Ethereum Fundamentals: Smart Contracts, Decentralization and Financial Applications

Ethereum (ETH) is a smart contract blockchain that supports decentralized applications and digital assets through programmable code. While early blockchains focused primarily on peer‑to‑peer value transfer, Ethereum broadened the use of blockchain technology by enabling developers to build financial applications, marketplaces and tokenized assets directly on‑chain. ¹

Launched in 2015, Ethereum operates as a public, decentralized network that records and validates transactions on a shared ledger. It is widely regarded as the largest and most widely adopted smart contract platform, serving as core infrastructure for many blockchain‑based financial systems.¹

How the Ethereum Network Works
Ethereum processes transactions and executes smart contracts across a distributed network of validators. Following its transition to proof-of-stake, a method where participants hold cryptocurrency as their “stake” to qualify to verify blockchain transactions, the network relies on validators who commit ETH to help secure the blockchain and reach consensus on transactions.

In this role, validators process transactions, create new blocks and help maintain network security. In return, they can earn ETH network rewards in the form of additional ETH. Reward rates vary based on the total amount of ETH participating in staking on the network, among other factors.

Smart contracts—self‑executing programs stored on the blockchain that run automatically when predefined conditions are met—enable automated financial agreements, token issuance, decentralized exchanges and other on‑chain activity without reliance on centralized intermediaries. ²

Key Features of the Ethereum Network
PROGRAMMABILITY
Smart contracts allow developers to build decentralized finance (DeFi) applications, digital marketplaces and tokenized assets.

DECENTRALIZATION
No single entity controls the network; transactions are validated by a distributed set of participants.

ECOSYSTEM DEPTH
Ethereum supports the largest on‑chain ecosystem for decentralized finance, stablecoins, Non-Fungible Tokens and tokenized assets. ³

ADAPTABILITY
Ongoing network upgrades aim to improve scalability, efficiency and long‑term sustainability. ²

Ethereum as a Digital Asset Ecosystem
Ethereum supports a wide range of blockchain‑based financial activity and applications. It is the leading platform for decentralized finance, hosting decentralized exchanges, lending protocols, derivatives applications and asset‑management tools.

Ethereum is also a primary network for stablecoins and tokenized assets, which are increasingly used for payments, settlement and digital representation of real‑world assets. ⁴ The native token, ETH, is used to pay transaction fees, secure the network through staking and support on‑chain activity.

How Do Investors Access Ethereum?
Investors seeking exposure to Ethereum typically do so through two primary approaches:

• Direct ownership of ETH, which involves managing digital wallets, private keys and custody
• Exchange‑traded products, which may offer simplified access while limiting direct interaction with the network

Each approach involves different operational, regulatory and risk considerations. ⁵

Portfolio Applications
Some investors evaluate Ethereum as:

• Exposure to the growth and adoption of blockchain-based technology infrastructure supporting Web3 and financial applications
• A component of an alternatives or opportunistic allocation
• A complement to other digital assets with different network designs and use cases

As with all digital assets, Ethereum’s role in a portfolio depends on an investor’s objectives, time horizon, risk tolerance and liquidity needs.

Key Takeaway
Ethereum is a leading smart contract blockchain that supports decentralized financial applications, tokenization and on‑chain innovation. Its programmable design and broad ecosystem help distinguish it from value‑transfer‑focused blockchains and traditional financial systems. Understanding these fundamentals can help investors more thoughtfully evaluate Ethereum’s potential role within an evolving digital asset landscape.

^{IMPORTANT INFORMATION:}

^{RISK CONSIDERATIONS
Spot Crypto ETPs are exchange-based products that track the price of an asset, i.e., bitcoin, by holding the actual asset as the underlying asset.}

^{Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network.}

^{Cryptocurrency (notably, Bitcoin) operates as a decentralized, peer-to-peer financial exchange and value storage that is used like money. It is not backed by any government. Federal, state or foreign governments may restrict the use and exchange of cryptocurrency. Cryptocurrency may experience very high volatility.}

^{Investing in digital assets involves risk, including possible loss of principal. An investment in Morgan Stanley Bitcoin Trust (MSBT), Morgan Stanley Ethereum Trust (MSSE) and/or Morgan Stanley Solana Trust (MSOL) (each, a “Trust” and collectively, the “Trusts”) are subject to a high degree of risk and heightened volatility. Each Trust is not suitable for any investor that cannot afford loss of the entire investment.}

^{Each Trust has filed a registration statement (including a prospectus) with the U.S. Securities and Exchange Commission (the “SEC”) for the offerings to which this communication relates. Before you invest, you should read the relevant prospectus and other documents such Trust has filed with the SEC for more complete information about such Trust and the related offering.}
