Abstract: Methods, systems, and devices for data management are described. A wallet service may include one or more application programming interface (API) endpoints. An API endpoint may receive a set of requests to broadcast messages via one or more blockchain networks, the set of requests including a first request to broadcast a first message via a first blockchain network and a second request to broadcast a second message via a second blockchain network. A first blockchain message may be generated using a mapping of a plurality of sets of network-specific parameters to respective blockchain networks, and the first blockchain message may include a first set of network-specific parameters. A second blockchain message may also be generated using the mapping, and the second blockchain message may include a second set of network-specific parameters. The first and second blockchain messages may be broadcast via respective nodes of the blockchain networks.

Abstract: Methods and systems are described for facilitating blockchain operations based on network congestion. The system may facilitate blockchain operations by generating recommendations for blockchain operations based on values for one or more blockchain operation characteristics that are determined based on a likelihood that a given blockchain operation will be completed in a timely manner. The system thus ensures accounts for transient congestion in a blockchain network, while also minimizing a burden on a user device attempting to perform a blockchain operation.
