Our take
Chorus One
Chorus One delivers robust non-custodial proof of stake validator infrastructure tailored for institutional delegates, digital asset custodians, and protocol foundations. Founded in Switzerland, the company operates enterprise-grade validator nodes across more than forty blockchain networks, emphasizing high availability, distributed node topology, and protocol research. Because all operations remain strictly non-custodial, delegators retain full custody over their private keys and withdrawal authorizations at all times.
While Chorus One maintains a commanding presence across major ecosystems including Ethereum, Solana, Cosmos, and Polkadot, retail token holders typically encounter its infrastructure indirectly through public validator delegation or integrated custody platforms. Institutional clients seeking bespoke service level agreements, dedicated whitelabel validator clusters, or advanced MEV-boost configurations will find a sophisticated technical partner, though minimum deployment commitments and native unbonding rules apply across all integrations.
Foundry Digital
Foundry Digital functions as a foundational infrastructure provider for the institutional digital asset mining and staking ecosystem. Operating from the United States as a subsidiary of Digital Currency Group, the company focuses on serving enterprise-scale mining operations, institutional treasury managers, and corporate infrastructure developers. Its primary offering, the Foundry USA Pool, provides hashrate aggregation under a predictable Full Pay Per Share compensation structure.
Beyond mining validation, Foundry combines equipment procurement, ASIC financing, logistics management, and enterprise staking validation across multiple proof of stake networks. While the platform offers robust tooling, sub-account management, and reporting APIs, it remains strictly gated behind institutional identity verifications and enterprise contract minimums. For retail participants, smaller hobby miners, or individual stakers seeking direct self-service on-ramps, Foundry presents substantial operational barriers due to high scale requirements and bespoke commercial agreements.
