This repo showcases a problem when deploying contracts with the oz CLI
tool while using Ledger Nano to sign the transactions. The problem comes from the
ledger web3 provider.
Steps to reproduce:
# Clone the git repository:
git clone https://github.com/PetarKirov/oz-ledger-problem-repro.git
# Enter the repo dir:
cd oz-ledger-problem-repro
# Copy the sample `.env.example` file to `.env`
cp .env.example .env
# Open the `.env` file and fill the INFURA_KEY env variable
# Install npm dependencies
npm i
# Intialize openzeppelin project (confirm all prompts):
npx oz init
# Test contract deployment on `kovan` network using HDWalletProvider:
npx oz create JarvisRewardToken --network kovan --init 'initialize()'
# (Observe that the deployment succeeds.)
# Test contract deployment on `kovan_ledger` network using LedgerProvider:
npx oz create JarvisRewardToken --network kovan_ledger --init 'initialize()'
# (Approve all transaction signing requests on the Ledger)
# ...Observe that the deployment fails with following error:
✖ Creating instance for contract at 0xD39cB619356332591Ea141eb73c788124B0b9E91 and calling 'initialize' with no arguments
Failed to subscribe to new newBlockHeaders to confirm the transaction receipts.
