Testnets provide free cryptocurrency you can use to pay for gas fees. To put it simply, you should test your smart contracts on a testnet before deploying them on the mainnet. Rinkeby is an Ethereum testnet that is used to test the Ethereum protocol. It is a fork of the Ethereum mainnet. Rinkeby enables you to develop your DApps in a test environment before deploying to the real Ethereum mainnet.
Rinkeby was built in April by the Ethereum Foundation and is maintained by the Geth developer team. It uses the proof-of-authority consensus mechanism. Loading the Rinkeby site at rinkeby. Rinkeby displays the network stats, including the number of nodes, transactions, and blocks. In addition, it shows the number of transactions per second, the number of blocks per second, and the number of peers, which is the number of nodes that are connected to Rinkeby.
To write a smart contract and deploy it on the Rinkeby testnet, the first step is to install the MetaMask extension on your desktop browser. First, go to the Chrome store and search for MetaMask. Click on the MetaMask extension and install it. After the installation, go to the Chrome menu and click the Add-ons button.
Then, click Extensions and then MetaMask. MetaMask will pop up and prompt you to sign in. After that, you can sign in to MetaMask. Localhost is an Ethereum node running locally on your machine.
First, we have to copy our Ethereum address. To do that, click the Copy icon to copy your Ethereum address. The official faucet is located here.
Paste your Rinkeby testnet address and get free Eth. There are also third-party sites that provide free Eth on the Rinkeby network, such as the Rinkeby Ether Faucet. It is quite difficult to get free Eths on the Rinkeby faucet. It involves publishing a social media post for Rinkeby and waiting eight hours to earn 3Eth, one day to get 7.
Thats a long time to to wait. Rinkeby uses only the Geth client to make transactions on the network. This forces you to switch to the Geth client when making transactions on the Rinkeby network. This is another huge setback.
One key advantage is that Rinkeby uses proof of authority, which is quickly gaining adoption in the blockchain world. Kovan is another testnet that is used to test the Ethereum protocol.
Like Rinkeby, Kovan is a fork of the mainnet. Kovan was built in June by the Ethereum Foundation and, also like Rinkeby, is maintained by the Geth developer team. It uses the proof of authority consensus mechanism as well. In general, Kovan supports the same features as Rinkeby. You can also use the official faucet to get free Eth on this Kovan testnet.
It shows the latest blocks, the latest transactions, and ERC, ,- and tokens. You can also search addresses, transactions, blocks, etc. To get a free kEth in Kovan, you can use the official faucet. You can instantly get one KEth per 24 hours per GitHub account. You can also get free kEth in the Kovan Gitter chat room. Kovan uses the proof of authority consensus mechanism, unlike Ethereum, which uses the proof of stake consensus. This makes the Kovan testnet a bit different from the Ethereum mainnet it represents.
Getting free Eths on Kovan is relatively easy compared to other testnets. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search.

All you have to do is send your Eth address to the Kovan Gitter channel. Ropsten was created in August by the Ethereum Foundation and, like many popular Ethereum testnets, is maintained by the Geth developer team. The Ropsten site , just like the Kovan test network site, shows the latest blocks and latest transactions.
You can also view ERC, , and tokens as well as search addresses, transactions, blocks, etc. To get free Eth on the Ropsten testnet, we can use the official faucet. The Ropsten test network is considered to be the test network that is most closely related to the Ethereum Mainnet.
The consensus mechanism is proof of work. In February , Ropsten was attacked and brought to a halt. Developers can use a Rinkeby Faucet to get free testnet ETH and test their smart contracts without the risk of losing real financial assets. Authorized nodes can only create new blocks, meaning no other nodes can be awarded mining rewards. This article will explain the Rinkeby testnet, its main uses, the Proof-of-Authority PoA consensus mechanism, how to get Rinkeby testnet ETH from a Rinkeby faucet, how to send testnet ETH to other wallets, and the best Rinkeby testnet tools to help accelerate your journey developing dApps.
The Ethereum team launched the Rinkeby testnet in using a modified proof of authority consensus model, and will be deprecated in favor of using the Goerli testnet, another popular testnet that uses the proof of authority consensus mechanism. The PoA consensus protocol is now maintained by the Geth team. There are currently about 11,, blocks on the network and as of , Rinkeby had about 50 million transactions. There are 46 active nodes in the Rinkeby testnet, and the block time for the Rinkeby testnet is about 15 seconds.
The max limit a block can be filled up with transactions is about 41, The Block gas limit for the Rinkeby testnet is about 30 million gas. The gas limit refers to the max price a cryptocurrency pays when sending a transaction, or performing a smart contract function in the Ethereum blockchain. Fees are calculated in gas units, and the gas limit defines the maximum value that the transaction or function can "charge" or take from the user.
With the gas price at about 1, gwei and 0. For the most up-to-date stats, check out the Rinkeby statistics page. Using PoA enhances security overall in comparison to PoW. Developers also choose Rinkeby over other testnets due to its faster block time. Ropsten has a block time of about 30 seconds, but Rinkeby cuts that time in half. The chain data size for Rinkeby is only about 6GB. This is different from the Ropsten testnet where miners on the network have a financial incentive to maintain the testnet itself.
The Ropsten testnet also uses a PoW consensus mechanism, which makes it identical to the current Ethereum consensus mechanism which also uses Proof of Work. The main use case for using the Rinkeby testnet is for developers to test their applications in a controlled testing environment that functions like Mainnet Ethereum without taking the financial risk to execute smart contracts, iterate application features, and perform functionality.
They deploy their marketplaces on Rinkeby and Rarible to deploy their NFT marketplaces on Rinkeby before deploying on mainnet. Developers also use the testnet as an educational tool. Often, developers make several mistakes along their journey. Using a testnet enables them to enhance their understanding of how to use the main network better in the future.
Finally, developers use Rinkeby to test upgrades to the underlying platforms. This is essential to create better developer tools for the Web3 ecosystem and to create more libraries, better documentation, and essential feedback overall. All these use cases relate to creating a safe space for developers to thrive. Without testnets like Rinkeby, developers would bear the consequences of potentially losing real-world assets, and they would have to be more careful interacting with their smart contracts.
You can easily receive testnet ETH through a testnet faucet. Testnet faucets exist so developers can request funds and continue testing applications without real financial risk. Here is how to make a test account for a Rinkeby faucet:. This is very important. Sign up for a free Alchemy account to get five times as many testnet Ether tokens as you would without an Alchemy account.
As always, please try it out and share this with developers building on the Rinkeby testnet that need fake ETH tokens. If you have any feedback, feel free to let us know in Discord! Select the send button within your Metamask wallet. From here, paste in the address of the wallet that will receive your testnet ETH. Click confirm to send your transaction. Be aware that there are still gas fees within testnets which have no real value. Rinkeby works best with other blockchain developer tools to ensure you have a great experience creating decentralized apps using a modern web3 tech stack.
Web3 developers should consider the depth and breadth of developer tooling that is available. Two of the most used Web3 native libraries include ethers. These libraries natively support remote procedure calls RPC to blockchain nodes hosted on the blockchain interaction layer. Alchemy has another Web3 library. The alchemy-web3. Fortunately, EVM-compatible chains benefit from years of Ethereum development and have a host of battle-hardened options when it comes to development environments.
Hardhat, Truffle, and Brownie are all great options when it comes to development environments in Web3. These developer environments allow developers to compile, test, deploy, and debug Ethereum software and testnets like Rinkeby. In addition, they come with more tooling and easily customizable local blockchain development environments.
Decentralized storage fills in the gap for expensive and inefficient frontend content like images, videos, and GIFs. Development platforms like Alchemy provide a large suite of tools for testing and finding bugs: Supernode , Build , Monitor , and Notify makes this whole process much more convenient.
As web3 grows from its current state to maturity, there will surely be paradigm shifts, new web3 infrastructure tools, and plenty to learn. Using testnets is an essential step to developing in web3 before deploying to Ethereum mainnet. With the Rinkeby testnet deprecated, developers can build while having the security, speed, and scalability alongside additional tools on the Goerli test network. Join a growing movement of developers�both Web3 natives and fellow travelers from Web2� and together we can build the future!
