New Chain template as a solidity contract

[Tritium-VLK]

Ernesto (DAO msig signer) pointed out that the json payloads for a new chain are very hard to verify. He suggested that we consider using solidity contracts with delegated calls.

Here is Aaves multisig repo with these contracts.

Here is an example on configuring a new market.

It seems like we could actually take any tx builder jsoin that had abi data (contractInputsValues,etc), and generate a solidity script with minimal interaces from it.

Maybe the answer is to write tooling to build solidity contracts from json data?
