Recently in March, Koinly integrated support for Cardano Native Takens. These tokens are very similar to native tokens for Ergo, both projects utilize eutxo and native tokens.
I am pushing for more ergo wallets to have an export public key feature that would allows seamless integration into your platform in a way similar to the way you have Eternl wallet (CCvault) integrated. Currently Yoroi supports export of public keys so this should be no issue to implement for other ergo wallets as well.
This would be a huge step forward for Ergo community and Koinly users. Thanks!
