IV. INFORMATION ON RISKS

1. Offer-Related Risks

This whitepaper is submitted by OKX Europe Limited solely for the purpose of the assets admission to trading. No public offer of ETHFI tokens is being made by the issuer or OKX Europe Limited.

Risks associated with the admission to trading include:

• Service-related Interruption: Holders may be unable to access the utility due to technical, operation, or regulatory disruptions.

• Jurisdictional limitations: ETHFI services or token utility may not be available in all jurisdictions, potentially restricting access.

• Platform Reliance: Access depends on third-party infrastructure (wallets, platforms) and service interruptions or failures may affect token utility.

• Limited Liability: OKX Europe Limited assumes no responsibility for the issuers project continuation, and token ownership does not confer contractual rights or guarantees.

• Unexpected Risks: Beyond the risks outlined in this whitepaper, there may be additional risks that are currently unforeseen. It is imperative to note that certain risks may emerge from unforeseen events, changes, or interactions among factors that are difficult to predict. These unexpected risks may significantly and negatively impact the crypto-asset, the project, or the parties involved.

2. Issuer-Related Risks

• Operational Risks: There is a risk that the issuer may face financial or operational difficulties, including insolvency, which could impact the continued development or availability of the services associated with the ETHFI token.

• Counterparty Risks: Counterparty risks may arise where the issuer relies on third-party service providers or technology partners.

• Reputational Risks: Adverse media and/or damage or loss of key personnel could negatively affect the ecosystem that the ETHFI token lives on.

• Competition Risk: The issuer may face increased competition or changes in market conditions that affect its ability to carry out its objectives.

• Regulatory Risks: The issuer may be subject to investigations, enforcement actions, or change in regulation that affect the tokens legal status in certain jurisdictions.

• Disclosure Risks: The issuer may not be required to provide financial statements, limiting ETHFI token holders visibility into the financial health status of the issuer/project.

• Issuer Risks: The information provided is based solely on publicly available sources and does not constitute any form of guarantee or warranty as to its accuracy or completeness.

3. Crypto-Assets-Related Risks

• Market Volatility: The ETHFI token may be subject to significant volatility and could lose value rapidly, either due to market conditions or otherwise (issuer-related/technology/project implementation risks).

• Utility Risk: The ETHFI tokens utility depends on access to certain services, and any modification or discontinuation of those services could reduce the associated utility of the token.

• Smart Contract Risk: The ETHFI token may operate through smart contracts that may contain vulnerabilities, even if audited, and upgrades to the protocol or governance changes may affect functionality.

• Liquidity Risk: Periods of low/limited liquidity may occur, particularly if the demand for the token or its use case decreases, which could have adverse effects on the ETHFI tokens price and future use cases.

• Token Unlock Risk: Scheduled vesting cliffs and token unlocks may significantly increase circulating supply, potentially causing volatility and/or downward price pressure.

4. Project Implementation-Related Risks

• Scalability Issues: There is a risk that the project may not be implemented or scaled as intended. Technical limitations or infrastructure bottlenecks could hinder the expected scalability of the project, especially if user demand exceeds network or protocol capacity.

• Governance Risk: The project may be subject to governance processes that involve on-chain voting or community proposals. Misaligned incentives, low participation, or malicious actors may affect the outcome of governance decisions and disrupt the project's roadmap.

• Centralisation Risk: Similar to governance risks outlined above, centralisation within the governance process, or validator centralisation could lead to a lack of decentralization within the network, which carries future risks in terms of trust within the project, and also in regards to future roadmaps where plans may not reflect the interests of the broader user base.

5. Technology-Related Risks

• Blockchain Performance Risk: The Ethereum blockchain, on which the token is primarily issued, may experience downtime or congestion, which could delay or prevent token transfer or utility usage.

• Consensus Failure Risk: A failure in the blockchains consensus mechanism could result in halted transactions, unexpected behavior, or loss in network integrity.

• Smart Contract Vulnerabilities: Although the token uses audited or standard smart contract makeups (ERC-20 standard), undetected bugs, exploits, or implementation errors could compromise functionality or security.

• Upgradeability Risk: if the token or related contracts are upgradeable and have designated "owner" addresses, this introduces a central point of failure, and could be misused by malicious actors.

• Third-party Infrastructure Dependency: Interaction with the token or project may rely on external infrastructure (APIs, wallet services, off-chain governance voting). Outages or attacks may interrupt access to token-related services.

• Interoperability Risk: If the token interacts with other chains, bridges, or oracles, failures or exploits in those systems could affect the tokens operations.

• Protocol-level Risk: Upgrades or forks of the protocol itself may affect the token, which could lead to compatibility issues and/or unexpected token behaviour.

• Emerging Technology Risk: Advances in computing or undiscovered vulnerabilities in cryptographic algorithms may pose long-term security risks to the blockchain or associated smart contracts.

• Sequencing Risk: The token may rely on a centralised sequencer(s) to process transactions to the native L1 network. If the sequencer(s) experience downtime, censorship, or misuse, transaction ordering and availability may be adversely affected.

6. Mitigation Measures

• Blockchain Performance Risk: The Ethereum blockchain has adopted a Proof-of-Stake consensus mechanism to improve network scalability and reduce latency. Ongoing upgrades to the network are designed to enhance throughput, and gas fees help prioritise transactions under load.

• Consensus Failure Risk: Ethereum Proof-of-Stake consensus mechanism includes validator incentives, slashing penalties for malicious actors, and finality checkpoints to ensure integrity. The validator set is large and globally distributed which reinforces decentralization of the network.

• Smart Contract Vulnerabilities: Smart contracts on Ethereum are immutable by design, unless explicitly designed to be upgradeable. The ecosystem encourages open source code, independent audits, and community input. Standardised libraries such as OpenZeppelin reduce coding errors by reusing tested components.

• Upgradeability Risk: Ethereum does not enforce upgrade functionalities within smart contracts, but supports their technical implementation. Risks related to upgradeable contracts can be mitigated through standard practices such as time delay triggers or multi-sig wallets.

• Third-party Infrastructure Dependency: The Ethereum blockchain & ecosystem supports decentralized indexing and querying via different protocols to reduce reliance on centralized third party data services.

• Interoperability Risk: Mitigations for cross-chain bridging include usage of audited bridges and token locking mechanisms.

• Protocol-level Risk: Ethereum maintains a public roadmap and follows a structured governance process. Core updates to the network undergo extensive testing and community reviews.

• Emerging Technology Risk: Ethereum developers monitor potential emerging technology threats, and are actively researching and developing quantum-resistant solutions. The network's modular design may allow for future cryptographic upgrades if required.

G. Information about the Rights and Obligations Attached to the Crypto-Asset

• G.1 Purchaser Rights and Obligations: There are no obligations attached for or of the purchaser. Purchasers of the ETHFI token obtain on-chain governance rights that enable them to participate in the decision-making process of the ether.fi DAO. These rights include voting on protocol upgrades, economic parameters, node operator whitelisting, and the strategic allocation of treasury resources. Holders also have the right to stake their ETHFI tokens in the protocol's dApp to earn ecosystem rewards in the form of points. Ownership of the token does not grant any claim to profits, dividends, or assets of the issuer.

• G.2 Exercise of Rights and Obligations: As the token does not grant obligations, there is no conceivable way to exercise such obligations. Purchasers can exercise their governance rights by participating in the DAO's voting process, which is conducted via Snapshot. The right to earn staking rewards is exercised by staking ETHFI tokens in the official ether.fi dApp. These rights are programmatic and do not confer any legal ownership or contractual rights against the project or its contributors.

• G.3 Conditions for Modifications of Rights and Obligations: As the token does not grant obligations, there are no conditions under which the obligations may be modified. The rights associated with the ETHFI token, particularly governance rights, are defined by the protocol's governance framework. This framework and the rights attached to the token may be modified in the future through the DAO governance process itself, subject to a successful vote by token holders.

• G.4 Future Public Offers, if applicable: N/A

• G.5 Issuer Retained Crypto-Assets, if applicable: The Ether.fi SEZC, as the supporting entity, does not have a specific "issuer" allocation. However, allocations are made to Core Contributors (21.47%) and the project's Treasury (21.63%). The Core Contributors allocation is subject to a 3-year vesting schedule with a 1-year cliff. The Treasury is managed by the DAO and is intended to fund ecosystem development and adoption.

• G.6 Utility Token Classification: TRUE

• G.7 Key Features of Goods/Services of Utility Tokens: The ETHFI token provides access to governance participation in the ether.fi protocol. This allows holders to vote on the protocol's future direction, including technical upgrades, fee parameters, and treasury management.

H. Information about the Underlying Technology

• H.1 Distributed Ledger Technology, if applicable: See F.14

• H.2 Protocols and Technical Standards: The ETHFI token is implemented using the ERC‑20 token standard on the Ethereum blockchain. ERC‑20 is the widely adopted standard for fungible tokens on Ethereum, defining a common interface for token issuance, transfers, and third-party integrations. ERC‑20 tokens are deployed via smart contracts that control total supply, balances, and permissions, and are compatible with Ethereum wallets, DeFi applications, and decentralized exchanges. The standard supports functions such as transfer, approve, mint, and burn, enabling programmable token logic through Ethereum's account-based architecture. When deployed on Layer-2 (L2) networks (e.g. Arbitrum in the case of ETHFI), the token continues to follow the ERC-20 standard but may require L2-specific infrastructure for full interoperability with wallets and applications.

• H.3 Technology Used, if relevant: The ETHFI token is deployed on the Ethereum blockchain using the ERC‑20 token standard. Ethereum is a general-purpose Layer 1 blockchain that supports smart contract execution via the Ethereum Virtual Machine (EVM). The token contract is written in Solidity and interacts with the Ethereum network using RPC-compatible clients. The Ethereum ecosystem enables composability with DeFi, NFT, and DAO infrastructure, and supports programmable token functionality within a Turing-complete environment. L2 deployments for this token rely on off-chain sequencing or batching mechanisms, and user interactions may involve rollup-specific bridges or smart contracts.

• H.4 Consensus Mechanism, if applicable: Ethereum uses a Proof-of-Stake (PoS) consensus mechanism. Validators are selected to propose and attest to new blocks based on the amount of ETH they have staked. Blocks are finalized through a checkpoint-based finality system, with strong economic incentives to penalize dishonest behavior. This mechanism supports decentralization, finality, and high security. This consensus model ensures the integrity of the blockchain, including the execution and recording of all associated transactions for the ETHFI token. While L2 networks which this token is deployed on ultimately settle to Ethereum's Proof-of-Stake consensus, their interim execution may depend on centralized sequencers or fraud/validity proofs.

• H.5 Incentive Mechanisms and Applicable Fees: Ethereum validators earn rewards in the native token (ETH) for producing and attesting to blocks. Gas fees are paid in ETH and are required to execute transactions or smart contract calls, including ETHFI token transfers. Under EIP-1559, a portion of the base fee is burned while the remainder is distributed to validators. Fees vary depending on network congestion and computational complexity of the transaction. L2 networks typically reduce gas fees for users, though additional fees may apply when bridging assets between Ethereum and the L2 network that this token is deployed on.

• H.6 Use of Distributed Ledger Technology: FALSE

• H.7 DLT Functionality Description: N/A

• H.8 Audit of the Technology Used: TRUE

• H.9 Audit Outcome, if applicable: The ether.fi protocol has undergone multiple distinct smart contract audits covering its product suite. Audits have been conducted by firms including OpenZeppelin and Cantina. Full audit reports are available in the project's public GitHub repository; https://github.com/etherfi-protocol/smart-contracts/tree/master/audits.

I. Information on the Principal Adverse Impacts on the Climate and Other Environmental-Related Adverse Impacts of the Consensus Mechanism Used to Issue the Crypto-Asset.

• I.1 Name: OKX Europe Limited

• I.2 Relevant legal entity identifier: 54930069NLWEIGLHXU42

• I.3 Name of the crypto-asset: ether.fi governance token

• I.4 Consensus Mechanism: The crypto-asset's Proof-of-Stake (PoS) consensus mechanism, introduced with The Merge in 2022, replaces mining with validator staking. Validators must stake at least 32 ETH every block a validator is randomly chosen to propose the next block. Once proposed the other validators verify the blocks integrity. The network operates on a slot and epoch system, where a new block is proposed every 12 seconds, and finalization occurs after two epochs (~12.8 minutes) using Casper-FFG. The Beacon Chain coordinates validators, while the fork-choice rule (LMD-GHOST) ensures the chain follows the heaviest accumulated validator votes. Validators earn rewards for proposing and verifying blocks, but face slashing for malicious behavior or inactivity. PoS aims to improve energy efficiency, security, and scalability, with future upgrades like Proto-Danksharding enhancing transaction efficiency.

• I.5 Incentive Mechanisms and Applicable Fees: The crypto-asset's PoS system secures transactions through validator incentives and economic penalties. Validators stake at least 32 ETH and earn rewards for proposing blocks, attesting to valid ones, and participating in sync committees. Rewards are paid in newly issued ETH and transaction fees. Under EIP-1559, transaction fees consist of a base fee, which is burned to reduce supply, and an optional priority fee (tip) paid to validators. Validators face slashing if they act maliciously and incur penalties for inactivity. This system aims to increase security by aligning incentives while making the crypto-asset's fee structure more predictable and deflationary during high network activity.

• I.6 Beginning of the period to which the disclosure relates: 2024-11-04

• I.7 End of the period to which the disclosure relates: 2025-11-04

• I.8 Energy consumption: 902.16696 (kWh/a)

• I.9 Energy consumption sources and methodologies: The energy consumption of this asset is aggregated across multiple components: To determine the energy consumption of a token, the energy consumption of the network(s) ethereum is calculated first. For the energy consumption of the token, a fraction of the energy consumption of the network is attributed to the token, which is determined based on the activity of the crypto-asset within the network. When calculating the energy consumption, the Functionally Fungible Group Digital Token Identifier (FFG DTI) is used - if available - to determine all implementations of the asset in scope. The mappings are updated regularly, based on data of the Digital Token Identifier Foundation. The information regarding the hardware used and the number of participants in the network is based on assumptions that are verified with best effort using empirical data. In general, participants are assumed to be largely economically rational. As a precautionary principle, we make assumptions on the conservative side when in doubt, i.e. making higher estimates for the adverse impacts.
