Thought i would post this as i managed to get all my transactions from deadulus plus the staking rewards.
Firstly i added the deadulus wallet into koinly, then i went to deadulus mainnet… i had 2 wallets Legacy Byron and Shelly, i exported the transaction history from both and imported it into the Koinly wallet.
Then for staking i grabbed any one of my receiving addresses displayed in deadulus on the wallet that i had been staking on and headed over to pooltool.io.
from here i clicked on rewards data for taxes and entered my receiving address, which pulled up all my staking rewards with $ values for each epoch they were received!
bottom left off the page you can export the CSV, make sure you choose “CoinTracker.info (CSV) staking only”
then finally i imported this CSV to the deadulus wallet, and never even checked the tag as rewards option and BINGO everything is GOLDEN!
Hope this helps someone as it was driving me nuts thinking i would have to manually input the details.
