Hi there 👋

This tutorial shows you how to retrieve your transactions from the Zapper wallet aggregator.
​
​Step 1: Login to Zapper

- Go to "History".

- Click on "Download CSV".

💡 You have to click on each "little icon" (Ethereum, BSC, Polygon and Fantom) and upload one CSV per chain

Step 2: On Waltio

- Go to "Others"

- Click on Zap

- Upload the previously obtained CSVs

💡 Holding non-custodial wallets (Ledger, Trezor, Metamask etc... type) does not require reporting. Only accounts held abroad (exchange platforms such as Coinbase, Kraken, etc...) must be declared via the 3916-BIS form.

⚠️ If you have imported transactions from a public key on Waltio and a file from Ledger Live, there is a good chance that some transactions are present in both transaction histories! This will create duplicates (easily identifiable by looking at your inventory record) that you will need to manually delete in order for your capital gains calculation to be correct.

If you have any other questions, do not hesitate to contact us via the chat just at the bottom right of your screen! 💬
