Yesterday we received an official notification from NEO that there were some security problems on the NEP-5 based contract assets.

The tech team have already tested the deployed BCS smart contract on Testnet. They found that BCS does not have any of the security problems mentioned above.
Read4Sec audit company has examined the code and they have concluded that BCS smart contract is safe.
We would like to thank NEO official for his conscientious handling of our case and for providing NEO platform, which is a solid environment for developing decentralized apps.
Thank you for your long attention to BCS, and thank you for NEO’s official support.
