Contest Proposal: GrandBazaar Auctions Smart Contract Code Audit
Short Description
The contestants shall provide the informal audit of the central Grand Bazaar smart contracts (Offer and Auction), hereinafter referred to as “smart contracts”, where the detailed description of the “Code audit” is described below. All debot contracts are excluded from the present contest.
Motivation
Ideally speaking, all smart contracts issued by the Free TON ecosystem must pass the formal verification process. However, as the formal verification is an extremely time-consuming process, in some cases the business cannot wait for such a long time. Additionally, each bug found during the formal verification requires a major rework of the whole underlying stuff already completed.
To address both above-mentioned issues, we suggest undertaking the Code audit before proceeding to formal verification. Being capable to find most bugs, the completion of this kind of activity allows us to:
- Release a smart contract with a high (but not the highest) level of reliability (this should be undertaken exclusively in a case of a strong business need)
- Dramatically decrease the likelihood of finding a bug during the formal verification (taking into account that each bug found at the formal verification stage brings major overhead for the proving system)
Prerequisites
Before entering the informal audit process, each smart contract must comply with the following rules:
- The smart contract must be compilable with the latest version of tondev tool
- All smart contracts must be submitted with detailed documentation
- The smart contract’s developers must set up a Telegram group for discussions as well as a slot for one-hour voice meetings at least once a week
- All the smart contracts being audited must be covered by unit and integration tests
- All the tests must pass
Location
The source code is available at GitHub - grandbazar-io/True-NFT at branch master with hash code equal to b887198ded91f930f6e16191a0be2bf3764f01ae.
Contest Terms
Contestants shall submit a document in PDF format that covers:
● All the errors found
● All the warnings found
● All the “bad code” (long functions, violation of abstraction levels, poor readability etc.)
Foundings
Errors and warnings should be submitted to the developers as early as possible, during the
contest, so that the code can be fixed immediately.
The document should also contain a high-level description of the system, and any information
showing that the contest had a good understanding of the infrastructure and of the code.

- All the requirements mentioned above are considered as mandatory otherwise some points have to be taken from the corresponding application
- The usage of industry-adopted 3rd party tools should bring additional points in case the motivation of their usage has been clearly demonstrated
- Any team that managed to find a non-minor bug must be placed higher than a team that failed to do it
- Any bugs related to the kind of the exceptions as well those related to the logging or retrieving the state are considered as minor and should not be taken into account for the ranking

If such contact information is missing, the submission shall be rejected.
