Why is Whitechain migrating to a Layer 2?

There are several reasons why Whitechain is migrating to a Layer 2 network:

• Security, inherited from Ethereum. On the L2, chain data is published and settled on Ethereum, so Whitechain inherits Ethereum's security and data-durability guarantees instead of carrying its own.
• Less centralization. The old L1 uses a single-validator Proof of Authority model. Moving to the OP Stack is a step away from that toward decentralized sequencing over time.
• Lower upgrade complexity and better performance. The OP Stack separates execution, data availability, and settlement into distinct layers, which simplifies upgrades and sets up later performance work.
• Shared ecosystem and tooling. The OP Stack also underlies Base, Optimism, and the Superchain, which gives Whitechain shared tooling and a path toward decentralized sequencing.

The current Whitechain L1 is being replaced by a new Whitechain L2, and at the moment of the switch, the entire state of the old chain (every balance, contract, and storage slot) is copied into the new chain, so everything continues at the same addresses. 

Which actions are required for the migration? 

There is no action required. You do not need to claim, swap, unlock, re-register, or move anything. At the snapshot, your WBT balance will be carried over to L2 exactly as it stands at the same address. If you keep WBT on WhiteBIT, the exchange handles the transition for you. If you self-custody, your balance appears on L2 at the same address, controlled by the same seed phrase and the same private key. The one thing you do, once, is to add the L2 network (its chain ID and RPC URL) to your wallet so you can see your balance and transact. Those L2 values will be published before the Mainnet launch.

What exactly is preserved, and what is not?

The L2 Mainnet launch date is not yet announced. The snapshot of the L1, the L2 launch, and the domain cut-over all happen on the same day. Whitechain publishes migration dates on X, in the Telegram channel, and on the migration page.

How is a scam defined during the migration?

Please note that there is no manual migration step, and no legitimate support agent will ever ask for your seed phrase, private key, or a wallet signature to complete a migration step. Do not connect your wallet or share any keys. Confirm any information through an official channel first.

Whitechain publishes migration dates in only three places: X (https://x.com/Whitechain_io), the Telegram channel (https://t.me/Whitechain_io), and the migration page in the docs. As of now, no date is published. Check any date you see against those three sources, and treat pressure to act before a deadline as a warning sign.

To avoid fake tokens, sites, and endpoints, check contract addresses and links only against official Whitechain and WhiteBIT sources. Confirm which chain an RPC endpoint serves with eth_chainId rather than trusting a hostname. Treat any RPC endpoint claiming to serve chain ID 1874 that is not the official one as unofficial. When in doubt, do nothing and ask in an official channel.
