Value-holding contracts shipped with independent audit
Most blockchain projects fail for reasons that have nothing to do with the blockchain.
Across every category we work in, the same four patterns account for most failed projects. None of them are engineering problems. They are decisions made before development starts, by teams that were not told what they were choosing between.
A vendor with one product to sell
A firm that only builds exchanges recommends an exchange. We work across exchanges, wallets, tokens, DeFi, payments, enterprise networks, and custom chains, so the recommendation follows your problem rather than our inventory.
Technology chosen before the problem
Blockchain earns its place when several parties who do not fully trust each other need shared verifiable records, or when users must own something independently of you. Where neither applies, conventional software is faster and cheaper, and we say so.
Compliance treated as a later phase
Licensing, custody obligations, and reporting shape architecture. Teams that address them after the build discover their platform cannot support what their licence requires. We map regulatory dependencies in week one.
Handover that never happens
Many vendors retain the code, take a share of revenue, or keep admin keys. Every engagement we run transfers full source, infrastructure, and contract ownership to you, with no retained access and no revenue share.
Our Blockchain Software Development Services
Nine practice areas covering public and permissioned networks. Each links to the detail.
A blockchain software development company provides architecture and feasibility assessment, smart contract development, application and interface development, wallet and custody infrastructure, exchange and trading systems, token and NFT development, payment and settlement infrastructure, enterprise and permissioned networks, security auditing, deployment, and ongoing maintenance.
Crypto Exchange Development
Centralized, decentralized, hybrid, peer-to-peer, and derivatives trading platforms, with matching engines, custody, liquidity, and compliance built in.
Crypto Wallet and Custody Development
Custodial, non-custodial, and MPC wallets across mobile, web, and browser extension, plus institutional custody with governance and approvals.
Token, Launchpad and NFT Development
Utility, governance, security, and stablecoin tokens with tokenomics and vesting, token launch platforms, and NFT collections, marketplaces, and utility applications.
DeFi Protocol Development
AMMs and DEXs, lending markets, staking and liquid staking, yield vaults, and on-chain derivatives, with economic attack modelling alongside code audit.
Crypto Payments and Banking Infrastructure
Merchant payment gateways with crypto to fiat settlement, and core banking platforms running fiat and digital assets on one ledger.
Blockchain Game Development
Games with player-owned assets, sustainable economies, in-game marketplaces, and onboarding that requires no wallet or gas token.
Enterprise and Permissioned Blockchain
Consortium and private networks on Hyperledger Fabric, Besu, Corda, and Quorum, with governance design and integration to existing systems of record.
Custom Blockchain and Protocol Development
Layer 1 chains, application-specific chains, Layer 2 rollups, and sidechains, with consensus, validator, and economic design.
Smart Contracts, dApps and Trading Systems
The engineering layer underneath everything above: audited smart contracts, full-stack decentralized applications, and automated trading systems.
Not sure which of these you need?
Most enquiries start here. Tell us the business problem rather than the technology, and we will tell you which approach fits, or that a conventional solution serves you better. We offer advisory as a paid standalone engagement if you want the answer before committing to a build.
Three ways to work with us
Engagements are scoped and priced before they start, whichever route you take.
Advisory and Feasibility
Duration
2 to 10 weeks
Strategy, feasibility, platform selection, architecture review, or technical due diligence, delivered as a written recommendation you own, with no obligation to build with us.
Best for:
Organisations that need a defensible answer before committing budget.
Includes:
Discovery, analysis, written recommendation, and presentation to your stakeholders.
Full Product Build
Duration
8 weeks to 18 months
Design, architecture, development, audit, deployment, and launch, delivered as a fixed scope with a fixed price and full handover.
Best for:
Teams with a defined product to build.
Includes:
Architecture, development, security audit, deployment, documentation, training, and handover.
Retained Engineering
Duration
Ongoing retainer
A retained team maintaining and extending a live product: features, new chains, infrastructure, monitoring, and incident response.
Best for:
Live products needing sustained capacity without hiring.
Includes:
Agreed monthly capacity, a named technical lead, and defined response times.
A proven blockchain development process, from problem to production
Five stages. The first can end the engagement, and sometimes should.
Problem and Feasibility
We define the business problem, test whether distributed ledger technology genuinely improves on the alternative, and map regulatory dependencies. output: a recommendation, including a recommendation against where appropriate.
Architecture and Scope
Technology and network selection, system architecture, security and custody design, and a fixed-price scope with a realistic timeline. output: an architecture document, a cost model, and a scope you can hold us to.
Build and Integration
Development across contracts, applications, and infrastructure, with integration to the third parties and internal systems the product depends on. output: a working product in a staging or test environment.
Audit, Testing and Acceptance
Independent security audit on anything holding value, penetration testing, load testing, and structured user acceptance testing with your team. output: audit reports, a remediation log, and a signed-off release candidate.
Launch, Handover and Support
Production deployment, monitoring and alerting, team training, and full transfer of source, infrastructure, and contract ownership. output: a live product your team can operate, with support available if you want it.
Get an honest assessment before you commit budget
A 45-minute call covering what you want to build, whether blockchain is the right instrument, what it realistically costs, and how long it takes. No obligation, no sales script, and we will tell you when the answer is a conventional solution or another vendor.
- Whether your problem genuinely calls for distributed ledger technology
- Which approach fits your market, users, and regulatory position
- A realistic timeline and cost, including the dependencies that usually cause delays
Key Benefits of Working With Pixel Web Solutions
What clients get from a firm that works across the whole category rather than one product.
Recommendations not tied to one product
We build across exchanges, wallets, tokens, DeFi, payments, games, enterprise networks, and custom chains, so the recommendation follows your problem.
Willing to say no
We have advised organisations to use a conventional database, to deploy on an existing chain rather than build one, and not to proceed. An adviser who cannot say no is only providing agreement.
Security audited as standard
Independent audit on anything that holds or controls value, with penetration testing and a published remediation log, rather than sold as an upgrade.
Compliance-aware architecture
Licensing, custody, and reporting requirements mapped before architecture, so the platform supports what your regulatory position actually requires.
Fixed scope and fixed price
Engagements are scoped and priced before work begins, with the dependencies that typically cause delay identified upfront.
You own everything
Full source code, contracts, infrastructure, and data transfer to you, with contract ownership moved to your control. No revenue share, no per-user fees, no retained admin access.

Which blockchain service does your problem need?
Blockchain development covers distinct disciplines that share a technology but little else. Exchanges need matching engines and liquidity. Wallets need key management. Tokens need economic design. Enterprise networks need governance. The right starting point is the business problem, not the technology, and most projects need one of these rather than several.
| If your goal is | The service you need | Typical timeline |
|---|---|---|
| Let users trade crypto | Crypto exchange development | 8 weeks to 18 months |
| Let users hold and move assets | Crypto wallet development | 6 to 16 weeks |
| Issue your own token | Token development | 2 to 20 weeks |
| Run token sales for other projects | Launchpad development | 6 to 10 weeks |
| Build a financial protocol | DeFi protocol development | 10 to 20 weeks |
| Sell or trade digital collectibles | NFT development | 3 to 20 weeks |
| Accept crypto from customers | Payment gateway development | 10 to 16 weeks |
| Offer accounts, cards and custody | Crypto banking software development | 16 to 44 weeks |
| Give players ownership of game assets | Blockchain game development | 12 weeks to 18 months |
| Share records between organisations | Enterprise blockchain development | 12 to 24 weeks |
| Run your own network | Custom blockchain development | 12 weeks to 18 months |
| Automate a trading strategy | Trading bot development | 6 to 24 weeks |
| Decide whether to do any of this | Blockchain consulting | 2 to 10 weeks |
How to evaluate any blockchain development company
Including us. These are the questions that separate firms that ship from firms that pitch, and you should ask all of them before signing with anyone.
| Question | What a good answer sounds like | What should concern you |
|---|---|---|
| Will you tell us if we do not need blockchain? | Specific examples of advising against it | Enthusiasm for every idea presented |
| Who owns the code and infrastructure at the end? | Full transfer, no retained access, in writing | Revenue share, retained keys, or platform licensing |
| Is security audit included or extra? | Included for anything holding value, by an independent firm | Audit as an optional upgrade, or self-certified |
| What happens after handover? | Documented runbook, training, optional retainer | Support only available through them, indefinitely |
| Have you deployed this exact thing to production? | Named work, or a candid no with relevant adjacent experience | Vague claims that do not survive a follow-up question |
| Who reviews the regulatory position? | Requirements mapped for your counsel, no legal advice offered | Assurances that a licence is not needed |
| What is not included in the price? | A clear list: audit, infrastructure, licensing, third parties | A single figure with no breakdown |
| Can we speak to a client who left? | Yes, or an honest explanation | Only curated references |
We publish this because we would rather be chosen by someone who asked than by someone who did not.
Ask us all eight on the scoping call. We would rather answer them early.
