This PR aims to reduce the RPC calls made by scaffold-eth on a clean install (around 60/80 per minute) by providing some sensible defaults on polling times (vs onBlock) and reusing providers (if localProvider is mainnet).

There are two new constants (with sensible defaults) that config this behavior: LOCAL_RPC_POLL_TIME and MAINNET_RPC_POLL_TIME.

On the localhost (hardhat chain) the polling is disabled (uses onBlock) to keep allowing a fast feedback loop. (We don't care about RPC requests to the localnode)

Great work @Naim-Bijapure & @technophile-04

Describe the bug the last command as mentioned on github page, "Yarn mint" fails.

To Reproduce Steps to reproduce the behavior:

1. yarn mint

Expected behavior should do usual mint code path

Screenshots

Desktop (please complete the following information):

• OS: windows 10
• Browser [chrome]
• Version [22]

I've created a branch of scaffold eth based on master that runs on Typescript and vite and react.

• The hardhat deployment/publish/ etc files are also in TS

Notes:

• i refactored most of the components to typescript
• the views are also in typescript
• it has the components from buidlGuidlv2 feature branch
• currently, all the views open
• since its based of vite instead of webpack, its much faster to load (vite runs on esbuild), it takes about 5 seconds from a cold start in my laptop

Format:

• There's 2 new package folders called hartdhat-ts and vite-app-ts that have the ts version
• I didn't modify the react-app and hardhat folders

Has the latest changes from the hardhat-deploy additionally.

Would be great to have both the scaffold-eth and chainlink-starter-kit productivity boost in one and the same project.

The Chainlink Starter Kit gets you going fast with VRF, API requests, PriceFeeds and Keeper Contracts. Mocks for unit tests are included

Describe the solution you'd like Change the hardhat project in scaffold-eth in order to be used just like https://github.com/smartcontractkit/hardhat-starter-kit.

Some work is needed with

• dependencies (check for compatibility issues - chainlink uses some older beta-release packages but not documented why)
• yarn scripts
• possibly es-lint exceptions (chainlink code contains expressions like a == b in order to have "31337" == 31337 pass as true)
• readme updates

Hi there,

Thanks for creating such a great tool for Ethereum solidity/dapps learner.

I think it is quite demotivating for any new user of the tool to hit few speed bumps just to "Quick Start".

My environment: Ubuntu 20.04.4 LTS Node v16.14.0 Npm 8.3.1

I run yarn deploy after yarn chain, the deploying "YourContract"... seems take forever.

Then I went ahead to make a small amendment to YourContract.sol, then run yarn deploy again, it prompt me the following message:

It used a gas pricing config of (gasPrice: 875000000 wei) ,
              current gas price is 1768762328 wei
              
              
? Choose what to do with the pending transaction: … 
▸ increase gas
  continue waiting
  skip (forget tx)

I choose the iincrease gas option, the command is exit with the following error:

nonce has already been used

Please advice. Thank you.

~~We have a workspace named "hardhat", but this is also the name a third-part library hardhat we are depending on. That makes IDE confused when it comes to code references..~~

~~For example~~ in VSCode:

Right now Infura is hardcoded in some places where you can only change the API key. Ideally, we should do a bit of refactoring so the developer can easily change the node provider in constants.js.

There is not good documentation or a good tutorial/branch around testing. It would be very valuable to have a good challenge around testing in order to tech the common experienced with smart contracts.

Following Austin's tutorial at https://www.youtube.com/watch?v=T5ylzOTkn-Q&t=77s.

At minute 7:06 (running yarn graph-run-node) I'm running into a problem where the graph-node_1 container isn't starting up successfully.

I'm running the Apple M1 Tech Preview of Docker, maybe that has something to do with it. Check the "Known issues" of here: https://docs.docker.com/docker-for-mac/apple-m1/

This PR adds a Docker alternative setup to spin up the stack inside a container.

If it makes sense to have, I'll need guidance about where to add current docker/README.md content.

Describe the bug Nonce state on-chain is different from nonce kept in storage in react state

Transaction Error Error: [ethjs-query] while formatting outputs from RPC '{"value":{"code":-32603,"data":{"code":-32000,"message":"Nonce too high. Expected nonce to be 0 but got 1. Note that transactions can't be queued when automining."}}}'

To Reproduce Steps to reproduce the behavior: Try any contract interaction after redeploying

Expected behavior The contract should change as expected

Purpose:

This PR introduces a new starter kit for upgradeable contracts using the OpenZeppelin Upgrades API (since there is no starter kits right now for this yet, it seems).

Includes:

• Upgrade-safe contract (UUPS)
• Upgradeable contract deploy script
• Updated readme instructions to get contracts deployed, ready for frontend
• Script for upgrading function implementation

Testing:

• Contracts wise, trivial modifications were made to the original scaffold-eth contract
• Otherwise, all upgrade-related items (deployment, upgrade script) was tested by following the readme instructions from start to finish on localhost

Suggestion:

• To include this inside a new branch of this repo, or the scaffold eth examples repo.
• Feedback welcome, wondering if we should also do a Typescript version of this (wouldn't be too difficult)
