In an ordinary non-test process, it attempts to execute an undeclared dynamically constructed module and suppresses execution in CI-like environments by exiting. - **Trigger:** Importing the package entry point in a non-test Node process. - **Impact:** Can execute code supplied by the dynamically resolved module and can terminate CI or sandboxed processes. - **Evidence paths:** dist/client.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-27T15:51:08.382Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time obfuscated dynamic module loading with environment-based anti-analysis termination. - **Attack narrative:** The public entry point imports client.js, which immediately calls initializeProvider. That function constructs an obscured package specifier, dynamically imports it only outside CI and test environments, and instantiates its export. The constructed module is not declared in package.json, so this is a concealed staged code-loading path rather than marketplace functionality. In CI-like environments it instead calls process.exit, which hinders automated inspection and disrupts consumers. - **Rationale:** The package contains an automatic, obfuscated, undeclared dynamic-import path plus environment-gated process termination. These behaviors are unrelated to the documented SDK and create a staged code-execution surface at import time. - **Files touched:** dist/client.js, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing the SDK automatically runs hidden provider initialization., The initializer dynamically imports an undeclared, obfuscated package name outside test and CI environments., The import-time code exits processes in CI or when USER is absent, an anti-analysis and availability-impacting action. - **Evidence against:** No package lifecycle install hook is present., The marketplace methods otherwise use the configured local JSON-RPC endpoint and explicit wallet actions., No concrete remote host, file harvesting, or exfiltration code is present in the package files. ## Public findings ### 1.
