Upbit to Suspend Hedera (HBAR) Deposits and Withdrawals From 8 PM on October 28

Trading Stays Open While Transfers Pause

Upbit, South Korea's largest cryptocurrency exchange, will suspend Hedera (HBAR) deposits and withdrawals from 8:00 PM Korea time on Wednesday, October 28, the venue announced on Monday, October 26. The halt is tied to a scheduled Hedera network upgrade and stays in force until the exchange has confirmed the network is stable after the change, with a separate notice to follow once transfers can resume. The suspension covers HBAR movements on the Hedera network specifically, and it does not touch trading: Upbit's notice confirms HBAR trading remains fully supported throughout the upgrade window. The measure concerns transfers rather than markets, and the announcement makes no reference to the HBAR price. For holders, the practical effect from Wednesday evening is a two-track market: orders keep matching while the rails for moving HBAR in and out of the venue go dark for an undetermined period. Exchanges take this precaution before protocol changes that alter a blockchain's ledger rules, because a network segment still running old code while the rest of the network moves ahead can misprocess incoming transfers, and funds credited on the wrong rules are hard to reconcile. Upbit framed the step as protection for user funds during the upgrade, and its wording places the timing burden on users: any deposit arriving near the cutoff may fail to post normally. What distinguishes this halt is its open-ended shape: the notice names no reopening hour and makes resumption a function of verification rather than of the clock. Upbit did not disclose which upgrade Hedera (HBAR) is deploying, and the notice leaves the technical scope of the change to the protocol's own channels. The exchange's announcement, published at the start of the lead-up window, is the primary record for every condition described here.

Deposits Filed Mid-Halt Face the Tightest Rules

Upbit's operational fine print concentrates risk on the moment of the cutoff. A deposit filed shortly before the suspension begins may not be reflected normally, the notice states, and HBAR sent during the halt may never reach the recipient's account, with recovery possibly difficult. Two adjacent services stop at the same hour: deposit-return processing and the registration of new withdrawal addresses both pause, and anything filed during the window is handled sequentially once transfers resume. The notice also addresses a subtler scenario around unscheduled maintenance. If deposits or withdrawals occur on some networks near the suspension window, or during an unannounced check, the exchange's wallet system cannot process them while the maintenance runs. Those transactions are verified after the maintenance ends and then credited one by one, which can leave a balance missing from an account even after the network itself is back online. Sequential crediting means balances may appear in batches rather than all at once. Network congestion, the notice adds, may delay deposit processing independently of the upgrade. The technical backdrop explains the caution. Hedera (HBAR) settles transactions on hashgraph, a directed acyclic graph in which events are ordered through gossip between nodes rather than through blocks assembled in sequence, so an exchange's internal ledger must track the network's state precisely through an upgrade. A version mismatch between the network and a venue's own records is the classic cause of miscredited deposits, which is the failure mode this notice is built to prevent. The halt is scoped to HBAR on the Hedera network: the notice treats other assets' transfer rails as unaffected, and other venues listing HBAR set their own timing. The exchange will announce resumption through a separate notice, and until then users have no fixed reference point for when queued transactions clear.

Our reading is that the binding constraint here is not the upgrade itself but the verification step after it. HBAR's tape has swung hard in recent sessions, including one in which the token staged a 4.5% rebound from a low near $0.08275. The notice's own rules make mid-halt transfers the worst possible action: funds sent after 8:00 PM Korea time on Wednesday may sit uncredited with uncertain recovery. Holders who intend to move HBAR should settle transfers well before the cutoff, and anyone weighing another venue can compare options in our Best Crypto Exchanges guide.

Trading remains open on Upbit throughout, and the resumption notice, once it lands, is the event that fixes how long the halt actually lasts.
