Smart contracts and tokens

I develop smart contracts and tokens based on established standards (such as ERC-20 and ERC-721), with automated tests and deployment first on test networks and then on the real one.

Wallets and web applications

I integrate connection to users' wallets, reading data from the blockchain and transactions directly from your site or app.

Honesty first

Blockchain is a tool, not a universal solution. We evaluate costs, risks and alternatives together, and proceed only if it makes sense for your project.

  • Solidity
  • Ethereum / EVM
  • ERC-20 / ERC-721
  • ethers.js
  • Hardhat
  • Wallets (MetaMask)

Case histories

VeWorld, VeChain wallet→

VeWorld is the VeChain wallet for your browser, a Chrome extension to manage crypto assets and use dApps. In an international team I set up the app structure and built the frontend in React and TypeScript: wallet creation and import, assets, transaction confirmation.

How we work

  1. 01

    Use-case check

    We work out whether blockchain really solves your problem or a simpler solution will do.

  2. 02

    Design

    I choose network, token standards and architecture, with transaction costs and security in mind.

  3. 03

    Development and testing

    Smart contracts tested on test networks before going to the real one.

  4. 04

    Integration and release

    I connect wallet, site and backend, then publish and leave you clear documentation.

Frequently asked questions

I've worked with smart contracts, tokens and wallet integration in web applications. Tell me about your project and I'll say precisely what I can do.

Mainly Ethereum-compatible (EVM) networks and their layer-2 chains, chosen by cost and target audience.

Often not. If a traditional database solves the problem I'll recommend that; blockchain makes sense when you need transparency, digital ownership or no intermediaries.

I follow established standards, write automated tests and recommend an independent review before handling significant value.
