We build blockchain solutions that bring transparency, security, and decentralisation to your business. From smart contracts and DeFi platforms to NFT marketplaces and tokenised assets, 5labs delivers production-grade blockchain applications on Ethereum, Polygon, Solana, and private networks. Based in Edinburgh, we work with businesses across the UK to turn blockchain from a buzzword into real value.
Blockchain technology has moved well beyond cryptocurrency. Businesses in finance, supply chain, healthcare, and real estate are using it to create tamper-proof records, automate agreements through smart contracts, and build trust without intermediaries. At 5labs, we develop blockchain applications that solve genuine business problems, not just follow trends.
Our blockchain team writes smart contracts in Solidity and Rust, builds decentralised applications (dApps) with Web3 front ends, and deploys across public chains like Ethereum, Polygon, and Solana as well as private networks using Hyperledger Fabric. We also build DeFi protocols, NFT marketplaces, token launch platforms, and supply chain traceability systems.
Blockchain projects often require robust platforms to support them. Our custom software team builds the backend infrastructure. Need a user-facing web portal for your dApp? Our web development team handles that. For cloud hosting and scalability, explore our SaaS development services. Looking for intelligent automation within your blockchain workflows?

Secure, audited, and production-ready blockchain solutions
We write, test, and audit smart contracts in Solidity (Ethereum, Polygon) and Rust (Solana). Every contract goes through rigorous testing and formal verification to prevent vulnerabilities before deployment.
Full-stack decentralised applications with wallet integration, on-chain interactions, and intuitive front ends. We use ethers.js, wagmi, and Web3.js to connect your users to the blockchain without friction.
Decentralised finance protocols including lending and borrowing platforms, decentralised exchanges, yield aggregators, and staking mechanisms. Built with liquidity management and security as core priorities.
Custom NFT platforms for minting, listing, auctioning, and trading digital assets. We build marketplaces with royalty enforcement, metadata storage on IPFS, and support for ERC-721 and ERC-1155 standards.
We tokenise real-world assets including property, equity, and intellectual property. From ERC-20 token contracts to full token launch platforms with vesting schedules and governance mechanisms.
End-to-end traceability solutions that record every step of your supply chain on an immutable ledger. Built on Hyperledger or public chains, with QR code scanning, IoT integration, and real-time dashboards.
From concept to mainnet, a structured and secure approach
We evaluate whether blockchain is the right solution for your problem. Not every project benefits from decentralisation, and we will advise you honestly. If blockchain fits, we define the architecture and chain selection.
We design the system architecture, choosing between public, private, or hybrid blockchains. This includes smart contract design, data models, token economics (if applicable), and integration points with existing systems.
Our developers write clean, gas-optimised smart contracts following industry best practices. Every function is documented, and we use established patterns to minimise attack surfaces and reduce deployment costs.
Comprehensive unit tests, integration tests, and testnet deployments. We conduct internal security audits and can coordinate external audits for high-value contracts. No contract reaches mainnet without thorough verification.
We build user-friendly interfaces that connect to your smart contracts. Wallet connection, transaction signing, real-time event listening, and clear transaction feedback are all handled for a smooth user experience.
We deploy to mainnet with proper monitoring, alerting, and upgrade strategies. For upgradeable contracts, we use proxy patterns. Post-launch, we provide ongoing support and can iterate on new features.
Battle-tested blockchain tools, frameworks, and platforms
Solidity, Hardhat, Foundry, OpenZeppelin, ethers.js, wagmi, The Graph. We develop on Ethereum, Polygon, Arbitrum, and other EVM-compatible chains with well-tested tooling.
Rust, Anchor framework, Solana Web3.js, Metaplex. High-throughput applications that require fast finality and low transaction costs, ideal for DeFi and NFT use cases.
Hyperledger Fabric, Hyperledger Besu, Quorum. Permissioned blockchain networks for enterprise use cases where data privacy, access control, and regulatory compliance are essential.

Common questions about our blockchain and Web3 services
Costs depend on the project scope. A straightforward smart contract and dApp might start from £8,000 to £20,000. Full DeFi platforms or NFT marketplaces with complex tokenomics typically range from £30,000 to £100,000+. We provide a detailed quote after understanding your requirements in a free discovery call.
It depends on your priorities. Ethereum offers the largest ecosystem and strongest security guarantees. Polygon provides lower fees while staying compatible with Ethereum. Solana is suited to high-throughput applications needing fast finality. For enterprise use cases requiring privacy and permissioned access, Hyperledger Fabric is often the best choice. We help you pick the right chain during discovery.
A simple smart contract with a basic front end can be delivered in 4 to 8 weeks. More complex projects like DeFi platforms, NFT marketplaces, or enterprise blockchain solutions typically take 3 to 6 months. Security auditing adds additional time but is essential for any project handling real funds.
Yes. Every smart contract we write goes through internal code review and testing. For projects handling significant value, we coordinate with independent third-party auditing firms. We also use formal verification tools and automated analysis to catch vulnerabilities before deployment.
Yes. We build permissioned blockchain networks using Hyperledger Fabric and Hyperledger Besu. These are well suited for supply chain tracking, document verification, inter-organisational data sharing, and regulatory compliance scenarios where public blockchain is not appropriate.
Tokenisation is the process of representing real-world assets (property, shares, artwork, carbon credits) as digital tokens on a blockchain. It enables fractional ownership, 24/7 trading, transparent provenance, and programmable compliance. We handle the full process from token design to smart contract deployment and platform development.
That is one of the first questions we ask. Blockchain is valuable when you need immutability, transparency between parties who do not fully trust each other, decentralised governance, or programmable assets. If a traditional database can solve your problem, we will tell you. We build both, and we will always recommend the most practical solution.
Yes. We build APIs and middleware that connect blockchain networks with existing ERPs, CRMs, databases, and web applications. Your users do not necessarily need to interact directly with the blockchain. We can abstract the complexity so blockchain works behind the scenes within your current workflows.
