Decentralised app and smart contract development

Decentralised applications that run on blockchains and peer-to-peer networks instead of a single company's server.

A decentralised application keeps working when no single company is in charge of it. The rules live in smart contracts anyone can inspect, users sign with their own keys, and data sits on a network instead of one server. We build the contracts, the storage and the interfaces, and we are plain about which parts of your product belong on-chain and which do not.

What we take on

Contracts written and tested in Solidity: Smart contracts for tokens, NFTs, escrow and DAOs on Ethereum-compatible networks such as Polygon, with automated tests before anything is deployed.
Wallet sign-in and signing: Wallet connection inside web and mobile apps, so users approve each action with their own keys.
On-chain payments: Crypto payments with transaction tracking and confirmations your back office can reconcile.
Content on decentralised storage: Files and front ends stored on networks such as IPFS, addressed by their content instead of a server.
Serverless peer-to-peer apps: Messaging, file sharing and sync that run between users' devices with no central server.
Front ends for contracts: Web interfaces that read from and write to the chain, and explain each transaction in plain language before the user signs.

A good fit when

Your product needs rules that no single party, including you, can quietly change.
Users should own their assets, identity or data, and be able to prove it without asking you.
You want payments, records or files that stay available even if your own servers do not.

Questions we are asked

Which blockchains do you build on?

Ethereum-compatible networks such as Ethereum and Polygon, using Solidity. The network is chosen for the project: fees, speed and where your users already hold wallets.

Are smart contracts tested before launch?

Yes. A contract cannot be edited once deployed, so we write automated tests, run it on a test network and review the code for known weaknesses first. For contracts holding significant value we also recommend an independent audit.

Does everything have to be on the blockchain?

No, and it rarely should be. On-chain actions cost fees and are public. We keep ownership and rules on-chain and put everything else on ordinary, cheaper infrastructure.
