What We Build
Step-by-Step
Web3 Development Process
A structured delivery process reduces risk and keeps Web3 projects predictable. We deliver in milestones with demos, acceptance criteria, and production readiness as a standard outcome.
Discovery & Use Case Validation
We define goals, constraints, and success metrics so the build stays aligned with business outcomes. This helps avoid scope drift and reduces wasted effort.
MVP Build (Core Modules)
We implement core modules first to validate product-market fit and operational requirements. MVP delivery is designed to be launchable, not a temporary prototype.
QA, Security Testing & Audit Prep
We test end-to-end user flows and security-critical behaviors under realistic conditions. Audit preparation includes documentation and code structure for efficient review.
Architecture & Threat Modeling
We design the system architecture and threat-model critical flows before implementation. This step prevents security gaps and expensive redesigns later.
Integrations (Wallets, Bridges)
We integrate the components your product needs, such as wallets, oracles, bridges, and payment rails. Integrations include monitoring and stable error handling for production operation.
Launch, Monitoring & Iteration
We launch with monitoring, operational dashboards, and incident response workflows. Post-launch work focuses on scaling, feature expansion, and continuous improvement.
Our Web3 development lifecycle is built on a "Security-First" engineering culture, transitioning from rigorous mathematical modeling of smart contracts to automated mainnet deployment. We utilize industry-standard frameworks like Foundry and Hardhat for iterative testing, combined with property-based fuzzing to identify edge-case vulnerabilities before the first line of code hits the blockchain. By implementing CI/CD pipelines for dApps and integrating decentralized storage solutions (IPFS/Arweave) from the architectural phase, we ensure that your protocol is not only functional but truly decentralized and audit-ready.
Stack
Tech Stack & Ecosystems
Intro
We work across leading Web3 ecosystems and choose tools based on product goals, cost, security, and developer maturity. Tech choices are made to keep systems maintainable and scalable over time.
Infrastructure & DevOps
We build DevOps pipelines, monitoring, and release processes for safe production operation. Infrastructure is designed for observability, reliability, and cost control.
EVM Chains (Ethereum, etc.)
We build on EVM chains when you need strong ecosystem tooling and broad adoption. Chain selection is guided by fees, liquidity, and user distribution.
Non-EVM (Solana, etc.)
We build on non-EVM ecosystems when performance and specific ecosystem fit are priorities. Architecture is adapted to chain-specific standards and tooling.
Wallets & Account Abstraction
We integrate wallet standards and account abstraction patterns when required to improve onboarding and UX. This supports features like social login, session keys, and safer signing flows.
Oracles, Indexers, and Data Tools
We integrate oracles and indexing tools to ensure accurate pricing and responsive UI data. Data tooling supports analytics, monitoring, and reliable event processing.
Architecture
Web3 Architecture We Deliver
We design Web3 architecture in modular layers so smart contracts, indexing, UI, and infrastructure can scale independently. This approach improves reliability, reduces risk, and supports faster iteration without destabilizing core logic.
01
Smart Contract Layer (Solidity/Rust)
We implement smart contracts using appropriate standards and secure design patterns based on your product type. Upgrade strategy is defined upfront to balance flexibility with trust and auditability.
02
Security Layer (Threat Modeling)
We threat-model critical flows and implement controls to reduce attack surfaces and misuse. Testing includes edge cases and adversarial scenarios to increase production safety.
03
Data Layer (Indexing, Events)
We build indexing and event processing so your dApp can display fast, accurate on-chain states. Analytics and data pipelines support dashboards, monitoring, and product insights.
04
Web3 Frontend (Wallet UX, Signing)
We design wallet interactions that make signing, confirmations, and errors clear to users. UX is optimized for conversion while maintaining safe transaction prompts.
Infrastructure Layer (Nodes/RPC, Monitoring, CI/CD). We set up node connectivity, deployment pipelines, and monitoring for stable operation. Infrastructure is designed for reliability, observability, and safe releases.
Cost
Cost of Web3 Development
The cost of Web3 development is primarily driven by the complexity of the on-chain logic and the required level of protocol interoperability. Developing a standalone DeFi development company primitive or an NFT collection requires a different resource allocation than building a cross-chain ecosystem with custom bridges and complex DAO governance. Key cost drivers include smart contract optimization (to minimize gas fees for end-users), the integration of decentralized oracles (like Chainlink), and the development of a secure, non-custodial frontend.
Cost Estimates
Crypto Exchange: $20,000 - $150,000
Crypto Wallet: $25,000 - $150,000
Tokenization Platforms: $10,000 - $150,000
Security audits represent a mandatory investment in the Web3 space. For projects targeting the US market, having a multi-layered audit from reputable firms is essential for building investor trust and ensuring the safety of TVL (Total Value Locked). Additionally, building a robust backend for indexing blockchain data (using The Graph or custom Subgraphs) adds to the initial investment but is critical for providing a seamless, "Web2-like" user experience in a decentralized environment.
A production-ready Web3 platform typically ranges from $30,000 to $90,000, depending on the architecture and auditing requirements
