Identification

Chorus One is a leading global provider of staking infrastructure, delivering secure services to institutional actors since 2018.

The company supports 35 blockchains with over $3 billion in delegated assets. Chorus One has established a distinguished operational track record: zero slashing events in Ethereum since creation and sustained validator uptime exceeding 99%.

Beyond its core infrastructure operations, Chorus One is recognized as an early contributor to multiple staking-related innovations. The team has played a meaningful role in advancing liquid staking protocols, distributed validator technology (DVT), and MEV-related research and tooling.

Business Case

Chorus One serves a highly engaged institutional and sophisticated retail audience through direct partnerships, white-label staking solutions, and integrations with custodians, exchanges, and DeFi protocols. Our user base includes funds, family offices, and DAOs seeking compliant, high-yield, and liquid staking exposure.

We are launching dedicated stVault products using the for builders to enable:

  1. Delegated liquid staking with stETH minting within Reserve Ratio boundaries

  2. Delegated staking with boosted APR via automated yield-boosting strategies in partnership with market leaders.

Leveraging our existing distribution channels (API integrations, custody partners, and direct client pipelines), we target Tier 1 level commitments within 6 months post-identification.

We apply as a stVault Professional Operator with the goal of achieving Tier 1 status shortly after identification, supported by our operational excellence, institutional partnerships and long-standing alignment with Lido’s decentralization and security principles.

Chorus One is an active Lido governance participant and early contributor to stVaults design discussions.

Ops & Decentralization
Client Mix / Versions

We run a fully diversified and minority-client setup to eliminate single-point failure risk:

  • Consensus Clients: Lighthouse (primary), Teku (primary), Prysm (being adopted)

  • Execution Clients: Reth (primary), Nethermind (primary), Geth (primary)

All clients are kept on latest stable mainnet releases with staged rollouts and canary deployments. Real-time monitoring via Grafana and Prometheus.

Infrastructure Footprint

Validators run in Google Cloud across 3 different European locations. Consensus and execution clients run on bare-metal machines operated by multiple different providers, all within Europe.

  • Remote signing via Web3Signer + HashiCorp Vault

  • Web3Signer runs on the same hosts as validator clients; keys are loaded directly from Vault and never touch disk in any form

  • Multi-region redundancy with <50ms latency to beacons

  • Firewalling via iptables + VPC isolation

Geo / Jurisdiction Diversity

Nodes for Lido are currently distributed across 3 European countries (France, Germany, Netherlands) in GDPR/SOC-compliant environments. Independent legal entities and geographic distribution mitigate regulatory and outage correlation risks.

MEV Posture

We run a fully OFAC-compliant MEV strategy using only sanctioned-relay-eligible builders:

We run a fully compliant MEV strategy using only transparent, established relays:

  • Flashbots

  • bloXroute Max Profit

  • Titanrelay

  • Ultrasound Money

  • Agnostic

  • Aestus

Local block building fallback enabled. Regular compliance audits and relay performance reporting.
