• Scalability — some cryptocurrency users, such as algorithmic traders, accumulate millions of transactions per year. CoinTracker needs to work seamlessly for those power crypto traders.

• Blockchain — whether it's running our own nodes, implementing xPub address generation and traversal, or parsing smart contracts to seamlessly support decentralized trading, we get our hands dirty with core blockchain technology

• Technical complexity — integrating with hundreds of exchanges and blockchains and supporting thousands of cryptocurrencies means we have to methodically architect our software and build critical monitoring systems to deliver a robust and accurate platform

• Product challenges — building a consumer finance product that works flawlessly for our global user base and through our partner integrations with top crypto exchanges, marketplaces, and tax-filing software

Our tech stack is

• Web: Typescript, React, Styled-Components, Astro
