Stackr Config

Telling the Stackr SDK how to run your app

This is how the stackr.config.ts file looks like

Everything is explained in the comments, please read through

import { KeyPurpose, SignatureScheme, StackrConfig } from "@stackr/stackr-js";

import * as deployment from "./deployment.json";

const stackrConfig: StackrConfig = {

    // the deployment script also deploys an app inbox for you where the rollup data is stored
    appInbox: deployment.app_inbox,
  },
  // the builder is responsible for building the rollup blocks
  builder: {

    // in case some transactions are invalid

    // the batchTime is the time in milliseconds after which a rollup block will be built
    batchTime: 1000,
  },
  // the syncer is responsible for syncing the rollup blocks to the L1 and Vulcan layer
  syncer: {
