Blockchain Development
For four years as CTO of Build My Dapp I owned web3 delivery end to end: smart contracts, the Node.js APIs around them, wallet and API integration, frontends and design. I also teach this stack, Solidity, Solana and Ethereum, as a trainer at PIAIC and Edversity. You get contracts that are secure and readable, and a product around them that people can actually use.
What you walk away with
- ✓Smart contract architecture and implementation in Solidity (EVM) or Rust (Solana)
- ✓Access control, allowlists, transfer limits and auditable admin actions enforced in the contracts
- ✓Node.js API layer for off-chain data, indexing and third-party integrations
- ✓Dapp frontend with wallet connection and clear transaction flows
- ✓Security audit readiness package — test coverage, static analysis, formal verification scope
- ✓Handoff documentation and a hands-on training session for your developers
Engagement model
01
Architecture & Compliance Mapping
Protocol Design
2–3 weeks. Define the blockchain architecture, compliance requirements, and technical trade-offs. Includes regulatory mapping.
02
Smart Contracts & Policy Layer
Core Build
8–16 weeks. Core protocol implementation — smart contracts, compliance hooks, risk scoring, and governance mechanisms.
03
System Integration & Audit Prep
Integration
4–8 weeks. Connect the contracts to your APIs, wallets and frontend. Prepare for an independent security audit.
04
Deployment & Monitoring
Launch
2–4 weeks. Mainnet or testnet deployment, monitoring setup, incident response runbooks, and team knowledge transfer.

Frequently asked questions
- What is enterprise blockchain development?
- Enterprise blockchain development is the practice of building permissioned or hybrid blockchain systems for institutional and regulated business contexts — including supply chain traceability, DeFi compliance rails, trade finance automation, and tokenised asset issuance. Unlike public blockchain projects, enterprise blockchain development prioritises compliance controls, audit trails, integration with existing systems, and governance mechanisms over token speculation.
- What are the best enterprise blockchain development services?
- The best enterprise blockchain development services combine solid smart contract engineering (Solidity, Rust) with everything around the contract that a business needs — access controls, transfer limits, auditable admin actions, reliable APIs and a frontend people can use. Mudassir Khan spent four years as CTO of Build My Dapp shipping smart contracts and dapps for clients, and trains developers in Solidity and Solana.
- Which blockchains and protocols do you work with?
- My primary experience is Solidity on Ethereum and EVM-compatible chains, which I shipped for clients as CTO of Build My Dapp, and Solana, which I teach alongside Ethereum in a full-stack Web3 curriculum at Edversity. I choose the chain based on your users, fees, throughput needs and the ecosystem you already live in.
- Can you build a DeFi product that passes regulatory scrutiny?
- Yes. The key is designing compliance into the protocol from Day 1, not as a wrapper on top: allowlists, transfer limits and auditable admin actions enforced by the contracts themselves. I spent four years as CTO of Build My Dapp shipping smart contracts and dapps for clients, and I teach Solidity and Solana development as a Web3 trainer.
- Do you do smart contract security audits?
- I prepare smart contracts for third-party security audits rather than performing the audits myself (audits should be independent). This includes: full test coverage, static analysis with Slither and Mythril, manual review for common vulnerability patterns, and a written findings report. I work with your preferred audit firm or can recommend one.
