Crypto exchange WhiteBIT has integrated the Bitcoin Lightning Network, enabling deposits and withdrawals over the second-layer payment channel system, the company announced on Thursday, October 8, 2026.

The rollout, powered by Bitcoin infrastructure provider Voltage, carries a 0.25% deposit fee and a 0.15% withdrawal fee, according to the exchange's official announcement. Users can transact via QR code or standard payment details.

WhiteBIT, headquartered in Zug, Switzerland, ranks as the 17th-largest exchange by transaction volume, according to CoinGecko data.

What does the integration actually change?

For WhiteBIT customers, the change is operational rather than cosmetic. Bitcoin movements that previously settled on the base chain — with its confirmation times and variable fee market — can now route through Lightning's channel-based architecture. The exchange said the launch supports use cases including:

• Remittances
• Exchange account funding
• Merchant-style QR payments
• Interoperability with Lightning-enabled wallets and applications

The network also carries a privacy dimension. Because Lightning payments settle off-chain rather than being recorded individually on Bitcoin's public ledger, they are harder to trace than standard on-chain transactions.

"WhiteBIT's mission is to make blockchain technology accessible and widely adopted by delivering practical, user-friendly solutions for digital assets," Founder and CEO Volodymyr Nosov said in a statement.

"Adding Lightning support brings us closer to this goal as we are making Bitcoin faster and more useful for customers who want to top up accounts, send and receive funds, and use Bitcoin across more real-world flows," Nosov added.

Why are exchanges turning to Lightning?

WhiteBIT is joining an established trend rather than starting one. Coinbase and Kraken, two of the largest exchanges in the market, integrated the second-layer solution in recent years. The operational logic is straightforward: Lightning moves funds faster and at lower cost than base-layer Bitcoin, which matters for exchanges rebalancing inventory across venues and for users funding trading accounts.

That dynamic shows in the data. Transaction volume on Lightning has surged this year, driven largely by exchanges using the network to move funds.

The network's profile has shifted considerably since its 2018 launch. Early adoption centered on small-value payments — tipping, buying a cup of coffee — as advocates pitched Lightning as a tool for everyday microtransactions.

Today the growth driver is institutional: exchange flows, remittances and payment rails where speed and fee certainty outweigh the visibility of an on-chain record.

What comes next?

Voltage's role as infrastructure provider signals how exchange Lightning integrations are typically delivered now: rather than each venue operating its own node infrastructure in-house, specialized providers supply the channel management and liquidity layer. That model lowers the operational barrier for mid-sized exchanges considering similar deployments.

For WhiteBIT, the integration adds a second Bitcoin rail alongside its existing base-chain deposits and withdrawals. Whether Lightning flows grow into a meaningful share of the exchange's Bitcoin volume will depend on user adoption — but the exchange now has the plumbing in place to capture the segment of Bitcoin users who transact primarily over Lightning-enabled wallets and applications.
