Crypto & Web3 software: the big picture
NNT Software develops crypto and Web3 platforms — centralised and P2P exchanges, custodial and MPC wallets, crypto payment gateways, tokenization and smart contracts — with KYC/AML and travel-rule controls built for licensing regimes such as VARA, MiCA, FINTRAC and MAS.
Crypto businesses now operate under formal licensing in many markets, so security, custody and compliance engineering matter as much as trading features.
Challenges crypto & Web3 companies face
- Security incidents that destroy trust
- Licensing requirements that change by country
- Liquidity and scaling at launch
- Complex multi-chain support
What we build for crypto & Web3
Exchanges

Ready-to-customise crypto & Web3 solutions
Crypto Payment Gateway
A crypto payment gateway lets merchants accept Bitcoin, Ethereum and stablecoins such as USDT and USDC, with instant conversion to fiat if required. NNT Software builds white-label and custom crypto payment gateways with merchant dashboards, plugins, payouts, KYT screening and settlement reporting.
NFT & Web3 Marketplace
An NFT or Web3 marketplace lets users mint, buy, sell and trade digital assets on-chain. NNT Software builds marketplaces with wallet login, lazy minting, royalties, auctions, fiat on-ramps and multi-chain support for art, gaming, ticketing and loyalty use cases.
Services we combine
Crypto Exchange Development
Crypto exchange development is building the trading platform, matching engine, wallets and compliance tooling that let users buy, sell and hold digital assets. NNT Software develops custom and white-label spot and P2P exchanges with liquidity integrations, hot/cold wallet architecture, KYC/AML and licence-ready reporting for regulated markets.
Crypto Wallet & Custody Development
NNT Software develops cryptocurrency wallets and custody infrastructure: non-custodial mobile and browser wallets, custodial wallets for exchanges and fintechs, and MPC or multisig custody with policy-based approvals for institutions, supporting Bitcoin, Ethereum, EVM chains, Solana and stablecoins.
Smart Contract Development & Audit
Smart contract development is writing self-executing code that runs on a blockchain. NNT Software builds and reviews Solidity and Rust smart contracts for tokens, DeFi protocols, NFTs, escrow and governance, with full test coverage, gas optimisation, static analysis and preparation for third-party audits.
Typical integrations
- Blockchain nodes — connected through secure, monitored APIs
- Custody providers — connected through secure, monitored APIs
- KYT tools — connected through secure, monitored APIs
- Liquidity providers — connected through secure, monitored APIs
Custom crypto & Web3 software vs off-the-shelf tools
Off-the-shelf crypto & Web3 tools are quick to start but force teams into generic workflows, charge per user and limit integrations. Custom software costs more upfront but fits your exact processes, connects to every system you use, scales without licence fees and becomes an asset you own. Many organisations combine both: packaged tools for commodity functions and custom software for the workflows that differentiate them.
Typical crypto & Web3 projects
Spot exchanges
Order-book trading for major and local tokens.
P2P platforms
Escrow-backed peer-to-peer trading.
Broker apps
Simple buy-sell apps with liquidity providers.
OTC desks
Large trades for institutions.
Crypto & Web3 technology trends
- MiCA and VARA licensing maturity
- Stablecoin payments
- Real-world asset tokenisation
Benefits of custom crypto & Web3 software
Faster launch
A proven core shortens time to market.
Regulator-ready
Compliance controls built in for licensing.
Secure custody
Cold, warm and MPC wallet architecture.
Scalable trading
High-throughput matching engine.
Revenue control
Configurable fees, listings and promotions.
Crypto & Web3 software development cost
The final cost of crypto & Web3 software depends on five main factors: the number of user roles and screens, the integrations required (payments, identity, ERP, CRM, messaging), compliance and security requirements, the seniority mix of the team, and the engagement model.
We always start with a short discovery phase so the estimate you receive is fixed and written, not a vague range. Ongoing maintenance and hosting typically add 15–20% of the build cost per year.
| Scope | Typical timeline |
|---|---|
| White-label exchange | 8–12 weeks |
| Custom spot exchange | 5–8 months |
| P2P platform | 3–5 months |
| Security audit | 3–4 weeks |
Mistakes to avoid when building crypto & Web3 software
- Launching before licensing is clear.
- Keeping too much in hot wallets.
- Skipping independent penetration tests.
- Empty order books with no liquidity plan.
- Weak withdrawal approval policies.

How we deliver crypto & Web3 software projects
Every crypto & Web3 software engagement follows the same disciplined, transparent process. You always know what is being built, what it costs and what comes next.
1. Discovery and scoping (1–2 weeks)
Workshops with your stakeholders to understand goals, users, workflows and constraints. We document requirements as user stories, map integrations and agree success metrics, then share a written scope, milestone plan and fixed estimate for crypto & Web3 software.
2. UX and architecture (1–3 weeks)
Designers produce user flows and a clickable prototype while architects choose the stack, hosting, data model and security controls. Nothing is built until you sign off the prototype and architecture.
3. Agile development (two-week sprints)
Developers build in short sprints with a demo at the end of each one. You see working software early, give feedback continuously and can reprioritise the backlog at any time.
4. Quality assurance
Dedicated QA engineers write test cases, run manual and automated regression tests, check performance and review security basics before every release. Defects are tracked openly.
5. Launch
We deploy with zero-downtime pipelines, migrate data if needed, monitor closely during the first days and train your team or users.
6. Support and growth
After launch, SLA-backed support covers bug fixes, monitoring, security patches and continuous improvement, so the product keeps improving as your business grows.
Engagement models and pricing options
You can engage NNT Software for crypto & Web3 software in whichever way fits your budget, risk appetite and internal team.
| Model | Best for | How billing works |
|---|---|---|
| Fixed price | Clearly defined scope and deadline | Agreed price split into milestone payments |
| Dedicated team | Long-term products and evolving roadmaps | Monthly fee per engineer, scale up or down |
| Time & materials | Exploratory or fast-changing work | Hourly or daily rates against actual effort |
| Hybrid | Fixed MVP followed by ongoing growth | Fixed first phase, then monthly team |
Whichever model you choose, you own the source code and intellectual property, work directly with the engineers, and receive weekly progress reports and demos.
Security, quality and compliance standards
Security and quality are built into every crypto & Web3 software project from the first sprint, not added before launch.

- Encryption in transit (TLS) and at rest, secrets stored in managed vaults
- Role-based access control, multi-factor authentication and audit logs
- Automated tests in CI pipelines, plus manual exploratory and regression testing
- Data-protection by design for GDPR, CCPA, PDPL, DPDP and similar laws
- Infrastructure as code, monitoring, alerting and tested backups
