What is Whitechain

Whitechain is an EVM-compatible Layer 2 blockchain built on the OP Stack and powered by WhiteBIT, one of the largest centralized exchanges in Europe with more than 8 million active users. It settles on Ethereum via blob data availability and uses WBT (WhiteBIT Coin) as the native gas token.

As an OP Stack L2, Whitechain inherits Ethereum’s security guarantees while reducing transaction costs and latency for both end users and developers. The chain maintains full EVM compatibility, so any contract or toolchain that works on Ethereum works on Whitechain without modification.

Key technical details for developers:

1-second block time.
Flashblocks enabled: preconfirmations streamed about every 200 ms ahead of each full block.
A plain WBT transfer costs about 0.000105 WBT to execute at the 5 gwei base fee floor, well under one cent at $50 per WBT, plus the L1 data fee.
Fees paid in WBT, the native asset of Whitechain with utility across the WhiteBIT ecosystem.
The L2 architecture nets sequencer margins against Ethereum blob costs, keeping fees structurally low at scale.

Whitechain Roadmap

Q1–Q2 2026 | Foundation & Core Engine

Establishing high-throughput OP Stack architecture and core network stability.

OP Stack L2 Devnet Deployment. Engineered high-speed L2 execution with WBT integrated natively as the gas token.
Battle-Tested Infrastructure. Established internal testnet nodes, real-time telemetry, and proactive security monitoring.
Early Builder Cohort. Onboarded initial core protocols and smart contract infrastructure partners.

Q3 2026 | Public Acceleration & Developer Initiative

Opening public access, Builders Program, and growth initiatives.

Public Testnet Open to All. Deploy and test on Whitechain Sepolia (Chain ID: 1874).
Builders Program is Live. Empower the next generation of on-chain products to scale their vision with milestone-based capital, engineering support, and built-in distribution reach across WhiteBIT's 5M+ user ecosystem.
AI-Native Developer Tooling. Integrated llms.txt and Claude Code skills for rapid prompt-to-deployment workflows.
Explorer. Live testnet canonical bridge and Blockscout block explorer verification.
More things on the way

Q4 2026 | Mainnet Genesis & Distribution Platform

Production deployment, zero-friction WBT state migration, and streamlined user distribution reach.

Public Mainnet Launch. WBT officially transitions as the native L2 gas token with dynamic EIP-1559 execution and UX upgrades.
Unified Distribution Platform. Social layer, dApps, and seamless connectivity across the WhiteBIT Platform and W Group.
Automated Balance Continuity. Passive state snapshot ensuring WBT holders transition with no action required.
Genesis dApp Ecosystem. Flagship DeFi and infrastructure protocols targeted to go live on day one.
Rails. Simplified UX through a single platform across the ecosystem
