Moonriver is a companion network to Moonbeam and provides a permanently incentivized canary network. New code ships to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code ships to Moonbeam on Polkadot. Community members will own a majority of the MOVR tokens on the network, giving them considerable control over the direction of the network. While Moonbeam code launches to Moonriver first, the network will continue to live on as a parachain on Kusama, with its own projects and specialized use cases. The Moonriver network deployed as a parachain to Kusama in June , and Moonbeam will deploy to Polkadot later this year.

Uniswap v2 (as a Developer)


Hi there! Today I want to share with you what was my first project, the creation, and deployment of an ERC20 token. In this article, we will provide the code for a simple cryptocurrency as well as all the steps that are necessary to get your token up and running on the Ethereum network. For those interested in a more visual experience, I recorded a full session explaining all the contents of this article and doing the programming and deployment live.

You can watch the view here:. There are a few things that we need to prepare in advance before creating our token, and those are described below. You probably know Ethereum and its network, however, did you know that there are multiple instances of Ethereum running?

Most people are familiar with the main Ethereum network, where all the transactions are running, and where all exchanges operate or at least should. One of the benefits of using a test network is that, not only we can submit any code we want and test it out, but also we can do it free of charge. Every time a new token is created, it is necessary to register a transaction on the Ethereum network it is running. And this transaction will come with a GAS fee which we will need to pay with Ethereum from the network.

Not very convenient to just try it out. However, the beauty of the test network is that we can get free Ethereum using applications called faucets. Now that we know which network we want to use to build and deploy our token, we need to create a wallet and an account into that network.

I strongly recommend that you use MetaMask for this task. MetaMask is an extension that runs as an extension on your browser and allows you to create accounts in multiple networks and it has integrations with the deployment interfaces we are going to be using today, making the job much easier than with any other method.

Next, you will need some fake ETH in your account. Normally they will ask you for your account number public and with only that information they will transfer you X amount of ETH, normally 1, which is more than enough for our purposes. Next, we need to think about the cryptocurrency we want to create and what properties are those going to be. You will need the following information before we actually get started:. Last but not least, you will need to code which will run our own cryptocurrency.

Once there you will notice at the beginning of the file something like:. The first line of code is simply required to run any solidity program, but the rest is where it gets interesting. What I did to facilitate how to work with the code, is that each of these variables needs to be assigned a value, and once they are all completed, you will have the code ready and this comment section will be a nice description of our token. So, how we go about updating it? You need to find and replace all occurrences with each one of them.

This is very easy to do in any code editor. Next, we need to specify the total supply and the decimals, which go hand by hand. You may be wondering why. Then our variables would be replaced as follows:. However if we want to have some decimals, say, 2 decimals, then we would need to modify the total supply, by adding a zero for each decimal at the end of the desired number.

Awesome, we are almost there. We now only need to specify the account which will receive all the tokens that get created. Head to MetaMask and copy your account number, and once more, find and replace the variable in all occurrences. At the end your code should look like this:. Our file is now ready for deployment, that easy! The good people from Ethereum provide us with an IDE integrated development environment that is fully capable of handling the full process, from editing the files, building, and deploying, among many other things.

The first section we see on the left is our contextual menu, and in the right section we see the welcome screen. As we are by default on the file explorer the contextual menu shows all the files and folders that are available. There are already a few files in there now, but you can ignore them. Once the file is created simply past the code that we worked on your text editor. It should more or less look like this:.

Our code is now ready to be compiled. For that, look at the icon bar on the left of the corner. The moment you do that, MetaMask will prompt you to confirm that you want to connect your MetaMask wallet to Remix, hit confirm. The deployment process may take anywhere from a few minutes to up to who knows how many minutes depending on the status of the network at that time. Usually, I found that Ropsten will take 2 to 3 minutes, and the maximum wait time I had was 10 minutes. After the process is complete you will receive a confirmation on the screen with the information of your deployed contract, including the address where the code got saved.

Up to this point, our token already exists in the Ethereum network and can be used to transact, however, how do you access your tokens? Turns out that MetaMask as well as other walltes can already operate with your token as it follows a specification called ERC However wallets are not yet aware of the existence of your token, so you will have to manually add them.

One important data on that screen is the address where the code got deploy, please copy that using the copy icon on the right, highlighted in the picture above. This will automatically populate the token symbol and decimals fields. You can now see your tokens on your MetaMask wallet.

Today we learned how to build and deploy your own cryptocurrency by following the ERC20 interface and utilizing Remix and MetaMask. The process is super easy, and the code we provided though working is just a minimal example.

You can build many great things on top of what we did today, and I hope I can hear from you all the great projects that you build using the power of blockchain. I really hope that you enjoyed this tutorial. MIT Licence. Total Supply: Decimals: 0.



How To Use Remix and Metamask To Deploy Smart Contracts On The RSK Testnet

In Ethereum blockchain, smart contracts are immutable, public, and distributed. However, they are subject to many vulnerabilities stemming from coding errors made by developers. Reentrancy vulnerability was the cause of two of these incidents, and the impacts went far beyond financial loss. Several reentrancy countermeasures are available, which are based on predefined patterns that are used to prevent vulnerability exploitation before the deployment of a smart contract; however, several limitations have been identified in these countermeasures. Motivated by all these issues, the objective of this article is to help developers improve the cybersecurity of smart contracts by proposing a solution that calculates the difference between the contract balance and the total balance of all participants in a smart contract before and after any operation in a transaction that changes its state.

Tokens created with the Ethereum platform use a standard coin API to be of the compiler from Remix to compile the solidity Ethereum smart contract code.

But how does Uniswap work as an integration to your website? Here is my step by step walk-through, from a developers perspective. A walk-through I wish I had three weeks ago. When you look at the uniswap documentation then you see an SDK in Javascript , you see Smart Contracts documentation which use contracts in two different repositories and you also find Custom Linking and Iframe Integration. All of them cover a specific angle of requirements.

Whirlpool is a zerolink coinjoin implementation created by the Samourai Wallet developer team. It is the most structurally sound and easy to use implementation on the market today. Whirlpool breaks all deterministic links between inputs and outputs and provides the user with market leading postmix spending tools to allow for proper spend hygiene after mixing. At a very high level, a Whirlpool mix is a collaborative transaction between 5 participants. The outputs of each Whirlpool mix are always identical resulting in every mix having possible interpretations. Anyone surveilling the blockchain and looking at a Whirlpool transaction cannot say for sure which output corresponds to which input.

Select the Solidity button under the Environments heading and this will add the required plugins. The plugins are shown on the left hand column. Note: When importing via GitHub, you should specify the release tag, otherwise you will get the latest code in the master branch. For OpenZeppelin Contracts you should only use code published in an official release.

This means you can deploy an Ethereum smart contract to the Polygon Network. Polygon supports Ethereum consensus, smart contracts and staking instead of POW for the native Matic token.
