This repository contains the *official Go SDK for Stellar*, maintained by the [Stellar Development Foundation].
It provides all the tools developers need to build applications that integrate with the Stellar network, including APIs for Horizon and Stellar RPC, as well as foundational utilities and ingestion libraries for working with raw ledger data.
This repo previously served as the [Go Monorepo](https://github.com/stellar/go) for all SDF Go projects. As of October 2025, it has been refactored to focus exclusively on developer-facing SDK packages. Services that are still maintained have been moved to their own dedicated repositories.
This repo follows [Go Module Versioning](https://go.dev/doc/modules/version-numbers).
## Usage
Run the following command inside your Go project.
```
go get github.com/stellar/go-stellar-sdk@latest
```
## Package Index
| Package | Description |

## Relocated
The following services have been moved to their own repositories and are no longer built from this SDK:
| Service | New Repository | Description |
|-----------|-----------|-----------|
| Horizon | [stellar-horizon](https://github.com/stellar/stellar-horizon) | Full-featured API server for querying Stellar network data |
| Galexie | [stellar-galexie](https://github.com/stellar/stellar-galexie) | Ledger exporter that writes network data to external data stores |
| Friendbot | [friendbot](https://github.com/stellar/friendbot) | Stellar's test network native asset faucet |
If you build or deploy these services from source, please use their new repositories. Pre-built Debian packages and Docker images continue to be distributed through the same channels.
