    balancer-sor

    Smart order router: off-chain linear optimization of routing orders across pools for best price execution

    There are two types of swap available:

    swapExactIn - i.e. You want to swap exactly 1 ETH as input and SOR will calculate X amount of BAL you receive in return.
    or
    swapExactOut - i.e. You want to receive exactly 1 BAL and SOR will calculate X amount of ETH you must input.

    The SOR will return totalReturn/totalInput as well as a list swaps to achieve the total. Swaps can be through direct pools, i.e. A > POOL1 > B, or via a multihop pool, i.e. A > POOL1 > C > POOL2 > B. The swaps are returned in a format that can be directly to the Vault to execute the trade.

    The example file swapExample.ts in: ./testScripts, demonstrates full examples with comments.

    To Run:

    Create a .env file in root dir with your infura provider key: INFURA=your_key

    Install dependencies: $ yarn install

    Run example: $ ts-node ./test/testScripts/swapExample.ts

    sail

    Sail is a lightweight Rails engine that brings an admin panel for managing configuration settings on a live Rails app

    This Rails engine brings a setting model into your app to be used as feature flags, gauges, knobs and other live controls you may need.

    It saves configurations to the database so that they can be changed while the application is running, without requiring a deploy.

    Having this ability enables live experiments and tuning to find an application’s best setup.

    Enable/Disable a new feature, turn ON/OFF ab testing for new functionality, change jobs’ parameters to tune performance, you name it.

    It comes with a lightweight responsive admin dashboard for searching and changing configurations on the fly.

    Sail assigns to each setting a relevancy score. This metric is calculated while the application is running and is based on the relative number of times a setting is invoked and on the total number of settings. The goal is to have an indicator of how critical changing a setting’s value can be based on its frequency of usage.
