To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
PKG=@dexon-foundation/subproviders yarn build
Or continuously rebuild on change:
PKG=@dexon-foundation/subproviders yarn watch
yarn run test:unit
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
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.
yarn run test:all
