The questions RIAs should ask a crypto sub-advisor cover registration, who holds discretion, how digital assets are custodied, the investment process, reporting, fee disclosure, conflicts of interest, and compliance support. Together they let an adviser document a reasonable basis for the relationship before delegating any portion of client crypto exposure.
A crypto sub-advisor is a registered investment adviser that manages digital-asset portfolios on behalf of another RIA's clients, usually under a sub-advisory agreement. The primary adviser keeps the client relationship and fiduciary duty; the sub-advisor supplies the crypto-specific investment process, custody arrangements, and reporting. Due diligence is the adviser's documented evidence that delegation is reasonable. For background on the model, see what is crypto sub-advisory and the broader Crypto Services for RIAs Hub.

Related Questions
Does a crypto sub-advisor need to be a registered investment adviser?
Generally a firm managing client assets for compensation is acting as an investment adviser and is expected to register at the SEC or state level, depending on the facts. Confirm registration and review the Form ADV before delegating. Registration alone does not guarantee skill or good results.
Who is the qualified custodian in a crypto sub-advisory arrangement?
It depends on the arrangement. Under the SEC custody rule, client assets are generally expected to be held with a qualified custodian rather than the adviser. Ask where assets sit, review the custody architecture and SOC reports, and consult how to choose a crypto custodian and a qualified professional.
How often should an RIA review a crypto sub-advisor?
There is no single mandated interval, but advisers commonly conduct a periodic review at least annually and sooner when material changes occur. The cadence depends on the facts; document the review and the basis for it.

Compliance Note
This article is educational and does not provide legal, compliance, tax, investment, fiduciary, or custody advice. Digital assets carry market, custody, and tax risk; no sub-advisor or custody arrangement removes those risks, and crypto holdings are not FDIC- or SIPC-insured. RIAs should consult compliance counsel. Registration does not imply a certain level of skill or training.
