Forta Contest (12/17/2021)

Forta is thrilled to announce the last bot development contest of 2021!

Submit your entries for this contest HERE.

Forta bots are code scripts written in Python, Javascript and Typescript that trigger alerts when certain conditions are met. The best bots trigger alerts when specific conditions indicate that a potential hack or exploit may be taking place and help end users prevent them. For more information on creating your first bot, check out our quickstart guide and video tutorials.

Forta bot developer contests are mini-hackathons where anyone is able to submit a bot and be rewarded in NFTs, and Crypto!

Contest discussion group and announcements are available on our Discord.

Rules

  • You will find two challenges listed below. Each challenge has a specific security concern that a Forta bot monitors for. Please submit your completed bots to the contest judges through the Google form linked above and on connect.forta.network.

  • Only the first twenty five (25) QUALIFIED submissions to each challenge that meet the challenge requirements below will be considered.

  • After twenty five qualified submissions are received for a challenge, we will close the challenge and announce it in the #agent-dev-contests channel in Discord. As long as submissions are open, you are welcome to build and submit bots for both challenges!

  • All developers that submit a qualifying bot will receive a Forta NFT.

  • Cash prizes will be awarded to the 1st, 2nd, and 3rd place bots in each challenge.

    • 1st place will receive $1,500 in USDC and a unique Forta NFT.
    • 2nd place will receive $750 in USDC and a unique Forta NFT.
    • 3rd place will receive $250 in USDC and a unique Forta NFT.
  • To be eligible for a prize, you will be asked to submit a valid email and Discord username through the Google form, along with your bot.

  • This contest will run from December 17th through December 31st, after which no further submissions will be considered. Winners will be chosen by a panel of bot reviewers from Forta community member Arbitrary Execution, and will be announced on January 7th.

For any questions, please contact a Forta Moderator on Discord.

    • Does the code contain comments?
    • Is the code well-formatted and easy to read?
  • Testing

    • Do all tests run and pass?
    • Are there negative test cases? i.e. when alerts should not be created
    • Are there positive test cases? i.e. when alerts should be created
  • Documentation

    • Does the README.md have a concise description of bot functionality?
    • Does the README.md contain well-formatted descriptions of each alert?

Challenges

  1. Influencing Governance Proposals

    Governance proposals allow protocols to change to meet the evolving requirements of the DeFi ecosystem. Voting on these proposals occurs over a limited period of time where only those accounts that have been delegated votes may cast those votes in favor of or against the proposal. There is also a check to determine whether the delegated votes existed in the block number when the proposal was submitted.

    This challenge is to create a bot that will monitor proposals to the Uniswap Governance and the votes cast on those proposals. A finding should be created if an address casting a vote had a significant change in UNI balance in the 100 blocks leading up to the proposal starting block number.

    Optional, but recommended: Tracking balances in the 100 blocks after the vote is cast and creating a finding if the balance decreases.

  2. Evidence of Phishing

    Users approving token transfers to an externally owned address (EOA) may be a behavior indicative of a phishing attack.

    This challenge is to create a bot that will detect when a high number (e.g. 10 or more) of EOAs call the approve() or increaseAllowance() methods for the same target EOA over an extend period of time (e.g. 6 hours ~ 1600 blocks). The finding should include the affected addresses, the alleged attacker's address, and the addresses and amounts of tokens involved. Be certain to filter out smart contracts (i.e. approve() called by a smart contract or a smart contract that is the designated spender for an approve() call) and EOAs for any centralized exchanges (e.g. FTX exchange: 0x2FAF487A4414Fe77e2327F0bf4AE2a264a776AD2).

    The bot should trigger when run against the following block range: 13650638 to 13652198
