Puzzle Sweep

front-running-proof cash-out · MARA Slipstream
PUBLIC · testing only

Two tools, two pages, one process — one file (app.py) that runs identically online (for testing) and offline (for the real signing). The wallet generator creates a fresh BIP39 / BIP84 destination wallet. The signer takes a private key + UTXOs and produces a raw signed transaction you can paste into slipstream.mara.com without ever exposing the public key to the public mempool.

You are on the public deployment. This is for testing the flow and the code paths. Do NOT submit a real puzzle private key here. For the real signing run, clone this repo onto an air-gapped machine and run python app.py -- the cryptography is the exact same code paths you are testing right now.
