Terms of Service

Last updated: 2 June 2026. The legally binding version is the German Nutzungsbedingungen; this is a courtesy translation.

§ 1 Scope

(1) These Terms govern the use of the website seekerbridge.app and the related Android application seekerbridge (together "the Service").

(2) The Service is operated by Mario Hauser, Selchowstrasse 15, 12489 Berlin, Germany ("Provider").

(3) By installing, opening or using the Service, the user accepts these Terms.

§ 2 Description of the Service

(1) seekerbridge is a non-custodial user interface and aggregator for initiating cryptocurrency swap transactions.

(2) The actual swap is performed by the third-party provider Changelly OÜ, Sepapaja tn 6, 11415 Tallinn, Estonia ("Changelly"). The Provider is not a counterparty to the swap and does not enter into a swap contract with the user.

(3) The Provider never holds the user's crypto assets at any time. All crypto assets flow directly between the user's wallets and the swap addresses provided by Changelly.

§ 3 Eligibility

(1) The user must be of legal age (at least 18 years) and have full legal capacity.

(2) Use of the Service is not permitted for persons resident or located in countries where the swap or possession of cryptocurrencies is prohibited, or for persons listed on a relevant sanctions list (e.g. EU sanctions list, OFAC SDN, UN sanctions).

(3) The user is responsible for complying with the applicable laws of their country regarding cryptocurrencies, anti-money-laundering, taxation, and foreign exchange.

§ 4 User responsibility

(1) The user bears sole responsibility for:

  • the security of their wallets and private keys
  • correct entry of payout and refund addresses including memo/tag/extra-ID
  • choosing the correct blockchain (e.g. USDT-ERC20 vs USDT-TRC20)
  • sending the deposit within the time window specified by Changelly
  • the tax treatment of any swap gains

(2) Incorrect addresses, wrong blockchains or late deposits can lead to total and irrecoverable loss of the crypto assets sent. The Provider expressly excludes liability for losses resulting from such input errors.

§ 5 Fees

(1) Use of the app and website is free of charge for the user.

(2) Each swap transaction incurs fees, which are included in the displayed exchange rate:

  • a service fee from Changelly (regularly approximately 0.25%)
  • the blockchain network fee for the payout transaction

(3) A full breakdown is shown to the user before every confirmation.

§ 6 Exchange rates

(1) For a "floating rate" swap, the final payout amount may deviate from the initially shown amount due to market movements during the confirmation period.

(2) For a "fixed rate" swap, the exchange rate is locked at the moment the swap is created. This requires the deposit to arrive within the time frame set by Changelly. Late deposits will be swapped at the floating rate in effect at that time.

§ 7 No investment advice

The Service does not constitute investment, financial, tax, or legal advice. Cryptocurrencies are subject to substantial price, liquidity, and technology risks. The user makes investment and swap decisions solely on their own responsibility and at their own risk.

§ 8 Liability

(1) The Provider is liable without limitation for intent and gross negligence as well as under the German Product Liability Act.

(2) For slight negligence, the Provider is liable only for breach of material contractual obligations (cardinal duties). In such cases liability is limited in amount to the foreseeable damage typical for the contract.

(3) Provider liability is in particular excluded for:

  • damages resulting from non-performance or defective performance of the swap transaction by Changelly
  • exchange-rate losses or unfavourable rates
  • losses caused by the user entering incorrect addresses, memos, or blockchains
  • losses caused by blockchain reorganisations, 51% attacks, consensus issues, or forks
  • losses caused by manipulation, theft, or loss of the user's wallet
  • temporary unavailability of the Service due to maintenance, force majeure, or outages of third parties (Changelly, Hetzner, Google, the Solana network, etc.)

(4) Liability for indirect damages, consequential damages and lost profits is excluded outside of cases of intent and gross negligence.

§ 9 Intellectual property

(1) All rights in the Service, the app, the source code, the brand "seekerbridge" and the logo remain with the Provider.

(2) The user is granted a simple, non-transferable right to personal use of the Service. Reverse engineering, decompilation or resale are prohibited unless mandatory statutory provisions (§ 69d, e UrhG) permit otherwise.

§ 10 Prohibited use

The user is prohibited from using the Service for:

  • money laundering, terrorism financing, or other illegal activities
  • circumventing sanctions
  • swapping crypto assets derived from unlawful acts
  • interfering with the technical integrity of the Service (DDoS, scraping beyond reasonable rate, etc.)

In case of violations the Provider reserves the right to block access to the Service and, if applicable, to inform the competent authorities.

§ 11 Changes to these Terms

The Provider reserves the right to amend these Terms with effect for the future. Amendments are published on this page and take effect 14 days after publication. For material changes, a notice is displayed in the app.

§ 12 Final provisions

(1) German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only insofar as it does not deprive them of mandatory consumer-protection rules of their state of residence.

(2) Place of performance and exclusive jurisdiction for merchants is Berlin.

(3) Should individual provisions be invalid, the validity of the remaining provisions remains unaffected.
