Web3 applications built for real users and real networks.
BitAzure builds decentralised applications end to end: the contracts that hold state, the wallet layer that gets users in, the front-ends they use and the indexing that keeps what they see correct when the chain is busy.
- dApps with injected wallet, WalletConnect and smart-account support
- NFT platforms, DAO tooling and token-gated products
- Gasless and session-based UX via account abstraction
- Web3 identity, attestations and on-chain analytics
What is Web3 development?
Web3 development is the engineering of applications whose core logic, ownership records or identity live on a blockchain, with front-ends and services that let users interact through wallets rather than accounts held by a central operator. It spans smart contracts, wallet connectivity, indexing, identity and the user interface that ties them together.
BitAzure builds Web3 products across that whole span: the contracts that hold state, the React or Next.js front-ends that talk to them, the wallet layer covering injected wallets, WalletConnect and ERC-4337 smart accounts, and the indexing and analytics services that make on-chain activity readable. NFT marketplaces, DAO governance portals, token-gated communities and DeFi front-ends all share this architecture.
What separates a demo from a product is the unglamorous part: transaction simulation before signing, clear states when a chain is congested, reorg-aware data, gas sponsorship where it matters and a codebase your own team can extend.

Reference Web3 application architecture
The front-end reaches contracts through a wallet layer that supports injected wallets, WalletConnect and smart accounts. An identity service handles sign-in and attestations, and an indexer feeds a data API and analytics so the interface never depends on slow, direct chain reads.
Hover or focus a component to see its role in the architecture.
- dApp Front-end (Next.js · wagmi): Wallet-aware UI with transaction simulation, pending states and error recovery.
- Mobile dApp (React Native · deep links): Shares hooks and contract bindings with the web app; connects through mobile wallets.
- Wallet Layer (Injected · WalletConnect): Connector abstraction over browser, mobile, hardware and multisig wallets.
- Smart Accounts (ERC-4337 bundler · paymaster): User operations, gas sponsorship policies and session keys with fallback to standard transactions.
- Identity Service (SIWE · attestations): Sign-In with Ethereum sessions, credential checks and attestation issuance.
- Smart Contracts (NFT · governance · gating): Application contracts with access control, events and upgrade governance.
- Protocols & Oracles (DEX · lending · price feeds): Third-party protocols integrated through audited interfaces with staleness and slippage checks.
- Indexer / Subgraph (Reorg-aware ingestion): Processes contract events into entities and rewinds on chain reorganisations.
- Data API & Store (GraphQL · PostgreSQL): Fast queries for balances, history and metadata; critical values re-verified against nodes.
- Analytics (Dashboards · alerts): Holder, activity and protocol metrics plus event notifications.

What we build with Web3 development
NFT marketplaces and collections
Minting, listings, offers and royalty handling with metadata pinned to IPFS or Arweave.
DAO and governance portals
Proposal lifecycle, delegation and timelocked execution with readable voting history.
Token-gated communities
Access to content, events or software features verified against wallet holdings.
DeFi front-ends
Interfaces for swaps, lending and staking protocols with simulation and slippage protection.
Consumer apps with embedded wallets
Email or passkey onboarding backed by smart accounts so users never handle seed phrases.
On-chain analytics products
Holder, liquidity and protocol dashboards built on custom indexers.
Why teams build Web3 products with BitAzure
UX that survives mainnet
Simulation, pending states and error recovery are designed for real network conditions.
Wallet coverage
Injected, mobile, hardware, multisig and smart accounts supported from one connector layer.
Chain-agnostic architecture
Configuration-driven chain support so a new network is a config change, not a rewrite.
Reliable data
Reorg-aware indexing means the balances and histories users see are correct.
Security in the front-end
Signature request review, domain binding and phishing-resistant patterns are standard.
Maintainable code
Typed contract bindings, generated clients and documented components your team can own.

How we deliver Web3 applications
Every engagement follows a documented, milestone-driven path from discovery to continuous development.
- 01
Product and chain discovery
User journeys, wallet expectations, target chains and data needs are mapped before design starts.
- 02
Contract and interface design
Contract interfaces, access control, events and the front-end data model are specified together.
- 03
Parallel build
Contracts, indexers and the front-end are developed against a local or forked network with shared fixtures.
- 04
Wallet and edge-case testing
Connection flows, rejected signatures, chain switches and congestion scenarios are tested across wallets.
- 05
Security review and launch
Contract review, dependency audit, testnet rehearsal and a staged mainnet rollout.
- 06
Iteration
Analytics-driven improvements, new chains and features delivered by a retained team.
Security practices in Web3 development
Signature safety
EIP-712 typed data with human-readable messages; no blind signing of raw hashes.
Front-end integrity
Content security policy, subresource integrity, pinned dependencies and domain binding for sign-in.
Contract review
Access control, reentrancy, upgrade and token-standard checks with fuzzing before deployment.
Metadata and storage
Immutable metadata pinning and integrity hashes so NFT content cannot be silently swapped.
Sponsored gas controls
Paymaster policies with spending limits, allow-lists and anomaly alerts.
Data validation
Indexed data is cross-checked against nodes; user-facing figures never come from a single source.
We coordinate independent third-party audits on request and never claim an audit, certification or compliance status unless it has actually been obtained.
What to decide before building a Web3 product
Which chains to launch on
User base, fees, wallet support and liquidity differ by network; multi-chain adds cost and complexity.
Self-custody vs embedded wallets
Embedded wallets ease onboarding but move key management responsibility into your stack.
On-chain vs off-chain governance
Off-chain voting is cheap and flexible; on-chain execution is enforceable. Many DAOs combine both.
Metadata permanence
Centralised hosting is convenient but undermines NFT guarantees; IPFS or Arweave pinning has its own operational needs.
Gas sponsorship economics
Sponsoring gas improves conversion but needs budgets, abuse controls and a plan for fee spikes.
Regulatory posture
Token sales, NFTs with financial features and DAO structures may carry legal obligations that shape design.
Web3 Development questions
Blockchain development focuses on networks, nodes and protocols. Web3 development focuses on the applications users touch: wallets, front-ends, NFTs, governance and identity built on top of those networks.
