SUSCRIBO is a digital web3 platform for electronic contract signing that simplifies the legal and financial transactions of businesses. It caters to clients seeking efficiency, cost reduction, time savings, and reduced physical contact in contract processes. SUSCRIBO offers key technological, security, and analytical solutions to enhance commercial, legal, and financial management.

SUSCRIBO leverages mainstream e-signing and contract lifecycle management with the legal tokenization of the assets and liabilities represented by those contracts. By enabling faster turnover of otherwise paper-heavy business transactions, SUSCRIBO materializes a digitally represented and managed balance sheet.

Digital contracts have the potential to automate a wide range of transactions and services across all business sectors. They provide a secure method of transaction that maximizes efficiency, resulting in cost reduction and reduced legal risks.

  • Minimize human labor involvement.
  • Eliminate execution intermediaries.
  • As agile as the available interconnection infrastructure.
  • Easy access.
  • Ensured security.
  • Introduce technological autonomy into processes.
  • Cost-effective.
  • Adaptable to all types of businesses.

SUSCRIBO transforms e-signing from a paper like digital instance into an actual business transaction trigger that accelerates turnover of otherwise sluggish assets. We do this by merging traditional CLM, from e-signing to obligation management, with web3 capabilities to create legal and financial digital objects you can transact and settle seamlessly.

Plus, SUSCRIBO can work together with older web2 contract management and electronic signature tools, bringing its web3 powers to the mix.

None. SUSCRIBO is the first service that enables electronic signature and the management and automation of contractual obligations expressed as digital objects on a blockchain. This advantage allows legal titles susceptible to trade to be securely and swiftly transferred between parties, even with a price exchange, all on a secure decentralized ledger.

Numerous and all positive. Users won't need to travel from one place to another, will receive immediate support for their actions, and, most importantly, their transactions will be conducted securely, quickly, and effectively, without wasting countless hours on travel, queues, and additional expenses.

Digital contracts are gaining ground in all sectors. Their application can range from something as simple as individual employment contracts to rental agreements and comprehensive corporate workflows in sectors such as real estate, automotive and mobility, private banking and other financial services, telecommunications, insurance, international trade, appliance and retail commerce, energy, public procurement, supply chain, and public sector administrative contracts. All these benefits are expanded when digital contracts become tradable digital objects, unequivocally identified in an enterprise grade blockchain, turning typically illiquid assets and liabilities into liquid ones.

As a company born in the era of enterprise cryptography, SUSCRIBO takes information confidentiality and security very seriously. In general, the technology provided by SUSCRIBO to its clients complies with European standards for data confidentiality and security under the guidelines of the General Data Protection Regulation (GDPR), known for being among the most stringent in the world.

The GDPR has been in effect since May 25, 2018, and aims to protect user data, particularly personal data, and how organizations process, store, and eventually dispose of that data when it is no longer needed. The law provides individual control over how companies can use information directly and personally related to individuals and establishes very strict rules governing what happens if there is a breach of personal data access and the penalties that organizations may face in such cases.

The systems offered by SUSCRIBO are developed by experts native to the era of enterprise cryptography.

For our users' content, we use "at rest" and "in transit" encryption systems up to the point where the user receives or uploads content, all using AES-GCM encryption. The content is also validated because it has been recorded and collected using a SHA256 hash over its content and location. This means there is constant assurance that the content is as required and expected. Finally, the content is passively stored in a top-tier cloud where providers add an additional layer of encryption. Many of the mentioned steps are based on proven open-source implementations and can be verified by advanced users seeking to familiarize themselves or ensure the process.

As mentioned earlier, the services offered by SUSCRIBO comply with European privacy standards, which are the strictest and most pro-user in the world.

The contract digitization functionalities work in all countries worldwide. It's worth understanding that, as a general rule, the digitization of contracts is nothing more than the transition from traditional formats to more modern ones in contractual matters. Legislation around the world, with very few exceptions, has provisions on electronic signatures and contracts based on the recommendations of UNCITRAL, a United Nations organization dedicated to such matters.

Thus, if digital or electronic contracts have the same validity as traditional contracts, the fact that their flow is secured with technology does not diminish their legal validity in any case.

That being said, certain things vary from jurisdiction to jurisdiction: the validity of certain electronic signatures in comparison to others, for certain uses, may require verification under local law. Similarly, certain types of contracts may be subject to specific formalities and requirements, such as public contracts or contracts requiring notarial procedures. In such cases, the digitization of these contracts may require validation with the respective legal teams. SUSCRIBO offers its network of legal partners for this purpose.

Finally, the automation of tasks based on blockchain, or smart legal contracting, may require legal validation in certain jurisdictions.

During Use

Creating a contract template is easy. All you need is the template text in a text file (popular extensions .doc or .docx). Within the text, consider "variables" as those texts that will change when the template is filled to transform it from a generic document into a contract. These variables typically include things like the parties involved, the subject matter or price, deadlines, or even signatures.

SUSCRIBO's variable nomenclature is simple and consists of using a keyword to identify and remember each variable, enclosed in curly brackets. For example, to introduce a variable in a template to represent and call a price, you could name it {{ price }}. This way, when manually creating a contract from a template or through an external system, you can identify that variable and fill in the space between the curly brackets with an actual value.

Use the automatic signature variable: {{ party.signature }}

This variable is composed of two words separated by a period. The first word identifies the party whose signature will be placed where the variable is located. The second word is an automatic call code for the signature instance, telling the system to place the party's signature in that spot. The advantage of this variable is that it's automatic, meaning it associates a signature instance in the contract creation flow (when a party is called to sign) with the identity of that "party" created as party in the contract setup.

The effective date of a document or contract is defined based on the contract text in the "Milestones" section of the Configuration.

This functionality involves the use of relative dates and absolute dates. This means you can configure the system to set the contract date at the moment when the parties have signed, which is a date relative to a "Milestone," i.e., the signature. Alternatively, you can select an absolute date from the calendar, whether in the past, present, or future, which becomes the "Milestone" for the effective date.

When configuring a template or contract, you can use select between dynamic variables so the date showing in your contract comes from an absolute calendar day or it derives from date of signature. 

The format you will see in the contract can be modified. In the Settings/Organization Date and Time section you will be able to select the format you would like your contracts to show dates: 

If you're in the USA or want to use USA notation, use this guide:

MMMM d, yyyy
The result will appear like this in your document: January 1, 2020

MMMM do, yyyy
The result will appear like this in your document: January 1st, 2020

In the Settings/Organization Date and Time section you will be able to select

Now If you are creating contracts that you are expecting to perform obligation management events or tasks in different time zones, you better make sure they are set correctly at creation.

Our tool cannot prevent a person from creating rules associated with a contract and making a mistake while doing so. Of course, for such rules to be enforced by the parties, none of them should notice the error during the signing and review of terms, accepting and signing a contract with erroneous settings. Ultimately, this is no different from what happens in ordinary law when people accept terms they later consider incorrect.

From a legal engineering perspective, a contract has a minimum structure that is very similar to how lawyers understand contracts: with intervening parties, subject matter, price, and term. Now, to define the term, there will be a start and an end, just as for defining when and how the price is delivered and paid, some reference to the contract's start and end will be taken into account in some way.

When a "Milestone" of the contract references other "Milestones" of the contract, it's called a relative rule. For example, the item must be delivered or an invoice issued 30 days after the contract is signed. In this case, the relationship is between the signing and the delivery of the item or invoice issuance, regardless of the absolute calendar day when that deadline expires. If the signing date moves, the relative date will also move.

In contrast, if the delivery date or invoice issuance date is related to the calendar independently of other "Milestones," it's an "Milestone" with an absolute rule.

In the Configuration section, under "Milestones," select the repetition option associated with a "Milestone."


The most likely reason is that you don't have signing authority within the organization to which you belong. In such cases, only the legal representative or the person configured as the account with signing authority for that organization can sign. Organizations are determined by the domain of email addresses, which is the part that comes after the "@" symbol, like, for example.

You can verify this in the Configuration/Organization/Team section, where the signing authority levels for the parties in an organization are displayed. Full information is only available to those with administrator privileges in an organization.

Before proceeding, please make sure that you haven't logged into any applications like Gmail, Microsoft, or LinkedIn and that the email address provided is accurate. In case you have logged in with any of these platforms, click on the relevant one and connect to the email account associated with it. If you have forgotten your password, simply click on the "forgot my password" option, enter your email address, and we will send you an email with instructions on how to create a new password.

About E Signatures

An electronic signature is to the digital age and what a handwritten signature was to the era of printing. A proxy for agreements and transactions, it’s an instance that moves the economy.

According to the UNCITRAL model for Electronic Commerce, Electronic Signatures, and Data Messages, electronic signatures have an indefinite duration.

SUSCRIBO is technology-agnostic when it comes to the type of signature its users require. In addition to its native web2 and web3 signatures, SUSCRIBO allows advanced users to integrate other signature technologies into their contractual workflows.

For individual and business use, there are various types of electronic signatures today, such as simple, advanced, and certified or qualified signatures, depending on national nomenclature. Each type can be useful for different transactions, with certified or qualified signatures often required only in certain jurisdictions and specifically for interactions with public authorities.

Simple and advanced signatures are the most common in the modern business world. They involve unique identification of the person using them and contain more information than a handwritten signature. Advanced signatures gather more data, making them more secure and suitable for various transactions. They can ensure identity, timestamp, geolocation, and detect if a document has been modified after signing.

Certified or qualified signatures involve a third party, often a government-authorized entity, to enhance security. They provide a certificate containing exclusive information of the signer, which can be verified using specific software. It also allows checking the certificate's validity and detecting document modifications after signing.

In jurisdictions where certified electronic signatures exist, there are Information Certification Entities, equivalent to notaries in the digital era, responsible for issuing digital certificates. These certificates are used for secure electronic signatures.

SUSCRIBO is technology-agnostic when it comes to the type of signature its users require. In addition to its native web2 and web3 signatures, it allows advanced users to integrate other signature technologies into their contractual workflows.

Yes, you can. SUSCRIBO currently supports two signature technologies as a general implementation: its native web2 signature, which requires authentication via email, and its native web3 signature, which requires a cryptographic wallet. Beyond that, SUSCRIBO allows advanced developers to implement other electronic signature technologies into its transaction and obligation management flow.

SUSCRIBO has invested in several countries worldwide to provide certified electronic signature services for certain acts or contracts requiring special formality, according to each jurisdiction's requirements. Contact a SUSCRIBO representative to confirm if certified signature is available in your country or to plan the use of electronic signature options in your contractual workflow.

In Europe, too, the eIDAS Regulation defines three levels of electronic signature: 'simple' electronic signature, advanced electronic signature and qualified electronic signature. The requirements of each level build on the requirements of the level below it, such that a qualified electronic signature meets the most requirements and a 'simple' electronic signature the least. Electronic signatures were first recognised in European legislation through the Directive on a Community framework for electronic signature (eSignature Directive) adopted in 1999. Since 1 July 2016, electronic signatures in the EU are governed by the Electronic Identification and Trust Services (eIDAS) Regulation. eIDAS provides a predictable regulatory environment directly applicable to all EU Member States to enable secure and seamless electronic interactions between businesses, citizens and public authorities. The European Commission offers detail on a public information page.

In the United States, The Electronic Signatures in Global and National Commerce Act (E-Sign Act), 1 signed into law on June 30, 2000, provides a general rule of validity for electronic records and signatures for transactions in or affecting interstate or foreign commerce. The E-Sign Act allows the use of electronic records to satisfy any statute, regulation, or rule of law requiring that such information be provided in writing, if the consumer has affirmatively consented to such use and has not withdrawn such consent. Subject to certain exceptions, the substantive provisions of the law were effective on October 1, 2000. Record retention requirements became effective on March 1, 2001. The E-Sign Act grandfathers existing agreements between a consumer and an institution to deliver information electronically. However, agreements made on or after October 1, 2000, are subject to the requirements of the E-Sign Act. 

In Peru, the government approved the Digital Signatures and Digital Certificates Regime through Law No. 27269, which grants electronic signatures the same legal validity and effectiveness as handwritten signatures. This law has been in effect since May 29, 2000.

In Colombia, Law 527 of 1999 defines and regulates the use of data messages, electronic commerce, and digital signatures. It establishes the functional equivalence principle of electronic signatures as long as they perform the same functions as handwritten signatures.

In Mexico, electronic signatures were recognized legally even before recent reforms. The Federal Civil Code, published in August 1928 and amended in June 2019, acknowledges the use of electronic means to express consent in contracts.

In Ecuador, electronic signatures are regulated through the Electronic Commerce Law and its regulations since 2002.

The cost of an electronic signature depends on the technology. For example, most simple digital signatures are usually free, included as part of a service. In the case of web2 native signatures in SUSCRIBO, they are free.

For web3 signatures, the cost is associated with the transaction recorded on a blockchain, not the signature itself. Some signature technologies, like certificate-based signatures, may have a cost. In these cases, the cost includes administrative fees and fees to entities authorized by governments.

Yes, in case of any alteration or changes to the document data, the electronic signature becomes invalid after the change.

Similar to handwritten signatures, fraudulent use of an electronic signature can occur, such as someone accessing another person's computer to use their electronic signature. Victims of fraud, whether with electronic or handwritten signatures, can take legal action to prove they were victims of a crime.

Electronic signatures are widely used in documents such as emails, purchases, bank transactions, electronic invoicing, tax declarations, and even legal proceedings. Legislation generally does not limit the use of this technology. Limitations are often due to cultural resistance or reluctance to change by individuals, businesses, or groups benefiting from traditional paper-based practices.

About Web3

Web3 is the new phase of the internet.

Web3 operates differently from traditional internet. Instead of relying on a few servers, it uses a decentralized network. This means that information is managed through a system of many nodes or servers that work together securely. This network is known as a "blockchain".

A blockchain, also known as a "chain of blocks," is like a distributed and secure digital ledger. It is used to record information, automate transactions, and, as a result, manage values. Cryptocurrencies are just one of the things that can be done with a blockchain. It can be applied to many other transactions beyond those related to value, currency or money, which is what Crypto is known for.

A blockchain is composed of several machines-users (called nodes) working together to verify and validate transactions. This is done following specific rules defined in a protocol. This way, each transaction is securely recorded in the giant ledger without anyone tampering with your information.

Experts compare the arrival of blockchain with significant milestones in history, such as the integration of computers in households or the development of the internet. From a business perspective, web3 is related to the arrival of stock markets as a way to democratize capital during colonial time. With blockchains secure registries, a lot of assets that were excluded from digital commerce can now be traded seamlessly on the internet. In other words, blockchain will change the way we understand businesses and society as a whole.
