Abstract: A method includes receiving, from a source user account associated with a source digital wallet of a source blockchain, a request to perform a cross-chain operation from the source blockchain to a destination blockchain. The source blockchain is associated with a source token contract that stores a delta value indicative of a difference between a total number of tokens having an attribution property in circulation of the source blockchain and a number of tokens having the attribution property in circulation of the source blockchain that are accounted for by a vault of a primary blockchain. The attribution property identifies a token issuer. The method further includes causing a cross-chain message including a transaction payload to be generated based at least in part on the delta value, and causing the transaction payload to be applied to the destination blockchain.

Abstract: A method includes receiving a transfer request defining a transfer amount of tokens to be transferred from a sender associated with a first digital wallet to a receiver associated with a second digital wallet. The sender has a total token balance including an attributed token balance and a float token balance of float tokens, the attribution token balance and the float token balance are maintained within a token contract, and the receiver is assigned with a designated attribution property. The method further includes causing a transfer function of the token contract to be executed to transfer a set of tokens from the sender to the receiver. The set of tokens is determined based on a transaction payload comprising at least one of: a number of attributed tokens debited from the attributed token balance or a number of float tokens debited from the float token balance.
