Data and Analytics Infrastructure for Crypto Tax & Accounting Systems
The Biggest Challenge in Crypto Transactions: Accurate and Consistent Data
In the world of crypto, one of the most complex problems is tax calculation and accounting.
Users trade across multiple exchanges, in hundreds of pairs, with thousands of transactions — each with different timestamps, price levels, and fee structures.
atWallets does not provide tax or accounting services.
Instead, we supply the infrastructure that crypto tax and accounting platforms need to obtain accurate, consistent, and secure data.
Put simply, we are the data engine behind crypto tax systems.
