new $FILL is live.
Same protocol, same engine, same wallet, correctly named this time. The engine has already verified and registered the new token automatically.
Refunds for the retired contract are now open at
fill.fun/#recovery
We reconstructed the old token's complete trade history, every buy and sell across 496 wallets.
Enter your wallet on the site: it's verified against that on-chain record, and any wallet that took a net loss joins the public repayment queue.
10% of all protocol fees repay claimants automatically until each one is made whole. Every claim, every payout, every transaction, visible on the site and on-chain.

An apology, and a relaunch.
We launched $FILL earlier with a typo in the token name. Token names are permanent on-chain, no edit button exists. We had a choice: live with a misspelled protocol token forever, or fix it now while we're a day old. We're fixing it.
What this means:
The old contract is retired. The site, the engine, and every future post point only at the new token.
Making it right:
10% of all protocol fees from here on go into a recovery pool for everyone who lost money on the old token,until every one of them is made whole. Not an airdrop, not diluted supply, real fee revenue, paid until the debt is cleared. If you bought the old token, your loss is on our books, and the protocol works it off.
The protocol itself never blinked — the engine kept trading, fees kept collecting, buybacks kept accruing. This was a naming mistake, not a protocol failure, and we'd rather take the embarrassment today than carry a typo forever.

Everything you see in the world was imagined first. Before it had value. Before it had attention. Before anyone believed in it.
Most people can only believe in things after they exist.
If you can imagine something clearly enough, it stops being impossible. It becomes real
Over time, more people will arrive. They’ll see what was here. They’ll say it was obvious.
Imagine this was the moment everything started.
Imagine this is it.
Imagine being early without realizing how early you are.
Imagine watching belief turn into reality.

we shipped a typo, retired the contract same day, relaunched correctly, rebuilt the victim list from 2,600+ on-chain trades, and started repaying people from fee revenue within hours.
mistakes are free content when your system is honest.
your token, your risk dial:
conservative — 3-10x, NYSE hours, strong signals only
balanced — 5-25x, extended sessions
degen — venue max, every session
off — no trading, fees go straight to burns
pick at launch. the engine obeys it forever.
the engine moves its own money across three chains. fees on robinhood chain → bridged to arbitrum → margin on hyperliquid.
it quotes the route, refuses bad pricing, keeps reserves for burns and refunds, and signs everything itself.
"what if the trade loses", hard stop at -40% of that position's collateral, cooldown after, engine gets pickier on the next entry,
never adds to a loser. losses cost a slice of one token's fee income. that's the whole blast radius.
the refund system nobody asked us to build: lost money on our retired first contract?
paste your wallet at fill.fun. it's checked against the on-chain trade history and the engine repays you automatically from 10% of protocol fees.
how a trade actually happens:
your token's fees accrue as its trading budget
momentum/RSI signal clears the threshold
position opens, sized ONLY by that budget
3-stage exit: breakeven stop → partial take-profits → trailing
profit buys your token and burns it
every step logged, every step visible.
pick a strategy when you launch:
conservative — 3-10x, NYSE hours only, strong signals only
balanced — 5-25x, extended sessions
degen — venue max leverage, every session
off — no trading, fees go straight to buybacks
your token, your risk profile.
nobody deposits anything into FILL. read that again. the engine only trades creator fees that were already earned.
worst case for a holder is a smaller buyback — never a lost deposit.
when Ostium got exploited, the engine detected the halt on-chain and stopped trading before we even saw the news. then we made it dual-venue.
it now trades Hyperliquid equity perps and switches back to Ostium automatically when they're back.
good to see. respect for the balance-sheet contribution to LP recovery — that's how you rebuild trust after an incident.
for FILL: nothing to do. the engine checks Ostium's contracts on-chain before every trade, so when they unpause, it re-enables them as a venue automatically — same way it detected the halt and rerouted to Hyperliquid within minutes of the exploit.
we never stopped trading. now we'll have two venues instead of one.
Update: We are working toward a relaunch this week. We will provide a notification 24 hours before trading resumes. Final checks are being done by our auditors, third-party cybersecurity experts, and engineering team.
What this means for positions when trading resumes:
• They are marked to the live market price at the time trading resumes.
• Traders will not be liquidated based on price movements that happened while trading was paused.
• If a trader’s position is below its liquidation threshold at the live market price when trading resumes, it will be liquidated.
• Pending orders will carry over exactly as they are.
For affected liquidity providers, our team is working hard on a recovery plan. Ostium Labs intends to contribute from its own balance sheet alongside new and existing partners. We know this is the update you are waiting for, and will share it as soon as we can.
Please trust only official Ostium channels. We will share all updates here on X and on our telegram announcements channel. We will never DM you first or ask for your keys, seed phrase, or funds.
More to come.
