Survey for TON developers 💫

Developers in the TON ecosystem may experience some problems reading the documentation because it is written in a complex language, often lacking examples or materials on essential parts of the TON blockchain.

The goal for the TON ecosystem is to create next-generation documentation accessible to everyone: both beginners and experienced developers.

To achieve it, we decided to collect feedback from the community. So we kindly ask all members of our community to share their experiences through the survey.

It consists of 10 questions and will take no more than 5 minutes.

Participate in the survey:

More details about TON Hack Challenge are here ✌️

Challenge starts on 23 Oct. at 09:00 UTC and lasts until 18:00 UTC. TON Hack Challenge is a one-day contest aimed at finding vulnerabilities in smart contracts written in FunC, the programming language native to The Open Network blockchain with a prize pool of 30,000 TON.

The task is to hack 8 smart contracts. Each of these contains a major flaw that allows intentional bypassing of intended logic and stealing of all funds. As soon as the participant figure out the issue they are encouraged to hack the smart contract and get all the Toncoin. The prize will be awarded to the participants, who successfully hack smart contracts, and paid in TON. As soon as the participant figure out the issue they are encouraged to hack the smart contract and transfer all Toncoin from the contract balance (the bounty) to their wallets.

👉 More information about the contest and additional rewards are provided on the website.

Here is the TON Hack Challenge checklist to prepare for the contest:
💎 Register through the @toncontests_bot.
💎 Read the official docs and set up a developer’s environment.
💎 Make sure you have a couple of TON — actually, 2 TON is enough for all tasks.
💎 Learn how to compose arbitrary cells via fift, tonweb, ton3, ton(whales), tongo, pytonlib.
💎 Learn how to compose internal messages and send messages to the network.
💎 Study how to read tl-b notation.

TON Hack Challenge which is dedicated to finding vulnerabilities in smart contracts has launched!

A full denoscription of tasks is available on GitHub, click here or go to the website.

To be able to participate you need to have a couple of TON, know how to compose arbitrary cells (via fift/tonweb/ton3/ton(whales)/tongo/pytonlib), compose internal messages and send messages to the network. It will be useful to know how to read tl-b notation.

Each contract contains a major flow that allows to bypass of intended logic and stole all funds.

There will two stages of the contest:
1. The first 5 contracts are revealed at the same time to hack. After all smart contracts of the first stage will be hacked, there will be a 15-minute break.
2. The last 3 contracts will be revealed one by one: once a contract is hacked, there will be a 15-minute break and the address and info of the next smart contract will be revealed.

For almost all contracts their funC code will be available on reveal. Some, however, will be closed-sourced: you will need to disassemble them via TonScan, Ton Whales, DTON.io, Ton.cx.

Please, note, if you want to be notified about hacking smart contracts from the task to save time, you need to register through @toncontests_bot.

❗️Dear participants, be careful with any spam from https://ton[.]events/airdrop — this is scam, that is not related to TON contests.

The first stage of TON Hack Challenge has been finished. 15,000 TON has found its hackers.

At 10:45 UTC the first contract from the second stage will be revealed on GitHub. Before continuing the TON Hack challenge, make sure you registered at @toncontests_bot to get information about the opening of the next contract and 15 minutes breaks.

We will publish solutions at the end of the contest. All the winners, please, note that you may receive a 150 TON bonus if you write explanations through the ‘Support’ button at @toncontests_bot after the contest.

The last smart contract of TON Hack Challenge has been hacked!

Many thanks to all the participants. TON Foundation hopes you enjoyed this contest 🤩

Congratulations to all the winners, don’t forget to share your thoughts while searching for solutions through the ‘Support’ button at @toncontests_bot. Step-by-step explanations will give you the chance to receive a 150 TON bonus. Also, we ask all participants to share their opinion about the contest through the feedback form that you will get from our official bot as well.

All the solutions are available on GitHub, reading them would help contestants to learn more about TON. We also plan to post all the denoscriptions of how winners hacked contracts, so everybody will learn both to search for bugs in smart contracts and to write more secure contracts.

TON Ecosystem needs white hat hackers, we highly encourage you to participate in the bug-revealing activity. Please, take a look at TON security bug bounty program.

There is also Telegram Smart Contract Cracking Competition for those participants, who wish to continue finding potential vulnerabilities in the smart contracts.

Nearly all the winner's solutions were uploaded to GitHub. Check them out. The winners will get their bonus reward soon 🤩

Also, each contestant of TON Hack Challenge will get a special NFT until the end of the week.

We are launching TON Smart Challenge #3!

This contest lasts until 23 Dec. 18:00 UTC and aimed at optimization of 5 smart contracts written in the FunC language native for The Open Network blockchain. The goal of the contest is to optimize contract execution cost, preserving functionality and business logic.

A full denoscription of tasks is available at GitHub. You may click here or go to the website.

Tasks are expected to be submitted through @toncontests_bot by clicking on the special button for sending solutions, and no more than five submissions per hour are allowed. Evaluations are performed after submission.

There will be two set of prizes for two stages of the contest:
💎 for sprinters during the first week (until 9 Dec 18:00 UTC) of the contest, according to the formula: Prize = A*(B+1/N)exp(-x(B+1/N)), where A = 25 000, B = 0.01, N — number of participants.
💎 for stayers — on the second and third week of TON Smart Challenge, according to the formula: Prize = A*(B+1/N)exp(-x(B+1/N)), the A = 25 000, B = 0.01, N = 100.

Note that stages are independent, contestants may win in both rounds. Good luck to everyone 🍀

Hello, contestants!

We need about 2-3 days to check and summarize the results of the first stage of the TON Smart Challenge #3. TON will be distributed until 19th December, but special NFTs only at the end of the second stage.

Please, note, all the cheaters from both stages will be disqualified. Cheaters are namely contestants that have submitted solutions from multiple accounts in order to increase their TON reward.

The second stage for stayers lasts until 23 Dec. 18:00 UTC. While diving into FunC, you may find helpful the dev portal.

Token Bridge Smart Contract Cracking Competition

Prize fund: Up to $50,000
Deadline: 18:00 UTC on December 30
Who can participate: Everyone

The Task is to identify potential vulnerabilities and issues in the FunC and Solidity smart contracts of Token Bridge.

Using this bridge, users can transfer any ERC-20 or BEP-20 tokens (for example, USDC or USDT) originally created on Ethereum or BNB Smart Chain to the TON Blockchain, with the ability to return them back.

The transferred tokens will be represented on TON as regular Jettons so that TON services, such as DEXs, will be able to work with them without any additional modifications.

Evaluation Criteria and Prize Fund Distribution:
Bounties are dependent on the severity of the discovered issues and could potentially range from $200 for bugs which do not affect economical safety to $25,000 for major flaws which can lead to Bridge insolvency or unconditional loss of assets by users. Prizes will be distributed in TONs.

Please focus on issues, conditions and attacks which could allow to bypass the smart contract's logic.

We are also interested in economic attack vectors to "ruin" oracles, given that oracles pay network fees.

Optimization of gas-usage or code-style improvements are out of the scope of this competition and will not be rewarded. Conditions when majority of validators or oracles (on any side of the bridge) are malicious or malfunctioning is out of the scope as well.

Details:

Denoscription »

Solidity smart contracts »

FunC smart contracts »

Testnet bridge »

You can find useful unit tests in both smart contract repositories.

Submissions:

Submit a pull request on GitHub to Solidity or FunC bridge repo. Describe the issue as a comment to the pull request. Specify your TON wallet address to receive a prize.

We are launching TON Thread Challenge 💫

The contest is for developers, community managers, content creators, and founders — those who work, learn, discover and build on TON with a $10,000 total prize fund. It starts today and lasts until 22 Feb 18:00 UTC.

The goal of the contest is to encourage TON ecosystem participants to share knowledge about TON and create unique and sharable content about The Open Network (as it will come from experts directly) available on Twitter.

The task is to create threads related to the TON blockchain, that follow several requirements:

💎 the thread should contain unique insights about TON
💎 the thread has to be in English and easy to read
💎 the thread should contain either fact value, education or entertainment, or all of that
💎 the thread should drive a conversation about building on TON, FunC, TVM, and white paper overview, mass adoption, community, NFT, the responsibility of building great apps message, decentralization, GameFi, SocialFi, DIDs and etc.
💎 the thread has to include min 3 onwards tweets

You are free to make funny threads, add memes, and stuff like that. Try to make it viral and get more engagement from the community.
