We're proud to announce our new partnership with CoinRabbit, a crypto asset management platform with loan, earn, trade and save services whose users often engage in on-chain activity that can carry tax implications.


Feature Spotlight: Lock Periods
Lock Periods lets you freeze past tax years while safely optimizing current ones. Lock historical data, experiment with accounting methods, and improve tax outcomes without risking previously filed reports.


Product Update: Aster DEX and Sei support now live
Summ now supports Aster DEX and the Sei network, making it easier to import perpetual, spot, and on-chain transactions for accurate crypto tax reporting. Connect via API, wallet address, or CSV to simplify your crypto tax calculations and reduce manual tracking.


Product Update: Spam Filtering
Our new spam center gives you control over any crypto spam currencies that slip through automated detection. Mark entire currencies as spam in one click, manage all spam controls centrally, and maintain clean transaction data for precise reports.
