with the rigour the category demands.
Smart contracts, L2 rollups, wallet and custody integrations, tokenisation platforms, and the off-chain infrastructure that makes on-chain work usable. Built with audit-grade engineering — because on-chain mistakes are permanent.

What this means at Enigmatix
On-chain work where mistakes are permanent.
Blockchain engineering is the only category in software where 'we'll patch it in the next sprint' can cost millions. On-chain state is permanent, contracts are adversarial targets from the moment they deploy, and the blast radius of a bug extends to every downstream integration. The engineering discipline has to match.
We build smart contracts, L2 infrastructure, wallet integrations, tokenisation platforms, and the off-chain systems around them. Every contract we ship goes through internal review, external audit, and a formal release checklist. We've built for public L1s, private permissioned chains, and the hybrid architectures most enterprise programmes actually need.

What we build
Six shapes of blockchain engineering.
Most engagements are a mix of two or three of these. We scope the exact cut during discovery and the audit plan is written into the SOW.
/02
Wallet and custody integrations.
MetaMask, WalletConnect, Rainbow, Ledger, Fireblocks, BitGo. Signer abstractions so the front-end doesn't bake in assumptions about any single wallet vendor.
/03
Tokenisation and RWA platforms.
Security-token platforms, stablecoin rails, tokenised-asset custodians. With the compliance hooks — KYC, sanctions screening, jurisdictional allow-lists — regulators actually require.
/04
L2 and rollup infrastructure.
Deployment on Arbitrum, Optimism, Base, zkSync, Polygon zkEVM, plus the off-chain indexers and bridges that make L2 usable. With cost modelling across L1/L2 paths.
/05
Indexers, subgraphs, and APIs.
The boring infrastructure that makes chain data usable — The Graph subgraphs, bespoke indexers, event-driven pipelines into your analytics stack. Chain data delivered at product-app latency.
/06
Enterprise and permissioned chains.
Hyperledger Fabric, Quorum, Besu for consortia and regulated deployments. With identity, governance, and upgrade paths that survive the multi-year programmes they're built for.
Tech we work in
A pragmatic chain stack.
We pick the chain and tooling to fit the problem, the regulatory envelope, and the operating model — not the fashionable chain of the quarter.

Book a 30-min callNine times out of ten, a database is the right answer. We'll tell you so in discovery. Blockchain earns its complexity when you need trust-minimised settlement between parties who can't trust a central operator, permanent and auditable state for regulatory reasons, or programmable asset ownership. If none of those apply, we'll recommend the cheaper path.

What partners
tell us.
Most clients renew for a second engagement. The ones who don't usually hire someone from our team to run the project in-house.
We are a mental health charity and not tech minded. We needed to improve our patient registration system but wanted a company that we can relate to. Hassan took the time to meet with me and patiently went through our process to find a personalised solution for us. Hassan's team did a great job streamlining our process and connected our registration system to our patient management software. Whenever we have a glitch, they resolve this quickly. Cloudini provides a personal and efficient service and we have adopted them to be our IT provider.
Tien Kuei
CEO · Power to Live Foundation
I am writing to wholeheartedly recommend Cloudini as a premier bespoke software development agency. Our journey with them has been nothing short of exemplary, far exceeding our initial expectations. While many agencies can develop based on strict specifications, Cloudini demonstrated an incredible commitment to our project that was truly unparalleled.
Robert McPherson
Managing Director · RBM Global Ltd
Dragonfly has been working with the team at Cloudini for several years now on building out our web-based platform and APIs. One of their strengths is quickly building out a multi-disciplinary team to work on the development and delivery of features with different technical requirements. Their support has allowed us to accelerate our development work without building an internal team. They have also worked seamlessly with other third parties both during the acquisition of Dragonfly and development of our mobile app. Cloudini has been instrumental in bringing our ideas to life and providing guidance to help us make the best technical decisions. I would recommend getting in touch with them if you're looking for support.
