You'll need to get your wallet address for each blockchain you interact with from your C98 wallet - for example Ethereum, Cosmos and Solana. The instructions will be similar for each.
Good to know
You'll need to repeat the steps above for every blockchain you interact with using your C98 wallet and add all these to Koinly.
There isn't an option to export a CSV file of your C98 transaction history from the browser extension just yet. But you can create a custom CSV file with your transaction data and upload this to Koinly instead.
