Shipped as part of CosmJS 0.29.0

webmaster128commented, Sep 14, 2022

The point I am trying to make is that parseCoins does not do any arithmetics. It splits and checks a string and converts a string number to a string number after this has been checked to be [0-9]+. So we can get rid of the UintXYZ limitation entirely.

We use bn.js for historic reasons and I’d like to avoid creating more usages of it. I’d like to use native BigInt but the React Native folks make me wonder if we can use it in critical places.

Anyways, I’ll fix this one way or another.
