Web3

Web3 product design and development, built for launch day.

DeFi, tokenized assets, dApps and token launches — the web app, the mobile app and the contracts behind them, designed and built by the person you talk to.

01Who it’s for

Built with the people who answer for the launch.

Founders
You’ve closed a round and set a date — a launch or a TGE. You need the product shipped, not a team of contractors to manage.
Product leads
The roadmap is full and Web3 UX is the gap. You need a senior who works in your Figma, GitHub and Linear from the first week.
Technical leads
You want code your team can take over: a current stack, tests on every change, contracts analysed and ready for an audit.

02What gets in the way

Where products like this lose people.

01
Money asked for before trust is earned.
People are asked to hand a contract their funds. Safety has to be said before the deposit, and every failed transaction needs a way back.
02
Too many numbers, too few answers.
On-chain data never ends. A screen has to answer one question at a time — and say where each number comes from.
03
Two unfamiliar things at once.
A new kind of asset and a new way to pay for it. Both have to be shown, not explained, before anyone buys.

03What we build

What we build in Web3.

DeFi, vaults & lending
Strategy vaults, lending and staking: the yield, the lock-up and the risk said where the money moves.
- Vaults & strategies
- Lending & staking
- Portfolio
- Wallet connection

Tokenized real-world assets
Fractional ownership of property and other real assets: the asset drawn, the contract told as a story, the purchase first in the dashboard.
- Token dashboard
- Presale rounds
- Pay from an account or a wallet
- Visible security

dApps & on-chain analytics
Rankings and dashboards over on-chain data: filters beside the list, every number with its source, an honest empty state.
- Rankings & filters
- Per-chain views
- Token & community metrics

Token launches & presale sites
The page a community meets first: the offer and its proof on one screen, tokenomics, the roadmap and how to buy.

Smart contractsTested, fuzzed and statically analysed on every change. Before contracts hold real funds on mainnet, we recommend an independent audit — and prepare the code for it.

04Mobile

The mobile app, as part of the product.

iOS and Android from one React Native codebase, on the same design system and the same back end as the web app — so a release reaches every screen at once.

05How it runs

One person on every call, checks on every change.

The same six stages on every project — and the tools this kind of product is built with.
