Upbit Suspends TRON (TRX) Deposits and Withdrawals From 9 PM KST on October 31

One Notice Pauses Seven Assets at 21:00 KST

Move any funds you hold on Upbit over the TRON (TRX) network before 21:00 KST on Saturday, October 31, which is 12:00 UTC. The South Korean exchange published its notice on October 31 and cited a wallet upgrade as the reason: deposits and withdrawals for every asset running on the TRON chain stop at that hour. Five tokens face a full stop on both sides: BitTorrent (BTT), JUST (JST), SUN, TRX and Tether (USDT). Two more, APENFT and WIN, keep deposits open but lose withdrawals, because the exchange credits both as airdrops and handles them outside the standard deposit flow. Spot trading on all seven continues without interruption, so the TRON price keeps forming in the market even as transfers pause. The notice sets the boundary precisely. From the cutoff, incoming deposits stop counting toward accounts, and outbound withdrawals queue for a later window. Deposit returns, the service through which a user asks the exchange to send back an uncredited deposit, stop in the same window, and so does the registration of new crypto wallet addresses for withdrawals. Both resume after the upgrade and will be processed sequentially, in arrival order, per the announcement. Upbit offered no technical detail on what the upgrade changes, only that it sits on the wallet side of its custody. Custodial venues generate deposit addresses from an HD wallet tree, so maintenance at that layer touches every asset sharing the chain, which is why one notice covers seven tokens at once. It also explains the split treatment of APENFT, an NFT-focused project, and WIN: the notice puts their withdrawal-only status down to the airdrop origin, since those tokens reached users without a TRON (TRX) chain deposit. Balances stay in place throughout, and the restriction covers movement on and off the platform only.

The sharpest warning concerns timing rather than technology. Deposits submitted close to the cutoff may not be reflected at all, and the exchange states plainly that recovery in such cases can be difficult. That puts the burden on users to stop transfers well ahead of 21:00 KST, not at it. Deposits that do land during the maintenance still reach the TRON chain, but Upbit confirms them only after the upgrade ends, which delays the account credit by an unquantified period. The window itself has no end time: the venue says transfers resume once it confirms network stability and posts a separate announcement. The affected set is narrow but economically heavy. The Tron blockchain is a dominant rail for stablecoin settlement, and TRON DAO reported the chain settled $2.21 trillion in stablecoins in the third quarter, with Tether's USDT the largest share of that flow. Upbit users holding USDT on the TRON (TRX) network specifically should check the network field on any withdrawal request, because the same token issued on other chains is untouched. The pause also lands while on-chain activity stays high: Tron's 30-day revenue has outpaced Ethereum's in recent COINOTAG reporting, and that usage continues independently of one venue's maintenance. Nor is the action unusual for the venue. Upbit has run a series of short network pauses this month: Cosmos (ATOM) deposits and withdrawals stopped on October 28, IOST deposits and withdrawals stopped on October 21, and MultiversX (EGLD) withdrawals stopped the same day. Each notice followed the same shape, with trading left open and service restored after a stability check. The sweep is wide for a single network, touching five altcoins plus two airdrop tokens in one announcement.

What If You Miss the Cutoff?

The notice leaves that question open. COINOTAG's read is that the event is operational, not directional: live market data shows TRX down 9.1% over the past 24 hours, and spot trading runs throughout the pause, so no market mechanism is removed. The exposure sits with late senders. A deposit transmitted near or after 21:00 KST enters a queue with no confirmed reopening date, and the announcement sets no deadline for clearing the backlog. Users who miss the window keep their balances but cannot move them until Upbit posts its stability notice, and that announcement carries no date.
