Custom blockchain development services
Blockchainthatsolvesrealbusinessproblems—notjusttechnologytheatre
Too many blockchain projects are built around the technology instead of the problem. At Smoking Chimney, we start with your business challenge — then determine whether blockchain is the right tool, which chain fits best, and how to deliver maximum ROI from your investment.
What we build
End-to-endblockchaindevelopmentcapabilities
Smart Contract Development
Secure, gas-optimised smart contracts on Ethereum, Polygon, BNB Chain, Solana, and other EVM and non-EVM chains — from simple token contracts to complex multi-party agreements.
- Solidity & Rust development
- Gas optimisation
- Formal verification
- Multi-sig & time-lock patterns
Private Blockchain Networks
Design and deploy permissioned enterprise blockchain networks using Hyperledger Fabric, Besu, or custom consensus mechanisms tailored to your consortium's governance model.
- Hyperledger Fabric networks
- Ethereum Besu (private)
- Custom consensus design
- Multi-org governance models
DeFi & Token Development
Build DeFi protocols, governance tokens, utility tokens, NFT platforms, and tokenised asset systems with security-first smart contract architecture.
- ERC-20 / ERC-721 / ERC-1155
- AMM & liquidity pools
- DAO governance systems
- Tokenised real-world assets
Blockchain System Integration
Integrate blockchain infrastructure into your existing enterprise systems — ERP, supply chain platforms, banking systems — via REST APIs, event listeners, and oracle networks.
- Oracle integration (Chainlink)
- Cross-chain bridges
- ERP & CRM connectors
- Blockchain data indexing
Blockchain PoC & MVP Development
Validate your blockchain concept quickly and cheaply with a focused proof-of-concept or MVP — before committing to full-scale production development.
- 2–4 week PoC sprints
- Testnet deployment
- Investor-ready demos
- Architecture validation
Smart Contract Audit & Security
Independent security review of existing smart contracts — identifying re-entrancy vulnerabilities, integer overflows, access control issues, and other critical exploits before they cost you.
- Manual code review
- Automated vulnerability scanning
- Attack vector analysis
- Remediation support
Why Smoking Chimney

Multi-chain expertise
We're not a one-chain shop. Our engineers have shipped production systems on Ethereum, Polygon, BNB Chain, Solana, Avalanche, and Hyperledger Fabric — so we choose the right chain for your use case, not the one we know best.
Security-first smart contracts
Every smart contract we write goes through internal security review and automated scanning. For high-value contracts, we recommend and coordinate external audits from top-tier firms.
Enterprise blockchain track record
We've delivered blockchain solutions for supply chain provenance, trade finance, digital identity, and tokenised assets — building credibility with enterprises that can't afford blockchain experiments.
Pragmatic blockchain consulting
We'll tell you honestly when blockchain adds value and when it doesn't. Our consulting engagements start with problem-first thinking, not technology evangelism.
How we deliver

Blockchain feasibility & chain selection
We assess your use case, identify whether blockchain genuinely adds value over a traditional database, and select the optimal chain (public vs. private, EVM vs. non-EVM) based on your requirements.
Architecture design & tokenomics
System architecture, data models, on-chain vs. off-chain data partitioning, smart contract interfaces, and (where applicable) token economic design are all defined before development begins.
Smart contract development & testing
Contracts are developed with test-driven development, tested on local hardhat/foundry environments, and deployed to testnets for multi-stakeholder review before mainnet.
Backend & integration layer
We build the indexing, API, and event-listening backend that makes your blockchain data accessible to your applications and enterprise systems in real-time.
Frontend dApp or enterprise dashboard
User-facing applications — whether a Web3 dApp with wallet connection or an enterprise admin dashboard — are built with your end-users' technical sophistication in mind.
Audit, deployment & monitoring
Smart contracts undergo security review, are deployed with multi-sig governance, and are monitored with on-chain analytics dashboards for the long term.
Common questions
Blockchaindevelopmentquestionseveryenterpriseasks
We develop on Ethereum, Polygon, BNB Chain, Avalanche, Solana, Hyperledger Fabric, Hyperledger Besu, and other EVM-compatible chains. We help you choose the right chain based on your use case, transaction volume, privacy requirements, and regulatory environment.
Public blockchains (Ethereum, Polygon) are permissionless — anyone can participate, and all transactions are visible. Private blockchains (Hyperledger Fabric, Besu) are permissioned — only invited participants join, and transaction visibility can be restricted. Enterprise use cases often prefer private chains for compliance and confidentiality reasons.
A focused blockchain PoC takes 4–6 weeks. An MVP with smart contracts, backend, and basic frontend typically takes 10–16 weeks. Full enterprise blockchain networks with multi-org governance can take 4–9 months depending on complexity.
Yes. We conduct internal security reviews for all smart contracts we develop. For contracts managing significant value (>$100K), we strongly recommend and coordinate external audits from firms like Certik, Trail of Bits, or Consensys Diligence.
Absolutely. We build REST API layers, GraphQL indexers (The Graph), and event-driven integration services that make blockchain data accessible to existing ERPs, CRMs, and supply chain platforms — without requiring those systems to know anything about blockchain.
