Abstract: An exemplary method includes generating, by a trust computer system, script instructions to carry out a transaction involving one or more digital wallets held in a trust custody account so as to verify control of digital assets held in the one or more digital wallets, the trust computer system being operatively connected to a decentralized digital asset network that uses a decentralized electronic ledger in the form of a blockchain maintained by a plurality of computer systems to track asset ownership and/or transactions in a digital asset system, and generating script instructions includes accessing a statement associated with an event that occurred within a predetermined time frame, and generating, by the trust computer system, based on the script instructions, a transaction that involves a zero net payment from the account along with the statement, and payment of a transaction fee from a separate operating account.
