Terms of use
Last updated 30 July 2026
These Terms of Use (the “Terms”) govern your access to and use of the Exen web interface, its subdomains, its application programming interfaces and any related software or documentation we make available (together, the “Interface”). The Interface is published by Wraxyn (“Wraxyn”, “we”, “us”, “our”).
Read them. By accessing or using the Interface — including by requesting a quote, connecting a wallet, or signing a transaction composed through it — you agree to be bound by them in full. If you do not agree, do not use the Interface.
1. Acceptance and changes
These Terms form a binding agreement between you and Wraxyn. We may modify them at any time by publishing an updated version at this address, and any change takes effect when published. We are under no obligation to notify you of a change. Your continued use of the Interface after a change is published is your acceptance of the amended Terms. The “Last updated” date at the top of this page indicates when the current version took effect.
If you use the Interface on behalf of an entity, you represent that you have authority to bind that entity, and “you” means that entity.
2. Eligibility and restricted persons
You represent and warrant, each time you use the Interface, that you are at least 18 years old and have full legal capacity to enter into these Terms, and that you are not:
- a resident, national or agent of, or located in, any jurisdiction subject to comprehensive sanctions, or any jurisdiction in which access to or use of the Interface, or the trading of digital assets, is prohibited or would require a licence, registration or authorisation we do not hold;
- a person or entity listed on, or owned or controlled by a person or entity listed on, any sanctions or restricted-party list maintained by the United States (including OFAC’s SDN list), the United Kingdom, the European Union, the United Nations or any other applicable authority;
- acting on behalf of, or transacting for the benefit of, any such person or entity;
- using the Interface to conduct, facilitate or conceal any unlawful activity, including money laundering, terrorist financing, fraud, market manipulation, sanctions evasion or the proceeds of crime.
You are solely responsible for determining whether your use of the Interface is lawful where you are, and for complying with every law that applies to you. We may, at our sole discretion and without notice or liability, block, restrict or refuse access to the Interface from any address, wallet, jurisdiction or network — including on the basis of screening, geolocation or our own judgement, and including retroactively mid-session.
3. What the Interface is — and what it is not
The Interface is a graphical and programmatic front end to publicly available, permissionless smart contracts and to third-party liquidity venues. Its function is to read public data, compute a proposed route across venues, and present you with an unsigned transaction that you may choose to sign with your own wallet.
We are not a party to your transactions. We do not take custody or control of your assets, private keys, seed phrases or wallet at any time. We do not hold, transmit, exchange or convert funds on your behalf. We do not act as a broker, dealer, exchange, market maker, money services business, money transmitter, custodian, trustee, investment adviser, financial adviser, fiduciary or agent for you or for anyone else, and no relationship of that kind is created by these Terms or by your use of the Interface.
Transactions occur directly between you and the relevant smart contracts and counterparties on public blockchain networks. Those networks and contracts are operated by third parties or by no one at all. Once a transaction is submitted to a network it is irreversible, cannot be cancelled, recalled, amended or refunded by us, and we have no ability to reverse, freeze, recover or otherwise affect it.
4. No advice, no solicitation, no endorsement
Nothing on the Interface is, or should be construed as, financial, investment, legal, accounting or tax advice, or a recommendation, solicitation, offer or inducement to buy, sell or hold any digital asset or to enter into any transaction. Quotes, routes, price impact figures, charts, statistics, token lists, labels and any other information are provided for general information only.
The appearance of a token, protocol, venue, market maker or third-party service in the Interface is not an endorsement, verification, guarantee or assurance of its legitimacy, safety, quality, solvency, compliance or fitness for any purpose. Token metadata, symbols, names and logos are supplied by third parties and by token issuers themselves; they can be misleading, spoofed, or deliberately designed to imitate another asset. You are solely responsible for verifying the identity and contract address of any asset you trade and for conducting your own research before doing so.
5. Your wallet, your keys, your responsibility
You are solely responsible for the security of your wallet, devices, private keys, seed phrases and credentials, and for every transaction signed with them, whether or not you authorised it. We can never recover them and will never ask you for them. Anyone asking you for a seed phrase or private key in our name is attempting to defraud you.
You are solely responsible for reviewing every transaction before you sign it — the assets, the amounts, the recipient, the approvals granted, the network and the fees. You are responsible for the token approvals you grant, including their scope and duration, and for revoking them if you wish. You are responsible for determining, reporting and paying any taxes that arise from your activity; we do not withhold, report or advise on tax.
6. Quotes are indicative — no guarantee of price or execution
Any quote, rate, route, output amount, price-impact figure, gas estimate or similar number shown by the Interface is indicative only, is computed from data that may be incomplete, delayed, cached or wrong, and is not an offer, a commitment, a reservation of liquidity or a guarantee of any outcome. Nothing is reserved for you until a transaction settles on-chain.
Marketing language such as “best execution”, “best price” or “best route” describes an objective of our software across the venues it happens to index at a given moment. It is not a promise, warranty or representation that any particular quote, route or settled price is the best available, optimal, competitive, or better than any alternative, whether on another venue, another aggregator, or the same venue moments later. Markets move between quotation and settlement, and the amount you actually receive may be materially worse than the amount quoted, subject only to any minimum-received parameter you yourself set.
You choose your own slippage tolerance. Setting it permissively can result in a materially worse execution price, including as a result of deliberate exploitation by third parties; setting it tightly can result in failed transactions for which network fees are still charged. Both consequences are yours.
7. Fees
Using a blockchain network costs network fees (gas), which are paid by you to network validators and are never received by us. They are non-refundable, including where a transaction fails, reverts, or is not included.
We may charge, or may in the future charge, a fee for use of the Interface, which may be taken as a portion of a swap’s output or by any other means, and which may be changed at any time without notice. Third-party venues, market makers and protocols charge their own fees and spreads, over which we have no control and for which we have no responsibility.
8. Assumption of risk
You acknowledge and accept that using digital assets and blockchain-based software is inherently risky, experimental and may result in the total loss of everything involved. You assume all such risk. Without limiting the generality of that statement, you expressly accept the following risks, each of which may cause partial or total loss:
- Software defects. The Interface, our routing engine, our smart contracts and every contract they interact with may contain bugs, errors, defects, logical flaws, mispriced curves, incorrect state or unforeseen behaviour, whether or not audited. An audit is not a guarantee of anything.
- Exploits, hacks and attacks. We, our infrastructure, our smart contracts, our domains, our DNS, our hosting, our dependencies, our build pipeline, and any protocol, venue, bridge, oracle, wallet or third party the Interface interacts with may be hacked, exploited, compromised, drained, spoofed, phished, hijacked or otherwise attacked, including by a malicious insider or a supply-chain compromise, and including in ways that cause the Interface to present you with a transaction that harms you. You accept this risk in full.
- Adversarial trading. Public transactions are visible before they settle and may be front-run, back-run, sandwiched, censored, reordered or otherwise exploited by validators, searchers, builders, bots and other market participants, reducing or eliminating your proceeds.
- Market and liquidity risk. Prices are volatile and may move adversely between quotation and settlement. Liquidity may vanish, be withdrawn, or prove to have been illusory. Slippage, price impact and failed or partially filled transactions are ordinary outcomes.
- Network risk. Blockchains may congest, halt, fork, reorganise, suffer consensus failures, change rules, deprecate features or become unavailable. Transactions may be delayed, dropped, replayed or reverted. Fees may spike without warning.
- Data risk. Prices, balances, token metadata, statistics and chart data are sourced from third parties and from our own indexing, and may be stale, incomplete, unavailable, manipulated or simply incorrect. Oracles may fail or be manipulated.
- Token risk. A token’s contract may be upgradeable, pausable, blacklistable, mintable without limit, fee-on-transfer, rebasing, honeypotted or outright malicious, and its behaviour may change after you acquire it. A token may be worthless or become worthless.
- Counterparty risk. Third-party venues, market makers, RFQ counterparties, bridges and protocols may fail, become insolvent, withdraw quotes, refuse settlement, act in bad faith or be sanctioned.
- User error. Sending to a wrong address, approving a wrong contract, trading a look-alike token, choosing a wrong network or mis-setting a parameter is generally irreversible and unrecoverable.
- Regulatory risk. The legal treatment of digital assets and of decentralised software is unsettled and may change, possibly retroactively, and may render your holdings or your activity illegal, taxable, restricted or worthless.
- Availability risk. The Interface may be modified, suspended, degraded, rate-limited, geoblocked or discontinued at any time, without notice, permanently, including while you have a transaction in progress.
You represent that you are financially and technically sophisticated enough to understand these risks, that you have made your own assessment, and that you are not relying on us for any of it.
9. Disclaimer of warranties
To the fullest extent permitted by applicable law, we, our affiliates, and our and their respective founders, officers, directors, employees, contractors, agents, service providers, licensors and advisers (together, the “Wraxyn Parties”) disclaim all warranties, including any implied warranty of merchantability, fitness for a particular purpose, title, quiet enjoyment and non-infringement, and any warranty arising out of a course of dealing, usage or trade.
Without limiting that, the Wraxyn Parties make no warranty and give no undertaking that: the Interface will be available, uninterrupted, timely, secure, accurate, complete or error-free; that defects will be corrected; that the Interface or its infrastructure is free of viruses, malicious code or other harmful components; that any quote, route, price or figure is accurate, current or achievable; that any transaction will succeed, settle, settle at any particular price, or settle at all; that any smart contract will behave as documented; or that the Interface, our contracts or any third party will not be exploited, hacked or compromised.
No advice or information, oral or written, obtained from us or through the Interface creates any warranty not expressly stated here.
10. Limitation of liability
This exclusion applies to every kind of loss, whether direct, indirect, incidental, special, consequential, exemplary or punitive, and specifically includes loss of digital assets, loss of value, loss of profits, loss of revenue, loss of anticipated savings, loss of business or opportunity, loss of goodwill, loss of data, cost of substitute services, and any loss arising from: a defect, bug or failure in any software or smart contract; any exploit, hack, attack or compromise, including of us; any inaccurate, delayed, stale or unavailable quote, price or data; any failed, reverted, delayed, front-run, sandwiched or reordered transaction; slippage or price impact; any act or omission of any third party, venue, market maker, oracle, wallet, bridge, node provider or blockchain network; any unauthorised access to your wallet; or any suspension, restriction or discontinuation of the Interface.
It applies regardless of the theory of liability — contract, tort (including negligence), strict liability, statute or otherwise — and applies even if a Wraxyn Party has been advised of the possibility of the loss and even if a limited remedy is found to have failed of its essential purpose.
Where liability cannot lawfully be excluded in full, the total aggregate liability of the Wraxyn Parties to you for all claims arising out of or relating to the Interface or these Terms is limited to the greater of (a) the total fees you actually paid to Wraxyn for use of the Interface in the three months immediately preceding the event giving rise to the claim and (b) USD 100.
Nothing in these Terms excludes or limits liability for fraud or fraudulent misrepresentation, for death or personal injury caused by negligence, or for any other liability that cannot lawfully be excluded or limited. Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages; in those jurisdictions the exclusions and limitations above apply to the maximum extent permitted there, and the remainder of this section continues in force.
11. Indemnification
You will indemnify, defend and hold harmless the Wraxyn Parties from and against any and all claims, demands, actions, proceedings, damages, losses, liabilities, penalties, fines, costs and expenses (including reasonable legal fees) arising out of or related to: your access to or use of the Interface; your transactions or digital assets; your breach of these Terms; your violation of any law or of the rights of any third party; or your tax obligations. We may assume the exclusive defence and control of any matter subject to indemnification by you, at your expense, and you will cooperate with us.
12. Release
You release the Wraxyn Parties from any and all claims, demands and damages of every kind and nature, known and unknown, arising out of or in any way connected with any dispute you have with any third party in relation to the Interface, including any venue, protocol, counterparty, token issuer, wallet provider or other user. If you are a California resident, you expressly waive California Civil Code §1542, which says: “A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.” You waive any equivalent provision of any other jurisdiction.
13. Third-party services and content
The Interface links to, depends on and displays content from third parties — blockchain networks, RPC and node providers, wallets, price and metadata services, liquidity venues, market makers and analytics providers. We do not control them, do not endorse them, are not responsible for them, and give no warranty about them. Your use of a third-party service is governed by that third party’s own terms, and any dispute is between you and them.
14. Intellectual property and acceptable use
The Interface, its design, its content and all related intellectual property are owned by Wraxyn or its licensors. Subject to these Terms, we grant you a limited, personal, revocable, non-exclusive, non-transferable, non-sublicensable licence to use the Interface for its intended purpose. All other rights are reserved.
You will not:
- use the Interface in a way that violates any law or these Terms, or that infringes anyone’s rights;
- interfere with, disrupt, overload or attempt to gain unauthorised access to the Interface or any related system or network, or circumvent any rate limit, access control or geographic restriction;
- scrape, harvest or extract data at a scale or in a manner that degrades service for others, or introduce any malicious code;
- reverse engineer, decompile or attempt to derive the source of any non-public component, except to the extent that restriction is unenforceable by law;
- use the Interface to manipulate a market, to engage in wash trading, or to disguise the origin of assets;
- misrepresent your affiliation with us, or use our marks without written permission.
15. Suspension, modification and termination
We may, at any time and without notice or liability to you, modify, suspend, restrict, geoblock, rate-limit or discontinue the Interface or any part of it, and may refuse access to any person, address or wallet at our sole discretion. These Terms remain in effect for as long as you use the Interface; sections 3–14 and 16–18 survive any termination.
16. Governing law, arbitration and waivers
These Terms and any dispute arising out of or in connection with them or the Interface are governed by the laws of England and Wales, without regard to conflict-of-laws rules, and without regard to the United Nations Convention on Contracts for the International Sale of Goods.
Any dispute, controversy or claim arising out of or in connection with these Terms or the Interface — including its existence, validity, interpretation, performance, breach or termination — will be referred to and finally resolved by binding individual arbitration under the LCIA Rules, which are deemed incorporated by reference. The seat of arbitration is London, England; the language is English; the tribunal is one arbitrator. Judgment on the award may be entered in any court of competent jurisdiction.
Any claim must be brought within one (1) year after the cause of action arises, or it is permanently barred. Nothing in this section prevents either party from seeking urgent injunctive relief from a court of competent jurisdiction. Where mandatory consumer-protection law in your place of residence gives you a right to bring proceedings in your local courts or under your local law, that right is unaffected.
17. General
These Terms, together with the Privacy notice, are the entire agreement between you and us about the Interface and supersede any prior understanding. If any provision is held unenforceable, it will be modified to the minimum extent necessary or severed, and the rest remains in force. Our failure to enforce a provision is not a waiver of it. You may not assign these Terms; we may assign them freely. Nothing here creates a partnership, joint venture, employment or agency relationship, and there are no third-party beneficiaries other than the Wraxyn Parties. We are not liable for any failure or delay caused by events beyond our reasonable control. Headings and the summary box are for convenience only and do not affect interpretation.
