About

What is Chorus One?

Chorus One is a staking provider working on proof-of-stake since 2018, with enterprise staking integrations for institutions and public nodes on 30+ networks including Ethereum, Solana, Cosmos and NEAR. Its site says Chorus One is now part of Bitwise, a crypto asset manager.

How Chorus One works

Chorus One runs validators that token holders delegate to.

You keep your tokens in your own wallet, for example Keplr for the Cosmos Hub, find the Chorus One validator and delegate; rewards come from inflation and network fees, minus the validator commission shown on each network page. Unbonding follows the network's rules, such as 21 days on the Cosmos Hub. For ETH, Chorus One offers OPUS, a non-custodial product that stakes ETH, can mint osETH and restake on EigenLayer, with an SDK for platforms.

White-label nodes let an exchange or custodian run a validator under its own brand and commission while Chorus One operates it, with a 99.99% uptime SLA and a 24x7 on-call DevOps team. Keys are protected with hardware security modules and FIPS 140-2 compliant vaults plus slashing-protection logic, and the company holds ISO 27001 certification. Since Bitwise bought it in February 2026, the operating company, Chorus One AG, does business as Bitwise Onchain Solutions.

How to start with Chorus One

As an individual you need no account: buy a supported token, open its wallet, search for Chorus One in the validator list and delegate, leaving a little of the token for network fees.
Staking guides cover each network step by step.
Institutions book a meeting or use the contact form.
Chorus One points out that running your own validator usually needs a network minimum, such as 2,000 AVAX on Avalanche, which delegating to its node avoids.

Chorus One fees and limits

The staking data feed behind its network pages, dated September 30, 2026, listed 5% on Ethereum, 5% or 8% on Solana depending on the validator, 7.5% on Cosmos, 7% on Aptos, 10% on Sui and 20% on Celestia.
Chorus One says a $250,000 delegator protection pool, refreshed every quarter, covers node downtime and slashing.

Chorus One takes its fee as a commission on staking rewards, and the rate differs by network. On the Cosmos Hub, unstaking takes 21 days, during which ATOM earns no rewards, cannot be transferred and can still be slashed.

Risks to know before using Chorus One

The terms describe the service as non-custodial: Bitwise Onchain Solutions has no access to your keys and cannot take custody of your rewards, so losing your keys is your loss alone.
Network slashing penalties apply to delegators as well as the validator.
Chorus One says its infrastructure has never been slashed and keeps a $250,000 per quarter self-insurance pool for downtime and slashing.
The terms are governed by Swiss law, with binding arbitration and a small-claims exception.
