How We Work

Clear process. Predictable delivery. Real results
01

Agile Planning (First 3-4 weeks)

Before writing a single line of code, we align on everything that matters - from product vision to production-ready blockchain architecture.

  • Storyboarding & user journey mapping
  • Technical discovery and architecture design (EVM / non-EVM blockchains)
  • Tokenomics validation and smart contract architecture
  • UI/UX prototyping for your Web3 application or dashboard
  • Agile estimation and team setup
  • Proof of concept or testnet deployment (if needed)

Outcome: a clear delivery plan, realistic timeline, and confidence that your blockchain MVP or protocol module is built on solid technical foundations.

02

Sprint Delivery (Every 2 Weeks)

Each sprint brings measurable progress - and a UAT-ready blockchain build.

  • Sprint planning & backlog prioritization
  • Design and smart contract development (Solidity / Rust)
  • Integration with blockchain oracles, wallets, and cross-chain bridges
  • Manual and automated QA testing
  • Internal review + client demo
  • Deployment to testnet or mainnet-ready blockchain environment

Outcome: working software every sprint - whether it’s a DeFi protocol, NFT marketplace, or enterprise blockchain module.

03

Post-Launch Support

We stay with you after release to ensure long-term reliability and scalability.

  • Continuous monitoring of on-chain activity, nodes, and smart contracts
  • Critical issue resolution and incident response
  • DevOps, infrastructure & CI/CD pipeline management
  • Product and roadmap planning for new features
  • Emergency response for protocol, validator, or bridge security events

Outcome: your Web3 product stays secure, stable, and ready to scale.

04

Continuous Improvement

We continuously refine both the product and the process.

  • End-of-sprint demos and retrospectives
  • Backlog grooming with your input
  • Regular status reports and roadmap reviews
  • Smart contract and infrastructure optimization cycles

For us, working blockchain software and measurable outcomes are the only KPIs that matter - not hours logged.

Frequently asked Questions

1.
What does your software development lifecycle (SDLC) include?
Our SDLC covers discovery and architecture, implementation, testing, deployment, and post-launch support. Each phase is designed to reduce risk, ensure quality, and make progress visible - from early technical decisions to production releases.
1.
Do you provide quality assurance and testing support?
Yes. Quality assurance is part of every project. We provide functional testing, integration testing, and performance checks for smart contracts, backend services, and user-facing applications before deployment to testnet or mainnet.
1.
Can you manage security, compliance, and infrastructure for Web3 products?
We design systems with security and compliance in mind from the start. This includes secure architecture, infrastructure setup, monitoring, and support for regulatory or operational requirements relevant to Web3 and blockchain-based products.
1.
How is your blockchain development process structured?
We follow an Agile delivery process adapted for Web3. Projects usually start with a 3–4 week planning phase covering architecture, scope, and risks. Development then runs in bi-weekly sprints with clear deliverables, progress updates, and testable builds at each stage.
1.
Which blockchains and technology stacks do you support?
We work across both EVM and non-EVM ecosystems, including Ethereum, Polygon, BNB Chain, Avalanche, Solana, NEAR, Cosmos SDK, and Polkadot. Our teams also build Layer-2 solutions and implement cross-chain communication using protocols such as LayerZero, CCIP, and Wormhole.
