Documentation

Overview

Package horizon is DEPRECATED in favour of clients/horizonclient! It used to provide client access to a horizon server, allowing an application to post transactions and lookup ledger information.

Deprecated: clients/horizon package with all its exported methods and variables will no longer be maintained. It will be removed in future versions of the SDK. Use clients/horizonclient (https://godoc.org/github.com/stellar/go/clients/horizonclient) instead.
