Quick Overview
TC eWallet is a blockchain-based mobile digital wallet that digitizes traditional corporate seals into secure, legally valid electronic seals, addressing the slow pace of corporate financial digitalization. Built on global standards like W3C DIDs and eIDAS certification, the platform aims to advance cross-border digital trust for enterprises, financial institutions, and governments worldwide.
What we'll cover
1. Introduction: The Trends and Future of Digital Trust
Every industry now runs on digital trust, but for the financial sector and the corporate world, it underpins everything they do. Which is why it’s no surprise that global demand for digital identity solutions is accelerating at an unprecedented pace.
Think about your own day: online shopping requires verification, banking needs authentication, and countless apps demand proof of who you are. Clearly, digital identity protection isn't optional anymore. It'sfundamental to how we live and work.
Yet skepticism persists, and for good reason. When we share our information online, what actually happens to it?
European Commission President Ursula von der Leyen framed the problem clearly:
“Every time an App or website asks us to create a new digital identity or to easily log on via a big platform, we have no idea what happens to our data in reality. That is why the Commission will soon propose a secure European e-identity. One that we trust and that any citizen can use anywhere in Europe to do anything from paying your taxes to renting a bicycle. A technology where we can control ourselves what data and how data is used.”
Her statement reflects the EU's ambitious vision. Through eIDAS 2.0 legislation (European Commission, 2024), Europe is building a comprehensive digital identity ecosystem designed to restore user control and trust.
But over in Taiwan, there's been a different challenge brewing.
Corporate financial digitalization has progressed slowly, constrained by structural limitations that have held businesses back for years. Recognizing this issue, the Financial Supervisory Commission (FSC) launched the "Corporate Digital Identity Verification Loan Platform Pilot Program" to catalyze change.
This initiative set the stage for our TC eWallet, a digital wallet solution built for mobile devices and designed to break through these long-standing barriers.
More than just a digital identity management tool, TC eWallet represents a transformative shift in how enterprises and individuals approach digital authentication and signing. By placing "digital trust" at its foundation, TC eWallet directly addresses two critical pain points: secure identity verification and seamless digital document signing.
It's a practical solution to a complex problem that's been limiting Taiwan's corporate sector for far too long.
2. The Corporate Seal Dilemma: Challenges in Digital Transformation
Walk into any business anywhere in the world, and you'll likely still find official stamps and seals serving as marks of authority and authenticity, though their forms and applications vary widely.
East Asia
— Corporate chops/seals (known as yìnjiàn in Chinese, hanko in Japan, ingam in Korea) are legally binding
— Required for contracts, banking, corporate resolutions, and financial transactions
— Often equal to or stronger than handwritten signatures
Southeast Asia
— Mostly optional by law in Vietnam, Singapore, Indonesia, Philippines, Thailand, Malaysia, except in specific statutory, regulatory, or internal corporate scenarios
— Widespread use in commercial & government contexts for authentication, convenience, or custom
— Used for contracts, regulatory filings, and internal authorizations
— Stamp = company identity
South Asia
— Extensive government and commercial stamp infrastructure
— Revenue stamps, departmental seals, and company stamps support public administration, taxation, and commerce
— Hybrid system: Signature + stamp together for validity
Middle East (GCC and neighboring markets)
— Company stamps required for business authorization
— Common on contracts, invoices, banking, and government submissions
US, UK, EU & Canada
Stamps serve specialized functions rather than general validation:
— Notary stamps/seals authenticate legal, real estate, and certified documents
— Corporate seals formalize company filings and resolutions
— Signature stamps allow authorized signatories to execute routine documents
— Medallion Signature Guarantees (US only) validate high-value securities transfers
— EU & UK: Official seals are important for notarial acts, public administration, and civil-law company filings, while private contracts rely mainly on handwritten or qualified electronic signatures
Taiwan's business culture, too, has a long history with corporate seals and official stamps.
These physical markers of authority have been central to operations for decades. But what worked in the old-school pen & paper world now creates friction in the digital one.
Paper-based workflows tied to traditional stamp culture slow down processing, require manual handling, waste resources, and harm the environment, creating bottlenecks throughout corporate finance.
For companies expanding internationally or scaling operations, these constraints become increasingly problematic.
But TC eWallet's electronic seal (e-seal) functionality offers a way forward. It digitizes traditional corporate stamps while leveraging blockchain's immutability to guarantee authenticity and legal validity for every signature.
This results in streamlined internal operations, reduced fraud risk, and accelerated digital transformation across corporate finance.
3. How TC eWallet Works: Technology That Delivers
TC eWallet's architecture rests on three integrated components:
Digital Wallet Backend System
Digital Wallet Mobile App
Blockchain Technology
This combination delivers both robust security and operational flexibility.
The backend system gives enterprises comprehensive control. Organizations can manage customer assets, seal data, and documents while maintaining strict security and regulatory compliance.
Meanwhile, the mobile app puts power in users' hands, enabling them to access, verify, and sign documents from anywhere at any time.
Security is built into every layer. Private keys never leave the user's device, eliminating the vulnerabilities that come with centralized storage. If your keys aren't on a server, they can't be stolen from one.
Blockchain technology provides the final piece. TC eWallet brings blockchain-based NFT technology into real-world use, turning traditional company stamps into trusted digital identity markers for corporations.
This approach ensures that every digital signature and document record is immutable and non-repudiable, while building verifiable trust in the signing process and laying the foundation for global standardization of digital seals.
4. TC eWallet + SelfieSign: Verifying Identity Beyond Doubt
For online document signing, TC eWallet integrates with SelfieSign's AI-powered video e-signature verification, forming an ecosystem where identity-to-person binding is secured through multi-layered AI biometric authentication.
Here's how it works: Every signing transaction uses SelfieSign’s video-based e-signature technology to record the complete process in real-time, capturing not just the signature but also the time and location. The system then generates an encrypted, non-repudiable SVS (Selfie Video Signature) file.
This provides enterprises with best-in-class digital trust infrastructure.
For end users, this translates to confidence in conducting digital transactions, knowing they're protected from identity theft and data leakage through immutable and non-repudiable records that simultaneously contain both biometric data and e-signatures.
5. Built for Global Standards, Ready for Global Markets
International compliance isn't an afterthought for TC eWallet. It's foundational.
The platform adopts W3C Decentralized Identifiers (DIDs) and Self-Sovereign Identity (SSI) standards, placing it at the forefront of global digital identity frameworks.
SelfieSign's video electronic signature technology is also officially registered under Taiwan's Ministry of Digital Affairs electronic signature capability registry and is eIDAS certified. This combination positions TC eWallet among the world's most compliant digital wallet solutions.
The implications extend far beyond Taiwan.
Enterprises gain a clear pathway to international markets. Users across different countries receive standardized digital identity authentication and document verification services.
Global digital trust advances, one transaction at a time.
