Monero Seed Validator

Check a Monero seed / mnemonic offline — no node, no explorer, no trust, no third party.

Why bother

You wrote your 25 words down. Before that wallet ever holds a cent, you want to know the phrase is real and restores the address you think it does. One typo in any of the 24 data words flips the checksum word, so a bad phrase is caught by a proper validator instead of silently rebuilding the wrong wallet. This tool runs entirely on your machine.

Run it

pip install monero==1.1.1
python seed_validate.py "technical ladder upkeep knapsack ... weird"
# confirm it restores a known address (copy-check):
python seed_validate.py "..." --expected 44JRGs...BagrPHPePoZ5

22-test suite: python -m pytest test_seed_validate.py -q. Free, MIT, no backend.
