++ What works

  • Named Swiss entity with a published registration number (CHE-196.335.293) and address
  • Operating since 2018 on 30+ PoS networks with $2.2B+ staked and institutional clients
  • Transparent 5% OPUS Pool ETH liquid-staking fee
  • Non-custodial by contract; users keep keys and can unstake at any time
  • Acquired by a regulated asset manager (Bitwise), adding compliance infrastructure
  • Open-source tooling and a public research desk

-- What to watch

  • Enterprise/public-node staking commission is not published (custom/contact sales)
  • Only the 5% OPUS figure is public; no per-network commission table found
  • No published slashing insurance or third-party uptime/performance audit
  • Binding arbitration, class-action waiver and a $10,000 liability cap
  • Broad discretion to suspend or terminate the offering (30 days' notice)

Pricing reality check

Documented price$0 % fee on staking rewards (OPUS Pool ETH liquid staking) · $5 % fee on staking rewards (OPUS Pool ETH)
NotesThe only concrete public fee found is the OPUS Pool ETH liquid-staking fee of 5% of staking rewards, observed on the Ethereum page on 2026-09-24. Enterprise/public-node delegation is priced as a 'flat Service Fee as a percentage of the Rewards earned', with the rate only 'posted on the Site' per the Terms - no per-network commission table was present on the fetched pages, so enterprise pricing is effectively custom/contact-sales.

// How to get started with Chorus One

Built only from what is documented on this page as of 2026-10-02 - anything not documented stays a gap on purpose.

  1. Open the provider site

    Everything happens on chorus.one - we count the click, nothing else changes for you.

  2. Expect a KYC step

    Documented level: required - The Terms impose AML obligations: users must provide identity and beneficial-owner documentation on request. Register before you pay.

  3. Pick the smallest unit that still works

    Price from $0/% fee on staking re - start with the minimum, not with the plan the checkout page pushes.

  4. Pay

    Accepted: ETH, SOL, ATOM, AVAX, NEAR, TON, APT, SUI, POL, DYDX, OSMO. Check the network and the deposit address inside your account, never from an email.

  5. Read the term before you sign

    maintenance · refund: Not published; Services are 'as is' and no refund terms were found. A term you did not read is money you cannot get back.

  6. Verify the output, not the dashboard

    Proof is documented as partial - Validators are publicly observable on-chain and Chorus One publishes research and open-source tooling (Chorus One SDK, Hyperliquid offline signer). Compare the first payout with the pool or wallet before scaling up.

Then run the math: mining calculator · contract vs. HODL · all staking providers.

What "legit" does not mean

A real, operating provider can still lose you money: with a contract you own no hardware, revenue follows coin price and difficulty, and most published contracts are priced so the seller comes out ahead. "Legit" means the operator exists and pays what its terms promise - not that the deal is profitable. 12 dated sources back this page; they are listed under sources.

Chorus One ETH staking/unstaking not working through Ledger - 'Not enough ETH for gas' error

User reports Chorus One ETH staking/unstaking failing through Ledger with a 'Not enough ETH for gas' error (body later deleted). A UX/self-custody caution rather than evidence of fund loss. Reddit 403 to this host; retrieved via pullpush.io.

// AI fact summary - everything we know, compressed

Generated by Qwen3 on 2026-09-28 from our fact database plus the 12 linked sources above. It summarizes - it does not add facts. Check anything that matters against the linked sources.

Bottom line: Chorus One is an active, institutional staking provider operating since 2018, now under Bitwise Onchain Solutions following a 2026 acquisition. It offers non-custodial staking across 30+ Proof-of-Stake networks with a clear 5% fee on staking rewards for its OPUS Pool ETH liquid staking product. Enterprise and public delegation fees are not publicly listed, making pricing opaque outside of OPUS.

The coverage truth: It supports staking on Ethereum, Solana, Cosmos, Avalanche, NEAR, TON, Aptos, Sui, Polygon, DYDX, Osmosis and over 20 other PoS chains. Expected reward rates are shown per network but actual returns depend on validator performance, uptime, and slashing risks - no uptime SLA or independent audit data is published.

Setup reality: Users stake directly through the Chorus One website, with self-custody maintained via non-custodial architecture. No apps or Smart DNS; setup involves wallet integration and on-chain transactions. KYC is required, including identity verification and sanctions screening, particularly for institutional clients.

What reviewers say vs what users say: Operator sources highlight long-standing operation, enterprise focus, and low 5% OPUS fees. A 2026 Reddit thread reports UX issues with Ledger-based staking/unstaking due to gas errors - indicating a self-custody friction point, not fund loss - while no major slashing or fraud incidents are documented.

Who runs it: Chorus One AG, a Swiss entity (CHE-196.335.293), now does business as Bitwise Onchain Solutions, a wholly-owned subsidiary of Attestant. The brand operates alongside OPUS, osETH, and Chorus Ventures, with the core team integrated into Bitwise after the 2026 acquisition.
