Forever Money

1. Introduction

Creator Bid engaged Halborn to perform a security assessment of their smart contracts from December 22nd, 2025 to December 31st, 2025. The assessment scope was limited to the smart contracts provided to Halborn. Commit hashes and additional details are available in the Scope section of this report.

The Creator Bid codebase in scope consists of smart contracts for creating ERC20-based Agent Key tokens, including single-sided liquidity pools, prediction markets, reward distribution, and a time-weighted BID locking NFT system with credit management.

2. Assessment Summary

Halborn was allocated 8 days for this engagement and assigned 1 full-time security engineer to conduct a comprehensive review of the smart contracts within scope. The engineer is an expert in blockchain and smart contract security, with advanced skills in penetration testing and smart contract exploitation, as well as extensive knowledge of multiple blockchain protocols.

The objectives of this assessment are to:

• Identify potential security vulnerabilities within the smart contracts.

• Verify that the smart contract functionality operates as intended.

In summary, Halborn identified several areas for improvement to reduce the likelihood and impact of security risks, which were partially addressed by the Creator Bid team. The main recommendations are:

• To implement a slippage limiter in the exactInOnPool function.

• Removing _tokenIds inside the burn function.

• To manage the claim rewards from in the unstaking function explicitly before withdrawing a position.
