Publication number: 20240257084Abstract: A custodial token platform may implement a single smart contract for outbound messages. The custodial token platform may deploy, to a blockchain distributed data store, a self-executing program that batches messages from the self-executing program to multiple addresses of the blockchain distributed data store that are external to a custodial token platform associated with the self-executing program. The custodial token platform may select, from the multiple withdrawal requests and based on selection criteria, a set of withdrawal requests to fulfill via a batch message from the self-executing program. The custodial token platform may broadcast, to the blockchain distributed data store, a message that calls the self-executing program. The message includes an indication of a set of external addresses associated with the set of withdrawal requests, and the message causes a transfer of a set of crypto tokens from the self-executing program to the external addresses via the batch message.Type: ApplicationFiled: January 27, 2023Publication date: August 1, 2024Inventors: Peter Jihoon Kim, Brock Miller, Kai Luo, Jiangchuan He, Vignesh Muralidharan, Rajeev Vishaka
