Day 23 of building a trading app we never had - Invite codes cut your fees. Your first fee is free on up to $500 of that trade (Solana), then every fee is 10% off on every chain. It comes out of the burn, so your solana:6FhVPctYg363pQbs4iSvqyHe2cJzfsvFD96gePy6pump back and your inviter’s share don’t change. Live now. - See who can sell into you. The terminal opens each coin on it: “8 holders are in profit at this price · hold 37.3% ≈ $372.8K”, counted the same way as in the app. The same line sits under the Buy button. Live now. - Fewer failed quotes. A lagging Solana node failed 26 to 52 quotes a day through no fault of yours. Since yesterday’s fix at 16:45 UTC, none has. Live now. - Robinhood Chain coins buy from the real pool. Relay was routing CTRL through a $0.51 pool and refusing $100+ buys at −99.9%. It now compares providers on every Robinhood Chain, Base and BNB Chain quote, and CTRL quotes −3% to −6%. Live now. - Wallet maps last all day. The daily budget used to run out by mid-morning; now each hour gets its share. New maps resume at 00:00 UTC tomorrow. Live now. - Swipe, no Next. With the arena on, swipe up and down to change coins; the Next button is gone, since people swiped twice as often as they tapped it. Arena off keeps Next. Live now, on 286. - Anyone can ask in Takes. Non-holders can post questions, marked “no bag”. Ties go to holders’ votes, so empty wallets can’t upvote spam to the top, and posts without a bag are limited to 2 an hour. - Post your win. After a profitable sale, share your card with one line and a link to the coin: “Closed $BONK at +$42.10 (+81.0%) on Exfil.”

Funny enough, I've onboarded a few IRL buddies into crypto through @exfildotfun and they absolutely love it. 😂 Instead of staring at candlesticks, they're watching rats around a 3D arena, exploring wallets and learning how trading works. They keep coming back just to watch their rats. 🐀 Honestly, @abhilashi might be onto something here. Maybe the best way to onboard normies isn't more complicated charts. It's making crypto fun and easier to understand. ☝🏽Secure your spot to get lower trading fees when you join EXFIL early.

Day 22 of building an immersive trading app we never had tl;dr: mobile is stress tested and looking stable now (we will take bigger swings from here) - Cross-chain trades confirm in seconds. Relay's trade history ran 8 to 13 minutes behind yesterday, and Exfil waited for it. Every Robinhood Chain buy sat on "Confirm delivery" for minutes, and an Extract that needed gas failed, because Add gas gives up after 30 seconds. Now, once Relay says a trade succeeded, Exfil confirms it from the chain itself: the coin landing in your wallet for Robinhood Chain, Base and BNB Chain buys, the USDC arriving for sells to Solana, and the ETH or BNB arriving for gas top-ups, smart wallets included. On 12 real Robinhood Chain buys, the chain's amount matched Relay's every time. If the chain can't be read yet, Relay's history still decides. Gas costs and fees on these trades fill in once that history catches up. Live now. - About works on every chain. In 1.1.38, the About tab on Base, BNB Chain and Robinhood Chain coins couldn't load its links. Fixed on the server, no update needed. Live now. - Bag Lords counts the biggest bags. One bag over 1% of its pool, a pool under $10K or a coin quiet for 15 minutes took the whole wallet off Bag Lords and Up Only. The biggest open profits (+$35K, +$17K, +$9K) were missing and the podium topped out near $500. Now a bag up to 1% of its pool counts at market price. A bigger one counts at what selling it into the pool would actually return, so buying up a thin pool marks no profit. A coin whose price read fails counts at its last price instead of dropping the wallet. Replayed on real fills: Bag Lords went from 75 to 125 wallets and Up Only from 56 to 92, and nobody dropped off. Profile and Portfolio values are unchanged. Live now. - Your Base USDC says it's cash. Sale proceeds on Base sit in Portfolio as USDC, and tapping the row opened it like a coin. Pressing Sell answered "A Base token and linked EVM wallet are required.", which sent one trader looking for a wallet problem. Now it says the USDC is your cash, already in your balance, to spend on a Base coin or withdraw. Live now. In 278, Base USDC and BNB Chain USDT open a cash sheet instead: the dollar value, the amount, what it pays for, and Withdraw set to that token. - Takes on every coin. Yesterday they started on solana:6FhVPctYg363pQbs4iSvqyHe2cJzfsvFD96gePy6pump. Now any holder of any coin can post one. Takes lead the Holders list, each under its author's row, shown whole (up to 280 characters) without a tap. On a coin with none, a holder sees "Be the first: why are you holding X?" and everyone else reads "No takes yet · holders post them here". Once you hold a coin and haven't posted, your name on the hill carries a small speech bubble. Tap it or your rat to post. In 278. - The hill reads as a climb. Holders stand on steps that rise to the peak, and each step carries its multiple on the riser. These tags replace the ladder in yesterday's notes. Tap a tag to light everyone that far up. While you hold, a dotted path climbs from NOW at the shore to your rat, with milestones on the way. Rats stand on a solid shadow, and a holder at break-even stands just inside the shore instead of with its feet in the water. In 278. - See the losses on the rats. Underwater holders all stood knee-deep, whether they were 2% down or 45%. Now they sink with the loss: ankle-deep just under their buy, chest-deep near half. At 50% down or more they float belly-up with x eyes. Dead rats get their own room on the hill, so a crash reads as a pile: pulled back on a 96-holder crash, about 30 floating rats instead of a dozen. This needs a fresh price and a known buy. Your own rat, other players and family circles stay as they are. In 278. - A calmer arena. The ground no longer shakes on every dip. Everything runs on one 3-second beat: a busy coin shows fewer moments, never shorter ones, and at most 8 lit trades a minute. On busy coins, cuts went from 15–18 a minute to 9–11, and moments under 2 seconds went from up to 39% to none. Trades the light isn't on get no callout on the hill; the race line names the newest. At rest, the hill names your rat, NOW, the goal and one thing more, and tags hold their spot. In a busy minute, 7 tags at once became 4, and 35 jumps became 2. In 278. - Less on the coin page. Scroll a coin's Holders, Clusters, Activity or About list down and the tab bar slides away, as on Pump. With the arena off, the chart also slides up under the header and your bag card fades, so the list runs from the tabs down to Buy. Scroll back up and everything returns. Buy, Sell and any Before-you-enter warning stay put. That warning now shows over Buy only when something is flagged, instead of "Nothing flagged" on every coin. Net buyers and dry powder share one row of tiles above the takes instead of two blocks. In 278. - Know when there's an update. From this version on, the app tells you once when a newer one is in the store: "Update available", with Not now or Update. Each version asks once and never blocks you. Android checks Google Play and iPhone checks the App Store. In 278, so the first prompt comes with the update after it. *-Next starts clean. After a one-tap Sell, the "Sold X · Share" line stayed up for 14 seconds and rode along to the next coin, and so did other notices. Moving to another coin now clears them. A trade still sending keeps its progress line. In 278. - Exfil speaks Korean, Japanese and Chinese. All 3,314 lines of the app are now in Korean, Japanese, Traditional Chinese and Simplified Chinese, following your phone's language. They're machine translations by Claude Opus 5.5 using a 110-term trading glossary. The 1,339 lines about money and risk were also translated back into English and checked a second time. Native speakers haven't reviewed them yet, so if a line reads wrong, tell us. The web terminal stays in English for now. - Rats stand on their average buy. The hill placed each holder by their latest buy. One top holder bought most of their bag early and a little more at the top, and read 1.1× up when the bag was about 29×. Now each holder stands on the average price of the buys in the bag they hold, from their whole swap history. Sells come out at the average, and a bag sold out starts over. The rat sheet reads "Price vs average buy" with how many buys it averages ("average of 24 buys"), and still shows the latest and first buy. A wallet whose history is too long to read in full stands on its latest buy, as before. Already live on exfil.fun coin pages; in the app with the next update. - Takes get their own button and read calmer. A Takes button sits at the foot of the arena's side column, nearest your thumb, with the coin's count. It opens the takes in a sheet from the bottom, the way video apps open comments, with the post box at its foot. Every take and reply leads with its author's rat, dressed the way its owner dressed it. Tap it to open that rat on the coin. Votes show the holders-versus-everyone-else split only when the two sides disagree, in words: "Holders like it · others don't". Replies fit on one row, and times read "2h" instead of "2h 10m". The zoom buttons moved into the camera menu, and pinch still zooms. - Swipe means next coin. At the normal view, a one-finger drag now only moves between coins. A sideways drag no longer spins the hill by accident; pull back to the whole hill to turn it. Swipe down to go back to the coin before, and Next returns the way it came. Swipes catch sooner (they move on 64 points or a flick instead of 80) and allow for a curved thumb. You'll see a one-time hint: "Swipe up for the next coin". - The Arena switch is a curtain. Turning the arena off now slides the chart down over a hill that holds still, and lifts it off again. Before, the hill re-framed on every frame of the slide. It's 3–4 redraws a press instead of 40.
