process

/01

Consultations

At this stage, an initial meeting is held with the client or the customer’s team to clarify the project goals, key requirements, and expectations. Business needs are studied, the problems the project must solve are identified, and possible technologies, architecture, and implementation approaches are discussed.

/02

Planning

At this stage, the following are determined:

Scope of work and key functional modules.
Technology stack, including the choice of a blockchain platform (e.g., Ethereum, Binance Smart Chain, Hyperledger).
Project timeline, including main stages and deadlines.
Resources, including team composition and required tools. The outcome of the stage is a document with the technical specification (TS) and the project roadmap.

/03

Prototyping

An interactive prototype is created to visualize the system’s key functional capabilities. This helps you understand how the project will work in practice. The prototype may include:

Visual representation of user interfaces (UI).
Main interaction flows (user flow).
Smart contract logic.
The prototype is provided for feedback, which helps minimize risks at the next stages.

/04

Design

After the prototype is approved, a full design is developed. At this stage, the following are created:

Graphical interface (UI) taking into account usability (UX).
Brand identity elements, if required.
Design for all platforms, including web and mobile devices.
The main focus is on creating an intuitive interface for users.

/05

Development

Active implementation phase. Smart contracts are programmed, covered with tests, and deployed to testnet. In parallel, backend modules are created to interact with the blockchain, wallets, databases, and third-party service APIs. The frontend part is integrated with Web3, Telegram MiniApp, or mobile SDKs. Development is carried out iteratively with regular reviews, pull requests, and CI/CD pipelines.

/06

Testing and audit

A critical stage that determines the project’s security and trust. Unit, integration, and load tests are conducted. QA specialists check the entire user journey — registration, transactions, deposits, withdrawals, interface errors. Next comes an independent smart contract audit (e.g., CertiK, Hacken, or FreeBlock Audit): vulnerabilities are analyzed, tokenomics logic and attack scenarios are reviewed. Fixes are applied, and a final audit report is issued.

/07

Deployment and infrastructure

After passing tests, the code is prepared for release. Smart contracts are deployed to mainnet, RPC nodes, IPFS, CDN, and API gateways are configured. CI/CD infrastructure is implemented for automated deployment and updates. Monitoring systems (Grafana, Prometheus, Sentry), event logging, and alerts are set up. A domain is registered, SSL certificates are configured, and data backups are arranged. Everything must run without downtime and with rollback capability.

/09

Launch and marketing

The project release is accompanied by a promo campaign. Landing pages, press releases, social media, AMA sessions, and community partnerships are created. Analytics tools (Dune, Mixpanel, Google Analytics) are connected to track user behavior and engagement metrics. If the project has a token, an initial offering (ICO, IDO, fair launch) is conducted with legal and marketing support. The goal is to attract users, investors, and liquidity.

/08

Support and scaling

After launch, the team moves into the support phase. Bugs are fixed, updates are rolled out, and gas costs and performance are optimized. New networks (multi-chain), integrations, modules, and partnerships are added. 24/7 user support is organized. Reports, roadmaps, and progress metrics are published for investors and the community. At this stage, the project becomes a mature product, ready for scaling and attracting large clients.

FAQ

What does FreeBlock do?

FreeBlock is a blockchain and product engineering team. We design and ship smart contracts, DeFi and Web3 products, AI solutions, and custom web and mobile applications for business needs.

Which blockchains do you work with?

We work with EVM networks (Ethereum, BNB Chain, and others), TON, Solana, and other relevant platforms. The chain choice depends on the product: speed, fees, ecosystem, and security requirements.

How long does development take?

Timeline depends on scope and project stage. A focused MVP or a single smart contract often takes a few weeks; a full product with audit, frontend, and integrations can take months. We define milestones upfront and demo every two weeks.

How is pricing calculated?

After a brief we estimate the scope and provide a transparent quote with fixed stage deadlines. You can start with discovery or an architecture audit, then move into full development.

What does the process look like?

From idea to launch: discovery and architecture → development and testing → audit and deployment → support and scaling. We keep regular demos, a clear backlog, and explicit done criteria.

Do you sign an NDA?

Yes. We can sign an NDA before discussing product details. Source code ownership and IP terms are fixed in the contract by agreement.

Do you audit smart contracts?

Yes — we run internal reviews and prepare code for external audits. We help remediate findings, set up roles and upgrades, and ship a secure deployment. See more on our smart contract audit page.

What happens after launch?

We stay for support: bugfixes, updates, gas and performance optimization, multi-chain expansion, and new integrations. You can keep evolving the product with our team.
