How it all begins.
Many Bitcoiners start with a so-called single security solution: a seed, written down or engraved in steel, safely kept in a safe, in a bank safe deposit box or deposited with friends. What initially sounds secure harbors several problems. On the one hand, this one point of truth is a single point of failure – if it is lost or copied, the entire asset is compromised. On the other hand, the co-custody of such seeds by third parties, such as banks, notaries or professional safe custodians, is not legally permitted in Germany. Because anyone who stores a seed or private key for customers operates a crypto custody business according to the Banking Act – and this requires a complex, expensive BaFin license.
What is SeedPro?
SeedPro is a software-free system for splitting and storing Bitcoin keys (seeds). It is based on the BIP39 standard (Bitcoin Improvement Proposal 39), an established protocol that generates easy-to-remember word sequences for wallet recovery
It includes 2048 English words, chosen to be unique and error-resistant. A typical seed phrase consists of 12 or 24 of these words, which are cryptographically converted into private keys.
SeedPro Customer is aimed at end customers who want to store their Bitcoin keys analogously, in multiple parts, and future‒proof – for family, estate, or personal long-term strategies. SeedPro Institutional extends this principle to banks, notaries, trustees, and family offices, enabling legally compliant custody structures without a crypto custody license. Both models show: The future of Bitcoin custody is not purely digital. It is shared, analog, and humanly understandable – and thus a step back to traditional security.
Security without compromise
Self-custody carries risks such as loss or theft, while third-party providers often bring regulatory hurdles or dependencies. SeedPro solves this by splitting the KeyCodes – and that brings clear added value: No Single Point of Failure: Your seed is not concentrated in one place. Even if a part is lost, your assets remain secure, as a majority is required. This protects against impulsive access, extortion, or accidents such as floods. Thanks to BIP39 compatibility, you can directly use the reconstructed phrase in common wallets such as hardware wallets.

SeedPro and its security components are delivered within 10 days of ordering. Due to their custom-made nature and confidentiality, they are excluded from returns according to the terms and conditions.
What makes a SeedPro fuse special?
There are many attempts to secure wallet seed phrases. However, they are often not equally suitable for everyone. Most are complex and difficult to understand, and elaborate to produce or use. Still others require skill, experience, technical prior knowledge or tools. So far, no safeguards meet the legal requirements for commercial sharing.
SeedPro is at least 2‒part and designed to make securing seed phrases easy, fast and secure. Everyone can use SeedPro and: SeedPro can be combined with all systems and wallets and can be legally shared among partners.
STORABLE
Without loss of security, your secret can be saved.
By converting words into a PositionKey, your seed phrase can only be decrypted with the matching seedlist.
That's why you can now save your keys in various ways. On mobile, SD cards, USB stick, NFC cards or coins, and many more.
DIVISIBLE
SeedPro makes seed phrases shareable for the first time. Whether with private or business partners, children, or external custodians such as notaries, trustees, banks, etc.
Shared SeedKeys are automatically secured in emergencies and inheritance cases through a SplitKey procedure.
SeedKeys are shareable ‒ seed words are not.
INDEPENDENT
Freedom and independence are the most important characteristics of Bitcoin.
That's why Seedpro is independent of technology and manufacturers. Seed phrase recovery must still work years from now without technology, no matter the wallet or manufacturer.
MODULAR
SeedPro can be easily combined and extended at any time, for example, if additional children, life or business partners are to be integrated.
Just as different roles can be assigned to security holders, they can also be changed at any time.
TOOL‒FREE
Seedpro is designed so that you can convert your seed phrase into a SeedKey without the use of tools or technology.
And your seed phrase can be converted back just as easily: without tools or technology.
Only if you want to, you can additionally save your code on stamped metal plates, digital storage and NFC chips, mobile phones, laptops or hard drives.
SeedPro requires no tools and no technology.
Do you need some security tips?
Keep it simple.The simpler your key backup, the easier it can be used by you or your relatives and partners in an emergency.
Do you think beyond your possessions?
Either your Bitcoins find their way to the people you intend them for, or no one ever gets access to them again, or an unauthorized person receives them. When an estate is dissolved, it is not always your next of kin who is first in line, but someone of the 2nd or 3rd degree, or even strangers who liquidate apartments and possessions. If you want automatic succession, trustees, notaries, or vault custodians are a good choice. They may accept components of SeedPro II+.
Do you think your Bitcoins could become valuable?
Start directly with a future-proof security solution and don't wait. Take key management into your own hands if you feel a need for control. Transfer from your account or exchange to your wallet. Seedpro II is a good entry into key security.
Do you have a family?
Make access to keys as secure as possible, but also as easy as possible. Your relatives may not have your Bitcoin knowledge. Seedpro II+ is easy to understand and use. Play with open cards and share information on how your security is built and how it works.
Do you have a business?
Here, due diligence, exact documentation, legal and tax aspects must be considered. Your providers also have the same due diligence obligations towards you in your education. Safe action is not a "nice to have" but a necessity. Seedpro II+ and III+ are a good choice.
Do you manage family assets?
The same requirements apply as for companies. Diligence, education and transparency are crucial here. Owners must also be given access to the keys in emergencies. Seedpro II+ and III+ are a good choice.

Digital sovereignty & traditional custody
With SeedPro Institutional, a system is created that relies not on trust in technology, but on structured collaboration. While classic "single security solutions" place all responsibility in one hand, a multi-part model shifts control to multiple shoulders – without giving it away. This protects not only against loss or theft, but also against impulsive decisions, family disputes, or technological change.
A security model that acts like a bridge between two worlds: the digital sovereignty of Bitcoin and the analog reliability of traditional custody. The loss of one part does not lead to a total loss, and no finder can access the assets with a single piece of information. Even in scenarios such as inheritance, corporate administration, or foundation trusteeship, it can be defined under what conditions access may be granted – for example, through a certificate of inheritance, a notarized release, or the expiry of certain deadlines.

Frequently asked questions about why a seed phrase backup is important and how it works:
Storing your asset keys like PINs, seed phrases, and key codes is one of the most important things to protect your Bitcoin and seed phrases long-term. Because: not your Keys ‒ not your Coins! With a SeedKey, you decide with whom and how you want to protect your seed phrases in the future: Store Bitcoin seed phrases physically, biometrically, or digitally.
1. What problems does SeedProtector solve?
If you want to own your Bitcoin keys, you need a wallet. They are protected with 12/24 secret seed words that form a seed phrase. If you protect your seed phrase only with notes or a steel backup, anyone who finds it immediately has a master key to your Bitcoin. With SeedPro, you can split your keys into individual keys as often as you like, involve people and service providers, and store them however you want. Physically, biometrically or digitally. The division of wallet, PIN and seed phrases, or seed keys, is essential for a legally secure storage concept.
2. Why should one back up Bitcoin seed phrases multiple times?
Imagine losing access to your wallet—be it through theft, technical errors, or a simple moment of carelessness. This happens frequently and has already cost countless crypto owners millions. Seedprotector was developed to eliminate these risks with divided communities, storage media, and secure locations. If your seed phrase is unprotected, anyone can immediately access your Bitcoin. SeedPro converts it into a SeedKey—unique, encryptable, shareable, and securely storable.
3. What makes SeedProtector different from other solutions?
Seedprotector is a security and storage system for Bitcoin. It consists of several backup components that can be legally shared and stored externally. The system is composed of physical and digital security. It meets all legal requirements for Bitcoin custody by individuals and businesses.
We have developed a backup for seed phrases that allows you to decide which storage method is right for you. To be flexible with storage, simply convert your seed phrase into a SeedKey with your unique SeedPro-Seedlist. You'll be amazed how quickly this works and what you can do with it, unlike your seed words.
Seed phrases can now be stored digitally - securely and for others, and no longer pose a fundamental security risk. With a one-time purchase of a SeedPro-Seedlist, you can secure as many seed phrases as you want, now and in the future.
4. How does the backup of seed phrases and Bitcoin keys work?
SeedPro uses a process called Unique Positional Seed Encoding (UPSE), where a BIP39 seed phrase is translated into positional codes. These so-called SeedCodes represent the positions of the seed words within the standardized BIP39 word list (2048 words). The BIP39 word list is individually re-generated in a random order for each user, making the SeedCode unique even with the same words. The BIP39 word list corresponds to the DINA4 format and is printed on aluminum composite panels on the front and back using a secure thermal process. This makes them waterproof, scratch-resistant, UV-radiation-proof, and flame-retardant. Due to its size, it is safe- and file-compatible and not as easy to lose as other, significantly smaller backups.
The BIP39 word list is converted into a matrix with 15 columns (A–O) and 137 rows (1–137). Each entry in the list can thus be uniquely referenced by an alphanumeric code such as "F73".
A standardized 12- or 24-word seed phrase is converted into 12 or 24 of these positional codes: mystery garden rival ... ➔ H79 F61 K44 ...
5. Who needs to split their seed phrases and Bitcoin keys with others?
These can be, for example, individuals who want to arrange a succession with notaries, or families who want to integrate a spouse, children, or relatives. Companies also share responsibilities with executives. Banks or trustees share access options with their customers for credit grants and keep shared and coded keys with themselves or with safe custodians.
6. When are Bitcoin keys shared with others?
whenever several parties want to share access to their Bitcoin, a legally secure system for key sharing is needed. Why? It prevents one person from accessing the assets alone. Sharing enables security against others.
7. Why is a system needed for sharing Bitcoin keys?
A system is always required when certain roles with rights are to be assigned through key sharing. Whenever a commercial or legal partner such as a bank, notary, trustee, vault custodian or family office holds keys for another person or company, either a specific Bitcoin splitting and custody system for Bitcoin keys is needed, or a license from the Federal Financial Supervisory Authority (BaFin) under the Banking Act or the Financial Market Authority (FMA) in Austria or (FINMA) in Switzerland is required for service providers for custody. Custody for others without a license or system is illegal. License violations in the financial sector can be punished.
8. How do SeedPro fuses differ?
SeedPro Consumer is a 2-factor security for normal use. Consisting of a seed list and a paper KeyList for noting down the KeyCode. The code can be stored or copied as desired.
SeedPro Consumer NFC - is the same 2-factor security plus an NFC memory as a card or Bitcoin for saving the code for all sharing purposes. In addition to the noted code on the PaperKeylist, there is another physical and digital backup of the KeyCode on an NFC chip. They are written with conventional, free mobile phone apps, such as NFC cool. Chips can be ordered individually and distributed to security participants as often as desired. Ideal for families with several members or heirs, as well as companies and family offices.
SeedPro Consumer Family is a 3-factor security for family purposes. Consists of a seed list plus 2 acrylic templates. These templates are used to mark the positions of the seed words on the seed list. Why 2 templates? There is a front and a back on the seed list, because there would be too many words for one page. Each page therefore has a template. It simplifies the formation of the seed phrase, as no code has to be reformed. Simply place the template - and the words become visible. Ideal for families with several members or heirs.
SeedPro Consumer Ultra is a 3-factor security for the highest demands. Consists of a seed list plus 1 additional metal plate (Keylist) and an acrylic template. The seed list stores all words, the Keylist stores the selection of words as KeyCode and the PIN, the template stores the order of the words. Ideal for families with several members or heirs, as well as companies and family offices.
9. How does a physical storage of a seed phrase key code work?
Once converted with your secret seed list, you can physically store your SeedKey anywhere and create infinite copies with any material. Whether on sticky notes or paper forms, or on stone, wood or metal - there are no limits to your imagination. Store it wherever you want: On the backs of photos or pictures, in folders on foils or stickers or jewelry such as pendant, rings or bracelets. Carry it with you, keep it at home or together with your seed list with one of our partner safe providers near you. This is only possible with the Key - not with your words!
10. How can seed phrase key codes be stored digitally and biometrically?
Yes, you heard right! A no-go with seed words but allowed with the SeedKey. Because only with your unique and secret seed list will your SeedKey become your seed phrase. Finally, a secure offline production of a SeedKey and storage on your mobile phone, laptop, hard drive, USB memory card, in the cloud or anywhere else digitally is possible. An innovative and definitive solution for storing your SeedKey is the signed and verified follow-up message of your hardware wallet with your wallet address. You can store this signature online and it is guaranteed to belong to your wallet.
If you want to always carry several key codes with you, you can wear them under your skin instead of jewelry and a wallet. They become invisible to everyone and cannot be stolen or lost. With a mini-biometric NFC chip as an implant, you carry your key code on your body - wherever you want. It is invisible and does not affect you. Every modern mobile phone is also an NFC writing and reading device, with which you can then discreetly make your code visible again if you wish. Together with your seed list, you immediately have your seed phrase again as your Bitcoin asset key.
11. Which laws govern the storage of wallets & seed phrases?
The custody of cryptographic keys and wallets is regulated in Germany according to § 1 Abs. 1a Satz 2 Nr. 6 KWG and the crypto custody business, and in Switzerland by the Financial Market Supervisory Authority (FINMA) and in Austria by the Financial Market Authority (FMA). It requires providers to obtain a license, for which there are high regulatory hurdles and evidence of IT security & infrastructure (e.g., HSMs, access management), compliance & risk management, personnel with crypto expertise, compliance with MiCAR and anti-money laundering regulations. These are complex and expensive, which is why very few market participants, such as banks, trustees, notaries, vault custodians, and family offices, currently possess or aim for them. The AMLD5 and from 2024/2025 the new MiCAR regulation (Markets in Crypto-Assets Regulation) regulate the crypto custody business throughout the EU.
The custody of seed lists as part of the Bitcoin security SeedPro by Seedprotector is not considered custody of cryptographic keys or cryptocurrencies within the meaning of the Banking Act and is not subject to licensing requirements in any country.
The constellations of so-called key splitting (Split Key Custody) are not present with SeedPro. A bank, a trustee, or a vault custodian who holds a seed list as a custodian but has no access to wallets is not subject to a licensing requirement, as formally there is no complete crypto custody. The entire word list according to the BIP39 protocol is to be regarded as part of an individual seed phrase and as the complete base set of all possible words.
Only with SeedPro can service providers perform professional custody of keys and wallets even without a license.
