Blockchain & DePIN engineering
We build tailored blockchain solutions and are specialists in Bitcoin, Solana, smart contracts and DePIN projects.
Blockchain development at devs group serves companies in Switzerland: the broker backend of the Bitcoin app Relai, the decentralised GNSS network of onocoy, and smart contracts on EVM-compatible chains.
Our core competencies in blockchain
Our expertise covers a broad range of blockchain protocols, so that every project gets the right technical basis:
Bitcoin protocol: the foundation for secure, transparent transfers of value.
Solana: a high-performance blockchain, ideal for fast and cost-efficient decentralised applications.
EVM-compatible chains: we know the Ethereum Virtual Machine ecosystem, which lets us build complex smart contracts and decentralised finance (DeFi) solutions.
We put that know-how to work on your specific requirements:
DePIN (decentralised physical infrastructure networks): we specialise in delivering DePIN projects. These decentralised networks let you manage and tokenise physical infrastructure such as sensors, IoT devices or server capacity effectively.
Smart contracts: we build secure, automated contracts that execute business logic directly on the blockchain, to simplify and automate processes.
Frequently asked
What is DePIN?
DePIN stands for decentralised physical infrastructure networks: physical infrastructure such as sensors, radio stations or GNSS reference stations is operated in a decentralised way and coordinated through token incentives. For onocoy we built such a network: a real-time backend in Go, smart contracts, and global scale through Kubernetes.
Do you have experience with Bitcoin applications in production?
Yes. For Relai we built a broker backend of 17 microservices in six months that handles the buying and selling of Bitcoin, with connections to exchanges, banks and a credit card gateway.
Do you build pure smart contract projects too?
Yes, provided there is a viable business model behind them. We develop and test smart contracts on EVM-compatible chains and on Solana. For purely speculative token projects with no technical foundation we decline; in the end that protects both sides.
Does my project actually need a blockchain?
Often not, and in that case we say so. A database with clean permissions beats a chain in almost every case where all parties trust each other. A blockchain earns its place where independent parties have to be coordinated without a central authority, as with onocoy’s station operators. That check is the first step of every blockchain conversation we have, and it is why our blockchain projects hold in operation what the pitch promised: Relai and onocoy have been running in production for years without incident, and both case studies are documented in full on this site.
