Spark wallet review · checked 2026-09-11
Layerz Wallet and Spark
Layerz 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
Layerz implements a polished flow named Spark Exit, but its own types specify that the SDK withdraw call is followed by the SSP signing and broadcasting the L1 transaction. It is a cooperative withdrawal, not the defined operatorless exit workflow.
Surface reviewed: public multiplatform source and developer preview release
Release or source boundary: Latest listed GitHub release remains v1.6.0 (July 20). This review inspects the newer default-branch source; it does not claim that those commits are in the published binaries.
What the review found
fee-quoted and resumable cooperative Spark withdrawal persistent tracking of the SSP cooperative-exit request ordinary Spark wallet operations across several interfaces
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
- Layerz labels itself a developer preview, so it is not represented as a mature production wallet.
- The zero canonical-term count is not the basis for classification; the manually reviewed implementation explicitly identifies an SSP cooperative-exit request.
- A later Layerz release could add a separate unilateral executor.
