🏆 iOS Contest 2025
Prize fund: Up to $50,000
Deadline: 23:59 Dubai time on December 26, 2025
Who can participate: Everyone
📱 Telegram is hosting a contest for iOS developers to bring Liquid Glass effects to older versions of iOS.
THE TASK
Implement custom versions of some of the Liquid Glass effects and the relevant interface flows into Telegram for iOS so these appearances work on iOS 18 and older.
You must precisely replicate the animations and look and feel (highlight on tap, scale-up, bounce, and stretching) on the glass elements. This applies in particular to:
– The tab bar
Omit background blur behind the bar itself, while preserving the glass lenses’ ability to blur the bar’s own content.
– Buttons
This includes attach menu icon, voice and video message recording buttons, etc.
– Switches and sliders
Only the moving element itself should apply blur.
Contest Requirements:
– Support for iOS 18 is mandatory.
– No third-party UI frameworks or new dependencies are allowed.
– The submission must be consistent with the existing Telegram for iOS codebase. You may reuse what is already included in the app's codebase.
– Changes must not negatively affect performance, memory usage, or app stability.
We will announce detailed submission instructions closer to the deadline. The final submission must be your implementation integrated into Telegram for iOS, not a standalone demo app.Читать полностью…

🏆 Telegram Contest for JavaScript Developers, Round 1: Results
After many hours of testing and deliberation, we are now ready to announce the results!
Reworking a text editor – essentially a core component of a messaging app – posed numerous challenges due to the wide range of formatting options and other entities, such as custom emoji.
None of the contestants were able to secure first place, yet we have increased the prize fund for Round 1 by more than 13% to fairly recognize the efforts of the participants.
The judges unanimously agreed to move forward with a second round – which begins immediately.
This time, only the winners of Round 1 will be eligible to participate. More details – in the post below.
And now – meet the winners!
2nd PLACE – $3,000
🥈 Huge Cobra
🥈 Hip Hyena
🥈 Cuddly Lion
🥈 Posh Ram
🥈 Small Fly
🥈 Nice Elk
3rd PLACE – $2,000

4th PLACE – $1,000
🎖 Ace Squid
🎖 Slim Piranha
🎖 Fit Shark
🎖 Desert Falcon
🎖 Fluffy Yak
🎖 Tactful Whale
🎖 Small Dragon
🎖 Shiny Cat
We will publish a detailed list of issues for each submission within the next 72 hours on contest.com.
We are attaching a breakdown of the Final Results for each submission.
1. Final Results:
Initially, for preliminary testing published on contest.com, we ran each test in a separate process. This allowed us to fully evaluate even solutions that crashed or hung on specific tests. However, this method disrupted many participants' performance optimizations and introduced substantial noise into the results.
Therefore, for the final evaluation, we executed all tests in a single process using a grader closely resembling the provided contest-grader.cpp. Consequently, solutions that crashed or hung on any test received a final score of 0.
2. Post-Contest Corrections:
After announcing preliminary results, several participants submitted bug fixes via comments on contest.com. Although we typically do not accept post-contest corrections, one corrected solution turned out to be significantly faster than any solution submitted during the contest. As an exception, we decided to evaluate all corrected submissions and include them in the final standings. To maintain fairness, these late submissions incurred a 20% penalty on the prize amounts awarded.

Design Contest 2025: Submissions
New deadline: 23:59 on December 16 (Dubai time)
We will announce separately once we start accepting your works. We are giving you an extra 24 hours to properly prepare your submissions.
SUBMISSION GUIDELINES
Your submissions will have two core parts:
1. A Telegram channel – which must contain:
– A table of contents – a pinned message with navigation links to the content below. It may also include a Figma project link;
– Static mockups (include both Android and iOS with either theme for each platform) – please upload them as compressed images for better accessibility (use the in-app HD resolution). For readability, you may separate them by sections or blocks;
– Your motion demo uploaded as a playable video – it must be the very last message in the channel.
2. An archive – which must contain:
– All static mockups (both day and night themes for Android and iOS) in .png format, properly structured into folders;
– Your motion video in its original resolution;
Optionally, you may also include the source files for your project (e.g., .aep files).
Note: Your channel may stay private until the deadline. Make sure you assign it a username after the deadline while not revoking the original private link you will be submitting. There is no need to upload any archives to the channel. (You will only upload it to the bot – we will share the details later.)
🏆 Design Contest 2025
Prize fund: $50,000 or more
Deadline: 23:59 Dubai time @ December 15, 2025
Who can participate: Everyone
📱 Telegram announces its most epic Design Contest, where top prize winners will each secure $10,000 and may also get a chance to join the Telegram Design Team.
THE TASK
Design a concept for Telegram Nodes entirely from the ground up, while preserving the familiar components of Telegram’s interfaces. It must feel seamless and aesthetically compelling while remaining clear and intuitive for users.
Nodes act as separate instances within the app that help users organize and streamline their communication flows – from personal to work. Nodes go far beyond simple chat folders or groups with topics enabled.
You may think of them as Discord-like servers or Slack-style workspaces that can contain multiple chat types, including voice and video chats, support in-depth admin management and user roles.
Users who join Telegram Nodes can set a profile picture, bio, and name that differ from their main account. They can then switch between Nodes and their main Telegram inbox – for example, via the left-side menu, which lists all their Nodes alongside any other Telegram accounts they’re logged into.
1) The layouts can be implemented as static .png files. For the animation demos, use .mp4 format (without sound).
Source files and properly structured Figma projects are also welcome.
2) For included videos, you must also provide several static .png images from each video that serve as a storyboard.
3) If you use complex animated icons, they must be in lottie json or .tgs format.
🏆 Telegram Android Contest 2025, Round 1
🎉 This contest turned out to be one of the most successful and fruitful we’ve ever held.
👋 We’re pleased to welcome so many new participants from around the world who joined one of the most challenging coding competitions.
🧱 Out of 90 initial entries, the number of actual app submissions was slightly lower – and we had to further discard some that were either empty or non-functional.
🛠 The Telegram Android Team had to rebuild a couple dozen apps that either didn’t follow the submission guidelines or broke something – so a 10% penalty was applied to their winnings accordingly.
🤑 Given the number of participants and the overall quality of entries, the judges decided to double the prize fund, boosting it to $100,000. This way, we ensured that no worthy submission would be left behind and our recognition could be fairly distributed among all of you who participated.
⏰ After tens of hours spent reviewing all the apps, we can say with confidence – many have far exceeded our expectations. Congratulations, and our deepest thanks to everyone who took part in the competition.
Please meet the winners!

There is one more thing.
Although the winner list cannot be stretched further, we’ve decided to increase the prize fund anyway and award even more submissions with bonuses – each contestant in the list below will receive a bonus of $300. We strongly advise you to keep these bonuses – they may be of a great use for R2.

ContestBot is now ready to accept submissions for the Android Contest 2025, Round 1.
⚠️ Deadline reminder: July 11, 23:59 (Dubai time). Late submissions will not be accepted.
Start the bot, choose “Android Contest 2025 R1”, answer the bot’s questions, then send:
- An .apk file (release build). Make sure your code uses your own api and package ID, and that login works with the production server in the submitted build.
- A link to the commit on a public GitHub repository, forked from the Telegram-Android repository.
Note: Your repository may stay private until the deadline. Entries that are not using their own package id will be penalized.
We are pleased to issue the following clarifications regarding the Android Contest.
Q: Do I need to build these screens as a standalone project?
A: You must implement the new screens directly into the Telegram for Android app, fully preserving all existing profile features. To sum up – the new design flow must replace the current one.
Q: How will I submit my work and what will I need to provide?
A: You’ll need to submit both: an .APK file, and a link to your GitHub repository. For reference, here are the submission guidelines from one of our previous Android contests.
Q: Can we get the source files for the design mockups and animated demo?
A: Please use the files that have already been provided.
Q: Can I use X, Y, Z?
A: You must use Java without any third-party UI frameworks – and you should avoid introducing new dependencies into the project. To sum up – any changes you make must remain consistent with the existing codebase.
Q: What are the floating icons that get hidden when a profile is collapsed?
A: These icons come from either the custom profile appearance or from an active gift. For reference, check out @durov.
Q: Can we further utilize the camera cutout position on certain devices?
A: Absolutely.
Q: Do I really need to build the profiles from scratch?
A: We do not impose any restrictions on whether you should build it from scratch or not – focus on the outcome from the user’s perspective. What matters most is the quality and polish of the final result. That said, a from-scratch approach would be more beneficial in the context of eliminating legacy bugs.
Q: Can we have mockups for the Settings screen?
A: Feel free to implement this screen as you see fit. We consider this as a bonus task.
Q: Which link should we send in 'Profile Default 3.png'?
A: If the other party has incoming calls restricted, send them a link via 'Calls' → 'Create Call Link'.
Q: The icons provided earlier have a solid background.
A: We apologize for the inconvenience. We are attaching below the updated icons.
