Spark wallet review · checked 2026-09-11
Cake Wallet and Spark
Cake Wallet is included in this review of wallets and wallet surfaces that use, expose, or publicly describe Spark. The question tested here was whether the reviewed product provides a complete in-app unilateral-exit workflow when Spark operators are unavailable.
Review result
No complete in-app exit flow found
Cake v6.4.4 and the current source pin Breez Flutter 0.23.0. The earlier statement that this wallet still used 0.14.0 is obsolete. The reviewed Lightning adapter calls ordinary SDK payments and deposit refunds, but no current exit-state export or complete operatorless recovery workflow was found.
Surface reviewed: public mobile source
Release or source boundary: Cake v6.4.4 (September 4) release source and current default branch were reviewed. The Lightning adapter and SDK declaration are identical.
What the review found
mnemonic or seed initialization Spark, Lightning, and cooperative Bitcoin-address payments upgraded Breez 0.23.0 dependency with SDK exit construction and state export/import capabilities
What this does not establish
This is a dated, bounded review of the named source, release or public documentation. It does not establish that every version behaves identically, that a private implementation has no recovery path, or that protocol-level unilateral exit is impossible. A partial SDK capability, seed backup or cooperative withdrawal is not counted as a complete operatorless mobile recovery flow.
Evidence and limits
- The public Cake article describes a protocol-level response to an attack; it does not expressly claim that the audited UI contains an exit button.
- The result is limited to the pinned Cake tree and its pinned dependency.
