We build DApp services that can cover a wide range of use cases such DeFi, NFTs or DAO Governance on the most popular blockchains like Ethereum, leveraging the power of Web3.

Our approach

Dapps development

We develop decentralized applications (DApps) helping you and your team develop a proof of concept or integrating into existing teams.

  • JavaScript
  • Solidity
  • EVM
  • Web3
  • Ether.js
  • Ganache
  • Metamask
Integrate and deploy

We ensure the applications are built correctly and continuously deployed through high-quality development processes to ensure transparency and fast feedback. We safely deploy your application in decentralized file systems like IPFS, in modern scalable solutions like Vercel or in traditional cloud infrastructure like AWS/Google Cloud.

  • Vercel
  • IPFS
  • AWS
  • Google Cloud
Industry standards

Follow the best industry standards and highly approved coding practices. Pull request reviewing, pair programming, unit testing and different coding tools and frameworks that are widely used. We code our web applications with frameworks like React, TypeScript, Web3/Ether.js. Your users will be able to interact with the application through a different set of wallets like MetaMask, Status, Coinbase, Portis and others.

  • Web3
  • Ether.js
  • MetaMask
  • Ganache
Open source best practices

Whatever the framework or technology we use, we try to use the best practices of each opensource community, so that anyone who knows the stack can continue to evolve our fronts. Either by code format, linters, conventions, or libraries. With us there is no vendor-lock.

  • Open Source
  • Clean Code
  • Linter
  • Code Formatter
  • Static Code Analysis
  • Sentry
Devil is in the details

Changes is one of our greatest constants and so are our fronts, we try to adjust to the design and even one step further, providing added value through micro experiences such as animations or subtle interactions.

    What they say about us

    Fantastic Team. I've worked with almost all Etéreo developers in a large-scale re-launch project for one of Spain's most innovative Telcos. They had a great quality mindset, always trying to improve but also striking a good balance between perfect code and making necessary trade offs to hit critical deadlines. They were instrumental in getting the re-launch off the ground in short time and high quality. Would be very happy to work with Etéreo again.

    In 2017 we launched a new website built on Cloud architecture, with SPA technology on the front, java microservices on the backend, highly modular and scalable. This website has a continuous integration system that allows us to evolve and change as fast as the market does, offering our clients a differentiating and constantly evolving experience. In this project we work in agile and we have Etéreo's team of front and back developers.
