Whitechain Moves to Ethereum Layer 2 on Optimism’s OP Stack, Keeping WBT as Gas Token
Beneath the brand new design, the OP Stack sequencer is operated by WhiteBIT at launch, and fuel is paid in WBT underneath EIP-1559 with OP Stack parameters.
The migration copies balances to the wei.
Optimism says that underneath the self-managed mannequin,
Whitechain operates its personal chain, retains management of its configuration, and can coordinate its public repositories and configuration recordsdata.
The OP Stack is open-source and MIT-licensed, and Optimism notes that Whitechain joins a rising group of exchange-backed chains constructing on it.
Whitechain’s documentation states that the community is
settled on Ethereum through blob knowledge availability, with WBT (WhiteBIT Coin) because the native fuel token.
The venture says WBT stays the identical token with the identical provide after the transfer.
After mainnet launch, WhiteBIT customers are resulting from withdraw WBT on to Whitechain L2 from the alternate interface, with no third-party bridge.
Background to the Migration
The transfer was first introduced in August.
Whitechain mentioned it could relaunch as a distribution-focused Ethereum L2 community on the OP Stack, as a part of W Group, which additionally contains the WhiteBIT alternate.
A public testnet has been reachable since August 18, 2026.
Optimism says W Group serves
greater than 40 million clients globally throughout WhiteBIT, Whitepay, white.market and Whitewallet.
In its migration documentation, Whitechain notes that
the OP Stack can also be the bottom for Base, Optimism and the broader Superchain, giving it shared tooling and a path towards decentralized sequencing.
The general public mainnet launch would be the first check of how the brand new infrastructure performs with actual customers and functions.
