Building a Custodial crypto wallet

We are building a non custodial crypto wallet using account abstraction. Since AA allows for transaction batching we are also building a complementary marketplace for devs to deploy their strategies (1click automations) so that a user doesnt have to leave the wallet. Example Yearn Strategies and Donkey finance.

In addition to the marketplace web app, there will be a GitHub repository containing a base strategy with hooks (like the hooks _beforeTransfer, _afterTransfer), allowing developers to create their own customized flows.

1 cent base fee on all transactions + 20% murkup on gas. this fee is split 50/50 with the deployer of the automation.  

You will be building a number of base defi automations (batched transactions) + design and develop an onchain strategy factory for strategy deployment. Creation of all the necessary documentation for other developers will have to be worked on in parallel (wrappers, building blocks for strategy creation, helpers, protocol integration handlers, token handling)

Once you grasp the idea i would like to hear what would be your approach to designing and developing the onchain strategy factory.

So please write a proposal with your detailed approach. 

I will continue discussion with well written proposal candidate.

Regards.
