Get smart contracts written for you, tested before they touch money

The Build Studio writes smart contracts that do exactly what you need, tested before they touch money, at a price you name. A smart contract is a vault; write it wrong and it is a drain, and there is no undo button onchain. We write Solidity deliberately: the mechanics you specify, the failure cases you did not think to specify, and a test suite that attacks the contract before any user can. Then we walk you through what the contract can and cannot do, in plain language, before deployment. The studio's 47 live apps include dapps running contracts in production. Describe the mechanics, say the number that feels fair, and we will tell you honestly what that covers.

The 60-second version

A smart contract is a vault. Write it wrong and it is a drain.

We build it for you: solidity that does exactly what you need, tested before it touches money.

Your price, our build. ceoism.com/studio.

What you receive

  • Solidity contracts implementing exactly your mechanics
  • A test suite covering failure cases, not just happy paths
  • A plain-language walkthrough of what the contract does
  • Deployment to your chosen chain
  • Full ownership of the code and deployment keys

How it works

  1. 1

    Tell us what you need

    One email. Describe the thing in your own words, plain language is perfect, and say the number that feels fair to you.

  2. 2

    We build, you watch it become real

    We reply honestly with what your number gets, then we build. You see the live thing take shape, not a slide about it.

  3. 3

    You name the price

    The price you set is the price. When it ships, it is live on a real domain and it is yours: code, keys, everything.

The receipts

Built by the same engine.

Honest questions

Do I still need an external audit if you test thoroughly?
For contracts holding serious value, yes, and we will say so plainly rather than sell you false comfort. Our testing catches a great deal; an independent audit is a different layer, and high-stakes contracts deserve both.
Can the contract be changed after it is deployed?
Only if we design it that way. Upgradeability is a real trade-off: flexibility for you, but a trust question for users. We will lay out both paths honestly and build the one that fits your situation.
What do you need from me to start?
The mechanics in your own words: who can do what, when, and with whose money. You do not need technical language. Turning fuzzy intent into precise contract logic is exactly the job.

Name your price on this.

Tell us what you need and the number that feels fair. We answer honestly with what that number gets.

Service 023 · three takes

The films we shoot for this one

These are the scripts we actually film, published openly. Plain text is spoken out loud. Anything in the marked panels is for the camera or the screen behind us and is never read aloud. Three takes of the same service, so we can pick the one that fits where the film is going. The first is open below. Open the other two to read them.

Code that holds other people's money

Opens inside the worry this service answers, and takes its time. Made for someone who already has this problem in mind, so it fits this page and it fits an audience that already knows us.

Direction · do not readOpen on camera. Quieter than usual.

Writing something that will hold other people's money carries a particular fear with it. That fear is reasonable. I have it too.

Which is why the thing sits unwritten, or half written by someone who stopped answering.

So let us do it. Smart contracts written for you, in plain Solidity that does the one thing you need, tested before it ever touches money. And if it will hold real value, get a serious independent audit as well. That is not us, and it should not be.

Describe it badly to us. Badly is fine.

Take two · the direct cutFilm 023 · 15 to 25 seconds

You name the price on Solidity

Opens on a claim or a visible result, with the offer inside the first ten seconds. Built to be shot with a screen recording playing behind you. Made for the feed and for paid placement, where nobody was looking for us.

Read this script
Screen · do not readScreen: a Solidity file scrolling, then the test suite running green in the terminal.

You name the price on this one. On all one hundred, actually.

Screen · do not readScreen: cut to a failure-case test deliberately reverting, then a plain language summary document.

Smart contracts written for you. Solidity that does your exact mechanics, a test suite aimed at the failure cases, and a plain language walkthrough before deployment.

For serious value, pay for an independent audit as well. That is not us.

Describe the mechanics and send it.

Solidity, written for you

Names the service in the first breath instead of hiding it behind a hook, then offers to build it. It puts the barriers on the floor: you name the price, and not knowing how any of it works is our job rather than yours. It also makes the promise most people never get, that we stay with the thing until it is real. Made for someone who has been carrying this idea around for a long time and needs to hear that somebody will actually take it on.

Read this script

Smart contracts written for you. Solidity that does your mechanics, tested against the ways it could fail.

Bring us the idea, even roughly. Working out how it should function is our job, not yours.

If it will hold serious value, a proper independent audit is still a separate thing you should get.

We stay with a contract until it behaves.

There is no cost in asking, so ask.
