A majority of the time if you want to access a BTC wallet you have to use apps or websites developed by others. Of course 9 times out of 10 these sites/apps are very reliable and trustworthy but there's always an inherent risk in using things where you can't see the back end.
Python is a coding language that is incredibly accessible and this makes it the perfect platform to access your wallet without needing to seek 3rd party providers. I intend to showcase Python's abilities for crypto and provide practical examples using two Python libraries: bit and bitcoinlib.
Why would you want to access your BTC wallet in Python?
The key reasons I can think of are convenience, customisation and security however I'm sure there are many other reasons to access your crypto via python.
Convenience - I admit, initially writing the code to access a crypto wallet is a bit tedious until its exactly how you want it, but once it is then you have your own source code to access your crypto. No faffing with 2FA, no concerns about clicking a scam website instead of the real thing, instead you have a file on your laptop and thats that.
Customisation - with python code you can look at past transactions, format it into a reportable format (eg for tax reasons) and be able to obtain a convenient overview of your past transactions. This is very useful as its difficult to reach high levels of customisation on individual programs; most crypto reports would require multiple programs and websites.
Security - By owning your own access to your wallet (ie not using third person access), cookies or other internet tracking will not be able to link you to crypto sites. You would be completely anonymous to marketing. This makes you significantly less of a target as people don't target what they don't know you own.
So really theres plenty of reasons to create the access to your wallet. Below I will demonstrate the code to access your wallet, but this is just the basic starting code. With research and practice you can replicate it with additional security features and customise however you like.
Bit
Bit is one of the simplest crypto libraries and its possible to import your wallet using your private key using the below code.
These 5 lines are all you need to access your wallet. From there you can send transactions, sign transactions, generate QR codes and access testnet.
Bitcoinlib
Bitcoinlib is very similar, enabling you to generate or unlock your wallet within python, send transactions and generate QR codes. Below you can see the code used to start off and access you wallet using your private key in Wallet Import Format (this can be altered)
The risks
I could blindly spout out the benefits of this and ignore the risks but as with anything digital its important to acknowledge the risks.
Security Concerns - Storing private keys in scripts or applications may expose them to security threats. Your device should be secure if using code like this, free from key loggers and viruses. A code as sensitive as this should be on a device with no affiliation with crypto and that will not attempt to access crypto sites.
Transaction Errors - Automating transactions increases the risk of errors. When sending crypto its good practice to double check the address however automation without appropriate checks increases the risk of errors and in crypto, an error such as mis-sent funds can be devastating.
Conclusion
Ultimately, the apps and websites we use to access crypto are generally trustworthy however it you do want to own the code to your own crypto storage the starting blocks are above. The codes can very easily be customised to accommodate passphrases or seed words, just do your research and you'll be fine.
