Blockchain development

A blockchain product needs more than a transaction button. We work on the application around the chain: wallet connection, readable balances, transaction states and the interfaces people use to complete a task.

What can we build?

  • Decentralised application interfaces and wallet connection
  • Integration with contracts and network APIs
  • Bridge, exchange and NFT application workflows
  • Maintenance, debugging and frontend redesign for existing products

Technology and stack

TypeScript, React and Next.js for the interface; Solidity where EVM contract changes are part of the scope. Network API and wallet libraries are selected for the target chain. Our portfolio includes work in the Telos ecosystem.

How does delivery work?

  1. 1.

    Map the user journey and decide whether blockchain solves a real requirement. Document network dependencies and the data the interface must read.

  2. 2.

    Build the application and integration layer. Handle wallet rejection, insufficient funds, network changes and delayed confirmations explicitly.

  3. 3.

    Test on the target network with representative transactions. Check loading states, error messages and the behaviour of external dependencies.

  4. 4.

    Prepare a release, document configuration and agree ownership of ongoing maintenance and incident response.

Portfolio example: Telos Bridge

The twelvebit portfolio includes a frontend redesign for Telos Bridge. Bridge interfaces require clear steps and transaction status across networks, making integration behaviour part of the interface work.

Can you work on an existing dapp?

Yes. An engagement can start with an existing codebase, a frontend redesign or a maintenance task. Share the network, repository access requirements and the user flow that needs attention so we can define the work.
