Filing Your 2025 Crypto Taxes: Forms and Gotchas

Step-by-step walkthroughs for sending, receiving, swapping, staking, and recovery.
Crypto is operational. Unlike a bank app where mistakes can be reversed by a support ticket, on-chain actions settle the moment you press confirm — and the order you click the buttons matters. Sending to the wrong address, signing the wrong transaction, or restoring a seed into the wrong wallet type can cost you real money.
These walkthroughs exist so you don't have to guess. Each one is a short, focused tutorial with the exact button order, the screens to expect, and the checks to run before you confirm anything irreversible.
The library is still growing. Planned guides cover first-time wallet setup, seed phrase backup done properly, sending and receiving across different chains, in-app swaps, staking flows, hardware wallet integration, and account recovery on a new device. If you have a wallet and a specific task to do, this is the section that gets you from opened-app to done.
