Blockchain development studio

Blockchain app development, from smart contract to launch

We build blockchain products for startups, for Web2 companies adding crypto features, and for agencies that need a blockchain team. You get tested contracts, a working backend and an app your users can sign in to.

Services

What we build

Each service covers the full product: the contracts, the backend that reads the chain, and the app your users see.

Smart contracts

Tokens, staking, vesting, escrow and marketplace contracts in Solidity, with full tests and deployment scripts.

Smart contract development

dApps and Web3 apps

Web apps with wallet sign-in, on-chain actions and an indexer that keeps pages fast.

dApp development

DeFi platforms

Swaps, staking, lending and yield products, with oracle checks and the risk limits an auditor expects.

DeFi development

NFT platforms

Minting, marketplaces, ticketing and loyalty programs, with royalties and metadata handled correctly.

NFT marketplace development

Wallets and crypto payments

Wallet integration, token-gated access and stablecoin checkout with webhooks and reconciliation.

Crypto wallet development

AI integration

LLM assistants, search and document processing added to an existing product, with costs and data access kept under control.

ChatGPT integration

We also build tokenization platforms, crypto exchanges, launchpads and enterprise ledgers.

Who we work with

Three kinds of team hire us

Startups launching on-chain

You have a token, a dApp or a marketplace to launch. We scope the first version, build it and get it ready for audit.

Web2 companies adding crypto

You run a working product and want wallet sign-in, stablecoin payments or NFTs. We add those parts to your stack without rebuilding it.

Agencies without a blockchain team

Your client wants a blockchain feature. We build that part and you keep the client relationship.

Process

How a project runs

Most blockchain projects that fail don't fail on code. They fail on a wrong assumption made in the first month. The first step of every project checks those assumptions.

  1. 1

    Scope

    We check whether the product needs a chain at all, then list the contracts, services and integrations. You get a written scope with open questions and a rough timeline.

  2. 2

    Build

    Contracts come with tests and deployment scripts. The backend, indexer and app are built around them, and you see working code every week.

  3. 3

    Audit

    Contracts that hold funds go to an independent audit firm. We fix the findings and the auditor checks the fixes.

  4. 4

    Launch

    We deploy to mainnet, set up monitoring and alerts, and hand over runbooks your team can follow.

Ways to work together

Pick the engagement that fits

Fixed-scope project

A defined product with a written scope, milestones and a fixed price per milestone. This suits a first version or a single feature.

Ongoing development

A developer works on your product each month, with a weekly plan and demo. This suits products that are already live.

Audit preparation and fixes

We add tests, documentation and fixes so your contracts are ready for an auditor, then fix what the audit finds.

Why us

What you can expect

A scope before a contract

You see the parts, risks and timeline in writing before you pay for development.

You own everything

The code lives in your repository, and your company owns the cloud, domain and deployment accounts.

We don't audit our own code

Contracts that hold funds go to an outside audit firm, and we fix what it finds.

Straight answers

If a shared database solves the problem without a blockchain, the scope says so.

Frequently asked questions

How much does it cost to build a blockchain application?

It depends on scope more than on the chain. A single audited token contract and a full exchange with custody and licensing differ by orders of magnitude. Send us a short description and the written scope will give you a range.

How long does a typical project take?

A token with staking usually takes a few weeks to build. A marketplace or a DeFi protocol takes several months, including the audit. The written scope gives a timeline for your product.

Do you audit your own smart contracts?

No. A developer should not audit its own code. We test every contract we write, and contracts that hold funds go to an independent audit firm before launch.

Can you work with our existing team or code?

Yes. We can take over a contract or backend another team started, or work next to your developers in your repository.

Will you sign an NDA?

Yes. We can sign an NDA before you share details of your project.

Is the information in your guides financial or legal advice?

No. The guides are general information. Token sales, exchanges, custody and anything that touches securities law need a qualified lawyer in your jurisdiction.

Tell us what you're building

Send a few sentences about the product, the chain and your timing. We reply within a few working days with the questions to settle first, a suggested scope and a rough timeline.

What "blockchain app development" means in 2026

The term covers very different kinds of work. A token launch is mostly smart contract engineering, an audit and legal review. A crypto exchange is mostly conventional backend engineering, plus custody, compliance and liquidity. An NFT ticketing system is a web or mobile product where the chain handles ownership and resale rules. An enterprise ledger is closer to systems integration than to anything in DeFi.

Regulation now shapes product design from the start. Frameworks such as the EU's MiCA and the US GENIUS Act for stablecoins mean exchanges, stablecoins and token sales need legal input before the architecture is fixed. The regional guide covers the main jurisdictions.

How to build a blockchain app

If you want to build a blockchain app, start by deciding what the chain is for. Write down which records must be shared and tamper-evident, then choose a chain and a wallet approach around that. The blockchain development services guide shows how to scope the work, and the dApp development guide covers the usual architecture. Teams building for phones should plan wallet sign-in and transaction signing early, because blockchain mobile app development changes how keys are stored and recovered. If you plan to build a DeFi app, read how DeFi protocols are built and the DeFi application development guide first.
