🏆 Smart Contract Cracking Competition: Results

While the contest offered a challenging task with a tight deadline, we were pleased that many developers seized this opportunity to thoroughly research and test the smart contract for the Auction Platform. Their accepted discoveries have already been merged into the main code branch.

As nobody cracked the smart contract, there is no winner in this competition.

⭐️ Kooky Swallow, Chic Dolphin and Shiny Giraffe independently spotted the same issue that required several conditions to be exploited. Each of the three participants will get $10,000. Shiny Giraffe also receives an extra $500 for pointing out an issue with a missing check in one function.

We are happy to announce that the following contestants are also eligible for rewards – for suggesting useful optimizations and minor code tweaks. For identical issues, the earliest submitted pull requests are considered eligible for a reward.

✨ Honorable Mentions
• Wise Pony is awarded $2,500 for discovering a theoretical scenario where a party could empty the smart contract's balance of 1 TON by sending a large number of internal messages. Though it lacked practical application, as the attacker had to spend an order of magnitude more TON than the targeted address had on its balance.

• Gifted Lemur is awarded $1,000 for a bug they discovered (a fix for outbid messages that may contain incorrect data).

• Slim Elk is awarded $500 for finding an issue in a deprecated function.

• Fairy Horse and Sharp Butterfly are awarded $250 each for their minor optimizations and adjustments.

Congratulations to the winners!

P.S. We will soon contact each winner to coordinate their payouts. To check your animal alias, kindly log in on contest.com using the account from your submission.

🏆 Telegram X Android Competition, Round 2: Results

In this round, there were 11 contestants who contributed to 3 separate features for Telegram X:

Channel Comments + Message Threads – 4 submissions
The ‘Send As’ feature – 5 submissions
Improved Search – 4 submissions

While we strongly advised focusing on a single feature to achieve the highest level of quality, several competitors did try 2 or even all 3. We were pleasantly suprised by the skills of Dreamy Crab, who succeeded in implementing 2 well-polished features.

As stated in the announcement, there is only a single nomination per feature – each of the contestants listed below will shortly receive a 70% payout. For the next 2 weeks they can continue improving their apps and fixing any bugs with the help of the Telegram X community once they arrive on the beta. After that, they will receive the remaining 30% of their prize.

While testing the submissions and evaluating the entries' code, we focused on the following criteria: code consistency, overall app stability and how precisely the the provided design was followed.

Here are the winners:

⭐️ Dreamy Crab – $7,700 (70% of $7,000 + $4,000)
• The ‘Send As’ feature
• Improved Search
(The remaining $3,300 will be paid after the community testing phase.) This entry will be available soon on @tgx_log.

⭐️ Subtle Piranha – $6,300 (70% of $9,000)
• Channel Comments + Message Threads
(The remaining $2,700 will be paid after the community testing phase.) This entry can be tested from @tgx_log – and your bug reports are welcome in @tgandroidtests.

The judges unanimously noted 2 other entries – we would like to award ✨Modest Dolphin a bonus prize of $1,000 for a solid attempt at implementing the ‘Send As’ feature. ✨Busy Raсcoon also earns $1,000 for their implementation of Channel Comments – they added a beautiful animation for previewing comments.

All are welcome to check the reviews for each submission, now available on contest.com

Congratulations to the winners and stay tuned for more Telegram X Competitions.

🏆 Telegram iOS Contest 2022, Round 1: Results

We were pleased to see 68 developers, both newcomers and accomplished contest veterans, participate in this competition to implement a feature-rich media editor from scratch.

For such a complex task with a tough deadline, many contestants delivered solid apps. However, no submissions in this round qualified for🥇1st place. For this reason, we will be giving smaller rewards to a larger than usual number of apps. Congratulations to the winners – the number of people on today’s podium indicates a growing community of skilled programmers.

Remember, winning Telegram Contests is the only way to join the Telegram Team.

When evaluating the entries, we first rated how well an app implemented the minimum requirements, then separately reviewed any of its extra features. Smooth, high-quality drawing was the top priority.

🏆 Telegram UI Competition for iOS: Results

Out of the 27 total submissions, 23 implemented at least one animation flow – and 21 entries have earned rewards.

The new archive animations proved particularly challenging for all contestants – as no one was able to implement the provided design flow for every possible state of the chat list.

However, Hip Mantis deserves special recognition for their excellent implementation of the chat preview flow. For the strongest submission, Hip Mantis receives 🥇 1st PLACE – also noting their solid attempt at the archive animation and years of contest participation.

Please meet the winners:

🥉 Fierce Goat
🥉 Perfect Wasp

🎨 Android Design Contest

Prize fund: $30,000
Deadline: 23:59 on October 5th (Dubai time)
Who can participate: Everyone
Results: October 19th, 2023

Telegram is hosting a new design contest for its Android app.

The Task:
Create a detailed redesign concept for the Telegram Android app. Your concept should maintain the app’s core essence and lightweight feel while introducing an improved visual aesthetic with updated elements.

The guidelines of Material Design 3 may also be used for additional reference. To be eligible for any rewards, your submission must include all the areas and components outlined below.

Minimum Requirements:

Chat List
• Bottom Navigation Bar

Chats
• Private Chats (including Secret Chats)
• Channels (both admin and subscriber perspectives)
• Groups (including those with topics enabled)

Profiles
• User Profiles
• Group and Channel Info pages

Settings
• Main Settings Page
• User Info

Your design should thoroughly consider various scenarios and encompass all related elements and components – such as pinned messages, service messages, shared media, stories and more.

For the Chat List you can include an optional version with a white header (and an alternate translucent appearance).

Submission Format:
1) The layouts can be implemented as static .png files. For any animation demos, use .mp4 format (without sound).
Source files and properly structured Figma projects are also welcome.
2) If you include 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.

Submissions that include detailed visualizations, such as videos showcasing your project from a general perspective and offering in-depth views of elements like transition flows between screens and interface animations (including buttons) are more likely to receive a higher place in the prize rankings.

@ContestBot will begin accepting submissions at a later date. We will further clarify the submission instructions closer to the deadline.
