Ostium

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.

Accounts may appear in the replies pretending to be us. We are not circulating recovery forms and will never ask for your keys, seed phrase, or funds. Please don't click any suspicious links.

An update on where things stand: What happened On July 15, Ostium’s LP (liquidity provider) vault was exploited for 23,752,746 USDC. Based on our ongoing investigation, the attacker compromised off-chain infrastructure related to the system that feeds prices into the protocol. The attacker then submitted illegitimate price reports that were manipulated to appear as valid, opening and instantly closing a series of large positions to extract an artificial profit from the vault. By design, trader collateral sits in a separate, isolated contract and is not affected, with all positions remaining open. Our response We are working with Mandiant, zeroShadow, Collisionless, and SEAL 911, alongside law enforcement, and coordinating with exchanges, bridges, and stablecoin issuers. Within 60 minutes of the first exploit transaction, we coordinated to pause trading and freeze all trading contracts. Currently, all of our engineering efforts are focused on isolating and hardening the infrastructure needed to enable a secure re-launch. What is next Impacted liquidity providers and the safe resumption of trading remain our top priority, and we are working around the clock towards the path forward. As a reminder, we will give at least 24 hours notice before trading contracts are unfrozen. Upon re-open, trader positions will be marked to the price at re-open, independent of interim price movements. Please trust only official channels. We will never DM you first or ask for your keys, seed phrase, or funds. If you have any leads, information, or resources to help with the investigation, reach us at: TIPS@ostium.io.

A Security Update: Trading remains paused following the security incident. User positions remain open and unmodifiable, and trader margin remains unmoved in frozen trading smart contracts. The team will continue to provide updates as they become available regarding a timeline both to the resumption of smart contract activity and the recovery of funds. Over the past 14 hours, the team has been in continuous coordination with relevant authorities, SEAL 911, and multiple security researchers. Several teams are working full-time to track the movement of funds and support the investigation. We are thankful for the support of countless individuals who have assisted throughout. We remain focused on resolving this incident around the clock and will share further status updates as soon as we are able.

Update: All trader funds and open positions are currently preserved as-is (frozen). Funds in the trading storage contract are paused. The team is actively investigating with relevant security experts. We will provide updates as they come.

We are aware of the issue with the OLP vault. We have paused all trading. The team is investigating.

This morning, between 14:18–14:23 UTC, Ostium experienced a security issue leading to a loss of funds from the public OLP vault. Our team identified the issue within minutes and immediately began taking steps to contain it, including coordinating to pause trading contracts within the hour. We are working closely with relevant law enforcement authorities, SEAL 911, and third-party cybersecurity experts. No founder ever wants to deliver an update like this. We recognize the responsibility that comes with building infrastructure that people choose to use and trust. We take that responsibility seriously, and our focus is on resolution and responding with transparency and accuracy. To the stablecoin issuers, bridges, protocols, and security partners who have moved quickly to assist us: thank you for your continued support. We will continue to provide updates as they arise.

@merubahnasibbb @greatremz @okx The best place to trade gold onchain.

@greatremz @okx i use ostium for trade gold

unpopular opinion if you're in crypto & you only talk about it without using any product you are ngm i track how often i actually open crypto apps vs how often i talk about them these are the ones i open almost every day: @okx for buying & managing everything in one place... the UI stays out of my way, which is all i want from an exchange @Bybit_Official for P2P, when i need to move between fiat & crypto quickly, it's the fastest option i've found @Chainflip for cross-chain swaps. native assets, no wrapping, no bridge anxiety. i swap BTC to ETH to SOL to TRON without thinking about which chain i'm on, yep that's the bar now @Ostium for onchain exposure to forex, commodities, indices & also crypto... real world markets are accessible without leaving crypto. this particular one changed how i think about portfolio construction @bitrefill for spending, gift cards, mobile top-ups, everyday purchases... the app that makes crypto feel like money instead of an investment the gap between i'm in crypto & i use crypto is bigger than people admit bcause adoption compounds when you use it & your friend asks how what's in your daily rotation?
