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!

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