Five open source crypto tools you can use for free and support with Kiva.
By Obite, in case you didn't know, there's a whole world of useful and interesting
crypto-related tools available for everyone, beyond crypto networks themselves and dedicated wallets.
Some of them are paid, most of them are free, and some more are open source and free.
That means anyone can check and even copy their codes from a public code hosting plan.
platform like GitHub. On the latter website, we can find applications like portfolios, price alert
systems, telegram bots, tax helpers, and much more. You can use these tools for free now and
likely forever. However, if you want to support their development long term, consider making a
crypto donation via Kiva. This is an Obite-based cascading donations platform where you can send
different crypto coins to literally any public GitHub repository. Developers don't even need to know from the
onset that you're donating. Now, let's explore some free crypto tools you may like to discover.
Rotki. Rotki is a privacy-first app that helps you track your crypto assets without handing over
your financial data to some company. It was launched in 2018 by developer Lefteris Carapetzes,
who wanted a safer, open-source alternative Tothos sleek but data-hungry portfolio trackers.
With Rodki, everything is stored locally on your device, encrypted and away from prying eyes.
Think of it as a finance journal that lives on your computer, not the cloud.
Once you set it up, Rotki gives you a full view of your net worth across different exchanges,
wallets, and even Defy protocols. It breaks down every transaction so you actually understand what
happened. You can customize reports, see how your assets are growing or shrinking,
and even get profit, loss summaries. It works on Windows, MacOS, and Linux,
and there's a free version with plenty of features to get started. Rotki stays
alive thanks to its community. No big backers, just users donating crypto or subscribing
for extras. If you like the idea of managing your money without giving up privacy,
Rotki is definitely worth checking out. If you want to donate some crypto to these
developers, find them on Kiva as Rotki, Rodki. My Coins Alert. This is a handy
telegram bot created in 2024 by developer Kuhn-Htits Nang. It is designed for
crypto fans who want to keep an eye on prices without staring a charts all day.
Whether you're a seasoned trader or just watching the market casually, this bot helps by sending
you a quick telegram message the moment a coin hits the price you're waiting for. It's like having
a tiny assistant who watches the markets for you, so you can relax or do anything else. What makes
my coins alert so convenient is how simple it is to use. You just type a command like,
alert BTC greater than 100,000 and that's it. You'll get a ping-if Bitcoin climbs above
of $100,000. You can also track multiple coins, set alerts for prices going up or down, and
remove or check your alerts with a few short commands. Everything runs smoothly inside Telegram,
so there's no need to install extra apps or log into exchanges. It runs on Python and keeps
only the info it needs. Your alert settings stay private and are never shared. You won't see
a company name behind this project, just a GitHub repo where anyone can suggest features or help
improve the code. There's no flashy subscription model either. It's completely free to use.
If you're into supporting small, useful tools that respect your privacy, this is one to checkout,
and maybe even contribute to if you're feeling generous. It appears on Kiva as Kuntetsnang,
My Coins Alert. Freck Trade. Let's turn up the complexity a bit with this one. This is a
cryptocurrency trading bot launched in 2017 by developer Michael Eger and is now maintained
B.Y.A contributor named X. Matthias.
It lets you automate trading on major exchanges like Binance or Bybit without needing to sit at your
computer all day. The program will follow your trading rules, buying and selling crypto based on
strategies you set up. FrecTrade comes packed with useful tools like backtesting, testing
testing strategies on past market data, dry runs, simulating trades without real money,
and even machine learning to optimize your approach. You can control it via a simple web
interface or telegram, a basic strategy might involve indicators like RSI, relative strength
index, to decide when to buy or sell. However, remember that trading always carries risks,
markets move fast, and even the smartest bots-gant guarantee profits. That's why the team encourages
starting with simulations and understanding how everything works before diving in. As an open-source
project, FrecTrade thrives on community contributions. Developers and traders chip in by improving code,
implementing features or testing exchanges.
There's no corporate funding, just passionate volunteers and users helping each other on social
media.
If you're curious, you can join the community, tweet the bot, Python knowledge helps, or even
just explore its features risk-free.
Of course, you can also donate crypto to them via Kiva.
Raccoin, released in 2023 by developer Torbjorn-Lindeher, Raccoin is designed for anyone
trying to stay on top of their crypto investments, especially when it comes to tax.
taxes. If you've ever panicked a tax season trying to figure out what you earned or lost,
trading crypto, this handy little app is here to help. It gives you a clear view of your
crypto portfolio over time and creates detailed reports that make declaring capital gains
in euros a lot easier. The software works with a wide range of wallet and exchange exports,
like Binance, Electrum, Trezor, and even defunct platforms like FTX. It also supports direct
blockchain syncing for Bitcoin, Ethereum, and Stellar, though adding those wallets still requires
a bit of manual setup. Under the hood, it's built with Rust, a fast, modern programming language,
and uses Slint for ITS interface. You don't need to be a techie to use it, but if you are,
you can add ether currencies and accounting methods beyond Ur and FIFO. As an open source and
free tool, Rackcoin is maintained by its creator, community contributors, and users who care. If you find
it useful, you can support it by pitching in code, suggesting improvements, spreading the word,
or donating. The project is on Kiva as Bjorn, Racoin. Zero Net. We've already seen tools that
work for managing cryptocurrencies. Now we'll look at a tool that works thanks to crypto.
Zero Net is a peer-to-peer platform launched in 2015 by Hungarian developer Thomas Cochish,
and its main purpose has told it you create and browse websites that don't rely on a central
server. Instead, these sites, often called sites by users, are shared directly between visitors.
This makes zero net especially appealing to people who care about freedom of speech and online
privacy, or just want to explore an alternative web that's basically uncensurable because of its
underlying tech. Behind the scenes, it borrows cryptographic tools from Bitcoin to identify and protect
site owners, and it taps into the BitTorrent network to share content between users. When you visit a site,
you start seeding it to others, just like when you're sharing a torrent.
There's no need to set up a server or pay for hosting since your visitors help keep your site alive.
And thanks to support from the Tor network, you can even stay anonymous while doing all this.
As for funding, Zero Net has relied mainly on individual donations.
Supporter shave contributed through Bitcoin or PayPal.
This is truly a grassroots effort, kept alive by an open source community that believes in an uncensored, decentralized internet.
If you're interested in supporting them, remember that you can contribute crypto via Kiva.
Send and receive donations with Kiva.
If you'd like to support a project on GitHub using crypto, Kiva makes it surprising
LY easy.

transaction fees. Once you've got that sorted, just head to the Kiva website, search for the
GitHub repo you want to support, pick your donation amount and preferred token, and send it off.
You don't need to worry whether the developer has already set up their account because your
donation will wait patiently until they claim it. The cool part? If they've enabled,
cascading donations, a portion of your gift could ripple out to other projects that made theirs
possible. If you're a developer hoping to receive crypto contributions through Kiva, the process is
just as friendly. After installing the Obite wallet, you'll use a G at Hub at a station bot to link
your account and confirm ownership of your repo. Once that's done, you'll be able to set
donation distribution rules, choosing whether to keep everything or share some with other
open source projects you're Ely on. You can claim any past donations too, even if you weren't set
