TLDR
Upbit halted Solana (SOL) deposits and withdrawals today following an unauthorized outflow from its Solana hot wallet, as confirmed in multiple reports (Upbit hack coverage).
- Roughly ?54 billion (~$3638 million) in Solana ecosystem tokens were drained (incident summary).
- The pause applies to Solana-based assets while systems undergo inspection (exchange response).
- Upbit says user losses will be reimbursed from its reserves (assurance to users).
Deep Dive
1. Upbit Halt
Upbit is the centralized exchange that froze Solana network deposits and withdrawals today. Reports detail an immediate suspension after detecting abnormal Solana hot-wallet activity (Upbit hack coverage, incident summary).
If you used Upbit for SOL or Solana tokens, transfers are temporarily paused. Monitor the customer center updates and your balances on the exchange.
2. Loss Estimate
Coverage places the loss around ?54 billion (about $3638 million), spanning SOL and multiple Solana ecosystem tokens like USDC, BONK, JUP, RAY, PYTH, ORCA and others (Upbit hack coverage, exchange response).
The breadth of affected Solana tokens suggests broad Solana network exposure in Upbits hot wallets. Price impact has been limited so far, but token-specific liquidity may be uneven during the pause.
3. User Impact
Upbit stated it moved assets to cold wallets, froze some stolen tokens on-chain, and will fully reimburse user losses from its own reserves, with services resuming after security checks (assurance to users, incident summary).
Risk note: Hot wallets on CEXs are exposed to online attack surfaces. Incidents can cause temporary withdrawal halts and localized liquidity stress in affected assets.
Your balance should remain whole per Upbits commitment. Operational downtime is the main friction. If you need near-term liquidity, monitor when Upbit reopens Solana transfers.
Conclusion
Upbit froze SOL and Solana token transfers today after a hot-wallet breach estimated at ?54 billion. The exchanges response prioritizes containment and user reimbursement. Near term, expect operational delays on Solana transfers via Upbit while security audits complete; broader market impact appears contained given the quick pause and recovery steps reported.
