Why We Built Our Own Aadhaar eSign Stack at Meon — And Why It’s Different
At Meon, we help businesses so you can go paperless with fast, secure, and legally compliant digital signatures. One of the most critical parts of this is the Aadhaar eSign solution. It is a government-approved way to sign documents using your Aadhaar number and OTP.
But instead of using existing third-party solutions, we have decided to build our own Aadhaar eSign solution from scratch. It took time, effort, and a deep understanding of compliance, cryptography, and user experience. So, why did we do it? And what makes our eSign stack different from others?
In this blog, we will walk you through our journey — the problems we faced, how we solved them, and what sets Meon apart in the eSign ecosystem.
The Problem with Existing eSign Services
When we first explored Aadhaar eSign options available in the market, we found serious limitations, including:
Poor User Experience
Most e Signature services had outdated interfaces. Users had to jump between multiple screens, click confusing buttons, and deal with unclear instructions. This can cause drop-offs and frustration, especially if your users are not tech-savvy.
Slow and Unreliable APIs
Some APIs took several seconds to respond or failed altogether. In a world where users expect things to work instantly, the slow Aadhaar eSign process is not acceptable. You can lose your customers.
Lack of Flexibility
Each business is different. We wanted our customers to be able to customise the Electronic Signature Service flow, branding, and user journey. But most providers offered rigid solutions with little room for change.
High Price
Pricing was often confusing, with hidden costs and high minimum commitments. This made it hard for startups and small businesses to easily adapt eSign services.
Why We Decided to Build Our Own?
At Meon, our goal is to create a digital infrastructure for trust, not just a document signing tool. We knew that if we wanted to deliver reliability, control and user-friendliness, then we had to build the eSign stack from scratch.
What Makes Meon’s Aadhaar eSign Stack Different?
Complete Control from End-to-End
We built and manage the entire Aadhaar eSign process pipeline in-house — from API gateways to cryptographic signature generation, timestamping, and integration with Certifying Authorities (CAs). This gives us full control over:
Security
Performance
Compliance
Customization
So that we can offer a secure and hassle-free signing experience to our customers.
Lightning-Fast Performance
Thanks to our optimised infrastructure, our eSign API responds in under 500 milliseconds in most cases. That’s 4x faster than the average response time of many existing eSign Services providers. This speed improves user experience, especially during high-traffic scenarios. So that you can offer a better experience to your customers.
Built for Developers and Businesses
We designed our API with developers in mind. It's clean, RESTful, and well-documented. You can integrate Aadhaar eSign into your app or platform in less than 30 minutes.
For businesses, we offer modular SDKs and no-code options, too. Whether you are a startup or an enterprise, you can quickly adapt the eSign solution without any heavy investments.
Customizable User Journey
You can fully white-label the signing experience: add your logo, choose your language, customise the OTP screen, and even tweak the flow as per your audience. For example:
A bank can add video KYC before eSign.
An HR tool can capture employee consent before showing the offer letter.
Our system is flexible, so you can design it as per your requirements.
The Impact So Far
Since launching our Aadhaar Electronic Signature Service stack, we've seen:
65% reduction in user drop-offs
99.9% API success rate
Mass adoption across BFSI, HR, LegalTech, and SaaS
Along with that, we are helping thousands of users so that they can legally complete valid signatures without any friction. Your customers can now sign documents even from remote locations with low bandwidth.
In Conclusion
Building our own Aadhaar eSign stack was not easy, but it was necessary. At Meon, we believe digital trust should be secure, fast, and user-friendly. With our eSign solutions, including Aadhaar-based eSign and digital signatures, we are helping businesses so they can streamline their operations.
