Custom Blockchain Development

Production-grade smart contracts, DeFi protocols, and enterprise integrations — built by engineers who have shipped on mainnet, not just testnet.

Discuss your build

Capabilities

Full-stack blockchain engineering

From protocol layer to user interface — we build the complete stack, or slot into your existing team where needed.

Smart Contract Engineering

Solidity and Rust smart contracts for EVM and non-EVM chains. Full test coverage, gas optimisation, and formal verification where required.

DeFi Protocol Development

AMMs, lending markets, yield aggregators, and staking mechanisms — built with battle-tested patterns and economic safety analysis.

NFT & Digital Asset Platforms

ERC-721/1155 contracts, metadata pipelines, royalty enforcement, and marketplace integrations for gaming, media, and IP licensing.

Enterprise Blockchain Integration

Connecting on-chain systems to existing ERP, CRM, and data infrastructure via event-driven APIs, subgraphs, and webhook bridges.

Layer-2 & Cross-chain Solutions

Rollup deployments, bridge contracts, and multi-chain state synchronisation for projects requiring scale beyond Layer-1 constraints.

Web3 Frontend & Wallet UX

React/Next.js dApps with wallet connection, transaction signing flows, and real-time on-chain data — designed for non-crypto-native users.

How we work

From spec to mainnet

Technical Discovery

We map your existing stack, define on-chain vs off-chain boundaries, and agree a technical specification before a line of code is written.

Architecture & Prototype

A working proof-of-concept validates the core mechanism and surfaces integration risks early — before full build investment.

Production Build

Iterative development with weekly demos, full test coverage, and continuous security review throughout the build cycle.

Audit & Deployment

Independent security audit, staged testnet deployment, and a monitored mainnet launch with incident response on standby.

Case studies

Shipped and in production

DeFi

Yield aggregator for an institutional asset manager

Challenge

A regulated asset manager wanted to offer clients exposure to DeFi yields without requiring them to hold or manage crypto wallets directly.

Approach

Alphaveta built a custodied yield aggregator with a permissioned smart contract layer, automated rebalancing across three protocols, and a compliance-friendly reporting API that fed directly into the client's existing portfolio management system.

Outcome

Platform launched in 14 weeks. £18M AUM onboarded in the first six months. Zero smart contract incidents. Full audit trail available for regulatory reporting.

Enterprise Integration

On-chain inventory ledger for a global logistics firm

Challenge

A logistics operator needed a shared, tamper-evident inventory record accessible to 12 supply chain partners across 4 continents — without giving any single party admin control.

Approach

We deployed a permissioned Hyperledger Besu network with role-based access controls, built a REST API abstraction layer so partners could integrate without blockchain expertise, and delivered a real-time dashboard for operations teams.

Outcome

Dispute resolution time cut from 11 days to 6 hours. Data discrepancy rate between partners dropped from 8% to under 0.2%. All 12 partners live within 10 weeks of kickoff.
