Web 2.5 Architecture

Web 2.5 isn’t just a buzzword — it’s the natural evolution.
We don’t believe in extremes. Web2 is fast, user-friendly, scalable.
Web3 is transparent, traceable, and tamper-proof.
We combine the best of both worlds.

Our Hybrid Infrastructure

• Global CDN distribution: Your content loads instantly from nearby nodes. Lower latency, lower energy footprint, higher efficiency.
• On-chain metadata: We seal cryptographic hashes on-chain to certify authorship and integrity. What’s registered is permanently verifiable.
• Seamless user experience: You interact with the system like any modern website, with powerful guarantees under the hood.

Fast where it matters. Permanent where it counts.

Every U‑NFT:

• Loads fast, regardless of the user’s location.
• Is sealed forever, even if the website goes down.
• Is yours, traceable from the very first second.

We use CDNs to serve files, blockchain to protect rights, and everything is orchestrated to be fluid and user-friendly.
No mandatory wallets. No jargon. No barriers.
Just your creation — certified, visible, and truly yours.

🧩 Phygital Standardization

Bridging worlds with structure and precision

U‑NFT isn’t just a tech experiment — it’s a new standard for the phygital era.

Our system allows any product, idea, or creation to seamlessly exist in both the physical and digital worlds — without losing uniqueness, authorship, or traceability.

Thanks to our consistent structure and content-binding protocols, U‑NFT creates a verifiable and interoperable identity layer for each item, laying the foundation for global phygital certification.

UNFT Proof™ – Your Digital Notary. No Paperwork. No Loopholes.

U‑NFT Proof™ is a digital certification service designed to immutably and verifiably register the existence, integrity, and authorship of any digital file on the blockchain.

Applicable to:

• Ideas, plans, designs, creative works
• Projects in development or completed
• Legally binding contracts and agreements

How does it work?

1. Upload your file (ZIP, PDF, DOC, etc.).
2. Our system automatically generates a unique, entropic SHA-256 cryptographic hash based on its exact content.
3. This hash is recorded on the blockchain, along with the timestamp and your identifier (wallet or user hash).

Note: The original file is not stored. Once the hash is created, the file is permanently deleted from our servers. Only the immutable proof remains.

What does it guarantee?

• Existence: Proves that the file existed at that exact date and time.
• Integrity: Even a comma change alters the hash.
• Authorship: Links the document to you (your wallet or account).
• Immutability: Public, indefinite verification without third-party reliance.

Your Responsibility

You must keep an identical copy of the file you uploaded. Any change — no matter how small (a letter, a byte, a different compression) — will modify the hash and invalidate the verification.

This is exactly what ensures its immutability and legal value.

Confidentiality

If your file contains sensitive information, you can upload an encrypted .zip file.

We don’t need (or want) access to the content to certify it. Protection is absolute: only you know the password. We don’t access, review, or store anything.

That’s exactly why we call our system The Invisible Notary™: it leaves no trace, asks no permissions, and yet generates immutable proof you fully control.

Is it legally valid?

Yes. Cryptographic hash and blockchain technologies are legally recognized for proving authorship, date, and document integrity.

Legal references:

• 🇪🇺 eIDAS (EU Regulation 910/2014): Grants legal status to electronic signatures and timestamps.
• 🇪🇸 Law 6/2020 (Spain): Establishes that hash and timestamp-based seals have legal presumption of validity.
• 🇺🇸 E-SIGN Act: Equates electronic signatures to handwritten ones under U.S. law.
• 🌎 Latin America: Most countries, including Argentina, Chile, Colombia and Mexico, legally recognize electronic signatures and digital evidence under national e-commerce or civil code regulations. If in doubt, you can check how electronic signatures are treated in your country's legislation — in most cases, they're already accepted.

Pricing

• Up to 250 MB → $9.90
• Up to 2 GB → $24.90
• Over 2 GB → Contact us

Pricing applies to a single file per upload. If your content includes multiple documents, you can simply zip them together and upload the compressed file as one.

Need to certify a large project or multiple files regularly? Get in touch — we offer custom plans for frequent users and teams.

We generate the proof. You control it.

The U‑NFT Marketplace: Phygital Made Simple

Our marketplace is designed for creators, collectors, and brands ready to bring physical and digital products into the Web3 space — without needing to be blockchain experts. Thanks to our SmartMinting™ protocol, publishing is effortless and risk-free for creators.

Associating a physical product with a blockchain-based token ensures lifelong traceability, proof of authenticity, and verifiable authorship — even if the object changes hands a hundred times.

You can list NFTs you've already minted elsewhere, or create brand-new and exclusive UNFTs directly through our platform — complete with metadata, media, and ownership logic.

• Immutable Proofs at Publication: Every product listed on U‑NFT is registered on-chain from the start. Metadata is pinned to IPFS at the moment of publication, ensuring integrity and ownership from day one. Images are stored locally until final minting.
• Free Publishing, Transparent Fees: Publishing and listing unique items, NFTs or small series is completely free. For large mystery boxes or pro series uploads, our Pro Plan is available. U‑NFT only charges a small fee on successful sales — no upfront costs.
• Built for the Phygital World: While we support all types of assets, U‑NFT is optimized for phygital goods — fashion, art, music, collectibles, and more. Whether you're selling a physical item, a digital experience, or a hybrid — we’ve got you covered.
• From 1/1s to Limited Series: Publish one-of-a-kind pieces, tokenized originals with full traceability, or limited series with metadata control. Want to make sure your audience gets the real thing? Every token is anchored to verifiable proof.
• Mystery Boxes & Mixed Drops: Creators can publish surprise drops, mixed bundles or progressive reveals — available under our Pro Plan. Perfect for gamified launches and community-driven releases.
• SmartMinting™ Built In: is a hybrid minting standard developed by U‑NFT to combine early IPFS storage, free blockchain metadata registration, and post-sale on-chain tokenization.

Tokenize the Unique. Certify the Unrepeatable.

Have a one-of-a-kind piece — a signed painting, a rare collectible, a physical artwork or digital creation that exists only once? With U‑NFT, you can tokenize it, anchor its existence to the blockchain, and certify its authorship in a verifiable and immutable way. Even better — you can split ownership into shares, allowing multiple collectors or supporters to co-own a single asset. Whether it's a physical masterpiece or a digital gem, U‑NFT lets you turn uniqueness into community-backed value.

This isn't about uploading just another image — it's about turning truly unique objects into proof-backed assets with traceable value. Whether it's art, music, fashion, memorabilia or hybrid creations, U‑NFT gives your work the protection and authenticity it deserves.

Need Help?

From product strategy and collection design to minting and launch execution — our team of certified experts is here to support your vision. And for added peace of mind, every consulting service includes automatic certification of your ideas through our UNFT PROOF™ – The Invisible Notary™.

🚀 Tokenize your first unique asset

The U‑NFT Oracle Engine: Web3 Without the Headache

The Oracle Engine is the core of the U‑NFT system — the invisible powerhouse that brings your creations into the Web3 universe, effortlessly and securely.

Want to mint your artwork, design, or product into a real blockchain asset without touching a single line of code? With the Oracle Engine, you can. Just upload, define your terms, and let the engine handle the rest — from metadata generation to on-chain execution.

Use it to publish your creations on marketplaces, verify their authenticity, or simply keep them safely stored and timestamped — even if you’re not ready to sell yet. Yes, you can mint and keep your treasure in a drawer. We won’t judge.

Already fluent in Web3? The Oracle Engine integrates seamlessly with our Web3 Storage & Pinning service, giving you full control over your data, files, and minting strategy. You decide when to launch, how to structure your token, and where it gets visibility.

Whether you're an artist, a builder, or a brand — U‑NFT puts blockchain power in your hands, with none of the usual friction.

Web3 Storage & Pinning: Your Creations, Forever Online

When you upload a file to a normal server, it lives there — until someone deletes it, changes it, or forgets to pay the bill. Not ideal when you're trying to prove authorship or preserve digital assets.

That's why U‑NFT uses IPFS — the InterPlanetary File System. Sounds spacey, but it simply means that your files are stored in a decentralized way: no single server, no single point of failure.

Thanks to our Web3 Storage & Pinning service, every file you upload is saved on IPFS and pinned — which ensures it stays online, permanently and independently of our platform. It’s like locking your content in a digital vault that can’t be erased, edited or lost.

Even better: this service works seamlessly with our Oracle Engine. You decide whether to publish now, mint later, or just store your work as proof — the control stays with you.

Whether it’s images, videos, documents, or full NFT collections — U‑NFT gives your creations the Web3 foundation they deserve.
