Dear Developers!

We want to build a Python (or javascript,react) API that interacts with ETH, AVAX, and BSC blockchains in the following way:

1. Is able to read any and all readable contracts/contract properties/fields for current and historical data.
2. Is able to write to any and all writeable contracts/contract properties/fields.

Result: This is a piece of code that is effectively a unified dex read AND write/trading api supporting (currently required) three chains, with possibility to later extend support for other chains.
We want to apply our trading algorithms in defi markets, and thus require automated execution solution (through wallet like metamask or similar) to interact with dexes like sushiswap, traderjoe and many others.

If you are competent and can complete the above in quality code and quickly - please DM with a tag “DEFI API REQUEST”. Thanks
