FAQ / Common Questions

Yes, absolutely. Our contracts are designed to comply with legal standards and are notary-ready. They include all essential clauses required for legal validity, including proper identification of parties, transaction details, payment terms, and dispute resolution mechanisms. Many of our users have successfully used these contracts with notaries without requiring modifications.

Your privacy and security are our top priorities. We only fetch publicly available blockchain data using your transaction hash. We don't store your private keys, wallet addresses, or personal information. All data processing happens securely, and you can download your contract without creating an account. Your transaction hash is only used to retrieve blockchain data that is already public.

While blockchain transactions are immutable, they don't include important legal details like terms of service, warranties, delivery conditions, or dispute resolution procedures. A formal contract provides legal protection, clarifies expectations between parties, and is required for tax purposes, insurance claims, and notarization. It transforms a simple payment into a legally binding agreement.

You can regenerate your contract as many times as needed before downloading. Simply update the information in the form and create a new version. Once downloaded, you can also edit the Word (DOCX) format directly. However, remember that once a contract is signed by both parties, modifications require mutual agreement and should be documented as an addendum.

Our Starter plan is only €1/month with no hidden fees. You get 5 contracts per month in PDF format. This allows you to test our service at an affordable price. If you need more contracts or Word format, we offer affordable Pro and Lifetime plans. We believe in transparency and helping people secure their crypto transactions.

Not at all! Our platform is designed for everyone. Simply paste your transaction hash (which you can copy from any blockchain explorer), and we automatically fetch all transaction details. Then choose a template, review the pre-filled information, and download. The entire process takes less than 2 minutes, even for first-time users.

We currently support Bitcoin (BTC), Ethereum (ETH), BNB Chain (BNB), and Polygon (MATIC). We're continuously adding support for more blockchains based on user demand. If you need a specific blockchain supported, please contact us and we'll prioritize it.

Absolutely! Our templates are suitable for both personal and business use. The Service Agreement template is particularly popular with freelancers and service providers. For businesses with higher volume needs, our Business plan offers unlimited contracts and API access for integration into your workflow.
