Solana ETF Listing Seen as a Major TradFi Victory

The listing of a Solana ETF on Wall Street is widely viewed as a major win for Solana supporters and a further signal of TradFi’s growing acceptance of crypto assets. Since launch, Solana ETFs have attracted strong institutional inflows, with four active funds drawing more than $600 million in just a few weeks. While institutional investors remain focused on price action and inflows, this enthusiasm may be overshadowing deeper technical and security risks.

Beyond Volatility: Hidden Technical Risks of Solana ETFs

While crypto volatility is an obvious concern, Solana ETFs also carry less visible technical risks tied to custody, network reliability, and indirect onchain exposure. These risks do not negate the appeal of ETFs but deserve closer scrutiny as institutional adoption accelerates.

Custodial Risk in Solana ETFs

One of the main attractions of Solana ETFs for TradFi investors is the hands-off exposure they offer. Blockchain technology remains complex for many market participants, and self-custody introduces operational and security challenges. ETFs allow investors to gain exposure to SOL without managing private keys or operational security.

Delegating custody to a third party inherently carries risk. While professional custodians deploy extensive safeguards, no system is entirely immune to exploits, internal failures, or operational errors. According to Certora DeFi security engineer Yuma Sherman, custody-related issues and potential network disruptions represent the most significant security risks facing Solana ETFs.

Sherman explains that, like any ETF, Solana ETFs rely on professional custodians to hold SOL on behalf of investors. In theory, these custodians could lose assets due to exploits, leaked private keys, or technical failures. While top-tier custodians have never experienced catastrophic losses, the theoretical risk still exists.

Bitwise’s BSOL, currently the largest Solana ETF by assets under management, stores its holdings with Coinbase Custody. Despite strong licensing and insurance protections, Coinbase has previously faced incidents involving employee misconduct and leaks of sensitive client information. These cases highlight that even regulated custodians are not entirely risk-free.

Despite these concerns, the probability of a Solana ETF collapsing due to custodian failure is extremely low. Regulated third-party custody remains one of the safest options for safeguarding hundreds of millions of dollars in assets, and the overall risk is largely theoretical rather than imminent.

Network Reliability as a Security Consideration

Another risk specific to Solana ETFs is potential network downtime. Sherman notes that if Solana’s consensus temporarily fails, token transfers could be halted. Solana experienced several outages in 2021 and 2022 lasting between four and seventeen hours, during which onchain activity was effectively frozen.

While network outages are a legitimate concern, they are not exclusive to ETF investors. Any SOL holder, whether through self-custody or ETFs, is exposed to the same underlying network reliability risks.

Smart Contract Risk and ETF Structures

At present, smart contract risk is limited for most Solana ETFs. ETF issuers generally avoid interacting with smart contracts, instead holding SOL in staking accounts. The primary onchain transactions involve staking and unstaking, which do not meaningfully expose funds to smart contract vulnerabilities.

Most Solana ETFs rely exclusively on native staking, meaning the underlying SOL is not locked into complex DeFi protocols. This simplicity significantly reduces exposure to contract-level exploits.

Some exceptions exist. REX Shares’ SSK allocates roughly three percent of its assets under management to liquid staking tokens. While this may improve redemption flexibility, it introduces limited smart contract risk to a portion of the fund’s holdings.

VanEck has also filed for a prospective jitoSOL ETF that would be fully composed of liquid staking tokens. Although jitoSOL has never been exploited and has a strong security track record, it still carries non-zero smart contract risk by definition.

Sherman emphasizes that even extensively audited programs like Solana’s spl-stake code cannot be guaranteed to be risk-free. While leading Solana LSTs have flawless security histories, it would be misleading to claim they carry zero risk.

Due to their straightforward structure, most Solana ETFs are largely insulated from smart contract threats. For TradFi investors seeking exposure to SOL, ETFs that avoid liquid staking tokens may offer a more conservative risk profile.

Second-Order Network Effects and Systemic Risk

Although ETFs are not directly exposed to DeFi exploits, large-scale hacks within the Solana ecosystem could indirectly affect SOL’s price and network stability. Major Solana DeFi protocols often hold billions in TVL, and a catastrophic exploit could trigger cascading market effects.

Traditional investors may be unfamiliar with onchain liquidation cascades and DeFi-driven contagion risks. The growth of ETFs and digital asset treasuries concentrates SOL ownership, potentially increasing validator influence and governance centralization.

Despite these concerns, ETF issuers now have significant financial exposure to Solana and are unlikely to act in ways that threaten network integrity. From a practical standpoint, concentration risk is not a pressing concern for ETF investors.

Why Solana ETFs Remain a Rational Choice

Solana ETFs represent one of the safest and most accessible avenues for institutional investors to gain meaningful exposure to SOL. While they diverge from crypto’s self-sovereign ideals, outsourcing custody to reputable institutions simplifies participation and reduces operational risk.

No investment vehicle is entirely risk-free, and Solana ETFs are no exception. However, by abstracting away technical complexity and minimizing smart contract exposure, ETFs are likely the most suitable option for the majority of TradFi investors seeking exposure to Solana.
