This can be especially problematic if you want advanced community features. The limitations of the free plan can be a major problem depending on how you plan to grow and use your community. One of the biggest issues is that only your most recent 10, messages are searchable. This is a major issue as the discussions that take place in a community are one of its most valuable assets. Every message that becomes unsearchable results in diminished value. Imagine you hosted an AMA with an expert in your industry: once you reach the limit, that content will no longer be searchable.
PDFs, slide decks, images, webinar recordings, and more will all quickly eat up your allowance. You may reason that when you grow out of the free plan, you can simply upgrade to the paid ones. While this is true, large communities will find themselves with a huge monthly bill. I then used this to estimate how much it would cost the people running the community to use the paid version of Slack. Even smaller communities can end up with hefty bills.
Each Slack community looks the same, lives within the Slack app, and is covered with the Slack branding. Yes, you can add integrations and automation. The image below shows how you can make a community your own with a platform like Tribe. Check out the custom domain, logo, custom colors, and unique imagery. All these features elevate your community from being just another Slack group to being a powerful platform in its own right. Members access Slack communities via the desktop, mobile, or browser app.
Each group is only available to people who know about the community and receive an invite. This is fine for closed communities, or if you have a large email list of people you want to invite. There are many reasons why you might want to do this. Some of the most successful communities are open.
Ultimately, being open increases the chance of people becoming aware of your space. This means you may grow your community far faster than you would otherwise. The problem is nowhere near as severe as it is if you decided to create a Facebook group, but it can be an issue nonetheless.
Slack is missing a host of dedicated community features. This is my biggest frustration with Slack communities. An activity feed that highlights important conversations users may be interested in is a much better solution. Slack profiles are limited compared to what we are used to on social media. They display little more than your name, job role, and some basic contact information. Slack also lacks networking features like the ability to follow other community members.
This makes it hard to keep up to date with what other people are doing on the platform. With Slack, it can be very difficult to moderate the community and keep it spam-free. There is no way to block posts based on keywords and empower the moderation team as well as community members to report content and peers. Hard to create an effective system to reward community members for their contributions.
For example, unique badges and reputation scores are some of the tried and tested ways to promote healthy competition. Understandably, a community builder will want to start a community on Slack to test the idea and see the traction. When the community picks up momentum it is best to opt for a dedicated community platform. For example, Tribe lets community managers build communities that include the features people love about Slack: things like spaces, commenting, and emoji reactions.
Hi Horace, I was getting this same error - my issue was that I had re-deployed my contracts and their addresses had changed, so I had to copy-paste the new addresses to the top of App. Nice run Nader — thanks for this. I am a newbie in Ethereum and I got this error after make some tx with the same account:. Nonce too high. Expected nonce to be 0 but got 4.
Note that transactions can't be queued when automining. If you got this, I figured that there is a limit I think it's 4 per block on the number transactions the same address can have on the transaction pool, so just by adding another account in metamask works again :. Good call out. You can also go to advanced settings and reset the account which will fix this as well. Likewise, thanks for this great post. I had the same issue and did resolve it using the methods above. Could you elaborate further on the problem here?
Is this just a quirk for the hardhat local network or is this something related to ethereum in general? I believe it has something to do with the nonce being out of sync, but I don't know a lot more than that. I usually get that when I put in a signer instead of the signer's address.
The basic idea is that you're putting in something other than a hex address, so the compiler's first thought is that it must be an ENS address ENS addresses are a way to attach a url-like identifier to an address, like vitalik. Great run though, thank you. I think the latter is probably more popular? I hadn't heard of hardhat previously, so will give it a whirl.
I too prefer ethers to web3; I liked the documentation more. Often with these choices though, you just have to choose and go. Otherwise you can spend your entire time choosing rather than actually coding I think either are good choices, but after talking with a few people in the space and hearing that some projects like Aave, Decentraland, PoolTogether, Synthetix, and others were now using it I decided to go with Hardhat.
I am a long-time truffle user but planning to switch over hardhat for a couple of reasons. In hardhat, you have support for multiple solidity compilers simultaneously, it's really helpful say if you have a 0. Truffle will refuse to compile and you have to perform some hacks to make it work. Hardhat also has this nice collection of extensions like: console.
I also found some minor problems in the truffle development chain like they set a hard block limit which is lesser than the main net limit which may result in your transaction being reverted. This is such a great run-through on such a complex topic. I was aware of a lot of these tools but never leveraged them because of how dense the docs and content usually are. I am looking forward to learning more about this space from you. Keep it up! I went to the faucet site, but it contains a certificate error.
Maybe that faucet is no longer valid? The Ropsten Ethereum Faucet said I was spamming, so I just ended up using this one instead -- faucet. Looks like the test faucet in the tutorial is working again. I guess they updated their certificate. I am doing this project in typescript, when I run "npx hardhat node" it throws an error saying. The token on that extends the ERC20 standard, and I ran into some issues here. This is the best full-stack dApp tutorial I've seen.
I wish I had this a few months ago before I already learned it. The only thing I think is really missing for a starter tutorial in a future post maybe? But really, well done. Can't wait for it. Thanks Nader. One more question tho. I'm a backend dev with Node. This is n awesome tutorial, thanks! I am stuck while trying to set the greeting, I have this error in my console:. Verify your hardhat. I had this error too, I resolved it by connecting my meta mask, you'll see the connect button on meta mask click on it.
When I run the React server to test the greeting, the "Fetch greeting" button does not prompt Metamask to sign. The "Set greeting" also does not prompt MM. I ran into the same issue - you'll just need to reconnect MetaMask: ethereum. Maybe you need to keep "npx hardhat node" running when you are using react-app.
If I don't keep it running, there will be no sign in a moment, after that, errors happen. I'm running into an issue where the deployed contract addresses have already been used previously. What's a straightforward way to force the contract to deploy to another address? I tried changing the solidity files slightly and re-compiling them, but no luck. I did the same thing and no luck as well. Tried restarting the node and the contracts were deployed to the same address. How do you feel about the hardhat-react plugin?
Is that something that could be included in this guide? It autogenerates typed React hooks integrated into the Hardhat smart contract watch pipeline and gives you hot reloading while developing contracts. So symfoni makes it easier to connect the back-end dapp code eg. So for example, wanted to make a website the will result in exchanging an NFT for ether, symfoni would make it easier? That's right. Symfoni, together with Hardhat, does all the heavy lifting and repetitive tasks for you.
I'm getting this error. Any idea how to fix this? This is the problem of my newspaper. Why is it like this? Can it solve this problem? I have followed the steps in the tutorial and refactored it several times. The errors are the same. I wrote a blog post "How to make a fullstack dapp with React, Hardhat and Ethers js" following this. Almost a year old and this is still the best tutorial out there, IMO.
I don't know what to do, I can't find an answer online. Has anyone encounter this frustrating problem. I am new to this, but have been at it for several months with different projects and i think I got the basics down. But this one is stumping me! Same here actually. JS works just fine, TS has such unexpected undebuggable issues. UPD: ok, as usual it turned out to be a simple missing await but one level higher that I've forgotten to look at :.
It also got me thinking that you could probably write codemods for Solidity files. Anyways, small brainfart lol. I am also trying to deploy such full stack react application to fleek, but the problem I have is that artifacts folder is in. Has someone tried that, maybe? Hello, I got this error when I update my app. I'm looking forward to trying out CryptoZombies to get the hang of Solidity, and going through the docs for Hardhat and ethers.
In order to fix the error, simply go to your extensions manager in VS code, click on the solidity extension should be Juan Blanco , click the down-arrow on the "uninstall" button, click "install another version", and then click 0.
After restarting your VS code application, the error should be gone. Anything Blockchain explains it in the video below. Hi, I ran through the first half of the tutorial the localhost example greeter yesterday and stopped. This might be a very silly question since the localhost server that it was connected to is not even running anymore, so now metamask has the network set to ethereum mainnet. So apologies if my question makes no sense. But I clicked on the coins, and then read after some googling that this is commonly how metamask scams work!!!
Can anyone explain why this happens with the test wallet? And we don't see that, or I don't. With truffle the contract address was inside the artifact file on networks. Are there something like that on hardhat? Are you sure you want to hide this comment? It will become hidden in your post, but will still be visible via the comment's permalink.

Ethereum development environment When building smart contracts, you will need a way to deploy your contracts, run tests, and debug Solidity code without dealing with live environments. Ethereum Web Client Library In our React app, we will need a way to interact with the smart contracts that have been deployed.
What we will be building In this tutorial, we'll be building, deploying, and connecting to a couple of basic smart contracts: A contract for creating and updating a message on the Ethereum blockchain A contract for minting tokens, then allowing the owner of the contract to send tokens to others and to read the token balances, and for owners of the new tokens to also send them to others.
We will also build out a React front end that will allow a user to: Read the greeting from the contract deployed to the blockchain Update the greeting Send the newly minted tokens from their address to another address Once someone has received tokens, allow them to also send their tokens to someone else Read the token balance from the contract deployed to the blockchain Prerequisites Node. Getting started To get started, we'll create a new React application: npx create-react-app react-dapp Enter fullscreen mode Exit fullscreen mode.
