Cake Wallet Rolls Out Self-Custodial Lightning Support

Cake Wallet has integrated the Lightning Network into its mobile privacy wallet, after years of holding back over custody and usability concerns.

Lightning has long promised fast, low-cost Bitcoin payments. For many users, that promise came with tradeoffs. Self-custodial setups required channel management, liquidity planning, and consistent uptime. Easier options often relied on custodial structures. Cake Wallet chose not to add Lightning until it could avoid that compromise.

The new integration relies on the Breez SDK and Spark, a Bitcoin layer two network designed to work alongside Lightning. According to the company, this architecture removes the need for users to manage channels or maintain constant online presence. Funds remain self-custodial, with an on-chain exit available at any time.

Vikrant Sharma, CEO of Cake Labs, addressed the delay in a statement:

“Lightning has always been powerful, but the user experience forced people into a choice between convenience and sovereignty, we were not willing to ask our users to make that tradeoff.” He added, “We waited until we could deliver Lightning in a way that aligned with our core principles: privacy, self-custody, and long-term user sovereignty. Now, with Breez and Spark, Lightning finally reaches a point where it can be fast and intuitive without turning bitcoin into an IOU or giving up control. This is the first time Lightning felt aligned with the principles Cake was built on.”

Privacy defaults built into Lightning

Cake Wallet positioned privacy as central to the release. The wallet does not embed Spark addresses in Lightning invoices. It also does not publish Spark transaction data to public Spark explorers by default.

In a press release, the company stated:

“Lightning transactions in Cake Wallet do not embed your Spark address in Lightning invoices, and transaction data is not published to public explorers by default. Visibility is intentionally limited, reducing unnecessary exposure of user activity and safeguarding user privacy.”

Seth for Privacy, COO of Cake Wallet, framed the design philosophy in direct terms:

“Lightning should not require users to sacrifice privacy or custody just to get speed.” He added, “What we have today makes Lightning practical with solid privacy defaults, simple self custody, and a clear on chain exit.”

Cake described its Spark privacy model as closer to a VPN than a public ledger. Users do not need to adjust settings to preserve privacy. The wallet applies those defaults automatically.

Human-readable Lightning addresses from day one

The update introduces custom Lightning addresses that function like email addresses. Users can claim an @cake.cash username and receive payments without sending individual invoices each time.

Cake Wallet allows address creation without minimum balances or usage thresholds. The company stated that users can begin receiving payments immediately, without waiting to unlock features.

Under the hood, Lightning addresses translate into payment requests. From the user perspective, the process appears consistent and straightforward.

Advanced Bitcoin tools in a single app

Cake Wallet had already adopted Bitcoin-specific technologies that many multi-coin wallets have not implemented. These include Silent Payments and Payjoin, both designed to reduce address reuse and transaction traceability.

The Lightning integration places Cake among a small group of wallets that combine fast payments with self-custody and privacy controls.

The app also supports a broad range of hardware wallets. Users can move funds between cold storage and Lightning balances within the same interface. The update reduces the need for multiple applications to manage long-term storage, on-chain transactions and daily Lightning use.

Lightning swaps and real-world spending

The integration expands beyond payments. Users can swap from a Lightning Bitcoin balance to assets such as USDT in Ethereum or Tron wallets within seconds, according to the company. Cake Wallet described this as useful for remittances and merchant payments.

Lightning now connects directly to Cake Pay, the company’s debit and gift card service. Users can purchase prepaid debit cards or gift cards from within the app using native Lightning transactions. The company plans to add full in-app gift card code delivery in a future update.

Recent releases also introduced Birdpay, which allows users to send crypto to X.com usernames, and support for xStocks tokenized equities.

A shift after years of caution

Cake Wallet has operated since 2018 and reports more than one million users. The company delayed Lightning integration for years due to concerns over custody and complexity. The new release marks a shift in that stance.

The wallet’s leadership argues that Spark and Breez removed the earlier friction points. Users no longer need to manage inbound liquidity or maintain a Lightning node.

The launch reflects a broader effort within Bitcoin development to balance speed with user control. Cake Wallet positions this update as proof that self-custodial Lightning can function in a consumer mobile app without hidden tradeoffs.
