Under the inertia of "completing tasks and earning points," what Sophon has provided is a shutdown schedule. On October 20, 2026, the project team issued an official announcement, planning to finally shut down the Sophon mainnet on November 30, with the deadline for asset withdrawal locked in even earlier at November 25 — a withdrawal window of approximately five weeks has been clearly written into the announcement. Compared to common security incidents or sudden attacks, this time the project team is proactively and orderly shutting down as planned: key infrastructure and related websites will gradually go offline after the mainnet closure, and the most striking reminder in the announcement is — assets remaining on the chain after the deadline may face the risk of permanent inaccessibility.
From the perspective of users on AirDrop Radar, this is no longer an opportunity line of "can I get more rewards," but a task line that must be completed quickly for exiting. At this stage, what is truly driven by time is the withdrawal of assets: including SOPH, ETH, USDC and other assets that can be withdrawn through claim.sophon.com, as well as various unstaked or Guard rewards that have yet to be claimed, which have been explicitly named by the official to be handled within the window period. Five weeks may not sound long, but once we cross the deadline of November 25, with the mainnet closing as planned on November 30 and infrastructure gradually going offline, the technical accessibility and actual retrievability of residual assets on the chain will sharply decline, which means users need to regard this shutdown as an "exit task with a clear deadline," rather than a new opportunity to observe leisurely.
Shutdown timetable triggers asset withdrawal countdown
From the timeline perspective, this shutdown is not a sudden blackout, but an "orderly exit" that has already been scheduled. On October 20, 2026, the Sophon project team released an announcement clearly stating that the mainnet will be shut down and provided two key dates in the same announcement: one is the asset withdrawal deadline of November 25, and the other is the planned final closure date of the mainnet on November 30. In other words, what users have for withdrawing SOPH, ETH, USDC, and other assets through existing paths is about a five-week window starting from the date of the announcement; after November 25, although the chain will still "live" until November 30, the official has already indicated that withdrawal paths will be significantly restricted, and key infrastructure and related websites will gradually go offline, with assets remaining on the chain potentially facing the risk of permanent inaccessibility. From the user's perspective, the significance of these two timelines has been clearly broken down by AirDrop Radar: November 25 is the "last evacuation day" in practical operation, while November 30 feels more like the endpoint of a complete system shutdown.
Within the approximately five-week window, different types of holders feel varying levels of time pressure. For active users who have been constantly watching the AirDrop Radar page and have relatively concentrated assets, this period is sufficient to complete multiple logins, check balances, and withdraw SOPH, ETH, USDC gradually through entrances like claim.sophon.com, while also handling staked or Guard rewards; this is more of a "portfolio organization" process. However, for users who have scattered multiple addresses on Sophon, participated in complex tasks, or even have a portion of their assets long "forgotten on the chain," five weeks mean they must complete inventory, confirm withdrawal paths, and clean up residual assets within a limited schedule. If they delay action until close to November 25, any mistake in the process may lead them directly into a phase of restricted withdrawal paths. Not to mention those deeply engaged participants who have deployed tools or strategies around Sophon; they need to consider the interconnected impact of asset withdrawal and infrastructure shutdown before the mainnet closes. Under this schedule, whether one can recognize which type of holder they belong to and arrange their withdrawal rhythm accordingly will determine whether these five weeks are a buffer for a calm exit or a high-pressure asset inventory assessment.
From participation to withdrawal: The role of Sophon in the air-drop line changes
From the perspective of AirDrop Radar, Sophon's position has quietly shifted: it is no longer a potential lead of "can we issue a decent air-drop," but has been included in the priority checklist of "safely taking away what is already on the chain." Since the official announcement of the mainnet shutdown plan on October 20, 2026, the focus surrounding Sophon on the AirDrop Radar page has shifted from interaction frequency and task rhythm to the timetable and withdrawal boundaries — what users first need to remember is that the mainnet will finally shut down on November 30, while the asset withdrawal deadline has been locked in early on November 25; this five-week buffer period itself has become the core information of the air-drop line. Rather than continuing to speculate if Sophon would design new incentives, it is better to acknowledge a fact: the story of this chain has entered its final chapter, and the key now is how to take a dignified bow.
In such a context, the meaning of "tasks" itself has also reversed. The usual tasks on AirDrop Radar are more like forward-looking participation paths — interacting, accumulating footprints, betting on future possible rewards; whereas the core action currently emphasized by the official for Sophon is the backward-looking "withdraw assets": through entrances like claim.sophon.com, reclaim SOPH, ETH, USDC from the chain while also cleaning up any unstaked and Guard rewards. For users, this is not an incremental task that can be optionally participated in, but a settlement problem concerning existing assets; it no longer cares whether you can get a little more, but rather whether you will have your existing chips locked on the soon-to-be-closed mainnet due to missing the November 25 deadline. With the planned final closure of the mainnet on November 30 and critical infrastructure and related websites gradually shutting down, the official has clearly reminded that any assets left on the chain at that time may face the risk of permanent inaccessibility. Therefore, Sophon has completed a role switch on AirDrop Radar — from "a field for seeking potential gains" to "a one-time asset inventory and settlement field," and what users should look at next is no longer new opportunities but whether their existing chips can be safely cashed out within this timeline.
Withdrawing SOPH and rewards: User choices within the five-week window
Starting from October 20, the time left for Sophon users to perform a "total liquidation" only extends to the cutoff point of November 25. For any address that already has capital exposure on Sophon, the first task is no longer to look for new tasks but to inventory their asset types one by one: SOPH spot balance, ETH, USDC held on-chain, and possibly overlooked other assets. From the perspective of AirDrop Radar, the core of this stage is to gather all assets tied to the Sophon mainnet into one understanding — they are all constrained by the same timeline and need to be withdrawn via official channels like claim.sophon.com before the deadline, or face the consequences of "possible permanent inaccessibility" as described in the official announcement.
Compared to simple token balances, many users tend to overlook the earnings and rewards lying in contracts. The official has already reminded in the announcement that besides SOPH, ETH, USDC and other assets, any staking rewards and Guard rewards that have yet to be claimed also need to be extracted before November 25, which means those regarded as "long-term locked positions, not in a hurry to move" are also forcibly included in the decision list of the five-week window. On AirDrop Radar, such assets and rewards are seen as different tiers under the same closure logic: the surface is the visible balance, while a deeper layer consists of unclaimed rights, and the priority of both in time dimension no longer differs.
Thus, during these five weeks, user choices begin to diverge. A more conservative group may take Sophon as an old account that is about to shut down, tending to withdraw all SOPH, ETH, USDC and all staking and Guard rewards within the window period, keeping only off-chain records as history; another group may think, with a few days' buffer before the mainnet finally closes, they will continue to observe whether the official provides more explanations or arrangements before deciding whether to completely withdraw. But regardless of which mindset, the time nodes have already been clearly outlined in the announcement and prominently marked by AirDrop Radar: what truly needs to be managed is not emotional attachment, but whether every single asset and reward in the user's address on the Sophon mainnet can complete one last orderly cash-out within this five-week window.
Orderly exit from non-security events and on-chain residual risks
First, it must be clarified that this is not a technical failure or a sudden attack, but a game plan of an orderly bow-out written in an announcement. Research briefs have defined this shutdown of Sophon as an active closure of the mainnet by the project team, and the official announcement on October 20, 2026, did not mention any attacks or security events as the reason, but directly provided the deadlines for asset withdrawals and the final timeline for mainnet shutdown. This means that what current users are facing is not an unexpected "system may crash at any time" black swan, but an exit route that has already been drawn — within the established five-week window, those who actively manage their assets will be able to exit this orderly conclusion unscathed.
The real risk has been pushed to the phase after infrastructure and websites gradually close down. The announcement has already pointed out that the mainnet will close on November 30, 2026, and that key infrastructure and related websites will systematically go offline thereafter, and assets still left on the chain at that time may face risks of permanent inaccessibility. For ordinary users, this "permanent inaccessibility" does not necessarily mean that assets have technically disappeared totally, but rather that the last convenient door has been closed: without official extraction entrances and without ready front-end and service support, even if the chain exists in some sense, the costs for individuals to re-access and move those residual assets will sharply increase, and many addresses will practically be locked in historical snapshots.
In such scenarios, the role of AirDrop Radar is not to make choices for users but to lay out risk boundaries and time nodes as clearly as possible in advance. Sophon's card has already marked this event as the project team actively shutting down the mainnet and presents the two critical anchors — the November 25 asset withdrawal deadline and the November 30 mainnet closure — synchronously, allowing addresses that are still hesitating to visually see the "withdrawal window" and "residual risks" separated by just a few days. For users who have already participated in SOPH, ETH, USDC, and staking or Guard rewards, this clear timeline reminder essentially highlights a bottom line: if the last active operation is not completed within the orderly exit window, then the subsequent story concerning Sophon can only be written into the immutable history on the chain, rather than on your balance sheet.
The endpoint of air-drop tasks: reminders brought by the Sophon case
The shutdown plan of Sophon has laid out a complete withdrawal timeline in front of participants: from the announcement on October 20, 2026, to the asset withdrawal deadline on November 25, and to the final closure of the mainnet on November 30, the official has clearly written down the risk that "overdue assets may face permanent inaccessibility." This means that for all users who have participated in SOPH, ETH, USDC, and staking or Guard rewards through claim.sophon.com, "the last active withdrawal" is no longer an annotation but an equally important part of the original "receiving an air-drop" — the true endpoint of the participation lifecycle is not the arrival of rewards, but your confirmation that you can continue to control these assets off-chain.
Looking ahead from the Sophon case, AirDrop Radar will also regard this type of "asset withdrawal tasks" as a regular part: before the withdrawal is eligible, it involves qualifying and task pathways; after the withdrawal, it concerns extraction and distribution, and around the clear extraction deadline, it reflects the changes in exit states and risk boundaries. In similar projects during orderly exits, the project team provides a clear timetable and risk alerts, while users can timely identify nodes like "extraction deadline" and "mainnet closure" on the AirDrop Radar cards, together completing the closed loop from participation to withdrawal. It remains to be observed whether more projects in the future will design orderly exit roadmaps in advance, similar to Sophon, when planning air-drops and task mechanisms, and whether AirDrop Radar can clearly mark these exit windows and potential loss boundaries in the visible journey of user participation over the long term.
