Terms of Service

01Acceptance of these terms

These Terms of Service (the “Terms”) form a binding agreement between you and Xendra Labs OÜ, a company registered in Tallinn, Estonia under registry code 16428801 (“Xendra”, “we”, “us”). They cover the Xendra mobile apps, the desktop app, the browser extension, the websites we operate and the public APIs we publish (together, the “Software”).

You accept these Terms by installing, opening or continuing to use the Software. If you do not accept them, uninstall the Software and stop using it. If you are accepting on behalf of a company, you confirm you are authorised to bind that company.

02Who may use Xendra

You may use the Software if you are at least 18 years old (or the age of legal majority where you live) and are not barred from using it under any applicable law.

You may not use the Software if you are located in, ordinarily resident in, or organised under the laws of a jurisdiction subject to comprehensive sanctions, or if you appear on a sanctions list maintained by the European Union, the United Nations Security Council, the United Kingdom or the United States Office of Foreign Assets Control.

We do not verify your identity, because we do not hold your assets and do not act as an intermediary in your transactions. That does not exempt you from the laws that apply to you.

03What the Software does and does not do

Xendra generates and stores cryptographic keys on your device, builds transactions from your instructions, signs them locally and broadcasts them to public blockchain networks. It also displays balances, prices and decoded transaction information gathered from third-party sources.

Xendra is not

• a custodian, bank, payment institution, money transmitter or e-money issuer;
• an exchange, broker, dealer or investment adviser;
• a party to any trade, swap or bridge you perform through a third-party provider quoted inside the app;
• a source of financial, tax or legal advice.

Prices, routes, gas estimates, token labels and risk warnings are informational. They come from oracles, indexers and aggregators that can be delayed, incomplete or wrong. You are responsible for verifying every transaction on the confirmation screen before you sign it.

04Your keys, your responsibility

When you create a wallet, the Software derives a BIP-39 recovery phrase and the keys for all seven supported networks from it. That phrase is the wallet. Anyone who reads it controls every asset it can reach, on every chain, forever.

You agree to

• record your recovery phrase offline and keep at least one copy in a separate physical location;
• never type, photograph, paste or store the phrase in any online service, including cloud notes, chat apps, password managers you do not control, or any website that asks for it;
• keep the device unlocked only by you, and keep its operating system current;
• verify addresses, amounts, networks and contract approvals before signing;
• maintain your own backups of any shard, passphrase or hardware signer you configure.

05Third-party networks and services

The Software talks to blockchain networks, RPC providers, price feeds, block explorers, swap aggregators, bridges, fiat on-ramps and hardware signers operated by other people. Those services have their own terms and their own failure modes.

When you accept a swap or bridge quote, you enter into a transaction with that provider or with a smart contract, not with us. We do not guarantee execution, settlement, rates, slippage, bridge finality, or that a bridged asset will remain redeemable. We receive no fee on quotes unless a fee is displayed to you on the confirmation screen before you sign.

You may replace the default RPC endpoints with your own at any time. If you do, the reliability and privacy of the connection become your responsibility.

06Acceptable use

You agree not to use the Software to commit or facilitate a crime, launder proceeds of crime, finance terrorism, evade sanctions, or violate the rights of others.

You also agree not to:

• attack, overload, probe or degrade our infrastructure or the infrastructure of our providers, except within the scope of our bug bounty;
• distribute modified builds of the Software under the Xendra name or brand marks;
• use our name, logo or wordmark to imply endorsement, other than as permitted by the brand guidelines;
• scrape or resell our APIs beyond the published rate limits;
• impersonate Xendra support anywhere, at any time.

07Fees

The wallet is free to download and free to use. Sending a transaction costs a network fee that is paid to validators or miners, never to us. On Tron, the Software may rent energy on your behalf and returns it automatically; the cost of that rental is shown before you sign.

Swaps and bridges carry a service fee charged by the provider you selected. Where Xendra receives a share of that fee, the amount and the percentage are displayed on the quote and on the confirmation screen. We do not add hidden spread to quoted rates.

We may introduce paid features in future. Existing free functionality that concerns key generation, signing, sending and recovery will remain free.

08Intellectual property and open source

Large parts of the Software are published under an open-source licence and can be read, built and audited by anyone. Those parts are governed by their own licences, which prevail over these Terms to the extent of any conflict. See Open-source licences for the full list.

The Xendra name, wordmark, logo and visual identity are ours and are not licensed by the open-source licences. Permitted uses are described in the brand guidelines.

You keep everything you create with the Software. We claim no interest in your keys, addresses, transactions, labels or contacts.

09No warranty

The Software is provided “as is” and “as available”, without warranties of any kind, whether express, implied or statutory, including merchantability, fitness for a particular purpose, title and non-infringement.

We do not warrant that the Software will be uninterrupted, timely, secure or error-free, that defects will be corrected, that estimates will be accurate, or that any blockchain network will behave as documented. Cryptographic software can contain undiscovered flaws. Public networks can fork, halt, reorganise or change their rules without notice.

10Limitation of liability

To the maximum extent permitted by law, Xendra and its directors, employees and contributors will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, data, goodwill or digital assets, arising out of or related to the Software, whether based in contract, tort, statute or otherwise, even if we were advised of the possibility.

In particular, and without limiting the above, we are not liable for losses arising from: a lost, copied or photographed recovery phrase; a compromised or malware-infected device; a transaction you signed; a phishing site or fake support account; a third-party contract, bridge, aggregator, token or RPC provider; a network fork, halt or reorganisation; or an incorrect address you entered or pasted.

Where liability cannot lawfully be excluded, our aggregate liability is limited to one hundred euros (€100) or the total fees you paid us in the twelve months before the claim, whichever is greater.

Nothing in these Terms excludes liability for fraud, for death or personal injury caused by negligence, or for anything else that cannot be excluded under mandatory law, including consumer rights you hold in your country of residence.

11Indemnity

You agree to indemnify and hold harmless Xendra against claims, damages, losses and reasonable legal costs arising from your breach of these Terms, your misuse of the Software, or your violation of any law or third-party right. This does not apply where the claim results from our own wilful misconduct.

12Changes, suspension and termination

We may update these Terms. Material changes are announced in the app and on this page at least 14 days before they take effect, and every version is archived with its date. Continuing to use the Software after the effective date means you accept the new version.

You may terminate at any time by uninstalling the Software. Termination does not affect your keys: your wallet exists on the blockchain and can be restored in any compatible wallet using your recovery phrase.

We may discontinue a feature, a supported network or the Software as a whole. If we do, we will give at least 90 days notice for anything that affects access to funds, and we will publish the derivation paths and formats needed to move your wallet elsewhere.

13Governing law and disputes

These Terms are governed by the laws of Estonia, without regard to conflict-of-law rules. If you are a consumer resident in the European Economic Area, you also keep the protection of the mandatory rules of your country of residence.

Before starting proceedings, please write to contact@xendra.xyz. Most disputes end there. If they do not, the courts of Harju County, Estonia have jurisdiction, subject to any consumer right you have to sue in your own country.
