The world of blockchain development thrives on innovation, collaboration, and powerful tools. Many leading platforms in the space contribute to this growth by open-sourcing critical software development kits (SDKs), documentation, and core infrastructure. This approach empowers developers to build more secure, efficient, and interoperable applications. One significant contributor to this open-source landscape offers a suite of resources that cater to a wide range of development needs across multiple blockchains.
This article provides an overview of some key open-source projects available, focusing on their functionality and potential use cases for developers.
Core Developer Tools and SDKs
A strong foundation is essential for any developer. The following tools provide the building blocks for creating robust Web3 applications.
Multi-Chain Signature SDKs
Interacting with multiple blockchains often requires different tools for each. Multi-chain SDKs solve this problem by providing a unified interface for generating transactions and signatures across various networks.
- Go Wallet SDK: This is a comprehensive Golang library that supports a wide array of blockchains, including Bitcoin, Ethereum, Solana, and TON. It simplifies the process of transaction signing and wallet management for backend services and infrastructure projects.
- JavaScript/TypeScript Wallet SDK: For front-end and Node.js developers, this SDK offers similar multi-chain functionality. It supports major chains like Bitcoin, Ethereum, Solana, and Cosmos, enabling the creation of web wallets, dApp interfaces, and server-side transaction processors.
These SDKs are invaluable for projects that aim to be chain-agnostic, allowing users to interact with assets on their preferred network seamlessly.
Threshold Signature Scheme (TSS) Library
Security is paramount in crypto. The Threshold Signature Scheme library provides a sophisticated cryptographic solution for securing digital assets. It enables a 2-of-n signature scheme for both ECDSA (used by Bitcoin and Ethereum) and Ed25519 (used by Solana and others) curves. This means a private key can be split among multiple parties, and transactions only require a threshold of signatures (e.g., 2 out of 3) to be executed. This enhances security by eliminating single points of failure and is ideal for institutional custody, multi-signature wallets, and secure transaction orchestration.
Blockchain Infrastructure and Networks
Beyond SDKs, contributing to core blockchain infrastructure is a major step towards fostering ecosystem growth.
OKTC (OKB Chain)
OKTC is a Layer 1 blockchain network built using the Cosmos SDK. It is designed with a strong emphasis on interoperability and high performance. Key features include:
- EVM & Wasm Compatibility: It supports both Ethereum Virtual Machine (EVM) and WebAssembly (Wasm), allowing developers to port existing Ethereum smart contracts or build new ones in various languages.
- IBC Integration: As part of the Cosmos ecosystem, it leverages the Inter-Blockchain Communication (IBC) protocol, enabling seamless asset and data transfer between other IBC-enabled chains.
- This infrastructure provides a scalable and connected environment for deploying decentralized applications.
XLayer Network and Documentation
XLayer is a Layer 2 scaling solution. Its public documentation repository is a critical resource for developers looking to build on or interact with the network. Comprehensive docs are essential for understanding network specifics, smart contract deployment, bridge functionality, and API integrations.
Additional Development Resources
The ecosystem includes several other repositories that support various aspects of development and operations.
- Proof of Reserves: An implementation for proving reserves transparently, a key component for building trust in centralized and decentralized services.
- DEX Widget: A configurator sample for embedding decentralized exchange (DEX) functionality directly into other websites or applications.
- Infrastructure & CDK Tools: Various tools written in Go for managing blockchain infrastructure and providing a development kit for building on top of XLayer.

Frequently Asked Questions
What is a multi-chain SDK and why is it useful?
A multi-chain SDK is a software development kit that allows developers to interact with multiple different blockchains using a single, unified codebase. This is incredibly useful because it eliminates the need to learn and integrate a separate library for each blockchain, significantly speeding up development time and reducing complexity for applications that support users on various networks.
How does a Threshold Signature Scheme (TSS) improve security?
TSS improves security by decentralizing the control of a private key. Instead of one key being stored in a single location, it is split into multiple "shares" distributed among different parties or devices. A transaction requires a predetermined number of these shares (e.g., 2 out of 3) to create a valid signature. This protects against a single point of failure, such as a compromised device or a malicious insider.
What is the difference between a Layer 1 and a Layer 2 blockchain?
A Layer 1 (L1) is the base blockchain network itself, like Bitcoin or Ethereum, which handles security, consensus, and data availability. A Layer 2 (L2) is a separate protocol built on top of an L1 to improve its scalability and speed. L2s process transactions off-chain and then post finality data back to the L1, inheriting its security while being faster and cheaper to use.
Why is open-source software important for blockchain development?
Open-source software is fundamental to blockchain because it ensures transparency, trust, and collaboration. Anyone can audit the code for security and fairness, developers can freely build upon existing work to innovate faster, and the community can collectively improve the tools, leading to more robust and secure ecosystems for everyone.
What does EVM compatibility mean for a developer?
EVM compatibility means a blockchain can execute smart contracts written for the Ethereum Virtual Machine. For developers, this allows them to deploy their existing Solidity-based smart contracts from Ethereum to the compatible chain with minimal changes, giving them access to a new user base and often a cheaper, faster network.
How can I get started using these developer tools?
The best way to get started is to visit the official GitHub repositories for the projects that interest you. These repos typically contain detailed README files, code examples, and comprehensive documentation to guide you through the installation and implementation process. 👉 Find resources to start building
