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. See Transaction finality.
  • 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. See Network fees.
  • 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.

What makes Whitechain different

Whitechain is part of the broader WhiteBIT ecosystem. That alignment unlocks four things uncommon among Layer 2s:
  • Listing and co-marketing pathway is part of the product. Projects that meet the criteria have a defined route from on-chain deployment to WhiteBIT exchange listing and to joint announcements across WhiteBIT and Whitechain channels. Those channels reach the more than 35 million users of W Group, the fintech group behind Whitechain. On most chains, this path does not exist as a structured offer.
  • The gas token is the exchange token. WBT is used to pay fees on Whitechain and to access utility on WhiteBIT. A single asset carries two demand loops, which strengthens the economic case for projects denominated in WBT.
  • Direct exchange-to-L2 withdrawal. Once Mainnet launches, WhiteBIT users will withdraw WBT directly to Whitechain L2 from the exchange UI, with no third-party bridge in between.
  • European focus. WhiteBIT is one of the largest centralized exchanges in Europe. Whitechain inherits that geographic distribution.
