We are the first Blockchain as a service provider in LatAm. We offer visionaries and entrepreneurs the ability to create decentralized applications (DApps). These apps interact through JSON APIs which allows our clients to integrate blockchain functionality into their traditional applications. However, some aspects of their products still rely on object-based web development. This is a major breakthrough in blockchain technology because it allows for the use of DApp functionality in traditional applications (both customer facing and internal). These are some of the most common uses for our KNFT product: 1) Smart Contract Management. 2) Decentralized Database Management. 3) NFT-based Identity Authentication 4) Non-fungible token minting. 5) NFT Marketplaces 6) Custom DApps

Our REST API was designed to support real-time use cases and handle massive parallelization. It makes it easy to retrieve data such as NFT Sales, ERC20 token balances, and DEX Swaps. With our SDK, you can quickly access all of this data in your production environment with just a few lines of code. For complete data ingestion flexibility, quickly create more complex queries or transformations. To power more complicated use cases, join across tables. This includes retrieving PnL leaderboards derived form NFT sales data. Smart floor prices for a collection list or the USD-equivalent balance from a wallet's ERC20 assets at any time in history. Serverless snippets can integrate with external data sources to perform transformations that are difficult with direct SQL. Access Transpose directly through your frontend to create powerful production UIs. You can get the data you need as quickly as possible with ultra-low latency queries.

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.

Your NFT application can be brought to market in hours, not months. We handle the NFT infrastructure so that you can concentrate on your application. Built by developers for developers. Grasping Solidity, Web3.js, GraphQL, nodes, IPFS, etc. It is time-consuming, difficult, and often requires a team to cover all the skills. Teams can waste 25-50% engineering resources developing indexers, nodes, and so on. They try to reinvent the wheel. In a highly competitive market, using slow, incomplete, and rate-limited APIs can slow you down, which can lead to revenue loss and users being dissatisfied.

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.

Amazon Managed Blockchain (Amazon Managed Blockchain) is a fully managed service that makes creating and managing scalable blockchain networks easy using the popular open-source frameworks Hyperledger Fabric* and Ethereum*. Blockchain allows you to create applications that allow multiple parties to execute transactions without the need of a central authority. It is difficult to set up and manage a scalable blockchain network using existing technologies. Each member of a network must manually install software, provision hardware, manage access control certificates, and configure networking components. Once the blockchain network is up and running, it is important to monitor it continuously and adapt to any changes such as an increase or decrease in transactions or new members joining the network. Amazon Managed Blockchain can easily scale your blockchain network as the usage of applications on the network grows over time. When a network member requires additional capacity for creating and validating transactions, the member can quickly add a new peer node using Managed Blockchain's APIs.
