Being able to test modifications of T-o-T rollup requires to find the best way to test the deployment and execution of smart contract on such rollups.

There seems to be two ways of doing this :

• I. originating a SR in a testnet and interacting with it through the L1
• II. using the smart-rollup to test the kernel without having to go through a L1 infra, see https://tezos.gitlab.io/active/smart_rollups.html#testing-your-kernel

Option I. is more end-to-end, allows to use t-o-t tools but involves latency Option II. requires less infra, but might be harder to observe.

Outcome of this milestone should be:

1. a motivated decision on which of this option is a better fit for testing polyrun output
2. a step-by-step reproducible walkthrough of the test
