If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package advertises itself as a wallet library but ships a 67-byte no-op index.js; the entire payload is a preinstall lifecycle script that fires automatically on npm install. The script iterates process.env and selects variables whose names contain any of a broad credential-related substring list (key, secret, token, pass, mnemonic, seed, private, wallet, api, rpc, infura, alchemy, supabase, database, deploy, vercel, railway, tron, contract, env, url), then bundles the matched values together with the machine hostname, current working directory, and Node.js version and POSTs the JSON to a hardcoded remote endpoint. The destination host is written as the 32-bit integer 759017974, which decodes to 45.61.177.246, and the request targets port 61289 with a per-victim GUID-shaped path. The integer-encoded host defeats plain-text URL scanning and there is no documented functionality that would justify the outbound POST.
