Blockchain development services

Blockchain development services design and build software on a blockchain: smart contracts, the websites and apps people use to interact with them, wallet and payment features, and the testing and security work around them.

Usually not. If one company controls the data and everyone trusts it, a regular database is faster, cheaper and easier to change. Blockchain fits when several parties share a record nobody should be able to edit alone, or when ownership needs to be provable by anyone.

Most projects use Ethereum or one of the lower-cost networks built on it, such as Base, Arbitrum or Polygon, because of their tooling, security and wallet support. We choose based on transaction costs, who your users are and how much the contract will hold.

We build on audited open-source libraries, write tests for every function, run automated analysis on every change and have an independent firm audit the code before mainnet. After launch, admin actions need several keyholders to approve and a waiting period before they take effect.

We prepare contracts for audit and review them internally, but for anything that will hold real value we bring in an independent audit firm. Developers should not be the only ones checking their own contract.

Only if it was designed to be. Upgradeable contracts can be changed through an approved process; others are fixed forever. We decide this with you before launch, because each choice has security trade-offs.

Each transaction pays a network fee. On Ethereum’s main network that can be significant; on lower-cost networks it is usually a small fraction of a cent to a few cents. We estimate your running costs during the proof of concept.

Yes, usually through an established payment processor that settles in dollars, so you never hold customer crypto yourself. In the US, payment stablecoins now have a federal framework under the GENIUS Act, signed in July 2025.

Not always. Newer wallet options let people sign in with an email or a passkey, and since Ethereum’s 2025 Pectra upgrade regular wallets can use smart-account features. We design for people who have never owned crypto.

It should not. Public blockchains are permanent and visible to anyone, which conflicts with privacy laws that give people the right to have their data deleted. We keep personal data off chain and store only what needs to be verifiable.

A small working version on a test network, with fake money, that shows whether the idea works, what it will cost to run and how people will use it, before you commit to a full build.

A proof of concept usually takes a few weeks. A production launch takes longer, mainly because of testing and the independent audit. Your proposal sets out the timeline by milestone.

It depends on the number of contracts, the website and app work around them and the audit, which is quoted by the audit firm. We scope it after the first call and put the cost in your proposal.

A small program stored on a blockchain that runs exactly as written when someone interacts with it, for example transferring a certificate to a new owner or releasing a payment when conditions are met. Nobody, including us, can change how it behaves unless that was designed in.

You do. The code, the deployed contracts and the admin keys belong to your business, and we document everything so another team could take it over.
