Hardhat Ignition: A game-changer for smart contract deployment.What is it? It’s a declarative system that simplifies the deployment process, offering an end-to-end deployment experience, and lets developers focus on their projects, not deployment nuances.&nbsp;Why it’s a Big Deal? It addresses challenges like:Execution Unreliability: Gas spikes, dropped transactions, and nonce reuse complicates deployment reliability.Partial Deployment Recovery: Resuming from halted deployments requires on-the-fly code modifications.Deployment Modifications: Upgrades or additions need new ad-hoc deployment code.&nbsp;<h4>Features of Hardhat-Ignition:</h4><ul><li>Declarative Deployments 📋: Describe what to deploy; Hardhat Ignition does the rest.</li><li>Recovery Capabilities 🔄: Adjust and continue if deployment halts.</li><li>Gas Fee Management ⛽: Auto-adjusts gas fees, ensuring transactions are confirmed.</li><li>Flexible Execution Strategies 🎛️: Describe your contract action (call, deploy, etc), then separately choose the execution strategy. Whether it’s an EOA, CREATE2, a multisig, or a different contract, you can change execution characteristics without modifying your action definition.</li><li>Deployment Visualization 📊: Gain a clear understanding of the deployment process with the visualization report.</li></ul>&nbsp;Let’s automate a deployment using Hardhat Ignition:To get you started quickly we have set everything at Hardhat Ignition• Clone/fork <a href="https://github.com/BuildBearLabs/hardhat-ignition">Hardhat Ignition</a>:<pre><code class="language-plaintext">git clone https://github.com/BuildBearLabs/hardhat-ignition.git</code></pre>• Install dependencies<pre><code class="language-plaintext">cd hardhat-ignition

Hardhat Ignition verifies block confirmation upon contract deployment, and this specific mining window ensures blocks are mined even if there are no transactions on your Testnet.Once your Testnet is live, copy the RPC from the Dashboard and paste it into your Hardhat config under Networks.<figure class="image"><img src="https://cdn-images-1.medium.com/max/896/1*OXTVSS3fOBdrgg1lH7PJrQ.png"></figure>Now, let’s deploy a contract:Execute the following command:<pre><code class="language-plaintext">npx hardhat deploy ./ignition/BasicDeploymentsModule.js --network buildbear</code></pre><figure class="image"><img src="https://cdn-images-1.medium.com/max/896/1*2jPPe8d4ayJBgkmO-5mtZg.gif"></figure>Recovering from InterruptionsTeams experienced in managing smart contract systems in production are well-acquainted with real-world scenarios, such as nodes going offline, infrastructure providers encountering outages, and inconsistent connectivity, among other challenges.<figure class="image"><img src="https://cdn-images-1.medium.com/max/896/1*qEMKiQjk_FNGWQy4Hq2GIg.gif"></figure>Factory-Deployed Contract<figure class="image"><img src="https://cdn-images-1.medium.com/max/896/1*LwtzhfuJ2Ha6k6CVBp_lFg.png"></figure>This code exports a Hardhat Ignition module named “ContractFactory,” which deploys a contract factory, calls the “deploy” function, reads the deployed contract’s address from an event, and provides access to the factory and the deployed contract. It simplifies the process of deploying and interacting with smart contracts in Ethereum development.<pre><code class="language-plaintext">npx hardhat deploy ./ignition/ContractFactoryModule.js --network buildbear</code></pre><figure class="image"><img src="https://cdn-images-1.medium.com/max/896/1*n0OIGV9al5qwIUBaWhOM1Q.png"></figure>Deploying a Library contract<figure class="image"><img src="https://cdn-images-1.medium.com/max/896/1*RQ6hqNGYE-x1MHNnWzqG1w.png"></figure><pre><code class="language-plaintext">npx hardhat deploy ./ignition/ContractWithLibraryModule.js --network buildbear</code></pre><figure class="image"><img src="https://cdn-images-1.medium.com/max/896/1*LpyucSWWgakLfks3bKx_EA.png"></figure>&nbsp;In conclusion, Hardhat-Ignition simplifies the deployment process, allowing you to focus on your projects rather than getting bogged down in the details of deployment execution.&nbsp;<h3>About BuildBear:</h3><a href="https://www.buildbear.io/">BuildBear</a> is a platform tailored for DApp development and testing.
