# PySeedRecover
This is a Python script to recover a
[BIP-39](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki)
mnemonic seed phrase if words are missing, were written down in a wrong or
unknown order, or there is a typo in them, especially when used on the
Cardano crypto currency network.
This script will probably *not* help you, when you get an empty wallet
after restoring/importing with a seed phrase.
Since seed phrases contain a checksum, it is very unlikely to get to
another valid seed phrase (that opens an empty wallet) by wrong orders or
typos.
Empty wallets rather indicate that the restored/imported seed phrase is the
wrong one altogether – saved from a trial that was never really used or
something like that.
## Crypto Currency Disclaimer
I do not endorse the use of crypto currencies or the ecosystems built around
them, right now.
Proof-of-work networks like Bitcoin are ecologically harmful on an
unprecedented scale.
Proof-of-stake networks like Cardano do not have *that* problem, but still
have to prove their utility for real use cases.
Do *not* invest money that you cannot afford to *completely* lose into
crypto currencies (let alone NFTs and other strange tokens without any real
value)!
Their future is totally unclear.
The technology behind them is interesting, though.
And this script does explore a part of this technology (and hopefully helps
some people get their wallets back).
## Installation
You need a working Python 3 installation on your machine.
I do development on the newest stable version (3.10), but test it also on
the oldest
[still supported](https://devguide.python.org/#status-of-python-branches)
version (3.7).
Installation instructions for Windows can be found at:
[https://docs.microsoft.com/en-us/windows/python/beginners](https://docs.microsoft.com/en-us/windows/python/beginners)
(That guide links to Python 3.7, Python 3.10 can be found at
[https://www.microsoft.com/de-de/p/python-310/9pjpw5ldxlz5](https://www.microsoft.com/de-de/p/python-310/9pjpw5ldxlz5).)
For APT-based Linux distributions `apt install python3 python3-pip` should
be enough and for Arch-based Linux distributions `pacman -S python
python-pip` will install everything that is needed.
This script is then installed by `pip install PySeedRecover` (or `pip3
install PySeedRecover` if the standard Python on your operating system is
still Python 2).
After that, `seedrecover -h` should show you the usage information of the
script.
If for some reason `pip install`ed scripts are not on the path for
executables on your system and you do not want to bother what is wrong, it
can also be executed by `python -m seedrecover -h` (or `python3 -m
seedrecover -h` if Python 3 is not the standard on your system).
## Usage
```
usage: seedrecover [-h] [-w FILE] [-s EDIT DISTANCE] [-o]
[-l LENGTH] [-m POSITION [POSITION ...]]
[-a ADDRESS [ADDRESS ...]] [-k]
[WORD ...]
Recover Cardano seed phrases.
positional arguments:

options:
-h, --help show this help message and exit
-w FILE, --wordlist FILE
wordlist to use (default: english)
-s EDIT DISTANCE, --similar EDIT DISTANCE
try similar words up to edit distance
-o, --order try different orders of seed words
-l LENGTH, --length LENGTH
length of seed phrase
-m POSITION [POSITION ...], --missing POSITION [POSITION ...]

-a ADDRESS [ADDRESS ...], --address ADDRESS [ADDRESS ...]
check for stake addresses
-k, --koios check on koios.rest
```
> **WARNING:** If you give your (partial knowledge of your) seed phrase to
> this script on the command line, this information will be in the history
> of the shell you are using.
> It is also visible on screen and can perhaps be scrolled back.
> For security, clear the history and close the terminal after using this
> script.
We are using a test wallet that I generated with the following seed phrase:
```
ladder long kangaroo inherit unknown prize
else second enter addict mystery valve
riot attitude area blind fabric symbol
skill sunset goose shock gasp grape
```
The stake address for this test wallet is
`stake1u9t04dtwptk5776eluj6ruyd782k66npnf55tdrp6dvwnzs24r8yq`.
The simplest way to get something wrong are just small typos, some of which
may lead to other valid words, some of which not.
If we suspect that we did that, we can choose with the `-s`/`--similar`
option, up to which edit distance we want to search for valid seed phrases:
```
$ seedrecover -s 1 ladder long kangaroo inherit unknown price else second \
enter addict mystery valve riot altitude area blind fabric symbol skill \
sunset goose shock gap grape
ladder => ladder
long => long, song
kangaroo => kangaroo
inherit => inherit
unknown => unknown
price => price, pride, prize, rice
else => else
second => second
enter => enter
addict => addict
mystery => mystery
valve => valve
riot => riot
'altitude' not in wordlist!
altitude => attitude
area => area, arena
blind => bind, blind
fabric => fabric
symbol => symbol
skill => skill, skull, still
sunset => sunset
goose => goose
shock => shock, sock, stock
gap => gap, gas, gasp
grape => grace, grape
Length not set. Using smallest length for given phrase.

[…]
Seed phrases checked: 1_728 total, 8 fulfilled checksum, 8 without repetitions
```
`seedrecover` first reports, which words are gonna be checked for the given
words (due to `-s` and to words missing in the wordlist).
It then tells us, which total seed words length it is considering and how
many words are missing.
During the checking phase, progress and found stake addresses with their
seed phrases are reported.
If a word is missing from your seed phrase and you know, at which position
it is missing, you can give the position (or several possible positions)
with the `-m`/`--missing` option (as usual on Unix systems, the list of
options can be terminated with `--` to stop the list of positions and start
the list of known words of the seed phrase):
```
$ seedrecover -m 1 24 -- ladder long kangaroo inherit unknown prize else \
second enter addict mystery valve riot attitude area blind fabric symbol \
skill sunset goose shock gasp
ladder => ladder
[…]
gasp => gasp
Length not set. Using smallest length for given phrase.

[…]
Seed phrases checked: 4_096 total, 16 fulfilled checksum, 16 without repetitions
```
If you do not know, at which position a word is missing (or if several
words are missing), the possibilities become too many to manually check.
With `-a`/`--address`, we can give one or several stake addresses to search
for:
```
$ seedrecover -a stake1u9t04dtwptk5776eluj6ruyd782k66npnf55tdrp6dvwnzs24r8yq \
stake1u9vm3pq6f3a5hyvu4z80jyetuk8wt9kvdv648a6804zh0vscalg0n -- ladder long \

Seed phrases checked: 49_152 total, 195 fulfilled checksum, 195 without repetitions
```
This check already takes almost a minute, but it only gives us the searched
stake address and its seed phrase.
> **Note:** It is a good idea to give the stake addresses of all your
> wallets and accounts to `-a`.
> You never know if you mixed up the seed phrases and the one you are
> currently looking at is maybe for a different wallet than you think.
It is also possible to abbreviate the searched stake address(es) by `...` in
the middle:
```
$ seedrecover -a stake1u9...24r8yq stake1u9...calg0n -- ladder long \
kangaroo inherit unknown prize else second enter mystery valve riot \
attitude area blind fabric symbol skill sunset goose shock gasp grape
ladder => ladder
[...]

```
If the searched stake address is unknown, the stake addresses can be checked
via [koios.rest](https://koios.rest/) for previous activity.
```
$ seedrecover -k ladder long kangaroo inherit unknown prize else second \

goose shock gasp grape
ladder => ladder

Seed phrases checked: 49_152 total, 195 fulfilled checksum, 195 without repetitions
```
In this case, 195 requests to Koios were made.
This number will be much higher with more missing words or in combination
with other checks.
Koios does a rate limit of 100 requests per 10 seconds.
If you are unsure about the order, the `-o`/`--order` option allows to check
certain plausible reorderings (exchanges of rows and columns in a rectangular
notation of the seed phrase):
```
$ seedrecover -o -a stake1u9...24r8yq stake1u9...calg0n -- ladder else riot \
skill long second attitude sunset kangaroo enter area goose inherit \
addict blind shock unknown mystery fabric gasp prize valve symbol grape
ladder => ladder
[...]

Seed phrases checked: 23 total, 1 fulfilled checksum, 1 without repetitions
```
A check of all 24! = 6.2×10^23 permutations (for the 24 word seed phrase
case) is not feasible.
When combining the options (typos, missing worders, order), the number of
possible seed phrases explodes pretty quickly.
The search for a stake address can take hours or even days.
## Development
To set up a development environment for this project, just clone it, create
a virtual environment and install it with `pip` in editable mode.
```
$ git clone https://github.com/HeptaSean/PySeedRecover.git
$ cd PySeedRecover
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install -U pip setuptools wheel
$ pip install -e .
```
I am using `pydocstyle`, `pycodestyle` and `mypy` to lint my code and
`doctest` to test it with tests embedded in the docstrings.
The script `lint.sh` in the root of the project runs them all for
individual modules.
```
$ ./lint.sh seedrecover/<module>.py
```
The test with Python 3.7 is done using `pyenv`.
```
$ PYENV_VERSION="3.7.13" python -m venv /tmp/venv
$ source /tmp/venv/bin/activate
$ pip install -U pip setuptools wheel
$ pip install .
$ ./lint.sh seedrecover/<module>.py (for all modules)
$ (test invocations from README.md)
```
Upload to PyPI is done with `flit`.
```
$ flit publish
```
