The package presents itself as a Node.js cryptography helper and depends on ethers, encouraging callers to pass cryptographic or wallet material to its sole exported async function. That function forwards the caller's argument via axios to an APIBASEURL assembled at runtime from ~13 fragments produced by an obfuscator.io RC4 string-array decoder. The entire ~30 KB index.js is wrapped in the standard obfuscator.io scheme (RC4+base64 string array, hex-escaped literals, wrapped index accessors, array-rotation IIFE, and a self-defending RegExp function-body anti-tamper check) whose only purpose here is to hide the destination URL. The caller does not configure this destination and is not informed of it; normal use of the advertised API silently leaks the caller's cryptographic inputs to an author-controlled host.
