Our Services

dApp Development Services

Nine dApp engineering disciplines - from frontend architecture and wallet integration to indexing, gasless transactions and account abstraction - each scoped independently and engineered to enterprise production standards.

dApp dashboard with non-custodial wallet connection, liquidity, governance and staking panels

  • Frontend dApp Development

    We build production React, Next.js and Vue interfaces with type-safe contract bindings, optimistic UI patterns and graceful handling of every wallet, chain and signature edge case.

  • Wallet Integration & Auth

    We integrate WalletConnect, RainbowKit, Web3Modal, embedded wallets and SSO - with signature-based authentication, session management and multi-wallet account models.

  • dApp Backend & APIs

    We engineer Node.js and Go backends for transaction relaying, off-chain computation, signature services and protected mutations - sized for chain throughput, not REST throughput.

  • Indexing & Subgraphs

    We build The Graph subgraphs and custom indexers for fast, queryable on-chain data - with reorg handling, backfill orchestration and multi-chain consolidation.

  • Account Abstraction (ERC-4337)

    We implement bundlers, paymasters and smart wallet integrations for gasless flows, social recovery, batched transactions and session keys - without breaking existing wallet UX.

  • Gasless Meta-Transactions

    We build EIP-2771 forwarders, EIP-712 signature flows and sponsor-pool infrastructure so users transact without holding native tokens - with abuse controls and per-user rate limits.

  • Multi-Chain dApp Architecture

    We engineer dApps that operate seamlessly across EVM and non-EVM chains - with unified state, automatic chain switching and bridge-aware transaction flows.

  • Real-Time On-Chain Data

    We build websocket infrastructure, mempool monitors and event-driven UI updates - with deterministic reconciliation against finalised state to handle reorgs without UI flicker.

  • dApp Performance & Observability

    We instrument client-side performance, RPC reliability, transaction success rates and wallet failure modes - surfacing the operational metrics your product team needs to ship confidently.

  • 220+

    Production dApps shipped across networks

  • 12M+

    Wallet sessions served across deployments

  • 35+

    Chains and L2s integrated in production

Why Bitronix

What Makes Bitronix Different

Not a feature list. Six specific reasons product teams and CTOs choose Bitronix for dApps that must work for every wallet, on every chain, under every network condition.

  • Wallet Edge Case Coverage

    We test against every major wallet, every chain switch failure, every signature rejection path, every nonce conflict. Your dApp doesn't break for the user with the unusual wallet setup - because we've already tested that setup.

  • RPC Resilience By Default

    Every dApp ships with multi-provider RPC failover, retry logic tuned to chain finality and observable health metrics. Your users don't see "Network Error" when Alchemy has an incident - they see continuity.

  • No Black-Box Development

    You see every architectural decision, every test result and every observability output as we build. Your product, security and ops teams get a live documentation trail they can review at any phase.

  • Multi-Chain From the Architecture Up

    We don't bolt multi-chain onto a single-chain dApp. Chain abstraction, transaction routing and state reconciliation are designed in from day one - so adding the next chain is a configuration change, not a rewrite.

  • Post-Launch Operational Coverage

    Most firms ship and disappear. We provide client-side performance monitoring, RPC reliability tracking and incident response with defined SLAs - because the dApp's performance after launch is what your product metrics actually reflect.

  • A Track Record You Can Diligence

    Our case studies are public, our tech stacks are listed and our integrations are named. Read the architecture, check the chains, verify the firms. We give you the evidence to decide, not asks to trust.

Built for Teams Where the dApp Is the Product.

Smart contracts are infrastructure. The dApp is what users actually touch - and what they remember when something goes wrong. A failed transaction, a stuck wallet, a chain reorg that resets state mid-checkout - these are the moments that drive churn. We build for teams who treat the dApp as a production product: with wallet edge case coverage, RPC failover, observable transaction flows and incident playbooks from day one.

Security & Testing Methodology

How We Build dApps That Don't Break In Production.

Most production dApp incidents - failed transactions, stuck wallets, indexing drift, RPC blackouts - are preventable with disciplined engineering. We engineer the preventable ones out so your dApp ships on substance, not luck.

Our methodology is available to review before you engage.

  • Wallet & Chain Matrix Testing

    Before launch, every supported wallet (MetaMask, Rainbow, Coinbase, WalletConnect, Safe, embedded wallets) is tested against every supported chain across every transaction flow. Edge cases - nonce conflicts, chain switching mid-transaction, hardware wallet rejections - are caught before users find them.

  • Signature Flow Hardening

    EIP-712 typed data, EIP-2612 permits and signature-based auth flows are validated against replay attacks, signature malleability and frontrunning vectors. Every signed payload is documented; every signature is bounded by domain separators and deadlines.

  • Reorg & Finality Handling

    Optimistic UI updates are reconciled against finalised chain state. Transaction confirmations respect chain-specific finality (12 blocks on Ethereum, 1 on Polygon, instant on Solana) - so users don't see false confirmations or ghost transactions after a reorg.

  • RPC Reliability Engineering

    Multi-provider failover with health checks, request timeouts and circuit breakers is standard. RPC failures are observable and graceful - degraded reads from cache, queued writes with retry - not blank screens with cryptic errors.

  • Indexing Drift Prevention

    Subgraphs and custom indexers are tested for reorg resilience, backfill correctness and lag monitoring. UI never shows data the indexer hasn't actually finalised - and observable lag metrics surface drift before users do.

  • Performance & Observability Pack

    Every engagement produces a structured handoff: Lighthouse-budgeted bundles, Web Vitals dashboards, transaction success-rate tracking and wallet-failure mode monitoring. Your product team operates the dApp with the same observability rigour as the rest of your stack.

Execution Model

Six Phases, One Accountability Chain.

No handoffs that lose context. The team that scopes your dApp programme ships it and supports it post-launch. Every phase produces a defined artifact - nothing moves forward without it.

  1. Discovery

    Timeline: 3-5 business days

    User flows, wallet strategy, target chains and contract integration boundaries mapped before architecture decisions.

    • Scope document with in/out boundaries
    • Draft user flow specification
    • Chain and wallet selection rationale
    • Contract integration interface map
    • Engagement timeline with phase gates

  2. Architecture

    Timeline: 1-3 weeks

    Frontend architecture, backend topology, indexing strategy and observability plan documented - including rejected alternatives with rationale.

    • Architecture specification
    • Component and route structure
    • Indexing and caching strategy
    • Transaction UX state machine
    • Observability and analytics plan

  3. Development

    Timeline: 4-12 weeks depending on scope

    Frontend components, backend services, indexing infrastructure and contract integrations built with continuous wallet matrix testing and CI-driven performance budgets.

    • Production codebase with type-safe contract bindings
    • Backend services with tests
    • Subgraph or indexer deployment
    • Performance and Web Vitals reports
    • Internal staging matching production topology

  4. Validation

    Timeline: 2-4 weeks

    Wallet matrix testing, signature flow audit, RPC failover validation and accessibility review run before launch. Findings triaged and remediated against agreed severity SLAs.

    • Wallet/chain compatibility matrix report
    • Signature security review
    • RPC failover and load test results
    • Accessibility audit
    • Go/no-go checklist aligned to launch readiness

  5. Launch

    Timeline: 1-2 weeks

    Coordinated frontend deployment, backend rollout, indexer activation and observability go-live against explicit launch criteria - including rollback plans.

    • Frontend deployment record with reproducible builds
    • Backend rollout log
    • Indexer activation confirmation
    • Observability dashboard go-live
    • Post-launch smoke and synthetic test reports

  6. Support

    Timeline: Ongoing - retainer or per-incident

    Client-side performance monitoring, RPC reliability tracking, indexer health, contract upgrade coordination and incident response under defined SLAs.

    • Performance and reliability dashboard
    • Incident response playbook with severity matrix
    • Scheduled upgrade and dependency-update calendar
    • Monthly product-health review (optional retainer tier)
    • Change request process for new flows

Timelines assume responsive client feedback at phase gates. Contract finalisation and audit completion are usually the pacing items for dApp launches - if your contracts are still evolving, expect Validation and Launch to compress against that dependency.

How we partner

Engagement Models

Three ways to engage - structured around how your team works, not how we prefer to sell. Every model operates on the same delivery standard, the same engineering team and the same accountability chain.

01

Dedicated Development Team

3-12 months · 2-5 engineers · Full-time exclusive

Your dApp programme gets a dedicated frontend lead, backend engineer and Web3 integration specialist working exclusively on your product - no context-switching. Suited to full product launches, multi-chain roadmaps and post-launch operational coverage.

Best for: Flagship dApps, multi-chain programmes, teams replacing legacy vendors mid-flight

02

Team Extension

1-6 months · 1-3 engineers · Integrated with your team

We embed with your product and platform teams - working in your repos, design reviews and on-call rotations. You retain UX ownership; we bring wallet matrix depth, indexer expertise and RPC resilience patterns you don't carry in-house yet.

Best for: In-house teams shipping a major release, startups extending a live dApp, enterprises hardening production

03

Project-Based

4-16 weeks · Fixed deliverables · Fixed price

Defined scope and price agreed before work begins. dApp launches, wallet integration sprints, indexing migrations, account-abstraction rollouts and performance hardening engagements are common project-based formats - milestone gates and no billable surprises.

Best for: dApp launches, wallet integration sprints, indexing migrations, RPC and observability upgrades
