Unit price  per 

This is a pack of two SafeCards that have already been provisioned using an unknown PIN.  This means that these cards are UNUSABLE.  Do not purchase unless you are a security researcher interested in trying to pen test the security mechanism of the SafeCards!  These cards have a seed which contains 5 ETH which will not be moved by GridPlus until at least 12/31/2022. If a security researcher demonstrates an exploit which allows them to move the 5 ETH from the card, there is another 5 ETH bounty for creating and submitting a responsible disclosure showing how the exploit was carried out and is able to be reproduced and verified.  Therefore, there is a a total of a 10 ETH bounty for compromising one of the security challenge cards!  Checkout the card balance at: https://etherscan.io/address/0xba99444d4660f7b637c164f97a00ebcbd8ffe266 

All purchases of the security challenge cards are final, non-refundable and non-returnable.
