Proposal: Transaction Profiler DPM Component

[shanu12joshi]

Development Fund Proposal Submission

Proposal file:
/proposals/transaction-profiler-dpm.md

---

Summary

We are building a DPM Component, Canton Pre-Flight Transaction Profiler that estimates sequencer traffic cost and checks validator readiness before a transaction is submitted to the Canton network, built for validator, operators and multi-party workflow developers. Similar to how Tenderly works on EVM. The component estimates what a transaction will cost and whether it will succeed before it is submitted.

Total request: 130,000 CC across four milestones over one months.

@shanu12joshi, thank you for your interest in the Canton Development Fund!

Your proposal needs a valid Tech & Ops Committee champion organization. The champion field is either empty, contains placeholder text, or names an organization that is not a current Tech & Ops Committee member.

Per CIP-0100, all external proposals require a Tech & Ops Committee champion.

Next steps:

1. Identify a Tech & Ops Committee member organization willing to champion your proposal
2. Update the Champion field with their name
3. Reopen this PR

If you need help finding a champion, reach out to SIGs or any Tech & Ops Committee member.

Hey @hrischuk-da , I have found a champion for this PR, Would it be possible to get this marked as ready to champion?

I understand the problem this is trying to solve. However, I think this proposal is too narrow to be really helpful since it is using the tx prepare statement and doing a CC conversion. I expect most validators will have an auto-top up enabled so they won't run out of traffic. The validator will be moving to party based traffic costs so this approach will become obsolete shortly.

I do think a tool around traffic has merit but it would need to be much more functional in that it is tailored to help the developer design for minimizing traffic cost.
