Utils

In this library we include several utility functions used for tests and other tasks like deployments.

Hardhat-Retry

We include hardhat-retry to enhance the stability of tests in the projects using Hardhat. It automatically retries due to network issues like:

• Header not found. This occurs if the node fails to locate the requested data temporaly.
• -32000: execution aborted (timeout = 10s). This occurs when a network request timeout or node delays.
• Gas related errors. This occurs during retries so we set initialBaseFeePerGas to 0 so we mitigate it.

hardhat.config.js

To use hardhat-retry add the following to your Hardhat configuration file:

const hretry = require("@ensuro/utils/js/hardhat-retry");

hretry.installWrapper();

To enable hardhat-retry works correctly you must configure the hardhat network settings. Add this network config to hardha.config.js:

networks: {
    hardhat: {
      initialBaseFeePerGas: 0,
    },
  },

Verifiable binaries

The verifiableBinaries module enables the use of compiled contracts, fetched from NPM packages.

hardhat.config.js

const verifiableBinaries = require("@ensuro/utils/js/verifiableBinaries");

verifiableBinaries.wrapEthersFunctions();
verifiableBinaries.addTasks();
