@AaronCQL You are a gem 💎

Today marks my last day at Jupiter. I joined through the acquisition of Coinhall back in 2024, when the company only had 40 people. I leave with it at 150+. This is my honest attempt at putting into words what I've accomplished, why I chose to leave, and what I've learnt. --- Over the last 2 years, my role expanded from Head of Engineering overseeing 15 engineers to VP of Engineering with 40+ direct reports and 30+ more indirect ones, spanning various product, frontend, backend, data, and infra teams. The journey wasn't easy, and there was never a shortage of interesting problems to solve. Products and features Jupiter pushes out affect millions of users and literally billions of dollars. Here are some of the more interesting stuff: Ultra: a few months after joining Jupiter, I proposed the initial product and technical specs for what would become Ultra. Today it does $100M+ in daily swap volume and $2M-$5M in MRR. All while being built and maintained by a core engineering team of two. RTSE: in building Ultra, I also proposed, designed, and architected (what I believe) is Web3's first genuinely capable Real-Time Slippage Estimation for swaps. Prior to RTSE, users were failing 1 out of every 5 swaps. Now, only 1 out of every 50 fails - a literal 10x improvement in swap success rates. Jupiter Wallet: in June 2025, I wrote the very first commit for Jupiter Wallet. I was the only engineer on it for 6 months, shipping and maintaining it solo while managing 20+ engineers and other products. The first version went live in just 3 months. It now has 100K+ users with a 4.5-star rating, and was profitable almost immediately. The thing I'm proudest of though: in late 2024, @joedoe_ and I proposed turning jup.ag into a "Super App", with every Solana primitive under one roof. It was a very contrarian bet at the time, and was met with a huge amount of internal resistance. We pushed through anyway, and it's now the literal motto of the company: "Just Use Jupiter". --- So why did I choose to leave? As the company grew, I spent as much time on org design as on code. Scaling org structure past 100 people is as much politics as design, and I've honestly lost many of those fights. I wouldn't describe myself as a particularly good politician, nor do I enjoy politicking much at all. I've always viewed myself as an operator: in the trenches with the engineers, late-night debugging over the stupidest of bugs. In the past 6 months, however, my time was increasingly spent on being an "executive" and making higher-level decisions, and less on day-to-day operations. But this wasn't really the crux. There's a post by John Carmack detailing why he left Meta - I could have taken it word for word and it'd be reflective of my experience: "I have a voice at the highest levels here, so it feels like I should be able to move things, but I'm evidently not persuasive enough... I have never been able to kill stupid things before they cause damage, or set a direction and have a team actually stick to it. I think my influence at the margins has been positive, but it has never been a prime mover." --- I don't have any regrets though. In fact, I've learnt a great deal along the way. Here are some of them, in no particular order: 1. Having a team of 1x engineers, but who work cohesively together, is much better than a team of 10x engineers who are all opinionated and disagree with one another. 2. Judging one by their output is almost always better than judging one by what they say. 3. Putting the wrong people in the wrong places is far more damaging than not having them at all. 4. If you are a manager, learn to trust the people you manage and try your hardest not to break their trust in you - this is how you build a team that's loyal to you. --- I remain grateful that Jupiter took a bet on us back in 2024, giving the Coinhall team a much bigger arena to play in. Leaving the team that I've personally built over the last 5 years remains one of the hardest decisions I've made in my life. So, what next for me? I don't really have anything concrete thought out thus far. I plan to take a short break, touch some foreign grass, and come back to cook once I'm hungry again. But to the team I built, and the engineers I spent those late nights in the trenches with - thank you for putting your faith in me. You were the best part, and the part I'll never forget.

@yo_itsmatt @vibhu @FefeDemeny 🔥

You can call me the comeback kid Your move @FefeDemeny

Frontier is a banger so far: - 3500+ retail traders signed up - $100 million in volume on a single asset during our first trial campaign - Shipping trading distribution to 25 ecosystem teams - Hundreds of VIPs applied, representing trillions in potential annual trading volume that can be migrated to Solana

Wall Street closes. Solana doesn't. Open to the world, 24/7, straight through the weekend.

@drpeepee @datdsgnr Haven’t seen a merch drop this heavy in a bit 😭

wow it turns out people really like referral codes, up to 10% USDC cashback, and spending stablecoins from the best mobile wallet in the game. (and they don't even know what we're going to ship in April yet 🤭) there's no time like the present to get @JupGlobal

@mango_ @molusol @solana @Backpack @solflare @phantom @Titan_Exchange @JupiterExchange @kamino_swap Do you have a demo of what it looks like? Does it happen to you often? Shouldn’t be happening in any case

@molusol @solana @Backpack @solflare @phantom @Titan_Exchange @JupiterExchange @kamino_swap true, execution is way different from app to app JUP mobile gave me a weird rate of $10,000 > 0.4 SOL haha, probably a bug but I'm pretty sure it routes through jupiter engine anyways

Hope this settles the big debate: best-performing swap on @solana Mobile: 1. @Backpack: 114.69 SOL 2. @solflare: 113.74 SOL 3. @phantom: 113.72 SOL Web app: 1. @Titan_Exchange: 114.69 SOL 2. @JupiterExchange: 114.68 SOL 3. @kamino_swap: 114.10 SOL $10,000 USDC size, executed within 1 minute; slight price fluctuation may apply.

@TorvikArts @SolanaSensei @jup_mobile @solana @JupiterExchange @jup_portfolio @jup_studio @kashdhanda @weremeow @jup_dao @JUPANDJUICE @toly Thanks for the question, only reclaims SOL from your empty ATA. No burning taking place here!

@SolanaSensei @jup_mobile @solana @JupiterExchange @jup_portfolio @jup_studio @kashdhanda @weremeow @jup_dao @JUPANDJUICE @toly Does this "burn" the token? I checked and got scary to see active tokens in the list. The function just say that it closes the account, but I'm not sure if I'm going to lose any token. Sorry for my ignorance, but I want to confirm.

Reclaiming SOL got even easier now. You can now close SPL accounts to claim rent fees directly from @jup_mobile Update your app if you haven't and the pop up should appear on your homepage.
