As Solana climbs the institutional ladder, the highlight turns to different altcoins that might observe its path into the ETF enviornment. XRP, Cardano (ADA), and Avalanche (AVAX) are among the many prime contenders.
The Ripple Impact: Why Solana Opens the Door
Solana’s ETF breakthrough is not only a win for its ecosystem — it units a starting step for different altcoins. After Bitcoin and Ethereum ETFs had been accepted primarily based on their commodity-like standing and deep liquidity, Solana grew to become the primary altcoin past the “Huge Two” to fulfill the dialog threshold. As of July 2025, Solana ranks #6 by market cap at over $67 billion, with each day buying and selling volumes averaging $2.5 billion throughout main exchanges.

XRP: The Darkish Horse with Authorized Readability
XRP could possibly be seen as essentially the most notable case when referring to altcoin ETFs. It’s the most legally clarified asset within the altcoin ETF dialogue. In July 2023, a U.S. federal court docket dominated that XRP gross sales on secondary markets don’t represent securities transactions, a partial victory that Ripple Labs capitalized on. Whereas the ruling didn’t totally absolve Ripple from regulatory scrutiny, it successfully eliminated one of many greatest authorized limitations to institutional merchandise primarily based on XRP.

Cardano is a robust title on this checklist. It’s seen because the “gradual and regular” contender. Its research-first philosophy, rooted in peer-reviewed educational papers and formal verification, makes it interesting to institutional buyers searching for technical rigor. With a present market cap of $25 billion, ADA ranks among the many prime 20 cryptocurrencies, and its staking ecosystem consists of over 3,200 stake swimming pools, highlighting robust decentralization.
Spurce: Coingecko
Nevertheless, Cardano’s on-chain exercise lags behind Solana and Ethereum. In response to Coingecko metrics, each day transaction quantity for ADA in June 2025 was roughly $2.6 billion, roughly to Solana’s $2.5 billion. Its DeFi TVL stays modest at simply over $400 million, limiting its case for monetary utility in comparison with faster-growing chains.
Supply: DefiLlama
But, within the eyes of conservative allocators, ADA’s long-term imaginative and prescient for governance, scalability (by way of Hydra), and interoperability may function a basis for ETF viability — notably as broader altcoin rules mature.
Avalanche (AVAX): The Enterprise-Pleasant Contender
Closing within the checklist, Avalanche stands out for its modular design and enterprise enchantment. With its distinctive subnet structure, AVAX permits establishments to create customized, permissioned chains — a key differentiator in discussions round compliance-ready blockchain infrastructure. As of July 2025, Avalanche helps over 120 subnets and has partnered with corporations like Amazon Net Providers and JPMorgan on blockchain pilots.

By way of metrics, AVAX instructions a market cap of $8.8 billion, with a DeFi TVL of $1.6 billion, rating it throughout the prime 6 within the DeFi house. Each day transaction quantity throughout Avalanche’s C-Chain averages $600 million. Its deal with real-world asset tokenization — such because the initiative with Intain and JPM — locations it in a first-rate place for institutional traction.
Supply: CoinMarketcap
Whereas AVAX doesn’t but have the authorized readability of XRP or the retail cult standing of Solana, its enterprise-first narrative may match properly into multi-asset ETF merchandise or bespoke institutional autos in regulated markets.
What the SEC Appears to be like For
The SEC’s method to ETF approvals has traditionally centered on market maturity, investor safety, and surveillance sharing agreements. For altcoins to qualify, they have to meet a number of unwritten standards:
Adequate buying and selling quantity on regulated U.S. exchangesDemonstrable decentralization and safetyReadability on token classification (i.e., not a safety)Potential for value discovery and arbitrage throughout venues
Presently, not one of the altcoins talked about have CFTC-regulated futures markets, which was a pivotal issue within the approval of Bitcoin and Ethereum ETFs. This stays the most important hurdle. Nevertheless, a profitable Solana ETF may recalibrate the SEC’s benchmarks, notably if it consists of staking, on-chain rewards, or DeFi interactions.

The Function of Multi-Asset Crypto ETFs
One other doubtless growth post-Solana is the approval of diversified crypto ETFs that embrace a number of altcoins. These might supply publicity to a basket of digital belongings, weighted by market cap or ecosystem power.

The partial court docket ruling in 2023 established that XRP, when traded on secondary markets, isn’t thought of a safety—granting it a stage of authorized readability that almost all different altcoins lack. XRP additionally advantages from deep liquidity, constant alternate help, and a well-established use case in cross-border funds.
Avalanche (AVAX) is one other robust contender, providing modular structure, excessive developer exercise, and rising adoption amongst enterprise customers. Though AVAX lacks the identical authorized readability as XRP, its real-world integrations and sturdy ecosystem make it engaging for diversified or thematic ETF merchandise.
