Stackr allows applications to perform their own ordering of the actions inside the block It comes with a basic sequencer which can be extended to perform more complex ordering.

​
Strategies

The basic sequencing strategy bundled with the SDK is the FIFO strategy. It does nothing tbh.

import { FIFOStrategy } from "@stackr/stackr-js";

const buildStrategy = new FIFOStrategy();

​
Custom strategies

You can create your own strategy by extending the BaseStrategy and overriding the orderTxLogic class and pass it on to the rollup.

Example:

import { BaseStrategy } from "@stackr/stackr-js";

export class Randomize extends BaseStrategy {
  constructor() {
    super("RandomOrder");
  }

  async orderTxLogic(
    actions: Action<AllowedInputTypes>[]
  ): Promise<Action<AllowedInputTypes>[]> {
    console.log("Random");

    return Promise.resolve(
      actions.sort(() => {
        return 0.5 - Math.random();
      })
    );
  }
}

Not sure why but you can randomize the order of the actions inside the block like this 🤷🏻‍♂️
