - moonlighting is fine (it's okay if you have a day job!)

p cool to see matcha hit 100MM in volume. standing on the shoulders of giants, for sure. we're just getting started: lots of first-of-kind features and sustainable incentives soon to be released that will become industry standards. stay tuned!

using nextjs is a competitive advantage at this point

$ yarn list --depth 0 | wc -l average dapp has >1k dependencies installed. such a large surface area for malicious activity. many npm module publishers don't even have 2FA turned on. 🤔

embedded app wallets are here to stay (they test extremely well with beginner-mid level user cohorts, arcade wallet thesis, etc). missing ingredient rn is just frictionless cc onramping, e.g. apple pay $5 onto base and immediately begin playing

weird to see people praising this

successful next-gen crypto defi apps will also feel like gaming platforms. leaderboards, leverage, game never closes unlike RH, fun polished ux, ease of use -- it's coming sooner than most think.

if you're in denver, drop by for happy hour 6-10pm tonight. i'll be DJing Grid Collaborative Workspace

Listing day! My GF and I buy, reno, and rent homes in South Florida. Here's our latest project (w/ before & afters) we just finished and are ready to lease up! Took about 3 months, tons of renovations, super happy with how it came out.

the next innovation in DEX aggregation: - 💫 single-source swaps are now as cheap (if not cheaper) than the source, thanks to some amazing engineering efforts - ✨multi-source swaps are more efficient with 0x API than anywhere else

hey @AudiusProject do you have a playlist from #0xpo? music was dope

always doing the right thing: matcha team does whatever we need to make sure we're fighting for our users. we return any positive slippage to the user unlike competitors💰, charge no fees, etc. i spend most of my day thinking about how to improve the experience for our users 11/n

in our first public month, matcha did ~$69MM in volume. nice. since then, we've seen parabolic growth every month, month over month. last month we ended with over $1.2B in volume 💸. DAU/MAUs are increasing and sticky 📈. growth has been incredible to watch. how'd we do it? 4/n

would love some help user testing! 🙏 some very cool stuff we're cooking up 🧑‍🔬

jamming on some dapp code, listening to techno, $ETH and $BTC ripping. big 2017 vibes.

I expect to see CRDT-based data structures as primitive-level building blocks for next-gen 'collaborative-first' applications (see Automerge [github.com/automerge/automer…] for an example).

redpilling every engineer i come in contact with to learn solidity and build web3 stuff on weekends. it is working.

so...how'd we do it (imo)? - 🏃🏻‍♂️shipping fast - ⏱️ timing - ✍️ listening to our users - ⭐ always doing the right thing 7/n

so a few of us got to work designing and building out what would soon become matcha. we ideated on brand, came up with a lot of names 📝, and ultimately settled on 'matcha'. it had an available domain name and emoji ✅, and set the right vibe for what we wanted. 🍵 2/n

my dream start up to run: a commercial real estate development firm specializing in helping newly-minted crypto millionaires park gains in tax-efficient qualified opportunity funds.

if you've been building in defi and have yet to see hockey stick growth 🏒, keep at it. if you're just starting to build, keep at it. if you haven't started to build, there's no better time to start. we're still very early. i hope this serves as some inspiration! 🚀 13/n

sheeesh, this squad 🔥

Rendering: WebGL as a text rendering platform. A recent trend I'm seeing is bypassing expensive DOM (re)calculations and rendering the text directly to a canvas to support low-level optimizations. Sub 16ms rendering time should not just be a lofty dream, but a real end goal.

working on a good&fast open-source nft indexer; gonna be done soon, would love your input!

spent 8 hours perfecting a microinteraction animation. love the result. gotta put in the work to get the experience your users deserve.

It’s a canon event for any sufficiently complex web application

it's hard to overstate how much opportunity there is in defi right now. pretty much every team is hiring. dm me if you're looking to work in crypto and i'll help you find a good fit!

NFT orders on-chain? off-chain? the choice is yours with 0x v4

In all, I think we'll see more and more experiments around collaborative experiences and rich-text editing. Text editors are an extremely interesting problem space, balancing academic research and real-world constraints, while optimizing user experience.

one of the easiest ways for frontend devs to significantly level up their webapp animations is by using springs as opposed to duration (e.g. '400ms') or curves ('ease-in-out')

i'm humbled by the growth in this space. every day i wake up excited to make matcha better, and am very appreciative users trust matcha when there are many DEXs & aggregators to choose from. this isn't a victory lap, i'm getting right back to work after writing this thread 12/n

listening to our users: we held user interviews, ux studies, product studies 🧑‍🔬 to understand what was missing in the marketplace: an easy to use, user-friendly DEX with a welcoming and trustworthy brand with the best prices around. this allowed us to build the Right Thing™️. 9/n

huge marketing budget? also, no 🙅‍♂️. we spend orders of magnitude less than competitors' marketing budgets. we sponsor some podcasts 🎙️ and newsletters 📰 that we enjoy, every now and then. tbh most inbound referrals are organic... 6/n

plugin-based system with extensible strategies for classifying and parsing metadata. timescaledb for blazing fast time-based data queries. core written in typescript to ensure max accessibility for contributors. well tested.

we shipped an MVP in under 3 months 🏎️💨 and went from there. we did a very quick family&friends private beta 👪 to iron out any issues and quickly opened it up to the public after getting positive feedback 3/n

Every year, all software engineers should be required to spend at least a week on the customer support team.

shipping fast & timing: waiting to perfect your app means you'll miss important & serendipitous tailwinds. we launched publicly right as defi summer 🧑‍🌾 picked up. with ecosystem usage picking up, we were able lean in and absorb market share on the way up and hold on to it 8/n

Fast forward to 2018. Ropes have been proven out to be extremely functional, performant, and flexible in real-world text editing conditions. See Xi editor (started internally at Google) for real-world rope implementations (xi-editor.io/xi-editor/docs/…)

listening pt 2 anecdote: at one point, our users told us we were too expensive for single source fills (they'd just go to uniswap 😮), so 0x listened and made uniswap fills cheaper (or at-cost) to fill on matcha vs uniswap ✅ (source: blog.0xproject.com/a-compreh…) 10/n

great secondary form of auth, though!

what unique primitives exist in the solana ecosystem? (not trolling, i'm looking for things i can't do in the ethereum ecosystem)

back in miami from sf. mood is better, more productive, air quality is great, businesses are open, getting outside more, golfing and beach activities planned out. would recommend.

i just wanna know what @fabioberger123 is cooking up 👀👀👀

> less slippage than the playground slide at recess.

- gas-efficient off-chain orders (free to create orders, only costs gas to fill!) - swap any token combinations (ERC20/721/1155) - simple API surface area, no deep protocol knowledge required - free hosted infrastructure (orderbook persistance) - smol bundle size - multichain

@matchaxyz on @rainbowdotme via @WalletConnect 😃 if you haven't seen, it's now generally cheaper (or at cost) to swap on uniswap via matcha than uniswap's frontend: blog.0xproject.com/a-compreh…

🤝

Realtime collaboration: Operational transform (OT) was a good start in the early 2000's. Due to OT's inherent architecture, I think there's a local maximum in OT applications. CRDTs, while relatively new, seem to be where everything is headed (both research and industry).

ai grift starting to clear, agents quickly reaching local maximums on functionality -- those that are building next-gen underlying tooling for agents will be rewarded (@glider__-coded tweet)

must read if you're into the DEX space!

BREAKING: 0X LABS IS RUMORED TO BE CRUSHING IT 💪

2017 top vibes. never bet against the fast food contra-indicator fortune.com/2018/01/12/kfc-b…

i want to make it as easy as possible for developers to build data-rich apps around NFTs by providing an off-the-shelf service. some useful examples: what nfts an address has; floor price over time; rarity api; streaming API for nft sales.
