Get aex9 transfers filtered by contractId and accountId

[CedrikNikita]

Currently in the wallet we have an assets list that contain all the aex9 tokens user have balance on (/v2/aex9/account-balances/${address}). Not sure about all the ways across aeternity universe of getting such tokens on users account, but main source is of course DEX. And we are searching for the way to show transactions only related to a particular address and particular token, with as less requests as possible.

Hey @CedrikNikita this is a new endpoint, we are moving things to /v3 (there will be a new yaml for it, sorry for the inconvenience).

You can use either sender or recipient param like

or

This two parameters making it harder to work with it. Because we are trying to show the user all the transactions related to a particular contractId. Now with two different parameters we would need to:

• make two requests in parallel instead of one
• merge this list together and sort them on our side
• remember both of the nexts and trying to make a logic which list of transaction is over (and we need to load more) on scrolling and which is not

Also without the decimals field we will not know how to present this amount field to the user.

I created separate issue for this: #1678
