The challenge
Where teams get stuck
The problems we're most often brought in to solve.
- 01
Economic attack vectors
Flash loans and price manipulation can drain protocols even when the code has no obvious defects.
- 02
Complex parameter calibration
Collateral ratios, rewards and fees must be set carefully to keep the protocol solvent.
- 03
Inherited composability risk
Integrations with other protocols import their vulnerabilities and failure modes.
Overview
DeFi Protocol Engineering at VulcanTech
DeFi (decentralised finance) development is the engineering of on-chain protocols for lending, staking, swaps and yield without a traditional intermediary. VulcanTech builds DeFi protocols and their interfaces, including lending markets, staking and rewards, token swaps, yield vaults and on-chain treasury tools. We favour proven designs and conservative parameters, use established oracle networks and plan staged launches with deposit caps, monitoring and independent audits before user funds are at stake.
Key deliverables
- Protocol design and risk parameters
- Audited protocol contracts
- User interface and analytics
- Monitoring and pause controls
- Staged launch plan

Our process
How we deliver
A delivery process you can see into — from first workshop to production support.
- 01
Discovery
A focused working session on your objectives, constraints and existing systems. It concludes with a scoped proposal and a clear view of value, risk and effort.
- 02
Architecture & planning
We agree the target architecture, data model and integration approach before product code is written, and secure your sign-off.
- 03
Iterative delivery
Working software reaches a staging environment on a regular cadence, giving stakeholders continuous visibility and the ability to steer priorities.
- 04
Assurance & hardening
Automated testing, accessibility and performance budgets, and a security review are completed before anything reaches production.
- 05
Launch & continuity
We manage cutover and remain engaged through an agreed support period, with a structured handover to your teams or ongoing operation by ours.
Engagement models
Work with us the way that suits you
Outcome-based delivery
A defined scope, timeline and commercial model agreed after discovery. We own delivery risk against the agreed outcomes.
Best for: Well-defined initiatives, MVPs and first releases
Dedicated product teams
A cross-functional pod — engineering, design, QA and delivery leadership — aligned to your roadmap and scaled as priorities change.
Best for: Long-term product development and evolving roadmaps
Team extension
Senior engineers embed in your organisation, work inside your processes and report to your leaders — on contracts that assign all IP to you.
Best for: Adding specialist capability without growing headcount

Why VulcanTech
A partner, not a vendor
Senior engineering, honest delivery, and work we can name.
Senior engineers own delivery
The engineers who scope your programme in discovery are the engineers who deliver it. There is no hand-off to a junior bench after contract signature.
Engagement models that fit
Outcome-based delivery, dedicated product teams, team extension or global capability centres, matched to how your organisation prefers to work.
A verifiable track record
Every customer story we publish describes real production work, naming the client wherever confidentiality allows, including public-sector platforms secured through competitive tenders.
80+ projects in 16 countries
Delivered since 2021 across the public sector, real estate, healthcare, manufacturing and consumer technology, for regulated and high-growth organisations alike.
