Key Features of Infura

Let’s explore these features in more detail.

• Blockchain Infrastructure: Infura offers seamless access to major blockchain networks, including Ethereum, IPFS, and high-performing layer 2 networks. Developers no longer need to manage their own nodes or deal with hardware requirements, as Infura provides managed access to these networks, simplifying the interaction between dApps and blockchain technology. This allows teams to focus on product development instead of infrastructure maintenance.
• Ethereum API: With Infura’s Ethereum API, developers can connect their applications to the Ethereum blockchain with a simple line of code. This removes the need to set up and manage their own Ethereum nodes. By handling the infrastructure, Infura allows developers to build decentralized applications (dApps) or smart contract-based solutions without the technical overhead. The API offers secure and efficient interactions with Ethereum, enabling developers to send transactions, deploy contracts, and query blockchain data.
• IPFS Gateway: Infura also offers a gateway to the InterPlanetary File System (IPFS), a decentralized file storage network. This enhances the storage capabilities of dApps by providing an efficient and distributed way to store and retrieve files. The Infura IPFS gateway ensures high availability and scalability, making it easier for developers to integrate decentralized storage into their applications without the complexities of running an IPFS node.
• Scalability: Infura is designed to scale as your application grows. As your dApp attracts more users and generates more transactions, Infura automatically scales its infrastructure, eliminating the need for developers to manually handle node scaling. This allows teams to focus on building and expanding their products without worrying about maintaining infrastructure for growing traffic.
• High Availability: One of the key strengths of Infura is its high availability, ensuring a 99.9% uptime. This means decentralized applications relying on Infura can have stable and reliable connections to the blockchain networks they depend on. Whether you’re handling transactions or fetching data from the blockchain, Infura’s infrastructure ensures minimal downtime, keeping your dApp functional and responsive.
• Transaction Management: For Ethereum-based dApps, Infura offers Infura Transactions (ITX), a service that helps manage gas fees and transaction submissions. ITX dynamically adjusts gas prices to ensure your transactions are processed efficiently, even during times of network congestion. This feature saves developers time and helps ensure that critical transactions are submitted with the optimal gas price, avoiding costly delays or failures.
• Failover Support for APIs: For enhanced reliability, Infura offers failover support on certain networks for customers on Growth or Custom plans. If one of Infura’s API endpoints becomes unavailable, requests can be forwarded to a partner service to fulfill the request, ensuring that your application remains online and provides uninterrupted service to its users.
• Archive Data Querying: Infura’s Ethereum API offers the ability to query historical state data at any block height. This feature is invaluable for developers needing to access detailed historical data, such as past transactions, smart contract states, or balance information. This makes Infura an excellent choice for developers building data-driven applications or conducting in-depth analyses of blockchain data.
• Expansion APIs: Infura also supports multi-chain expansion, including its Gas API, which is used by wallets like MetaMask to analyze and optimize gas costs on EIP-1559 compatible chains. By integrating Infura’s Gas API, developers can optimize gas fees and make cost-effective decisions for their dApps, further enhancing the user experience by reducing transaction costs and delays.

Infura has become the go-to solution for many blockchain developers looking for a cost-effective and scalable way to interact with the Ethereum network and store data on IPFS.

You don’t have to worry about performance degradation or infrastructure bottlenecks, as Infura ensures your application can handle increasing traffic and transactions.

3. Cost-Effective

Running your own Ethereum node or IPFS gateway is expensive. You need powerful hardware, high storage capacity, and plenty of bandwidth to keep your node synced with the blockchain. Infura eliminates these costs by offering a pay-as-you-go pricing model, where you only pay for the services you use. This makes Infura a cost-effective solution for developers of all sizes.

4. Simpler Transaction Management

Infura offers a service called Infura Transactions (ITX), which helps developers manage Ethereum transactions more efficiently. ITX handles gas prices and ensures that transactions are completed even if they require higher gas fees due to network congestion. This removes the burden of manually managing gas fees, making it easier for developers to build applications that involve frequent transactions.

5. Monitoring and Analytics

Infura provides an interactive dashboard that allows developers to monitor their dApp’s performance in real-time. This dashboard provides insights into API usage, transaction metrics, and other important data that can help optimize application performance. Developers can also use this data to better understand user behavior and improve the overall user experience.

6. Layer 2 Solutions

Infura supports Layer 2 networks like Polygon, Arbitrum Rollup, and Optimistic Ethereum, which are designed to alleviate the congestion issues on Ethereum by processing transactions off-chain. These Layer 2 solutions reduce gas fees and transaction times, making dApps more scalable and user-friendly.
