VMs Support

[julienrbrt]

Ignite Apps should aim to provide scaffolding commands and helpers for integrating VMs in an Ignite chain (Cosmos SDK chains).

To keep the ignite vm experience consistent, each vm app should strive to have the same features:

Scaffolding:

• Scaffold boilerplate for Cosmos SDK chain
• Scaffold default configuration for the VM (whether it is in app.toml, app_config.go, or somewhere else)

Helpers:

• Helper for compiling contract
• Helper for deploying contract
• ...

Testing:

• Integrations tests
• Liveness tests

Currently, 3 VMs integrations are in progress:

CosmWasm

Integrate the CosmWasm VM via the Wasmd Cosmos SDK module: https://github.com/CosmWasm/wasmd.

The scaffolding part of the app is completed: https://github.com/ignite/apps/tree/main/wasm.
The helpers remains to be developped.

EVM

Integrate the EVM via the newly open sourced Cosmos EVM module: https://github.com/cosmos/evm

The scaffolding part of the app is completed: https://github.com/ignite/apps/tree/main/evm.
The helpers remains to be developped.

GnoVM

Integrate the GnoVM with the Ignite GnoVM Cosmos SDK module

The scaffolding part of the app is completed: #238
The helpers remains to be developped.

---

By having all VMs have the same features, we'll be able to provide a streamlined experience across the Ignite VMs apps.

End goal is to create a page on Ignite Tutorials comparing each VMs advantages (+ native) and tradeoffs for helping users decide which one for their use case.

Following up #197, we should extend the workflow to add liveness tests for all vms.
I'll extend for EVM in my evm PR.

GnoVM app available: #238

I also think, instead of ignite add VM's should be given in standard, like EVM needs 18 Decimals but ignite does not does this automatically, its useless if we have to go ahead and edit some Files ourselves, something like ignite scaffold chain MARS --type EVM should be provided. Just my 2 cents

like EVM needs 18 Decimals but ignite does not does this automatically

This can be a flag, but ignite apps should work for existing live chains too. You cannot just change de decimal coin so easily. This is a one line change for those wanted to use 18 decimal. I fail to see the issue.

The cli itself won't contain anything else than the sdk and IBC. The rest of the module bring extra maintenance on the main cli and slows down the releases. We could add those are default apps, but we would need to remove them at each new major release and wait until the vms module supports the new sdk version. UX wise it is confusing.

Yes A flag i mean --Type=EVM

We've listened, and 18 decimal is integrated by default in https://github.com/ignite/apps/releases/tag/evm%2Fv0.1.2.

VM's For example if i have WASM and EVM, they do not share state by Default, right? or do they
