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.

💎 Study how to read tl-b notation.
TON Hack Challenge which is dedicated to finding vulnerabilities in smart contracts has launched!

A full description 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.
