Terms of Use
This document establishes the legal framework for interacting with EtherFlyer Wallet, including usage requirements, limitations, and essential user obligations.
Last Updated: November 5, 2025
Introduction
These Terms of Use describe the conditions that apply to your access to and use of the EtherFlyer desktop wallet application (referred to in this document as “EtherFlyer”, “the wallet”, or “the software”). By installing, accessing, or using EtherFlyer in any capacity, you acknowledge that you have read, understood, and agreed to be bound by these Terms. If you do not agree with any part of these Terms, you must not download, install, or use the software.
The purpose of this document is to explain how the wallet operates, what responsibilities you have as a user, and which limitations apply to the services the software interacts with. Since EtherFlyer is a non-custodial, locally executed application, many functions depend on networks, systems, and infrastructure that the project does not control. These Terms help clarify where our obligations end and where user responsibility begins.
EtherFlyer may update or modify these Terms as the software evolves, as supported networks change, or as relevant laws require adjustments. When updates occur, the revised version becomes effective immediately upon publication on the official EtherFlyer website. Continued use of the wallet after changes means you accept the updated Terms.
By using EtherFlyer, you confirm that you are legally permitted to use cryptocurrency software in your jurisdiction, that you understand the risks associated with blockchain-based systems, and that you take full responsibility for securing your devices, passwords, and recovery materials. Nothing in these Terms should be interpreted as financial, tax, investment, or legal advice of any kind.
About EtherFlyer
EtherFlyer is a non-custodial desktop wallet designed for managing digital assets across supported blockchain networks. The software runs entirely on your local device and does not operate as an online account, hosted service, exchange, or brokerage. EtherFlyer does not store, transmit, or access private keys, seed phrases, balances, or transaction histories. All sensitive information stays within the user’s device and is never sent to external servers controlled by the project.
The application provides tools for viewing balances, generating wallet addresses, preparing and signing transactions, and interacting with decentralized exchanges and other supported integrations. Because EtherFlyer functions as an interface to public blockchain networks, the accuracy of displayed data depends on the availability and reliability of the underlying networks, RPC endpoints, and third-party data sources.
EtherFlyer is built as standalone desktop software for Windows, macOS, and Linux. Mobile applications, browser extensions, cloud accounts, and server-side wallet recovery features are not part of the product. Users maintain full control over their own wallets, including the responsibility to secure passwords, recovery phrases, and local device access.
The project may update or expand the wallet over time, including improvements to supported networks, user experience, or available integrations. These updates do not change the fundamental nature of EtherFlyer as a self-custodial tool where users retain exclusive control over their digital assets.
Eligibility
To use EtherFlyer, you must ensure that accessing cryptocurrency software is lawful and permitted in your place of residence. By downloading, installing, or using the wallet, you confirm that you meet all legal and regulatory requirements applicable to digital assets, blockchain tools, or cryptographic software. EtherFlyer does not provide jurisdiction-specific guidance, and it remains your responsibility to determine whether the use of such tools is allowed in your country or region.
You must also be of legal age to enter into binding agreements under the laws of your jurisdiction. EtherFlyer is not intended for minors, and individuals who do not meet the applicable age requirement must not use the software. The wallet is intended strictly for personal or organizational use; users may not claim affiliation with or representation of EtherFlyer unless formally authorized.
The wallet must not be used in any context that violates sanctions, export controls, or restrictions governing cryptographic technologies, digital asset management, or decentralized finance platforms. If you are subject to government-imposed limitations that restrict the use of cryptography, blockchain applications, or virtual asset services, you are not permitted to use EtherFlyer.
By continuing to use the software, you acknowledge that you meet all eligibility requirements and accept sole responsibility for maintaining compliance with any legal or regulatory obligations that apply to you.
Additional Eligibility Requirements
- Sanctions Compliance: You may not use EtherFlyer if you are located in, or ordinarily reside in, jurisdictions listed on international sanctions or embargo lists.
- Prohibited Entities: Organizations or individuals banned from using cryptographic tools, blockchain infrastructure, or digital asset platforms under local law must not access the wallet.
- Regulatory Restrictions: You are responsible for understanding whether the use of decentralized wallets, non-custodial tools, or digital asset software requires licenses or registration in your jurisdiction.
- Institutional Use: If using the software on behalf of a company or organization, you confirm that you have legal authority to bind that entity and that its use of the software is lawful.
- Ongoing Compliance: You agree to discontinue using the wallet immediately if changes in your local laws or regulatory status make its use prohibited or restricted.
Intellectual Property Rights
All materials associated with EtherFlyer, including the desktop application, user interface elements, website content, documentation, visual assets, branding, and underlying software code, are protected by applicable copyright, trademark, and intellectual property laws. These rights belong either to the EtherFlyer project or to licensors who have granted permission for their work to be used within the software.
When you download or use the wallet, you receive a limited, non-exclusive, non-transferable license to install and run the software on your personal device for lawful purposes. This license does not grant ownership of the application or any associated intellectual property, nor does it permit users to reproduce, redistribute, modify, decompile, or create derivative works based on EtherFlyer.
Users are strictly prohibited from removing or altering any copyright notices, attribution marks, or metadata included in the software or its distribution files. Any attempt to clone, rebrand, or redistribute EtherFlyer without explicit written authorization is considered a violation of these Terms.
EtherFlyer may include open-source components distributed under their respective licenses. In such cases, the rights and obligations for those components are determined by the terms of the applicable open-source licenses, which remain fully in effect. This does not alter or restrict the intellectual property rights applying to the EtherFlyer project as a whole.
Except for the limited rights expressly granted in this section, all intellectual property rights related to EtherFlyer remain fully reserved.
Non-Custodial Nature & Privacy Note
EtherFlyer is a fully non-custodial wallet, which means that all private keys, seed phrases, and encrypted wallet data are generated and stored exclusively on your local device. The project does not operate servers that hold, recover, replicate, or back up your keys, nor do we have the ability to access, view, reset, or restore them on your behalf. If you lose your recovery phrase or password, the project cannot assist in retrieving your wallet or the assets stored within it.
All signing operations, including transaction approvals and smart contract interactions, occur locally through the wallet’s embedded cryptographic modules. These operations never leave your device, and EtherFlyer does not intercept, analyze, or collect information related to your keys, balances, portfolio, or transaction history. The wallet only communicates with public blockchain networks and third-party RPC providers to fetch real-time data that is necessary for the application to function.
EtherFlyer does not collect personal information such as names, emails, identifiers, or device metadata. Any logs generated during normal use remain on your device and are never shared automatically. If support is required, you may choose to provide logs voluntarily, but this is optional and fully under your control. Logs may contain technical information about errors or network behaviour but never include private keys, seed phrases, or full transaction signing data.
Because EtherFlyer cannot access your wallet, it also cannot perform account recovery, transaction reversals, refunds, or security resets. Managing device integrity, securing passwords, and storing the recovery phrase safely are your sole responsibilities. You must ensure that your computer is free of malware, unauthorized access, or any software that may compromise sensitive information.
Transactions and Blockchain Networks
EtherFlyer operates strictly as a non-custodial interface that allows you to prepare, sign, and broadcast transactions to supported blockchain networks. The wallet does not run its own blockchain, validators, or settlement infrastructure, and therefore cannot influence how fast transactions confirm, whether they succeed, or how network fees fluctuate. Once a transaction is signed on your device and submitted to the network, it becomes irreversible and cannot be altered or cancelled by EtherFlyer.
Because all blockchain data—balances, token metadata, gas estimates, contract details—is sourced directly from public networks or third-party RPC providers, delays or inconsistencies may occasionally occur. These behaviours are natural properties of decentralized systems, and EtherFlyer cannot guarantee the accuracy or availability of external data at all times.
What EtherFlyer Cannot Control
- Transaction confirmation time
- Gas fees, priority fees, and network congestion
- Validator or miner behaviour
- Forks, reorganizations, or halted chains
- RPC outages, rate limits, or data delays
- Contract logic or actions triggered by interacting with a smart contract
- Token legitimacy, authenticity, or ongoing support by its issuer
Your Responsibilities When Transacting
- Verify the network and the receiving address before signing
- Confirm gas settings and fee levels suitable for current network load
- Review contract interactions and approvals to avoid scam contracts
- Ensure you are sending assets to compatible networks and formats
- Understand that sending to the wrong address or chain may cause permanent loss
Blockchain networks may experience unpredictable behaviour, including congestion, temporary failures, or inconsistent state updates. EtherFlyer cannot intervene in these events, recover assets, or reimburse losses resulting from on-chain activity. By using the wallet, you acknowledge that you understand the operational nature of decentralized networks and accept full responsibility for every transaction you authorize.
Fees and Payments
EtherFlyer is provided as a free, non-custodial desktop application. The project does not charge subscription fees, account fees, licensing fees, or any form of payment for downloading or using the wallet. However, when interacting with blockchain networks, users may encounter various third-party fees that EtherFlyer has no control over. These fees originate from the networks, protocols, or services you choose to interact with and are a direct result of how decentralized systems operate.
Every transaction performed through EtherFlyer — including transfers, contract interactions, token approvals, and swaps — requires a network fee (“gas fee”). These fees are fully determined by the blockchain you are using and depend on validator pricing, current congestion, and transaction complexity. EtherFlyer may display estimated ranges to help you understand expected costs, but these values are informational only and may change at the moment of confirmation.
For users performing swaps or interacting with decentralized exchanges through the wallet, additional third-party protocol fees may apply. These may include liquidity provider fees, router fees, or slippage-related changes. All such costs are imposed entirely by external protocols and not by EtherFlyer. The wallet displays available information when possible but cannot guarantee accuracy, availability, or execution outcomes.
Once a transaction is submitted and signed, it cannot be cancelled or refunded, even if the final fee or execution result differs from the displayed estimate. Users are solely responsible for reviewing all fee details before approving any on-chain action.
Fee-Related User Responsibilities
- You are responsible for paying all blockchain network fees associated with any transaction you initiate.
- You must review fee estimates before confirming a transaction.
- You acknowledge that EtherFlyer does not control, reduce, modify, or refund network or protocol fees.
- You understand that swap routing, price impact, and liquidity provider fees originate from third-party DEXs and may change at execution time.
- You accept that failed or pending transactions caused by low fees, congestion, or network instability are not the responsibility of EtherFlyer.
Supported Networks and Assets
EtherFlyer provides access to multiple blockchain networks and enables interaction with a diverse range of native coins and tokens. However, network availability, token visibility, and feature support may change over time based on ecosystem updates, technical constraints, or security considerations. By using the wallet, you acknowledge that supported networks and assets may be added, modified, or removed at any time without prior notice.
The wallet displays on-chain balances by querying publicly available blockchain data. EtherFlyer does not issue, manage, or custody any digital assets, and makes no claim of ownership or control over any listed token. Token metadata—including names, logos, and decimals—is sourced from open registries or community-driven lists and may occasionally contain inaccuracies. Users should independently verify asset details before performing any transaction.
Support for a network does not imply endorsement of that network, its operators, or any applications built on it. Similarly, displaying a token or enabling a swap route does not guarantee that the asset is safe, legitimate, compliant, or free from risk. Participation in any blockchain ecosystem carries inherent risks, including volatility, contract vulnerabilities, and liquidity issues, all of which fall outside of EtherFlyer’s control.
Because networks may undergo forks, upgrades, or instabilities, certain features—such as transaction submission, swapping, or balance indexing—may temporarily become limited or unavailable. EtherFlyer is not responsible for disruptions caused by protocol-level events, consensus failures, validator outages, or incompatible network upgrades.
User Acknowledgements
- Network support may expand or change depending on technical feasibility and safety.
- Token appearance in the interface does not constitute a recommendation or guarantee of authenticity.
- You are responsible for verifying token contracts and ensuring you are interacting with legitimate assets.
- EtherFlyer is not liable for losses caused by unsupported networks, delisted assets, or incorrect token metadata.
- The wallet does not provide investment advice, asset screening, or compliance vetting for any coin or token.
Software Updates
EtherFlyer may release updates, patches, performance improvements, and security enhancements on a regular or occasional basis. These updates are essential to maintain compatibility with supported networks, improve stability, and address newly discovered issues. By using the wallet, you acknowledge that continued access to full functionality may require installing the latest available version.
Updates may include changes such as:
- Security Patches — fixes for vulnerabilities, cryptographic updates, and improvements to internal safeguards.
- Performance Enhancements — optimizations that affect speed, resource usage, or reliability across supported platforms.
- Feature Additions or Modifications — new tools, workflow changes, interface adjustments, or updated integrations.
- Compatibility Maintenance — updates required to support network upgrades, token standard changes, or evolving API endpoints.
- Bug Fixes — resolutions for issues affecting stability, synchronization, display accuracy, or transaction handling.
EtherFlyer does not guarantee backward compatibility with outdated versions of the application. Older builds may become partially or fully incompatible with certain networks, integrations, or security standards. You are solely responsible for updating your software whenever a new version becomes available and for verifying that downloaded files originate from the official EtherFlyer website.
The EtherFlyer team is not responsible for any malfunction, loss, or reduced functionality resulting from failure to update the software, use of deprecated builds, or installation of modified or unofficial packages. By continuing to use the wallet, you acknowledge that updates are a necessary part of maintaining the safety and reliability of the application.
User Responsibilities and Prohibited Activities
By using EtherFlyer Wallet, you agree to follow all responsibilities outlined below and refrain from any activities that compromise the security, integrity, or lawful use of the software. These rules are necessary to protect both users and the broader ecosystem.
User Responsibilities
You are solely responsible for maintaining control of your wallet and ensuring that the device you use is secure and free from malware. EtherFlyer does not store, recover, or access your private keys, and therefore cannot assist in restoring accounts if security is compromised due to user negligence. Your responsibilities include:
- Secure Storage of Recovery Phrases — You must store your seed phrase and private keys in a safe, offline location. Loss, exposure, or theft of this information may lead to permanent loss of access to your assets.
- Verifying Addresses and Networks — Before sending any transaction, you must confirm that the selected network, recipient address, and token match your intended action. EtherFlyer cannot reverse transactions submitted to the blockchain.
- Maintaining a Safe Device Environment — You are responsible for ensuring that your computer is protected from malware, keyloggers, unauthorized access, and harmful software that could compromise your wallet.
- Using Only Official Builds — You should download EtherFlyer exclusively from the official website. Modified or third-party builds may contain harmful code and are used at your own risk.
Prohibited Activities
Users may not engage in any behavior that threatens EtherFlyer, its infrastructure, supported networks, or other users. The following actions are strictly prohibited:
- Reverse Engineering or Tampering — Attempting to decompile, modify, decrypt, or otherwise interfere with the wallet’s code, security protections, or internal components.
- Exploiting or Attempting to Exploit Vulnerabilities — Conducting unauthorized penetration tests, exploiting bugs, or attempting to bypass security mechanisms.
- Unauthorized Network or Service Interference — Engaging in activity that disrupts or degrades EtherFlyer services, blockchains, APIs, or third-party integrations.
- Illegal or Regulated Activities — Using the wallet to engage in activities prohibited by law, including money laundering, sanctions evasion, fraud, or any form of criminal behavior.
- Automated Abuse or Overloading — Launching scripts, bots, or automated tools that overload systems, spam network endpoints, or abuse functionality.
- Misrepresentation or Impersonation — Representing yourself as an EtherFlyer team member, affiliate, or authorized partner unless officially recognized.
Risks and Disclaimers
Using EtherFlyer Wallet involves inherent risks associated with digital assets, decentralized networks, and blockchain technology. By installing or using the wallet, you acknowledge that cryptocurrencies are highly volatile, transactions are irreversible, and the responsibility for managing keys and funds lies solely with you. EtherFlyer provides software that enables interaction with supported networks, but it does not control how those networks operate, validate transactions, or handle potential failures.
Digital assets may fluctuate in value rapidly, and market conditions can affect the availability of liquidity, confirmation times, and the cost of network fees. You may experience delays, increased fees, or failed transactions due to network congestion, node instability, or third-party service disruptions. EtherFlyer has no influence over blockchain performance and cannot guarantee transaction execution, speed, or success.
You also acknowledge the risk of losing access to your wallet if your recovery phrase is lost, stolen, or exposed. Attacks such as phishing, malware, social engineering, and fraudulent websites may target cryptocurrency users. EtherFlyer cannot protect you from threats originating outside the application environment and does not recover, store, or reset private keys, passwords, or seed phrases under any circumstances.
The software is provided on an as-is and as-available basis. While EtherFlyer aims to offer a stable and reliable application, it makes no guarantees regarding uptime, continuous availability, error-free performance, or compatibility with all tokens, networks, or third-party tools. You use the wallet at your own risk, and you are responsible for understanding the nature of the assets and networks you interact with.
Limitation of Liability
EtherFlyer Wallet is offered as-is and as-available, without guarantees of uninterrupted operation, permanent accessibility, error-free performance, or compatibility with every token, network, or third-party service. The project does not control blockchain networks, validators, mempools, smart contracts, or market conditions, and cannot influence confirmation times, fee levels, execution success, or network reliability.
EtherFlyer, its contributors, and affiliates are not liable for any form of loss or damage, whether direct or indirect. This includes loss of funds, failed or delayed transactions, corrupted data, unauthorized access resulting from malware or compromised devices, exposure of recovery phrases, market volatility, or issues caused by external APIs, integrations, or validators. Any interaction with decentralized networks carries inherent risks, and the responsibility for managing private keys, verifying transaction details, and maintaining device security rests entirely with the user.
Nothing in the software should be interpreted as financial, investment, legal, or tax advice. EtherFlyer does not guarantee outcomes or protect against user errors, network malfunctions, or third-party disruptions. Where applicable law limits liability, EtherFlyer’s total responsibility shall not exceed the amount paid for using the software, which is typically zero as the wallet is provided free of charge.
Termination
You may stop using EtherFlyer Wallet at any time by uninstalling the software and discontinuing interaction with supported networks. Because the wallet is non-custodial and operates locally on your device, deleting the application does not affect any on-chain balances or previously executed transactions. You remain fully responsible for the security and storage of your recovery phrase even after you stop using the software.
EtherFlyer may restrict, suspend, or discontinue access to future updates, services, or integrations if a user violates these Terms, attempts to compromise the security or stability of the software, abuses network resources, or engages in activity that is unlawful or harmful to other users or the broader ecosystem. These actions may be taken without prior notice if immediate intervention is necessary to protect the project or its community.
Termination of access to the software or related services does not grant any entitlement to refunds, compensation, or continued availability of features, past versions, or network connectivity. Any obligations or responsibilities that, by nature, should continue after termination—including security of private keys, compliance with applicable laws, and responsibility for previous transactions—remain in effect.
Changes to These Terms
EtherFlyer may update or revise these Terms from time to time to reflect changes in the software, supported networks, regulatory requirements, or project development. Updated versions will be published on the official website, and the effective date will be indicated at the top of the document. You are responsible for reviewing the Terms periodically to stay informed about any modifications that affect your use of the wallet.
Continued use of the software after updated Terms are posted constitutes acceptance of the revised document. If you do not agree with any modifications, you must discontinue use of EtherFlyer and uninstall the application. Because the wallet is non-custodial and operates locally on your device, choosing to stop using it does not restrict your ability to interact with blockchain networks through other tools.
Changes to the Terms do not retroactively alter prior transactions or obligations, and they do not impact the security or ownership of your digital assets. Revisions may include clarifications, technical adjustments, or policy updates necessary to maintain transparency and consistency as the project evolves.
