Simplifying Payment Integration with Cartesi Payments API: A Guide for Developers

Cartesi is a blockchain-based platform that allows developers to create decentralized applications (dApps) with ease. It is designed to solve some of the problems that developers face when building dApps, such as scalability and high transaction fees. Cartesi’s payments API is one of the key features of the platform, and it makes it easy for developers to accept CTSI payments on their dApps.

In this article, we will explore how to build on Cartesi, why developers should consider using the platform, and how to use NOWPayments’ API to simplify payment integration. We will also discuss the different types of payment APIs available, including mass payouts and extended custody, and how to test them in the sandbox environment.

Cartesi Overview

Cartesi is a layer-2 solution that allows developers to create dApps with a familiar development environment, such as Linux. It uses a unique approach to scaling that involves off-chain computation and on-chain verification. This approach makes it possible to create dApps that can handle large amounts of data and complex computations without incurring high gas fees.

One of the key benefits of using Cartesi is that it allows developers to build dApps in a language they are familiar with, such as C++. This makes it easier for developers to get started with building dApps on the platform. Additionally, Cartesi allows developers to use off-chain computation to perform complex tasks, such as machine learning, which can be difficult or impossible to do on-chain.

How to Build on Cartesi and Why

Building on Cartesi is a straightforward process that involves setting up a development environment and writing smart contracts. Cartesi provides a range of development tools and documentation to help developers get started, including a software development kit (SDK), tutorials, and sample projects.

Developers should consider using Cartesi because it provides a scalable and flexible platform for building dApps. With Cartesi, developers can create dApps that can handle large amounts of data and complex computations without incurring high gas fees. Additionally, Cartesi’s approach to off-chain computation makes it possible to handle tasks that would be difficult or impossible to do on-chain.

Projects Built on Cartesi

Several projects have been built on Cartesi, including games, finance, and NFT marketplaces. For example, Creepts is a tower defense game that uses Cartesi’s off-chain computation to handle game logic and AI. Another project, Deca4, is a decentralized exchange that uses Cartesi to handle large amounts of data and complex computations.

NOWPayments API Overview

NOWPayments is a cryptocurrency payment gateway that allows merchants to accept crypto payments. It provides a range of APIs, including a Payments API, Mass Payouts API, and Extended Custody API. These APIs make it easy for developers to integrate crypto payments into their dApps.

Testing API in Sandbox

NOWPayments provides a sandbox environment that developers can use to test their APIs before deploying them to production. The sandbox environment allows developers to test their APIs using mock data, which ensures that their APIs are working correctly before deploying them to production.

NOWPayments API with Cartesi
