Delta

Delta is a hosted portfolio tracker for crypto and other investments. A single login synchronizes portfolio data between web and mobile devices, while connection setup is organized around the individual portfolio that receives an exchange or wallet account.

One login can hold several separately configured portfolios

Each Delta portfolio can receive exchange and wallet connections. Exchange setup uses API credentials or, for some venues, a direct authorization login, and asks for an import timeframe and settings. Wallet tracking can use a public address or xpub, with direct connection options including MetaMask, eToro Money and WalletConnect.

A setup can import complete available history, history after a chosen date, only new transactions or balances only; it can also include or exclude deposits and withdrawals. Wallet setup likewise uses a timeframe and can import NFTs where the connection supports them. Manual transactions and CSV uploads provide a way to represent unsupported or missing activity.

Cloud portfolio sync does not sync exchange credentials

Imported trades synchronize between Delta devices, but exchange API credentials stay on the local device rather than being copied to every device under the login. The account model therefore shares the portfolio record while retaining a device-level boundary around those credentials.

Free access permits up to two exchange accounts or two wallet connections. Delta PRO unlocks unlimited exchange and wallet connections and can notify users about newly imported activity; PRO+ can unlock unlimited active portfolios. Performance, history, metrics and price or real-time alerts all depend on the activity actually represented in the selected portfolio.

Delta vs rotki: hosted sync and source-history limits

Exchange APIs may omit or inadequately represent margin and short activity, staking and farming rewards, airdrops, delisted assets, conversions, stop-limit orders, referral bonuses or sub-account trades. Some venues also limit the retrievable historical range, so selecting complete history cannot retrieve records outside the exchange API’s available window. Wallets with more than 10,000 historical transactions are rejected for performance reasons.

If imported exchange history does not reconcile with a current balance, Delta can create a balance-adjustment transaction with zero cost basis because the original acquisition is unknown. Delta is thus the hosted, multi-device alternative to rotki, but neither a successful sync nor a balance adjustment replaces complete source history and transaction review.
