It’s funny how a seemingly meaningless event in one’s life can lead to an unexpected change. For me, one of those events happened in July 2021 when my flight home was delayed by so much that I paid for my very first Uber. For this article, I wanted to see how easy it is for a web2 developer to use Java in order to perform some Fintech transactions using web3 and USDC over the Ethereum blockchain. My plan is to use the Circle Java SDK, Java 17, and a Spring Boot 3 RESTful API. By John Vester.
USD Coin (USDC) is a digital currency that is fully backed by U.S. dollar assets. USDC is a tokenized U.S. dollar, with the value of one USDC coin pegged 1:1 to the value of one U.S. dollar. The value of USDC is designed to remain stable, making USDC a stablecoin.1
The article then describes:
- About Circle and USDC
- Using USDC to make and receive payments with Java? Yes, please!
- Creating a Spring Boot service
- Externalizing Circle configuration
- Adding a Circle integration service
- Creating RESTful URIs
In the article author was able to leverage Java and Spring Boot to integrate a RESTful API into the Circle platform and start making real-time, online, secure payments. All code together with explanation is attached. Good read!
