Summary

We need to investigate how easy / difficult it would be to add CosmWasm to our chain, and experiment with how we would use it.

@RafilxTenfen will be doing the initial investigation.

What we need to add cosmwasm

• Cosmwasm: (HAL-01) VULNERABLE WASM SMART CONTRACT LEADS TO CHAIN HALT #1189
• Cosmwasm: (HAL-02) - WASM CONFIG PARAMETERS ARE NOT COMPATIBLE WITH RECENT COSMWASM SDK #1190
• Cosmwasm: (HAL-03) NEW QUERIES ARE NOT ADDED INTO THE HANDLER #1191

"The provided cosmwasm module is a minimal, unopinionated implementation of bindings between the SDK and the smart contract VM. It is embedded in wasmd, which is a fork of gaiad with x/wasmd added. It takes care of all the implementation details, but leaves the field open for you to fork this repo and add custom business logic around it."

I will try to do something like Juno
