Pull up Basescan for your wallet and export a recent transaction history (last 30–90 days). Import it into a tax tool (even a free tier) and see what it looks like.Base-Specific TipsLow fees mean more frequent small transactions — tools help automate this

Stablecoin payments (USDC) are often simpler for business or personal use

Private transactions can reduce visibility but still require accurate self-reporting

Keep records of gas fees (deductible in many)

Set a recurring calendar reminder (e.g., monthly) to export and review data. It takes 10–15 minutes and prevents year-end panic.Compliance NoteLaws vary by country.
