What Exactly Does Locking a Card Do?
When a user locks a card, they set a number of days for the unlocking function. When a card is locked, it may not be sold, transferred, combined, or burned until it is unlocked. A locked card may be played in any of our play modes, delegated to another account, or rented on the market.
Why Should I Lock My Cards?
A user may want to lock their cards in an account as insurance if their private keys ever become compromised. A malicious actor who has compromised a user's keys to access their account would not be able to steal any of the cards if they are locked.
If the cards were not locked, the malicious actor could sell, burn, or combine them as soon as they gained access to an account. If the cards are locked, the malicious actor would have to start the card unlock process and wait for the cards to be unlocked before they would be able to sell, transfer, combine or burn the cards. Hopefully, the original owner, having set the unlock time to an appropriate timeframe, will see their cards being unlocked before they are available, cancel the unlocking of the cards and change their keys.
While locking a card, users must pick the number of days that they would like to set for the unlocking period, which will create this length of the delay before the card is available for transferring after having unlocked the card successfully, giving users time to attempt recovery of their account to retrieve any assets secured in this manner.
There are a few thoughts on the length of unlock time; they all depend on your situation. If you have cards that you plan to keep in an account for a long time, it might be most appropriate to put them on a 30-day cooldown. For other cards you may plan on selling or moving to another account soon, it might be more suitable for you to have a shorter unlock time; some users find seven days to be an excellent short-term unlock period. Each user should take the time to evaluate which unlock period makes the most sense for their investment style and their circumstances.
