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.
Fyn (formerly BearTax)
Fyn, which previously operated under the name BearTax, delivers a structured platform designed to resolve complex cryptocurrency tax reporting and Web3 accounting challenges. The software emphasizes high volume transaction ingestion, connecting directly to exchanges, custodial accounts, and self custody blockchain addresses. By automating the normalization of trading, staking, mining, and transfer activity, Fyn simplifies the creation of tax forms such as IRS Form 8949. While the software provides clear reporting workflows and custom ledger integration for corporate accounting teams, individual users with occasional trading activity might find the tiered transaction limits restrictive. Fyn serves as a reliable calculation engine for users seeking transparent audit trails, provided they are prepared to review and classify unusual onchain transfers manually.
