This document outlines the security policies for the Block Fund Crowdfunding Platform, a blockchain-based crowdfunding application. We take the security of our platform very seriously and appreciate the community’s assistance in identifying and mitigating potential vulnerabilities.

We actively support the following versions of the platform. We recommend that all users and developers use the latest version to benefit from the latest security updates:
