Whitechain Relaunches as Ethereum L2 on OP Stack, Keeping WBT as Gas Token

Whitechain has migrated to an Ethereum Layer 2 built on Optimism's OP Stack, with WhiteBIT Coin (WBT) retained as the native gas token and the sequencer operated by the WhiteBIT exchange at launch. The settlement path runs through Ethereum via blob data availability, according to Whitechain's own documentation, and the migration copied existing balances to the wei.

The configuration is deliberately self-managed. Optimism states that under this model Whitechain operates its own chain, retains control of its configuration, and coordinates its public repositories and configuration files. The OP Stack itself is open-source and MIT-licensed, which means Whitechain inherits no proprietary lock-in but also assumes responsibility for the operational load that comes with running chain infrastructure. Optimism notes that Whitechain joins a growing group of exchange-backed chains building on the stack — a cohort that now anchors a meaningful share of Ethereum's Layer 2 throughput.

How gas and token economics work after the move

Gas is paid in WBT under EIP-1559 with OP Stack parameters. That is a structural choice, not a cosmetic one: base fees are burned according to the standard EIP-1559 mechanism, and priority fees flow to the sequencer — which, at launch, is WhiteBIT itself. The project states that WBT remains the same token with the same supply after the migration. No reissuance, no new deployment, no redenomination.

For exchanges and token issuers, this is the detail that matters. Keeping WBT as the gas asset preserves the token's utility surface — every transaction on the chain creates demand for it — while the EIP-1559 burn introduces a deflationary pressure valve calibrated by usage. The token does not change; the environment around it does.

What does this change for users?

After the mainnet launch, WhiteBIT users will be able to withdraw WBT directly to Whitechain L2 from the exchange interface, with no third-party bridge. That removes the most common failure point in L2 onboarding — bridge contracts have historically been among the most exploited components in the sector. Direct exchange-to-L2 withdrawal shortens the path from custody to on-chain use to a single step.

The migration itself was engineered for continuity: balances were copied to the wei, meaning users hold the exact same amounts, at the exact same precision, on the new network.

Background and group context

Whitechain first announced the move in August, framing the relaunch as a distribution-focused Ethereum L2 network within W Group, the structure that also contains the WhiteBIT exchange. A public testnet has been reachable since August 18, 2026, giving the team a runway for validation before mainnet.

The scale of the distribution surface is substantial. Optimism says W Group serves more than 40 million customers globally across WhiteBIT, Whitepay, white.market and Whitewallet. For context, that is a user base larger than most standalone L2 ecosystems can reach through organic onboarding — and each of those customers is a potential direct withdrawer to the new chain.

Whitechain's migration documentation also notes a strategic rationale: the OP Stack is the base for Base, Optimism and the wider Superchain. Building on it buys shared tooling, a tested codebase, and a defined path toward decentralized sequencing — the eventual step of removing the single-operator sequencer model that WhiteBIT currently holds.

What comes next

The public mainnet launch will be the first test of how the new infrastructure performs with real users and applications. Testnet activity, however extensive, cannot fully simulate production load, and the quality of that launch will determine whether the exchange's distribution advantage converts into sustained on-chain activity.
