What's the correct way to replay the events on v4 chain?

[miran248]

Hey,

I'm currently exploring what's stored on the chain with a goal to do some analysis (and maybe make my own indexer later).

I've successfully established the connection with some mainnet validators and checked a few blocks so far.
It looks like all blocks contain these four messages

"/dydxprotocol.clob.MsgProposedOperations"
"/dydxprotocol.bridge.MsgAcknowledgeBridges"
"/dydxprotocol.perpetuals.MsgAddPremiumVotes"
"/dydxprotocol.prices.MsgUpdateMarketPrices"

I'm wondering, what's the correct way to decode them?
This is what i came up with so far https://github.com/miran248/dydx-v4-test/blob/a6581251eacfa488c85f564287fb1955097a0555/validator-client.ts#L6
Feels wrong, and MsgProposedOperations was not fully decoded

Are there any other ways to replay the events?
Indexer has some functions but there i can't target a specific block height.

(didn't know where to ask this question, hence the issue)

Thanks,
Miran

EDIT: It looks like i'll have to do the mapping myself, like here https://github.com/dydxprotocol/v4-clients/blob/c94bcbf4fc91bb896ea716ccd02ace32b0cb50d0/v4-client-js/src/clients/lib/registry.ts

Have you found a method to decode shortTermOrderPlacement?

@yllhwa Hey, unfortunately no. I gave up shortly after.
Might revisit it at some point, once I get more familiar with cosmos-sdk in general.

All right, I figure it out.

import { decodeTxRaw } from "@cosmjs/proto-signing";
var data = decodeTxRaw(operation.shortTermOrderPlacement);
console.log(data.body.messages);
// decode message then

what brilliant developers and detailed documentation we have.

Tried that too but not sure if it's correct.

Have you seen this? https://github.com/dydxprotocol/v4-chain/blob/e6b269186c9800a3af973171f2290e6fa94765db/protocol/x/clob/types/operation.go

Msg here is of type MsgPlaceOrder, at a quick glance it appears to be a request type though..
