Did some brief testing and for those few tests, it seems to work great. Some points to note:

• I'm getting a bit lower Fees on this PR, which is great.
• On this swap the decimal seemed truncated on the fiat display for the input amount:
• (LEFT is this PR <---> RIGHT is production)

LGTM

Only thing that I noticed is that sometimes theres a 533 response from paraswap

That's probably just rounding as I believe the same display logic is on prod and dev

Hmm I think the screenshots I shared aren't the right ones 🤔 . I was referring to seeing a truncated fiat value for the input field, looking something like '$342324.'

I guess it looked weird to me seeing a number truncated ending with a dot/decimal. But can't reproduce for now...

this might be reported in #1316

LGTM!
This affects only mainnet right, as paraswap doesn't operate on xDai or Rinkeby?

Only the issues reported before( #1426 #1427 ) are present in this PR

Yes @elena-zh that's it.

@biocom I think the issue is that the formating fn reduces the precision for higher values. Need to work on that eventually.

Are you guys getting sometimes:

Code looks great, works as expected. Only concern is their API failing some times...

[nenadV91]

Yes, it was mentioned before https://gnosisinc.slack.com/archives/C025G521XQD/p1632209701016600. Could be that our code sometimes produces more then one request to Paraswap almost instantly or in the time span of few seconds and they now limit some of those but I'm not sure about this.
