Day 24 of building a trading app we never had - The web terminal reads like the app. exfil.fun/trade puts INTEL cards and the trades that matter (whales, the dev, the top 10, sells into you) in the right column. Drag the trade window anywhere. Every coin has its own link, Back and Forward step between coins, visitors can open any coin, invites work on the web, and there’s a Portfolio page. NOTE: It's still beta and as always keep sharing your feedback. - Follow any wallet. Search finds coins, traders and wallets in one field. Follow any Solana wallet and its buys and sells reach you as pushes; you see its latest trades before you follow. Every profile now charts its PnL, and yours opens on your holdings. - Meet Whales. A coin’s biggest sellers in one list, its biggest buyers a toggle away, with “Holders only” and what each one is doing now. A whale’s linked wallets fold into one row, and dumpers wear bandit masks on the hill. In 310. - See every holder’s bag. The Holders tab counts “Hold $100+” across every holder, not just the top 100, with a bag sizes sheet and who has never sold. In 310. Know the dev’s record. The dev sheet lists their past coins, how high each one ran and where it is now. - See who’s selling into you. “Taking profit” tags big holders selling part of their bag above cost. A top holder who keeps selling, directly or through wallets they fund, stands on the SELLING perch opposite the dev. - Dry powder on the hill. The arena column shows the cash held by the coin’s $10K+ holders against its market cap, like “$696K · 4× mcap”. - Trades show up faster. Live trades arrive about 1.5 s after the block, down from nearly 5 s, and Activity scrolls back to a coin’s first trade. One-tap Sell goes out on the tap, even in thin pools. - MEV Protect on every trade. Solana buys and sells now go out through Helius MEV Protect, which skips block leaders linked to sandwich attacks. It’s been on since 11:37 UTC today; none of the first 34 trades needed a fallback. Live now. - Meet the crew. 13 free skins in Dress your rat: Ronin, Medic, Captain, Skater, Miner and more. Other players see yours on the hill. - Slippage starts at 1%. If the price outruns your trade, you can send that one trade again at 3, 5, 10 or 20% without changing your default.

we have 1,500+ EXFIL token holders now i want to hear from every one of you in the next 48h not using the app yet? tell me why and what will get you using the app already using the app? tell me what you need to make this your main trading app. my goal is to 10x users and volume in 30 days and build with the people who own it DM me and I will personally onboard you to the app

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.”

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.

Day 21 of building a trading app we never had - Meet Call-in. Ask any wallet what it did. Tap "Call in this rat" on a holder, "Call in the family" on a family, or "Call in the holders" before you Drop in. Answers are built only from the facts on the sheet you're looking at, and any line with a number that isn't on that sheet is dropped. It says what a wallet did, never why, and if you ask whether to buy, it says "I don't make calls. I just take them." Live now. - See what you've paid in trenches tax. Paste a pump.fun or Fomo wallet into exfil.fun/fees and get its receipt for the last six months, line by line: the app's fee, creator fees, pool fees, Solana network fees and tips, all read from the wallet's own transactions. It projects the next 12 months from your last 30 days and puts the app's rate next to Exfil's 0.375%, with a third of every Exfil fee back in solana:6FhVPctYg363pQbs4iSvqyHe2cJzfsvFD96gePy6pump. Your wallet's rat peeks over the top, and Post on X shares the receipt. Nothing to connect, no sign-in. Live now. - Closed trades list straight away. A coin you sell out of now shows in Portfolio › Closed at once. Before, it disappeared from both Open and Closed for 30 minutes. Live now. - Open bags stop going blank. If the price source refused one coin, every bag in that wallet lost its price and balance. Now only that coin goes unpriced. Coins you sold or sent away outside Exfil leave Open instead of sitting there with "—", and totals and leaderboards still count their trades. Before this, 51 of 300 open rows across all traders showed "—". This fixes 43 of them; the other 8 are dead pools and say "Price unavailable". Live now. - Find the buy behind a routed trade. When a holder buys through Relay, a bundler or a solver, the swap is filed under the router, so the holder showed "no buy seen". That was 8 of the top 30 holders on TORCH (Robinhood Chain), 10 of 30 on a Base coin and 14 of 30 on a BNB Chain coin. Exfil now counts the coin arriving in the wallet in that same transaction as the holder's buy, at that fill's price, so their entry, place on the hill and hold history show up. This works on Robinhood Chain, Base and BNB Chain. A plain wallet-to-wallet transfer still isn't counted as a buy, and Robinhood Chain's burn address now reads "Burn address". Live now. - Leaderboards count cross-chain trades right. A Robinhood Chain sell-all that came out a hair over the recorded buy (0.0002–0.011%) voided the bag and hid real losses from realised PnL. Those trades now close with their cost known. Coins recorded without a name no longer read "TOKEN". Weekly leagues now value a Robinhood, Base or BNB Chain coin with no market at $0, the same as a Solana coin, so a drained pool no longer counts as a win. Live now. - Your rat's name follows you. A name belongs to the player, not one wallet. Switch to or import another wallet and your name moves with you, 30-day lock included, on the app you already have. A wallet that already has its own name keeps it. Live now. - exfil.fun fits phones. On a phone, the homepage now plays vertical cuts of the hill, the dive and the deep loop. Before, it showed a cropped 16:9 strip that cut the hill in half and lost the scout rat. Live now. - Your trades on the skyline strip. With the arena on, the small price strip at the top marks each of your Exfil trades in the coin: a blue dot for a buy, a blue ring for a sell. They stay even after you've sold out, the same as on the chart. In 1.1.38, live now. - Meet Takes. Post your take on a coin from the wallet that holds it. Each take keeps a receipt of your bag, so everyone can see what you did after, like "Sold all of it · seen 41m after the take". Anyone signed in can reply and vote. Votes are split between holders and everyone else, and marked SPLIT when the two sides disagree. Takes show under holder rows, at the top of the poster's rat sheet, and in a Takes tile on the strip that flies the camera to each poster. Each person gets one live take per coin. Links, handles, other coins' addresses and slurs are refused, and report and block are a tap away. Starting on solana:6FhVPctYg363pQbs4iSvqyHe2cJzfsvFD96gePy6pump. - Read the hill at a glance. The live-price ring now reads "NOW $43.3K", or "NOW $311.6K · ATH" at the high. A ladder down the hill's left edge marks 100× · 10× · 2× · NOW · underwater, each rung level with its ring. The strip's tiles now have labels: Families, Top traders, ≥1% held, Buying, Selling. Signed-in traders see a three-line intro once, and an ⓘ after the counts brings it back. A trader we spoke with couldn't tell what the rats meant. - Know the sides before you buy. Before you Drop in, the race line describes the top 100 holders in plain words: "▲ 31 in profit · ▼ 64 underwater". "Ahead" and "behind" only mean something once you hold, so after you buy, the line switches to ahead and behind your entry, as before. - The hill takes the coin's mood. When a coin is up 15%+ in the hour, the field turns gold and the rats rise on their toes. On a fall, the field goes cold and the rats hunch. A coin 70%+ below its peak with a flat hour sits at dusk. A sharp 5-minute drop now shows in the header ("−14.8% · Past 5 min"), so the field never goes cold under a green hour. Heights, the waterline and the angle stay the same. - Big moments hold the stage. A whale's buy (with how many times the usual buy it is), a whole-bag exit or a group's first appearance now stays up for 5.5 seconds with a bigger caption, instead of fading after about 2. Each one has its own Share button. The picture shows the arena with the moment's words and your invite link, never your name. - Next lands on a full hill. While you watch one coin, Exfil reads the next coin's holders, buys and chart, so Next opens with everything already in place. In our test, all 5 Next arrivals opened full at once. Before, they opened empty and took 2.6 to 22 seconds to read every holder (median 8.6 s). Next now cuts to the coin and lifts it in instead of sliding. - The arena stops contradicting itself. The race line no longer says "quiet for a minute" while the hill shows a $158 buy: the newest trade is now anyone's, and a wallet outside the top 100 shows as "someone". A group tile with a checked zero keeps its place but is muted and opens nothing. The two "of 100" counts now have different names: "checking buys 72 of 100" on the strip and "12 of 100 traced" on the dev's crew. - See a coin's top traders. Search said "1 top trader" while the coin page showed 0, because the page only counted traders who still held. The coin page now names every top trader the list counts, including ones who traded in the last 24 hours and left, with what they did ("Sold $3.0K · bought $2.7K in 24h", "Not a top-100 holder now"). Tap the gold "N top traders" in Search to open the coin on that list. - "Got by transfer", not "no buy seen". When the chain shows a holder got the coin from another wallet, their row says "got by transfer" and their rat sheet says "Tokens arrived by transfer". "No buy seen" now means the read looked and found none, and a row whose read hasn't come back shows "—". On TORCH, 6 of the 7 holders with no buy turned out to be transfers. Robinhood Chain, Base and BNB Chain for now. - Latest buy and first buy, both on the rat sheet. The big multiple compares the price with the wallet's latest buy, but Diamond Paws counts from its first. The line now says "Price vs latest buy" with how long ago that buy was. When the first buy was at a different price, a second line adds it, like "First buy $0.001964 · 2d ago · now 5.5×". - "Before you enter" with the arena off. Every coin page now shows the check just above Buy and Sell: the worst fact in its colour ("The top 10 wallets hold 76% of supply · 1 warning"), or "Nothing flagged". Tap it to see every fact. Before, you had to open Review and expand it. - Buy any amount. The buy chips now end with "Type $ amount", the same as Sell. It opens Review with the keyboard up and quotes nothing until you type an amount. - Your look follows your account. Import your Phantom key, switch to that wallet, and your scout keeps its outfit. On a new phone or after a reinstall, your look comes back. - Copy that reads like a trading app. We rewrote 225 strings: facts in trader shorthand, one spelling each for PnL and realised, "arena" and "hill" everywhere, and caveats moved into the ⓘ sheets. Disclaimers across the app went from 38 to 5. - Cream means selected, green means money. Selected chips, tabs and tiles now use the arena's cream. Green is kept for Drop in and profit. Sizes, colours and corners across the app now come from one shared set. - Smoother zoom. The arena's zoom buttons now glide a step over 0.3 seconds instead of jumping. - The dev stands whole. When the dev has moved his bag, his perch shows the full character instead of a waist-up pose that looked cut off.
