NEW Canton development services

Open source,shared future

Velquern builds open source, protocol-agnostic infrastructure and tools to empower developers and accelerate adoption of decentralization and web3.

Build with us

Protocol

Build and maintain protocols with strategy assessment, implementation specs, cryptography, bridge integrations, and much more.

↗

Infrastructure

We power decentralization with all core services necessary for protocol development. RPC endpoints, staking, testnets, observability and more.

↗

Co-Development

Helping teams navigate complex builds from design to deployment. Co-developing, strategic guidance, refining architectures, and launching systems that scale.

/ Ecosystem partners

Ethereum Base Canton Network Polkadot IPFS Filecoin Optimism Circle The Graph Chainlink

/ Protocol

Building protocols,
powering ecosystems

We keep networks running reliably and ensure their long term resilience.

/ Argentum

Consensus client engineering

Argentum's tools and libraries enable proof-of-stake protocol development for the TypeScript ecosystem, with Rust and Zig native libraries ensuring performant and efficient execution.

Run your own full node to ensure independence while validating with a top performing client. Make the network safer without sacrificing efficiency.

/ Halden

Storage network protocol team

The Halden team is made up of storage protocol engineering experts, long-time contributors to decentralized storage, including virtual machine design, improvement proposals, and native actor development.

Halden is a Rust implementation offering fast sync with minimal hardware requirements. Validate and access chain data, run an RPC node, generate snapshots, and manage funds with a built-in wallet.

/ Vesper

Modular node framework in Go

The Vesper team is made up of experienced core developers who have contributed to sharded network evolution since its early days — node implementations, parachain infrastructure, and next-generation execution cores.

Vesper is a modular framework for building and running nodes in Go. Whether you're running a parachain or a custom network, Vesper provides the tooling to get started fast.

/ Orion Stack

Crosschain safety supervisor

As a crosschain safety service, the Orion supervisor validates messages and tracks block safety across the rollup cluster.

Acting as a trusted L1 data source, it manages rollup sync and verification, handles re-orgs, and ensures state consistency — designed to keep chain interoperability safe, smooth, and ready to scale.

/ Research & Development

From whiteboard to mainnet

Providing teams with the knowledge to implement their ideas and grow web3. We combine our skill set, knowledge and constant research to deliver new perspectives, solve complex problems and help the community drive innovation forward.

Whether it's zero-knowledge proofs or crosschain protocols, turn your blockchain vision into a prototyped, tested, and scaled reality.
