TL;DR

Upbit, the largest crypto exchange in South Korea, suspended Solana-related transfers after a $36 million hot wallet breach involving unauthorized movements on the blockchain.
The company reacted by moving assets to cold storage and freezing withdrawals across the platform.
The incident occurred less than twenty-four hours after Dunamu finalized a $10 billion acquisition with Naver, increasing scrutiny over security practices during corporate expansion.

South Korea’s top exchange has temporarily halted Solana transactions after detecting $36 million in unauthorized transfers from a hot wallet. The breach drew immediate attention because it emerged right after Dunamu, Upbit’s parent company, completed a $10 billion deal with Naver.

Trading services remain active, though users cannot currently deposit or withdraw funds while the exchange conducts a full review. Several industry analysts suggest that Upbit’s rapid response could help mitigate long-term market impact, pointing out that exchanges with strong reserves typically recover faster from security incidents 

Solana Hot Wallet Incident Raises Security Questions

Upbit reported unusual withdrawals during normal operating hours and reacted by blocking Solana transfers and relocating remaining funds into cold storage. Blockchain analytics firms and token issuers are collaborating on on-chain freezing efforts. Independent security specialists stated that the speed of the response likely prevented additional losses across other wallets integrated with the exchange.

The exchange clarified that only a single Solana wallet was compromised, while other networks and core systems remain intact. User funds will be fully reimbursed, and no customer action is required.

Corporate Expansion Collides With Risk Management

The breach surfaced just a day after Dunamu finalized its $10 billion agreement with Naver Financial, which could support a future U.S. listing. Local regulators have initiated inspections during this transition, focusing on risk control and compliance. Analysts argue that rapid expansion should reinforce investment in cold-wallet technology and independent auditing, particularly for high-speed networks like Solana.  

Market Reaction and Industry Perspective

Solana’s price remained stable despite the incident, showing solid liquidity and steady trading demand. Security researchers emphasize that the biggest attacks repeatedly target exchange-managed custodial wallets, not blockchain protocols, supporting claims that decentralized networks are structurally more secure. Market commentators highlight that long-term investor confidence has not weakened, pointing out that Solana continues attracting institutional interest, new application developers and deeper ecosystem partnerships.

Upbit is cooperating with regulators, cybersecurity experts and blockchain developers to recover compromised funds and restore services as soon as possible. The case demonstrates that market growth can align with stronger operational safeguards and broader Web3 development.
