ERC-20 RESTful service

ERC-20 RESTful service is a Java and Spring Boot server using web3j to expose REST endpoints for creating and managing ERC-20 tokens through a configured Ethereum or Quorum node.

Practical overview

When it fits

Use it when you have an Ethereum or Quorum node and want a REST and Swagger interface for ERC-20 contract operations instead of making those requests directly to the node.

Who it is for

  • Developers integrating ERC-20 token operations into systems that use REST.
  • Teams operating an Ethereum or Quorum node that need an HTTP interface for token deployment, transactions and state queries.

Documented uses

  • Create and manage ERC-20 tokens through REST requests.
  • Submit transactions against ERC-20 contracts.
  • Query ERC-20 token state through GET requests.
  • Send Quorum private transactions using the `privateFor` header.
Before you choose

Requirements & limits

The repository documents running the server from a JAR with Java 1.8+ or in Docker. It requires a running Ethereum or Quorum node and a sender address already unlocked in the client.

  • The service connects to an existing Geth, Parity or Quorum node; it is not the node itself.
  • Configuration includes the node endpoint and transaction sender address, with a default service port of 8080.
  • The documentation describes Swagger UI for issuing the service’s POST and GET requests.
  • Quorum private transactions use a privateFor header containing a comma-separated list of public keys.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Configure and start the service from a JAR

Build and start the REST service with a configured Ethereum or Quorum node endpoint and sender address.

Before you start

  • Java 1.8 or later
  • An already running Ethereum or Quorum node
  • A transaction address unlocked in the client

Steps

  1. Build the runnable JAR with ./gradlew clean build.

  2. Set nodeEndpoint and fromAddress in application.properties or config/application.properties; the sender address must be unlocked in the client.

  3. Start the JAR with java -jar build/libs/azure-demo-0.1.jar.

  4. Open the Swagger UI at http://localhost:8080/swagger-ui.html to view the documented POST and GET endpoints.

Expected outcome

The service starts with its REST endpoint documentation available in Swagger UI for token deployment, transactions and state queries.

Guide limitations

  • The guide documents configuration and access to the endpoint UI, not a particular successful token operation.
  • The default service port is 8080; the node endpoint and sender address must match the environment.
