Smart contract engineering
Solidity systems designed for money that cannot be rolled back — vaults, escrow, royalty splits, on-chain settlement and upgrade paths that survive an audit.

- Upgradeable proxies
- Gas-profiled

What we build
Four disciplines, one delivery team.
Most web3 projects fail in the seams — between the contract and the product, between the product and the business. We own the whole seam.
NFT & tokenization platforms
End-to-end tokenization of real assets and collectibles: minting pipelines, metadata infrastructure, marketplaces, custody and compliant secondary transfer rules.
- ERC-721 / ERC-1155
- Marketplaces
- Metadata & media
Custom software & web apps
The other 70% of every web3 product: dashboards, admin consoles, KYC flows, ledgers, reporting and the APIs that hold a chain and a business system together.
- TypeScript / React
- APIs & indexers
- Legacy integration
Security & audit readiness
Threat modelling, invariant testing and internal review before you pay for an external audit — so the audit confirms your design instead of rewriting it.
- Invariant tests
- Threat models
- Audit liaison
Where we go deep
Three industries. Not everything.
Domain knowledge is the difference between a contract that compiles and one that holds up in the real world.
Financial
Settlement rails, tokenized funds, on-chain treasury and payment flows built to sit beside regulated infrastructure and existing reporting.
- Settlement
- Tokenized funds
- Treasury
Real estate
Fractional ownership, title and deed representation, rent distribution and investor portals — the paperwork of property, expressed as contracts.
- Fractional ownership
- Rent distribution
- Investor portals
Collectibles
Provenance, authentication and redeemable physical-to-digital links, plus the marketplaces and royalty logic that make a collection tradeable.
- Provenance
- Redemption
- Royalties
How we work
From first call to mainnet.
- 01
Architecture call
A working session with the engineers who will build it. We map the asset, the actors and the failure modes, then tell you plainly if the chain belongs in the design at all.
- 02
Fixed scope & proposal
A written technical scope with milestones, deliverables and a fixed project price in the $50k–$200k range. No hourly drift, no surprise change orders.
- 03
Build in the open
Two-week increments in your repository, on your infrastructure. Contracts written test-first with invariants, deployed to testnet you can click through from week two.
- 04
Audit, launch, hand over
We prepare the audit package, support the external review, ship to mainnet and hand you documented code your own team can operate.

What clients saySample placeholders
“They pushed back on half our original spec, and they were right. What shipped was smaller, cheaper to run and passed audit with two low-severity notes.”
“The contracts were the easy part. What we actually needed was the investor portal and the reconciliation ledger behind it — that's what they built.”
“Fixed price, fixed scope, testnet in week two. We knew exactly what we were getting before we signed anything.”
Engagements
Project-based pricing, agreed up front.
Most engagements land between $50,000 and $200,000. You approve a fixed scope and a fixed price before a line of code is written.

FAQ
Questions we get on the first call.
Still unsure whether your project is a fit? Ask us directly — we'll tell you honestly if it isn't.
Talk to an engineerEvery engagement is project-based and fixed, typically between $50,000 and $200,000 depending on scope. You get a written scope with milestones and a single price before work starts — no hourly billing, no open-ended retainers.
No. Chain selection is an outcome of the architecture call, not an input to it. We weigh settlement guarantees, fees, custody options, tooling maturity and where your users already are — and we will tell you if your product does not need a chain at all.
A small senior squad based in-house — the same engineers who join your architecture call. We do not subcontract delivery, and you always have direct access to the people writing your contracts.
We prepare for it and support it. Internally we work test-first with invariant and fuzz testing, threat models and peer review, then package everything for an independent external auditor and remediate findings with you. Independence matters, so we do not audit our own code.
You do — outright. Work happens in your repositories, on your infrastructure and under your accounts from day one, and we hand over documentation your own engineers can pick up.
Architecture calls are usually available within a week. New builds typically begin two to four weeks out, depending on squad availability.
