Whitechain is more than an EVM-compatible Layer 2. It is the on-chain layer of the WhiteBIT ecosystem, with deep integration into a centralized exchange that serves more than 5 million active users. For project teams considering where to deploy, that integration is the difference between launching into a generic L2 environment and launching into an environment with built-in distribution, liquidity, and a defined path to an exchange listing. This page is for BD leads, founders, and integration teams evaluating Whitechain as a deployment target.

​
What you get with Whitechain

​
Distribution at the chain layer

WhiteBIT is one of the largest centralized exchanges in Europe, with more than 5 million active users. Whitechain is the chain those users interact with when they hold or use WBT, which gives projects on Whitechain a measurable head start over chains where user acquisition has to be built from scratch.

​
Direct exchange withdrawal to L2

After Mainnet launch, WhiteBIT users will withdraw WBT directly to Whitechain L2 from the exchange UI. There is no third-party bridge in the middle of that path, and the same withdrawal flow already exists today for the legacy Whitechain L1. This means new users land on Whitechain with WBT in their wallet through the exchange flow they already use.

​
Listing and co-marketing pathway

Projects on Whitechain have a defined path to:
  • WhiteBIT exchange listing. Tokens that meet the listing criteria can be considered for the WhiteBIT order books, opening centralized-exchange liquidity to your users.
  • Joint announcements. Significant integrations and product launches on Whitechain are eligible for joint communication across WhiteBIT and Whitechain channels, including the Whitechain blog and social channels.
The exact criteria, scope, and process are agreed per partnership. The path is not automatic, it is a structured engagement.

​
Whitechain Foundation Grants

The Whitechain Foundation runs a Grants Program with financial, marketing, and technical support for projects building on Whitechain. Grants are distributed via vesting rather than lump sums, which aligns funding with delivery milestones. Details on the Whitechain Grants Program.

​
Technical foundations

The partnership value sits on top of a standard OP Stack technical floor:
  • EVM-compatible Layer 2 on the OP Stack, settling on Ethereum via blob data availability
  • 1-second block times with Flashblocks (100 to 200 ms)
  • Transaction fees as low as $0.001, paid in WBT
  • Full EVM compatibility, deploy with Hardhat, Foundry, or any Ethereum toolchain
  • Canonical bridge to Ethereum for asset and message transfer
For the network parameters and endpoints, see Network reference.

​
First-party products on chain

Whitechain ships with a small set of first-party products that signal the ecosystem is active from day one:
  • Whitechain Portal. First-party bridge for moving assets between Ethereum and Whitechain.
  • WhiteSwap. First-party DEX for swaps and liquidity on Whitechain.
  • Block Explorer. Production-grade Blockscout-based explorer.
These products work as integration surfaces for partner projects: list pools on WhiteSwap, route bridge flows through Portal, surface contract activity on the explorer.

​
Who is the typical partner

Whitechain is most useful to projects that:
  • Want exposure to a large, existing crypto user base without rebuilding distribution
  • Need a low-cost, EVM-compatible L2 for high-volume application logic
  • Care about a clear path from on-chain product to centralized-exchange listing
  • Value being part of a focused ecosystem rather than one of many on a generic chain
Common partner profiles include DEXs, lending protocols, NFT platforms, prediction markets, games, and consumer dapps with payment flows.

How to engage

  1. Review the docs. Start with Introduction and Network reference to confirm Whitechain fits your technical requirements.
  2. Apply for a grant if your project qualifies. Whitechain Grants Program.
  3. Reach out via the Discord community for general partnership inquiries.
  4. Build and launch. Deploy on Whitechain Testnet (chain ID 1874) and migrate to Mainnet at launch.
