2020 was a pretty big intro year for Elrond blockchain. First they issued ERC20 tokens on Ethereum, then swapped them for EGLD on their native chain at 1:1000 ratio. Some of the swaps were done with their own bridge, others by CEXes.
This results in quite a mess of ERD token movements (getting “withdrawn” to one-off bridge addresses), and right now Koinly doesn’t support native Elrond wallet imports, so all the EGLD end needs to be entered manually. Which becomes painful because there is a staking reward there every few days.
Would be great to add native support for Elrond wallet imports: Elrond Explorer
