Refactor/refactor provable types #388

saitunc · 2026-01-12T10:44:35Z

Changes

In this PR, it is aimed to convert from provable types to non-provable types in out-of-circuit code.

Starting point changes in this refactoring was to implement or convert to JSON type of the followings:

Block
BlockWithResult

And since they are

TransactionExecutionResult
PendingTransaction
StateTransitionBatch
UntypedStateTransition
NetworkState

Especially last 3 is used all around the Sequencing and Tracing modules.

TransactionExecutionResult

Implemented Json interface, TransactionExecutionResultJson b017bb5
Implement conversion function between json type and provable type to use when needed 08f95bb

-    console.log("tx nonce", tx.transaction?.nonce.toBigInt());
+    console.log("tx nonce", (tx.transaction as PendingTransaction).nonce);


Why do you do this? tx should already be of type PendingTransaction, no?

packages/persistance/src/services/prisma/mappers/EventMapper.ts

 import { ObjectMapper } from "../../../ObjectMapper";

-type EventData = {
+type EventDataJson = {


I think we should leave this as EventData - there's not provable version of it, so that name is fine imo

packages/persistance/test-integration/PrismaBlockProduction.test.ts


+      let txHash: string;

+      if (transaction.transaction instanceof PendingTransaction) {


Whaat - why do we have this conditional in a test?

    }

-    if (lastProcessedBlockHeight === Number(block?.block.height.toBigInt())) {
+    if (lastProcessedBlockHeight === Number(block?.block.height)) {


Can't we skip this cast to number since it's already a number?

    const args = await methodEncoder.decode(fieldArgs, []);

    const { fields, auxiliary } = methodEncoder.encode(args);
+    const hash = Poseidon.hash([


Like I mentioned in PendingTransaction.ts, we shouldn't do this!

-    ).toStrictEqual(batch!.toNetworkState.hash().toString());
+      new ProvableNetworkState(
+        ProvableNetworkState.fromJSON(


We have these 5 lines at least 20 times in the codebase - should we make NetworkState a class and implement toProvable and fromProvable on it?

Not sure - even though toProvable and fromProvable will be good to remove these parts, we could need fromJson and toJson in that class too.

Maybe not though, have to check where NetworkState is used.

packages/sequencer/src/mempool/PendingTransaction.ts

+interface PendingTransactionJSONType {
+  hash: string;
+  methodId: string;
+  nonce: string;


Why is nonce a string? It should be a number

packages/sequencer/test/settlement/Settlement-only.ts

  async function createBatch(
    withTransactions: boolean,
    customNonce: number = 0,
+    // Why is it like this?


What are you referring to?

A note for myself that where i thought of using PendingTransaction as json, this line will be removed.

packages/stack/test/graphql/graphql.test.ts


-    const txHash = tx.transaction?.hash().toString()!;

Yeah no, we need to fix the PendingTransaction implementation :)
