Evaluation Criteria

Each submission will be carefully analyzed and evaluated based on the following factors:

• Severity of the impact on the network. Denial of Service attacks are not considered valid in this case
• Viability of conducting such an attack
• Quality of the description of the issue
• You must be the first to report the specific vulnerability to be eligible
• Availability for follow-up questions with the core ICON team

Instructions

The first iteration of xCall utilizes Blockchain Transmission Protocol (BTP) under the hood to provide interoperability between different blockchain networks

One of the components of BTP is called the Message Verifier. This is the component for verifying that a cross-chain message is truthful

We encourage participants to deep-dive into the implementation of the Message Verifier to find cases where it may fail or be unreliable

Ultimately, this helps uncover any vulnerabilities, so we can optimize the model and refine the implementation for mainnet!
