Abstract: A blockchain tokenization involving minting tokens on one blockchain that are backed by cryptoassets on a different blockchain. A node processor stakes an amount of cryptoassets on a value blockchain by transferring the amount of cryptoassets from a staker address on the value blockchain to an address of a smart contract on the value blockchain. The node processor, responsive to the staking, mints an amount of utility tokens on the utility blockchain. The amount of minted utility tokens are stored on the utility blockchain mapped to the staker address. The amount of minted utility tokens are backed by the amount of staked cryptoassets on the value blockchain at a fixed conversion rate between the amount of cryptoassets staked on the value blockchain and the amount of minted utility tokens on the utility blockchain.

Abstract: Systems and methods for recovering access to a digital smart contract wallet stored on a blockchain. A new owner public-private key pair is created to replace a current owner public-private key pair for accessing the digital smart contract wallet. The digital smart contract wallet on the blockchain is updated to require a transaction signed by a new owner private key of the new owner public-private key pair for accessing the digital smart contract wallet. The digital smart contract wallet is updated using a recovery transaction signed by a recovery owner private key and a recovery controller private key to update the digital smart contract wallet on a blockchain to require signing transactions with the new owner private key. The recovery owner private key is part of a key pair with the recovery owner public key, and the recovery controller private key is part of a key pair with the recovery controller public key.
