Ostium has laid out a recovery plan that makes 3,321 wallets whole, while 345 others are being asked to pick between options that the company hasn't detailed publicly. The split matters because those 345 wallets are the ones still exposed to whatever went wrong with the platform's off-chain systems, and they won't get the same clean resolution as the majority.
The plan is the first concrete accounting of who gets paid and who doesn't since the incident. Ostium hasn't said what criteria separated the two groups, or whether the 345 will be offered cash, tokens, or something else. That silence is already shaping how users are reading the announcement.
Who gets repaid, and who doesn't
Full repayment for 3,321 wallets is the part of the plan Ostium can point to as a clean win. Those users are getting their balances back without conditions attached, according to the company's outline. For a platform trying to steady itself after a security failure, that's the number it wants people to focus on.
The 345 wallets left out of that group are a different story. They've been told they can choose an option, but Ostium hasn't published what those options are, how they'll be valued, or when the choice has to be made. Until that's clear, the recovery plan is really two plans — one finished, one still being written.
Off-chain infrastructure is the soft spot
The Ostium incident points at a problem that keeps showing up across DeFi: the parts of a protocol that live off-chain are the hardest to secure and the hardest to make whole after a failure. Smart contracts can be audited, paused, or forked. Off-chain systems — the servers, keys, and operational processes that connect a protocol to the outside world — don't offer the same clean recovery path.
That's not a claim Ostium has made about its own architecture. It's what the shape of the recovery plan implies. If the failure had been contained to on-chain logic, the repayment math would likely look different. The fact that 345 wallets are being handled separately suggests the damage didn't fall neatly into one bucket.
Trust is the slower repair
Getting 3,321 wallets repaid in full is measurable. Rebuilding trust is not. DeFi users tend to judge platforms less on whether an incident happens and more on how the response is handled — who gets made whole first, how transparent the process is, and whether the people left waiting are given real information or vague assurances.
Ostium's plan does one of those things well and leaves the other open. The 345 wallets are the test case. If their options turn out to be worth meaningfully less than full repayment, or if the process drags, the headline number of 3,321 won't do much to calm the users who are still watching.
What the 345 are waiting for
The next concrete step is Ostium publishing the terms for those 345 wallets — what the options are, how they're valued, and the deadline for choosing. Until that happens, the recovery plan is half a plan. The company has committed to full repayment for the majority; it hasn't yet committed to anything specific for the rest.
That gap is where the story goes next. Ostium users in the 345 group don't have a repayment date, a valuation, or a stated deadline. They have an option to choose from, and the details of that choice are still pending.
