Chapter 1: The Rise of Crypto Treasury Vehicles

Public - market treasury strategies are reshaping how crypto gets accumulated 5

Over the last 5 years, since MSTR started buying BTC… ● BTC is up ~ 1 , 000 % ● MSTR stock is up over 3 , 000 % over the same period … ● 3.0x outperformance vs. BTC itself. MSTR showed that holding crypto on balance sheet drives outsized equity returns 6 Sources: CoinMarketCap, IBKR. Figures as of 05/12/25.

DFDV is the upgraded model – built to maximize SOL accumulation and compound SOL per share 7 Source: Internal ﬁgures. SOL HODLings inclusive of staking rewards. mNAV assumes $27.25 share price (the last reported price on NASDAQ as of 07/11/25), 18.7M total shares outstanding as of 07/09/25, and SOL/USD of $162.88. Volatility is 30D Realized. SOL per Share: SOL NAV ($): SOL HODLings : 0.0457 $140M 857,749 Volatility: mNAV: Capital Raised: 228% 3.7x $200M

Chapter 2: Legacy Structures Can’t Accumulate Crypto Fast Enough. We Can.

Exchanges Suffer From: High Fees Trading and custody fees for retail buyers often exceed 1% per transaction Limited Staking Individuals / Institutional investors often cannot stake Lack of Technology Individuals & Institutions are unable to operate validators to earn additional SOL Lack of Yield Centralized Exchanges (“CEXs”) take large validator fees and don’t enhance yield Risky Leverage High chance of margin call on CEX leverage Tax Ineﬃciency Individuals owe taxes on Staking Rewards (e.g. 1099 - MISC Coinbase) Exchanges enable trading, not accumulation. They add fees, risk, and no compounding beneﬁt.

ETFs are merely passive, fee - based wrappers that don’t compound SOL/share or offer yield Capital Deployment SOL Holdings Staking Volatility Capture Fees Operational Control Future SOL ETFs DFDV Only track SOL price with no capital compounding effect Subject to outﬂows No Staking At Launch No enhanced volatility All ETFs charge fees, eroding returns None Convertibles and PIPEs enhance returns Permanent SOL Accumulation Validator Business Enables Yield Expected higher vol than SOL, enabling options, leverage, etc. No management fees Optimize capital structure to acquire SOL opportunistically Based on the Company’s own view of the relative positioning of the various categories shown. DFDV is not an exchange traded product (“ETP”) or an exchange - traded fund (“ETF”) registered under the Investment Company Act of 1940, as amended, is not subject to the same rules and regulations as an ETP or an ETF and does not operate as an ETP or ETF. See Appendix for additional information

DeFi Development Corp. (NASDAQ: DFDV) Crypto Born. TradFi Fueled. Built to Stack Solana.

Additional Information 30 DeFi Development Corp. is not an exchange traded product (“ETP”) or an exchange - traded fund (“ETF”) registered under the Investment Company Act of 1940, as amended, is not subject to the same rules and regulations as an ETP or an ETF, and does not operate as an ETP or ETF. In particular, unlike spot Solana ETPs, we (i) do not seek for shares of our common stock to track the value of the underlying Solana we hold before payment of expenses and liabilities, (ii) do not beneﬁt from various exemptions and relief under the Securities Exchange Act of 1934, as amended, including Regulation M, and other securities laws, which enable spot Solana ETPs to continuously align the value of their shares to the price of the underlying Solana they hold through share creation and redemption, (iii) are a Delaware corporation rather than a statutory trust, and do not operate pursuant to a trust agreement that would require us to pursue one or more stated investment objectives, (iv) are subject to federal income tax at the entity level and the other risk factors applicable to an operating business, such as ours, and (v) are not required to provide daily transparency as to our Solana holdings or our daily NAV. On July 1, 2025, we entered into a prepaid forward stock purchase transaction in connection with our issuance of 5.50% Senior Convertible Notes due 2030 (“Convertible Notes”). Given the prepaid forward represents the cash amount reserved for future share settlement, NAV as presented assumes that the approximately $75.6 million paid to the forward counterparty will be treated as an asset, offsetting a portion of the associated debt from the Convertible Notes. A determination of the accounting treatment relating to the forward stock purchase transaction for purposes of GAAP is incomplete and remains subject to review, and the ﬁnal accounting treatment may cause this presentation to differ materially.
