Cosmos Development Services

Why Partner with Us for Your Cosmos Development Needs?

Our team is adept at handling all aspects of blockchain and application development using the Cosmos SDK framework. This framework, built on the Go programming language, leverages the Inter-Blockchain Communication (IBC) protocol and is powered by the Tendermint Byzantine Fault Tolerance (BFT) consensus engine. As pioneers in the Web3 domain, we utilize this framework to devise the core business logic for industry-specific blockchains and a wide range of decentralized applications (dApps).

Building Decentralized Applications (dApps)

+

Our team of Cosmos dApp developers are skilled at creating dApps for a variety of sectors, including but not limited to, healthcare, finance, and supply chain management. With a deep understanding of the Application Blockchain Interface, our developers can create Cosmos dApps in diverse programming languages.

Designing Decentralized Finance (DeFi) Applications

+

We design open marketplaces and exchange platforms that make it easy for users worldwide to engage in financial activities like buying, selling, investing, and lending.

Developing Smart Contracts

+

We design open marketplaces and exchange platforms that make it easy for users worldwide to engage in financial activities like buying, selling, investing, and lending.

Crafting Digital Wallets

+

We specialize in creating tailor-made digital wallets for iOS, Android, and Web3 platforms on the Cosmos network, compatible with ATOM (Cosmos) tokens. These wallets offer users the convenience of storing multiple digital assets, monitoring their balances, and tracking their transaction history.

Creating Non-Fungible Token (NFT) Marketplaces

+

Our team of Cosmos developers are skilled at building NFT marketplaces that are interoperable, using the IBC protocol or Cosmos SDK. These marketplaces enable users to engage in global NFT transactions without any restrictions.

Providing Cosmos Blockchain Consulting

+

As a provider of Cosmos development services, we work closely with you to determine if the Cosmos blockchain is the right fit for your business needs and how it can optimize your organization's operations.

How does Golang development work?

1

Requirements and architecture

We analyze project needs, design system architecture, choose frameworks and libraries, plan concurrency model, define API structure, establish performance goals, and determine deployment strategy.

2

Core development

We implement business logic, write idiomatic Go code, leverage standard library, create modular packages, implement interfaces, handle errors properly, and follow Go best practices.

3

Concurrency implementation

We utilize goroutines and channels, implement concurrent patterns, manage synchronization, create worker pools, handle race conditions, optimize parallel processing, and ensure thread safety.

4

API and integration

We build REST and gRPC APIs, implement authentication, create middleware, integrate third-party services, establish database connections, handle serialization, and develop client libraries.

5

Testing and benchmarking

We write unit and integration tests, implement table-driven tests, create benchmarks, perform profiling, test concurrent code, validate error handling, and ensure code coverage.

6

Performance optimization

We profile application performance, optimize memory usage, reduce allocations, improve CPU efficiency, implement caching strategies, optimize database queries, and minimize latency.

7

Deployment and monitoring

We build production binaries, create Docker containers, deploy to cloud platforms, implement logging and metrics, set up monitoring dashboards, establish alerting, and provide ongoing maintenance.
