BlockSpan is an NFT API platform for software companies developing on the blockchain. We aggregate data from multiple chains and provide an API layer to allow NFT developers to retrieve token prices, current ownership, and metadata including cached images in real time. Supporting multiple blockchains, or switching chains, doesn't have to be difficult. You can stop scraping block logs and write a simple rest API integration instead. More than just transaction data, our API returns price, current owner, metadata, and more. Ethereum, Polygon, Arbitrum, and Optimism supported today, with more coming soon. We've written extensive documentation for each endpoint that includes an interactive API console. Our NFT API includes token metadata and cached image urls, saving making API and IPFS calls to fetch that data.

Solving Web3 reliability and performance issues by efficiently employing the resources of hundreds of third-party node providers combined with a state-of-the-art decentralized blockchain API platform and an improved user experience. Start building on the most relevant blockchain projects in the Web3 world. Aiming at providing one of the most resilient decentralized infrastructure services and the fastest response times in the industry, Blast is making use of clustering mechanisms and third-party node geographical distribution in order to help Web3 developers in getting their infrastructure needs covered easily and allow them to focus solely on the development of their applications. Scaling is simply done by allowing more Node providers into our network. Good node behavior is enforced within our protocol by performing periodic checks and applying coercive measures for nodes that underperform, like slashing staked tokens or exclusion from the network.

Across offers high speed, low fee interoperability solutions powered by intents. Intents is proving to be a winning solution, as Across dominates the routes its supports, frequently able to provide the cheapest and fastest bridge option. Across' unique value is that it guarantees genuine, not synthetic, assets are transferred cross-chain. With an Across integration, dapps and blockchains are able to provide their users with best-execution cross-chain settlement, without security tradeoffs. Across Protocol offers three products built on a modular, intents-based framework. Across Bridge, which offers high speed, low fee token bridging. Across+, a free chain abstraction tool that allows dapps to onboard users, from any chain, in seconds, for cents. Lastly, Across Settlement, which is a settlement layer that dapps can plug into, to execute intents-based order flow. The future of interoperability are intents, and Across is leading its execution.
