Abstract

Disclosed herein are methods, devices, and apparatuses, including computer programs stored on computer-readable media, for executing a cross-chain anonymous multi-swap (AMS) contract. One of the methods includes: detecting a recordation of a first plurality of parameters for the AMS contract on a first blockchain; recording a second plurality of parameters for the AMS contract on a second blockchain; detecting an invocation of a request to execute the AMS contract on the second blockchain; retrieving, from the request to execute the AMS contract on the second blockchain, a retrieved key used to unlock the second function lock on the second blockchain; calculating, based on the retrieved key, a calculated key for unlocking the first function lock on the first blockchain; and invoking a request to execute the AMS contract on the first blockchain with the calculated key.
