Abstract: Methods and systems use a dynamic gas range approach for facilitating blockchain operations across multiple blockchain networks using a decentralized exchange. Use of the multi-modal dynamic gas range process allows for the system to separate the data collection operation (e.g., analyzing data across many layers, features, front-end systems, back-end systems, libraries, and/or channels of multiple blockchain networks) and the dynamic gas range estimation operation. By doing so, the system first allows static blockchain operation characteristics to be verified, reducing uncertainty related to the cost of the blockchain operation (e.g., due to impermanent loss and continually changing network congestion). For example, the system may perform verifications and validations on data in a piecemeal manner such that errors and/or network conditions affecting the blockchain operation may be detected prior to the blockchain operation being confirmed.
