💎 Smart Contract Cracking Competition

Prize fund: Up to $100,000
Deadline: 18:00 on October 25th (Dubai time)
Who can participate: Everyone

The Task is to identify potential vulnerabilities and issues in the smart contract that would form the basis of the Auction Platform.

Evaluation Criteria and Prize Fund Distribution:
Bounties are dependent on the severity of the discovered issues and could potentially range from $200 for minor code adjustments to $50,000 for major flaws – like behavior that could bypass the smart contract's logic and conditions in order to reassign ownership of assets.

Details:
For a complete description and technical details, see this document.

Submissions:
1. Submit an archive containing your source code, a how-to manual, and a build script (if necessary) to @ContestBot (choose Smart Contract Cracking Competition).

Or:

2. Submit a pull request on GitHub. Describe the issue as a comment to the pull request. Submit a link to the pull request via @ContestBot .

🏆 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.

Prize fund: $100,000 ($50,000 for each platform)
Deadline: 23:59 on March 4th (Dubai time)
Who can participate: Everyone
Results: March 18th, 2023

The Task is to implement the redesigned flow for audio and video calls into Telegram for Android OR Telegram for iOS based on the provided mockups (Android / iOS). Regardless of the platform you chose, the submission must precisely represent the provided design – this includes all elements, their proportions and position on the screen, as well as their animations and transitions.

Details:
For a complete description of the required features and logic together with contest guidelines, see these documents:
• Android
• iOS

Evaluation Criteria:
During the evaluation stage, Telegram judges will test the submissions on a broad range of Android and iOS devices. The key factors that will be used to determine the best apps are:

- The general aesthetics of the app.
- Adherence to the provided mockups and design elements.
- Attention to the tiniest details in the user experience.

The smoothness of animations and the overall stability of the app will play a major role. Last but not least is the absence of significant flaws (including crashes, performance issues, battery drains, visual glitches, noticeable element blinking, layout imperfections and more).

Winners on each platform may be offered a chance to join the Telegram team in Dubai.

Submissions:
Contestants will be able to submit their entries to @ContestBot at the end of this round. We will further clarify the submission instructions closer to the deadline.
