Audit Report

Smart Contract Audit Report 1. Summary

This report presents the results of our audit for the set of eight Solidity smart contracts. Each contract has undergone a detailed review, addressing previously identified issues. The contracts encompass a range of functionalities, including token management, claiming, vesting, and more.

2. Audit Details 2.1 Scope of the Audit

The audit scope covered the analysis of eight Solidity smart contracts, namely:

• claiming.sol

• paired.sol

• soulbound.sol

• ticket.sol

• vesting.sol

• pairedworldrdf.sol

• spoproxy.sol

• ticketaward.sol

The audit aimed to ensure the contracts' adherence to best practices, identification of security vulnerabilities, and verification of the resolution of previously reported issues.

2.2 Methodology

The audit employed a combination of manual code review and automated security analysis tools. Our focus areas included:

• Conformance to relevant standards (e.g., ERC-20, ERC-1155, OpenZeppelin contracts).

• Secure implementation of access control mechanisms.

• Accurate and secure arithmetic operations.

• Proper handling of external interactions and Merkle proofs.

• Protection against common vulnerabilities, including reentrancy attacks and unchecked return values.

• Verification of adherence to Solidity best practices.

2.3 Assumptions

It was assumed that third-party libraries and contracts, such as those from OpenZeppelin, were correctly implemented and secure, as they were not within the scope of the audit.

3. Findings

All previously identified issues have been meticulously addressed in the updated versions of the contracts. The review encompassed the following points for each contract:

• Access control mechanisms, ensuring proper ownership and permissions.

• Token minting and burning functions with correct validations.

• Implementation of Merkle proofs and their accurate usage.

• Integration of external interfaces and interaction with other contracts.

• Robust calculation and allocation mechanisms.

4. Conclusion

The eight smart contracts have successfully undergone audit and have resolved all identified issues. These contracts demonstrate adherence to their intended functionalities, industry standards, and security best practices.

While the audit has considerably mitigated potential risks, it is recommended to periodically review and audit the contracts, particularly if changes are made or significant value is involved. Additionally, it is important to acknowledge that audits reduce risks but do not eliminate them entirely.
