Telegram Mini-App

User Acquisition

Bringing crypto to everyone, everywhere

When I first met the team at Bankii, they had a clear vision.

Make crypto accessible to absolutely anyone, anywhere.

No more puzzling charts, confusing jargon, or overwhelming barriers to entry.

Bankii was building a crypto fintech app that made it easy for people to save, spend, and invest.

Now, their app includes…

  • Crypto-enabled VISA cards (physical/virtual)

  • Multi-currency wallets supporting over 40 blockchains

  • Bank-level security

  • And products to enhance users' crypto earnings.

I was impressed with what they'd created.

As their platform was genuinely solving problems for:

1- Regular people who had been interested in crypto for years but always felt lost when they tried to jump in.

2- Experienced investors who had a solid crypto plan but were sick of high fees, long wait times, and not feeling in control of their own money.

3- Small business owners in places where regular banks weren’t an option.

They had heard crypto could change everything for their business but had no idea where to start or who to trust.

Their product worked great on paper.

The tech was solid, the UI looked clean, and whenever someone made it through the whole signup process, they usually loved it.

And so, the early testers were giving Bankii thumbs up across the board.

But they ended up hitting the same wall that nearly every Web3/Crypto project faces.

The User Acquisition problem that was holding Bankii back

Bankii had built something amazing, but they were struggling to get it into people's hands.

And If you're building in Web3, you can relate to this pain.

You spend months perfecting your product, but when launch day comes... nothing out of the box happens.

Or maybe you get a flood of bot accounts that inflate your numbers but bring zero actual value.

The Bankii team figured out three core problems:

1- Too Much Friction

Even interested users gave up because they had to download an app, create an account, and deal with a complicated setup.

They left before they could see how great the product really was.

2- Weak First Impression

With so many competing projects, they needed something that stood out and delivered value right away.

3- No Engagement Loop

Users would check out the app once, but there wasn't a strong enough pull to bring them back consistently. And without repeated engagement, adoption was slow.

This is where they concluded building a Telegram Mini-App.

At first, they thought the same…

"But we're a serious fintech platform, Not a game or social app."

Exactly the reaction as expected.

It's the same thing I hear from almost every founder when they first think about it.

And so here's why…

Telegram Mini-Apps are ONLY for a "serious" crypto project

The Bankii team saw the potential of Telegram Mini-Apps and reached out to us to bring their vision to life.

They knew the success stories but needed expert help to build something that truly stood out.

When we talked about their project,

I shared our experience building a Telegram Mini-App for EstateX,

Which is a real estate tokenization platform (as serious as it gets).

EstateX went from struggling to hitting 232,903 monthly active users before their token launch.

This led to a higher token price at TGE, a stronger market cap, and ultimately, they raised more funding.

The Bankii team was excited to see these results.

We also showed them why Telegram Mini-Apps work so well.

1- First, you're not fighting an uphill battle.

Your potential users are already on Telegram - 300 million of them use it daily.

No need to convince them to download another app or create another account.

It takes just five seconds to access your mini-app.

2- Second, you can build a real reward system.

Users complete daily tasks

Share with friends

Engage with socials

And earn points that translate to future value in your ecosystem.

You don't pay anything upfront for users,

And they're excited to engage because of the potential future gains.

3- Third, you can create a lightweight, gamified version of your platform.

Something to get people hooked before they ever see your main product.

Think of it as baby steps instead of asking users to take a giant leap.

We looked at the numbers from other successful mini-apps:

  • Notcoin: 40.1M users, $728.20M market cap

  • Blum: 62M users

  • Hamster Kombat: 239M users in 81 days, $185.30M market cap

  • Zenrock (a project we built): 35K users in just 29 days

With these examples in mind, we got to work on Bankii's custom solution.

The custom Telegram Mini-App we built for Bankii

After understanding Bankii's goals, target audience, and unique value proposition…

We designed a mini-app specifically for them that would solve their user acquisition problems.

We didn't want to create just another tap game.

Instead, we created something that fit their mission- making crypto easy for everyone.

We added all the essential features that make Telegram Mini-Apps successful,

While carefully tailoring each one to Bankii's specific needs:

1. A Gamified learning experience

Remember all those folks who find crypto overwhelming?

There are millions of people out there who are curious about crypto but scared by it.

We created a gamified learning platform within the mini-app...

Where users could earn points by completing educational modules about crypto basics,

Security practices, and how to use various Bankii features.

This fixed a real problem for users while also getting them ready to use the main platform.

2. Quest & Reward system

We implemented a comprehensive tasks dashboard where users could:

  • Earn points for daily check-ins

  • Complete social tasks (following Bankii's social accounts, and engaging with content)

  • Refer friends to the mini-app

  • Advance through learning modules and challenges

These points later turned into token airdrops, creating natural growth.

The best part?

Bankii didn’t have to pay upfront for users -people joined in because they saw future value.

3. Simplified Feature previews

Instead of trying to replicate the entire Bankii platform in Telegram,

We created simplified previews of their key features.

Users got a sneak peek of the full platform in a simple, hassle-free way.

For example,

We created a mini-version of their wallet interface...

Where users could test transactions and see how easy it was to manage multiple crypto assets in one place.

This sparked curiosity about the full platform and gave them confidence to use it.

4. Smooth onboarding tour

First impressions matter.

We designed a step-by-step guided tour that started when users first opened the app,

Telling them about each component and feature.

This cleared up any confusion and kept users from dropping off in those crucial first minutes.

5. Powerful referral system

We also added a referral system so users could easily create and share invite links with their network.

Users earned points for each friend who joined through their link,

Creating a snowball effect that in return accelerated user growth.

6. Profile enhancement with rewards

We created a profile dashboard where users could connect their wallets, add emails, and link social accounts...

With point rewards for each piece of information they provided.

This was strategically placed after the initial onboarding to avoid friction,

And allow Bankii to gather valuable user data while users felt rewarded for sharing.

7. Partner rewards dashboard

We built a partnership section featuring other compatible Telegram mini-apps, allowing for cross-promotion.

Users could discover other apps and earn rewards for trying them,

While Bankii benefited from reciprocal promotion on partner platforms.

8. Leaderboards and stats

We added comprehensive leaderboards showing users' performance metrics...

Tasks completed, referrals, points earned- compared to others.

This promoted healthy competition and kept users coming back to improve their standing.

9. Daily streaks system

To keep users engaged,

We added a streak system that rewarded them for logging in and completing tasks daily.

This created a daily habit loop that significantly improved retention rates.

10. In-app store

We built a store where users could spend their points on various items -

24-hour boosts, special access passes, and unique profile customizations.

This gave the points real utility and created a sense of achievement and personalization for users.

From Struggling → Scaling

The Telegram Mini-App became a powerful gateway to Bankii's ecosystem...

Leveraging its unique features in a simplified, engaging format:

  • Their crypto card was showcased with interactive demos.

  • The multi-currency wallet was introduced through simple games.

  • Their earning opportunities were highlighted with quests & rewards.

  • Security features were taught through engaging educational content.

The mini-app effectively addressed all three of Bankii's initial challenges:

  • Users could access the mini-app in seconds, right where they already spent time.

  • The gamified learning experience made it fun and rewarding for users right from the start.

  • The quest and reward system kept users coming back daily, helping them build habits and get familiar with the Bankii brand.

But perhaps most importantly, it connected Bankii with exactly the type of users they wanted to reach-

People curious about crypto who needed a simple, guided way to start.

Is your Web3/Crypto project also struggling with User Acquisition?

If you're facing similar challenges to what Bankii experienced, you're not alone.

Almost every Web3 founder I meet is facing the same struggle.

While many are still focusing on traditional channels,

The smartest founders are leveraging Telegram Mini-Apps to create exponential user growth.

Because here's the thing -

Building an effective mini-app isn't just about slapping together a basic tapping game.

The best Telegram Mini-Apps are built to match your brand, attract the right users, and seamlessly connect them to your main product.

That's exactly what we do, and I share a lot of these insights in my guides.

Just look at what Bankii, EstateX, and many others achieved by implementing these strategies properly.

So at this point, you've got two options

You can dive in and build it yourself (which is totally doable),

Or you can work with people who have:

  • Ready-made components that accelerate development

  • Experience with launching multiple successful mini-apps

  • Proven processes that ensure smooth execution from idea to code, design, strategy

If you wanna see how a Telegram Mini-App could work for your specific project...

Just drop me a message on TG or save a spot on my calendar.

From there we'll see if we're the right fit to build it together.
