Auto-Lookup > Ethereum > Ethereum Execute Smart Contract

Background and Setup

Prerequisites

AgilePoint NX OnDemand (public cloud), or AgilePoint NX PrivateCloud or AgilePoint NX OnPremises v8.0 or higher.

Good to Know

There is more than one path to configure a lookup. Make sure you use the document that shows the path for your lookup.
Some information about third-party integrations is outside the scope of the AgilePoint NX Product Documentation. It is the responsibility of the vendors who create and maintain these technologies to provide this information. This includes specific business use cases and examples; explanations for third-party concepts; details about the data models and input and output data formats for third-party technologies; and various types of IDs, URL patterns, connection string formats, or other technical information that is specific to the third-party technologies. For more information, refer to Where Can I Find Information and Examples for Third-Party Integrations?
