Cosmostation has released the new Mintscan API: https://docs.cosmostation.io/apis
Could Koinly use the API to support all of the available Cosmos Ecosystem chains? Currently around 10 chains are supported, but more are likely to come up soon, since Mintscan explorer itself support 59 chains.
I think it would be wise to build one unified way of getting the transaction data for all Cosmos Ecosystem chains and not build separate integrations using different block explorers.
