Best Blockchain APIs for Optimism

A new paradigm for cross-chain experiences that seamlessly connects users with applications. End-users can benefit from the fastest and lowest-cost bridging. Developers can benefit from a streamlined interoperability. Cross-chain Intents are a limit order and an action to be executed. Intents replace explicit steps with user outcomes. This allows relayers to compete for the best execution path. Unlike complex trusted messaging solutions, Across connects users with dapps through intents and not just blockchains to other blockchains. Developers need only embed a standard action in protocol actions to create seamless experiences across chains.

GetBlock is a Blockchain-as-a-Service (BaaS) platform that provides a fast and easy API connection to full nodes from 50+ leading blockchain platforms. It allows you to request information on a node's chain without having to manually set it up with JSON-RPC or REST. This service is ideal for beginners and young entrepreneurs, as well for crypto developers and users. It is also suitable for those who do not have the resources or time to run their own full node. Register an account to get started with GetBlock. You will receive an API key and the relevant data on the dashboard.

QuickNode simplifies blockchain infrastructure for teams big & small. A lightning-fast global API provides instant access to Ethereum, Solana, Bitcoin, Polygon, BSC, Fantom, Avalanche, Terra, Celo, Optimism, Arbitrum, Algorand, Harmony & Gnosis (xDai) networks. Access chain data via JSON-RPC over HTTPS or wss (websocket) endpoints. Monitor usage with analytics dashboard and ship faster with tools like 1-click WebHooks for smart-contract events, NFT, and ERC20 token APIs. Thousands of nodes launched; trusted by top blockchain projects & businesses; QuickNode is helping the blockchain ecosystem grow since 2017!

BlockSpan is an NFT API platform that allows software companies to develop on blockchain technology. We combine data from multiple chains and offer an API layer to enable NFT developers to retrieve token values, current ownership, metadata, and cached images in real-time. It doesn't take much to support multiple blockchains or switch chains. Instead of scraping block logs, you can write a simple rest integration. Our API returns more than transaction data. It also returns price, current owner, metadata and other information. Currently, Ethereum, Polygon and Arbitrum are supported. More will be added in the future. We have extensive documentation that includes an interactive API console for each endpoint. Our NFT API supports token metadata and cached image URLs, saving API and IPFS calls to fetch this data.

Web3 reliability and performance problems can be solved by efficiently utilizing the resources of hundreds third-party node provider combined with a state of the art decentralized blockchain API platform, and an improved user experience. Start building on the most relevant Web3 blockchain projects. Blast aims to provide one of the most resilient and decentralized infrastructure services in the industry and the fastest response time. It uses clustering mechanisms and third party node geographical distribution to assist Web3 developers in obtaining their infrastructure needs covered quickly and allow them to concentrate on the development of applications. Scaling is as simple as allowing more Node providers to join our network. Our protocol enforces good node behavior by conducting periodic checks and applying coercive actions for nodes that fail to perform, such as slashing staked tokens and exclusion from our network.

Web3 indexing is fast and reliable. Real-time, flexible blockchain data APIs. No rate limits, low latency and multi-chain. With seamless access to both on- and offline-chain data, web3 development is simplified. Prices, metadata, and cached token media. Token metadata and pricing feed. Logs and full transaction data. Search for token balances and transactions. Search for addresses, collections, and tokens. Access data defined by your own indexing patterns. For custom endpoints, specify contract ABIs and events. Fast backfill and immediate fill. RESTful endpoints deliver at sub-second latency with zero downtime. Register for on-chain activities that interest you. With nxyz, you can build crypto-powered apps in seconds. To get the fastest API for web3 developers, read the docs. It is possible to scale across billions of users, enabling millions of queries per second.
