When a blockchain undergoes a hard fork, users often assume their coins will be immediately accessible afterward, but the reality is more complex. The Zilliqa network completed a major protocol upgrade on September 2, 2026, that reassigned user balances from legacy addresses to new Ethereum Virtual Machine (EVM) compatible addresses, yet three days later, deposits and withdrawals remained frozen at multiple major exchanges, including Bitvavo, WhiteBit, and KuCoin. This disconnect between protocol-level changes and exchange operations reveals a critical gap in how crypto custody actually works.

What Exactly Happened During the Zilliqa Hard Fork?

A hard fork is a rule change that every node on a blockchain must adopt; after the fork activates, only the new rules apply. Zilliqa's September 2 fork did one specific thing: it moved ZIL token balances from the network's old legacy address format, which used Schnorr signatures for security, to a new Zilliqa EVM address format that follows Ethereum's standard. This change was necessary to make the network compatible with common crypto wallets and tools that users already understand.

The fork activated at block 34,844,968, which occurred around 12:58 UTC on September 2, 2026. By September 5, the Zilliqa blockchain had processed over 200,000 additional blocks, confirming the fork was unambiguously active and not pending. However, the protocol's work ended there. What happened next was entirely up to the exchanges.

Why Can't Exchanges Just Flip a Switch and Reopen Withdrawals?

This is where most users misunderstand the custody model. Zilliqa's protocol can reassign balances at the network level, but it cannot force an exchange to open its withdrawal gates. Each exchange holds a pooled balance of customer ZIL tokens in its own wallets and manages individual account allocations through its internal bookkeeping system. When the address format underneath that pooled balance changes, the exchange must perform several critical steps before it can safely let money out again.

According to Zilliqa's own announcement, exchanges are "working through their own testing before they restore ZIL deposits and withdrawals on their platforms". This testing phase involves moving the exchange's entire wallet infrastructure, address management system, and accounting records to the new side of the chain, then verifying that every customer's balance is correctly reflected. If something goes wrong during this process, the exchange is liable to its customers, not the protocol. That liability creates a strong incentive to move slowly and carefully.

What Does the Exchange Status Actually Tell You?

On September 5, 2026, independent checks of three participating exchanges revealed the state of play:

• Bitvavo: Already displayed ZIL on the ZILEVM network, indicating the balance reassignment had arrived, yet both deposit and withdrawal statuses showed "MAINTENANCE." Trading was active at the same time, meaning users could sell but not move coins.
• WhiteBit: Reported both deposits and withdrawals as disabled and still listed the old ZIL network label, suggesting the migration work had not yet begun.
• KuCoin: Likewise reported ZIL deposits and withdrawals as switched off, with no indication of progress toward reopening.

The network label itself serves as a useful status indicator. If your exchange shows "ZILEVM," the balance reassignment has completed there and only the transfer release is pending. If it still shows "ZIL," the provider has not yet migrated its systems. Either way, the message for users is the same: wait. None of the ten affected exchanges had committed to a reopening date.

How to Navigate a Frozen Withdrawal Situation?

• Check Your Provider's Status Page: Look for the withdrawal status indicator next to the withdrawal button in your exchange app, or visit the provider's official status page. This is your most reliable real-time source of information, not announcements or social media posts.
• Understand the Network Label Difference: If your exchange shows ZILEVM, the hard fork migration has reached that venue. If it shows the old ZIL network, the provider is still in the early stages. Both mean you cannot withdraw yet, but the label tells you how far along the process is.
• Document Everything for Support: If your balance is visible but cannot be moved, take screenshots of your account balance, the withdrawal status, and the date and time. Keep records of any support tickets you open, as this documentation may matter if there are disputes later.
• Recognize That Trading May Still Work: Some exchanges, like Bitvavo, kept trading active while withdrawals were frozen. This means you can sell your ZIL if you choose, but you cannot move it to another platform or wallet during this phase.

What About Users Who Hold ZIL in Their Own Wallets?

For self-custody users, the September 2 hard fork changed nothing. Anyone holding ZIL in a personal hardware wallet, software wallet, or other non-exchange custody solution was not affected by the protocol-level balance reassignment. The fork only impacted the ten exchanges that held pooled customer balances. Self-custodians already use the address format that works with their wallets, so there was no migration step required for them. This is one of the key reasons crypto advocates emphasize self-custody: you avoid the delays and dependencies that come with relying on an exchange's internal systems.

When Will the Next Wave of Exchanges Be Migrated?

Zilliqa announced a second hard fork planned for "mid-September" to migrate the next group of trading venues. However, this statement carries no firm deadline. "Mid-September" is a direction of intent, not a specific date. Zilliqa noted that address mappings for additional exchange partners were still being collected and verified, and the exact date would be confirmed once those mappings were settled. Anyone holding ZIL at an exchange not included in the September 2 group has not been forgotten, according to Zilliqa's statement, but the timing remains uncertain.

The core lesson here is that only your exchange has the answer to when you can withdraw again. Zilliqa can move balances at the protocol level, but it cannot control the timeline for when each venue completes its internal testing and decides to reopen transfers. That decision belongs entirely to the exchange, and it is driven by the exchange's own liability, operational capacity, and risk tolerance.
