@0x/subproviders

A few useful web3 subproviders including a LedgerSubprovider useful for adding Ledger Nano S support.

We have written up a guide article detailing some use cases of this subprovider package.

Read the Documentation.

Installation

yarn add @0x/subproviders

If your project is in TypeScript, add the following to your tsconfig.json:

"compilerOptions": {
    "typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
}

Contributing

We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.

Please read our contribution guidelines before getting started.

Install dependencies

If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:

yarn config set workspaces-experimental true

Then install dependencies

yarn install

Build

To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:

PKG=@0x/subproviders yarn build

Or continuously rebuild on change:

PKG=@0x/subproviders yarn watch

Clean

yarn clean

Lint

yarn lint

Run tests

Unit tests

yarn run test:unit

Integration tests

In order to run the integration tests, make sure you have a Ledger Nano S available.

  • Setup your Ledger with the development mnemonic seed: concert load couple harbor equip island argue ramp clarify fence smart topic
  • Plug it into your computer
  • Unlock the device
  • Open the on-device Ethereum app
  • Make sure "browser support" and "contract data" are disabled
  • Start TestRPC locally at port 8545

Then run:

yarn test:integration

Note: We assume a derivation path of m/44'/60'/0'/0 which is already configured in the tests. With this setup and derivation path, your first account should be 0x5409ed021d9299bf6814279a6a1411a7e866a631, exactly like TestRPC.

All tests

yarn run test:all
