Abstract

Protecting digital assets is disclosed. A primary digital asset associated with a shadow asset are stored, in a first and a second digital wallet. The primary digital asset and the shadow asset are each associated with respective smart contracts. When the primary smart contract executes, the second smart contract also executes. These smart contracts convert the shadow asset to be the primary digital asset and invalidate the original digital asset. This allows smart contracts to effectively protect a digital asset using digital wallets associated with different private keys and without having to actually transfer the digital asset. The activation of the shadow asset and invalidation of the original primary digital asset can be effected without a private key. The smart contracts execute when the conditions are satisfied.
