Exchange Updates: TRX and ARK Deposit/Withdrawal Suspensions Amid Network Upgrades

·

In the fast-evolving world of cryptocurrency, timely updates from major exchanges are crucial for traders and investors to protect assets and plan strategies. Recently, several prominent digital asset platforms—including Huobi Global, OKEx, and Upbit—announced temporary suspensions of deposit and withdrawal services for specific tokens due to network upgrades and maintenance. These actions reflect the industry's ongoing commitment to security, stability, and long-term scalability.

This article breaks down the latest exchange announcements, explains the reasons behind service interruptions, and offers insights into how users can respond effectively during such events. We’ll also explore broader implications for blockchain networks undergoing upgrades and how traders can stay ahead in a dynamic market environment.

Why Exchanges Temporarily Suspend Token Services

Cryptocurrency exchanges routinely pause deposits or withdrawals when underlying blockchain networks undergo critical updates. These pauses are not signs of failure but proactive measures to ensure:

Such maintenance windows are especially common for projects implementing major consensus or architectural changes—like TRON (TRX) and Ark (ARK), both of which are currently experiencing network transitions.

Huobi Global Halts TRX Deposits and Withdrawals

Huobi Global has officially suspended TRX deposit and withdrawal services as of February 11, 2019, at 10:20 AM Singapore time. The halt was implemented due to scheduled wallet upgrades aimed at enhancing system performance and security.

While trading for TRX pairs remains unaffected, users are advised not to send TRX tokens to Huobi during this period. Doing so may result in permanent loss of funds, as incoming deposits cannot be processed until the upgrade is complete and services resume.

The TRON ecosystem frequently undergoes optimizations to support growing decentralized application (dApp) usage and bandwidth demands. Exchange wallet upgrades like this one ensure compatibility with the latest node software and smart contract standards.

OKEx Suspends ARK and NANO Services Due to Network Upgrades

OKEx has issued two separate maintenance notices affecting ARK and NANO token holders.

ARK Mainnet Upgrade Triggers Service Pause

To accommodate the ARK mainnet’s V2.1 upgrade, OKEx paused all ARK deposits and withdrawals starting at 12:00 HKT on February 11, 2019. The ARK V2.1 update introduces improved transaction processing speeds, enhanced smart bridge capabilities, and better developer tooling—key steps toward scalable cross-chain interoperability.

Users should expect delays in ARK-related transactions until the network stabilizes post-upgrade. OKEx will resume services once full node validation confirms network integrity.

NANO Wallet Upgrade Completed

Separately, OKEx had previously suspended NANO deposits and withdrawals at 4:00 PM HKT on the same day due to internal wallet upgrades. The maintenance is now complete, and normal operations have resumed.

NANO’s unique block-lattice architecture requires precise wallet synchronization to prevent balance inconsistencies. Regular upgrades help maintain its feeless, instant transaction model.

Upbit Temporarily Halts TRX Support

South Korea’s largest cryptocurrency exchange by volume, Upbit, also announced a temporary suspension of TRX deposit and withdrawal functions. The freeze took effect at 10:00 PM KST on February 11 and lasted until 2:00 AM KST the following day.

This short maintenance window allowed Upbit to align its infrastructure with TRON’s latest network parameters. As with other exchanges, TRX trading pairs remained active during the pause.

Given South Korea’s influential role in Asian crypto markets, any service change on Upbit often impacts regional price movements and trading volumes—making timely awareness essential for active traders.

bitFlyer Resolves Service Outage

Japan-based exchange bitFlyer experienced a brief service disruption around 3:11 AM JST on February 11. Some users reported difficulties accessing accounts or executing trades during the outage.

The platform quickly addressed the issue and confirmed full service restoration via its official Twitter channel. While no official cause was disclosed, such outages are typically linked to server load spikes, DDoS mitigation, or backend database synchronization.

bitFlyer remains one of Japan’s licensed and regulated crypto exchanges, adhering to strict Financial Services Agency (FSA) guidelines—ensuring rapid response protocols during technical incidents.

Sistemkoin Launches BitTorrent (BTT) Trading Pairs

In positive news, international digital asset platform Sistemkoin announced the listing of BitTorrent Token (BTT) on February 10, 2019 (Singapore time). New trading markets now include:

BTT leverages TRON’s high-throughput blockchain to incentivize file-sharing within the BitTorrent ecosystem. Its integration aims to revive peer-to-peer content distribution using tokenized rewards—a model that could reshape digital media economics.

The launch highlights growing interest in utility tokens tied to decentralized storage and bandwidth-sharing protocols.

Frequently Asked Questions (FAQ)

Q: Why do exchanges suspend deposits and withdrawals during upgrades?
A: Exchanges pause services to synchronize their wallets with updated blockchain protocols. This prevents lost funds, failed transactions, or mismatches in user balances during critical network transitions.

Q: Can I still trade TRX or ARK if deposits are paused?
A: Yes. Trading usually continues uninterrupted even when deposits or withdrawals are suspended. However, you won’t be able to transfer tokens in or out of the exchange until services resume.

Q: How can I stay updated on exchange maintenance schedules?
A: Follow official exchange blogs, social media channels (like Twitter/X), or trusted crypto news aggregators. Many platforms also send email alerts to registered users before planned downtimes.

Q: Is it safe to keep my tokens on an exchange during an upgrade?
A: Generally yes—exchanges implement these pauses precisely to protect user assets. However, for long-term holdings, consider storing tokens in a secure personal wallet.

Q: How long do these suspensions usually last?
A: Most pauses last between a few hours to several days, depending on the complexity of the upgrade. Projects like ARK or TRON may require extended windows due to consensus-level changes.

Q: What should I do if I accidentally send tokens during a suspension?
A: Contact the exchange’s support team immediately with your transaction ID (TXID). In most cases, once services resume, they can credit your account manually—if the funds were sent to the correct address.
