Recap currently provides automated wallet support for several blockchains.
All other wallets can be added as a Custom Account with CSV data import.
In "Accounts" select the "Add Account" button.
Select "Custom Account" and then next.
Give the account a name and click "Next" - you'll see a custom account has been created and is ready to fill.
To add data, click the cog in the bottom right of your custom account and choose "Import Recap CSV".
Click "Browse" to locate and select your CSV file and hit "Import".
