What companies are indicating to use solana?

The deep research logic is organized as follows: 

Okay, let's tackle this question. The user is asking which companies are indicating to use Solana. First, I need to go through the provided references to find all mentions of companies integrating or using Solana. 

Starting with the references, I see several articles about companies like DeFi Development Corp., Upexi, SOL Strategies, and others. These companies are either tokenizing their shares on Solana or using it for their treasury strategies. For example, Upexi (UPXI) is mentioned in references 2, 14, 15, 16, 17, 18. They're tokenizing their shares and increasing their Solana holdings. Similarly, DeFi Development Corp. (DFDV) is using Solana for validator nodes and staking, as seen in references 4, 5, 7, 19, 20, 21, 22. 

Then there are financial institutions and exchanges like Kraken, Bybit, and MEXC IgniteX. Kraken is tokenizing stocks on Solana (references 7, 12, 13, 31, 34, 35, 36, 38, 41, 42, 43, 44). Bybit and MEXC IgniteX are also involved in tokenized assets on Solana. 

ETFs are another big area. REX Shares, Osprey Funds, Invesco, Galaxy Digital, and others are filing for Solana ETFs (references 1, 3, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45). These filings indicate institutional interest in Solana as an investment vehicle. 

Other companies like Robinhood (references 33, 34, 35, 36) and Kamino Finance (reference 38) are integrating Solana for tokenized stock trading and DeFi applications. There's also mention of partnerships with Kazakhstan to support blockchain education and startups (references 28, 29, 30, 31, 32). 

I need to organize these into categories: Treasury Strategies, Tokenized Assets, DeFi & NFTs, ETFs, Partnerships, and Others. Each category should list the companies involved with brief explanations. Also, the user's profile mentions interest in US Tech, AI, meme stocks, Nancy Pelosi's portfolio, and the Metaverse. While Solana itself isn't directly related to these, the companies using Solana might align with these interests. For example, tokenized stocks could be seen as a tech innovation, and some of the companies involved might be in the tech sector. 

I should also check if any of the companies mentioned are in the user's portfolio (CRM, A, BA, BDC, G). None seem to be directly, but the ETFs and tokenized assets could be relevant as alternative investments. 

Finally, the answer needs to be structured with clear headings, tables, and citations. Make sure to include all relevant companies and their specific uses of Solana. Also, highlight the significance for the user's interests, like the tech angle or potential for high-risk, high-reward investments.
