Simplify Blockchain Development With Powerful APIs

Enterprise-grade blockchain APIs to deploy and manage Smart Contracts, send Ethereum transactions, query blockchain data, and more.
What it is

Comprehensive Blockchain API Toolkit for Simplified Development Across All Skill Levels

The REST API Gateway gives application developers everything they need to focus on their app's business logic and user experience, without getting stuck in the complexities of Ethereum transaction submission, thick Web3 client libraries, nonce management, RLP encoding, transaction signing, and smart contract management.

Just use the intuitive REST APIs generated for you, along with industry standard OpenAPI (Swagger) definitions and management APIs.

Let the REST API Gateway take care of the rest, backed by a fully-managed high throughput Apache Kafka infrastructure. Keep track of your deployed smart contracts, with descriptive names and API documentation, rather than strings of Hex addresses.

Deploy Your First Smart Contract in Seconds

All of the complexities of submitting transactions to Ethereum are handled for you. With one click in the UI you can deploy your first smart contract, then explore that API to send transactions, and read data in a convenient web experience. No special blockchain coding expertise required.

REST APIs for Your On-Chain Logic & Data

OpenAPI (Swagger) definitions are generated for the Solidity Smart Contracts you enable on the REST API Gateway. The Blockchain becomes as simple to code against as any modern web based system. No thick client libraries needed in your app, no complex type mapping. Connect directly from your core applications, or use your existing Integration tier / Enterprise Service Bus (ESB).

Reliable Transaction Streaming, over Apache Kafka

The REST API Gateway handles smart contract compilation, nonce management, RLP encoding and more. It's all backed by the industry standard for reliable ordered streaming of transactions - Apache Kafka. So the same convenient APIs take you from first use, through to enterprise grade production use cases at scale.

Simple Blockchain APIs to Make Development Easier

Kaleido offers enterprise-grade connectivity tailored to your application and back-office system requirements, ensuring high throughput and reliable connectivity to your on-chain smart contracts.

With Kaleido, developers can seamlessly submit transactions to nodes, query chain data, and monitor events. Our platform automatically generates modern REST APIs with comprehensive OpenAPI (Swagger) documentation directly from your Solidity source code, including methods, events, and types. This simplifies development and ensures clarity for developers, with easy access to comprehensive documentation.

For initial usage, Kaleido supports synchronous transaction processing against the chain, ensuring transactions complete smoothly. As you transition to production, leverage our throttling and nonce management features over our Kafka backbone to efficiently stream transactions into the chain. Additionally, developers have direct JSON/RPC access to nodes for smart contract logic development using tools like Truffle or for DevOps activities via a Geth console.

You can manage and deploy your smart contracts effortlessly using Kaleido's blockchain API and user interface. Simply upload your .sol or .zip file containing your Solidity package, and Kaleido generates a REST API that can interact with any on-chain contract with the same Application Binary Interface (ABI). For instance, uploading an ERC20 contract provides an interface capable of querying common data and submitting transactions to any ERC20-based contract. The generated gateway REST API enables deployment of new contract instances with identical configurations, simplifying management through both UI and REST API interfaces.

How the Gateway Handles Scalability and High Transaction Volumes

Kaleido's Gateway leverages cloud infrastructure capabilities for horizontal scaling, meaning it can dynamically adjust resources to meet the demand of transaction loads. Additionally, the gateway optimizes transaction processing and smart contract execution, ensuring high throughput and low latency.

We also offer features like transaction pooling and rate limiting to manage peak loads effectively, ensuring consistent performance even under high demand.

Security Measures to Protect Blockchain Transactions and Data

Security is paramount. Kaleido's API Gateway implements several layers of protection to secure blockchain transactions and data. These measures include HTTPS for secure communication, authentication, and authorization mechanisms to control access, and encryption of sensitive data both in transit and at rest.

The gateway utilizes API keys and OAuth tokens for secure API access, ensuring that only authorized users and applications can interact with the blockchain network.

Integrating with Existing Enterprise Systems

The tool is built with integration in mind, offering a straightforward and flexible approach to connect with existing enterprise systems.

Integration is facilitated through RESTful APIs, which are widely supported across various software and systems, making it easier to embed blockchain functionalities into legacy systems without significant overhaul.

The gateway's API-first design allows it to act as a bridge between blockchain networks and enterprise applications, enabling data exchange and workflow continuity.

For more complex integrations, Kaleido provides documentation and support for custom solutions, including webhooks, event streams, and third-party middleware, to ensure seamless interoperability with a broad range of enterprise ecosystems.
