The Ripple Impact: Why Solana Opens the Door
Solana’s ETF breakthrough isn’t just a win for its ecosystem — it units a starting step for different altcoins. After Bitcoin and Ethereum ETFs had been permitted primarily based on their commodity-like standing and deep liquidity, Solana turned the primary altcoin past the “Huge Two” to satisfy 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

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 (through Hydra), and interoperability might function a basis for ETF viability — notably as broader altcoin rules mature.


Avalanche (AVAX): The Enterprise-Pleasant Contender
Last within the checklist, Avalanche stands out for its modular design and enterprise enchantment. With its distinctive subnet structure, AVAX allows establishments to create customized, permissioned chains — a key differentiator in discussions round compliance-ready blockchain infrastructure.

What the SEC Seems to be For
The SEC’s strategy 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
At the moment, 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 might recalibrate the SEC’s benchmarks, notably if it contains staking, on-chain rewards, or DeFi interactions.

These might supply publicity to a basket of digital property, weighted by market cap or ecosystem power.

XRP additionally advantages from deep liquidity, constant trade assist, and a well-established use case in cross-border funds.
Avalanche (AVAX) is one other sturdy 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.
