Creating equitable access to the global financial system
# Stellar Anchor Platform
The Anchor Platform is the easiest and fastest way to deploy
a [SEP-compatible](https://github.com/stellar/stellar-protocol/tree/master/ecosystem) anchor service.
It implements the majority of standardized API (`SEP`) endpoints that wallets, exchanges, and other applications use,
and provides a set of backend HTTPS APIs & callbacks for the anchor to integrate with for specifying fees, exchange
rates, and off-chain transaction status updates.
The goal of the Anchor Platform is to abstract all Stellar-specific functionality and requirements for running an
anchor, allowing businesses to focus on the core business logic necessary to provide these services.
## Getting Started
To get started, visit the [Anchor Platform documentation](https://developers.stellar.org/docs/category/anchor-platform).
Release notes can be found on the
project's [releases page](https://github.com/stellar/anchor-platform/releases).
## Contributing
Please refer to our [How to contribute](/docs/01%20-%20Contributing/README.md) guide for more information on how to
contribute to this project.
## Directory Layout
- __docs__: Contains the documentation for the Anchor Platform.
- __api_schema__: Contains the Java classes and interfaces that represent the API schema.
- __core__: Contains the core Anchor Platform implementation. Most of the SEP business logics are implemented here. No
infrastructures, such as database, configuration, queue, or logging implementations are assumed in this sub-project.
- __platform__: Contains the Anchor Platform implementation that uses Spring Boot as the underlying framework. This
sub-project is responsible for providing the infrastructure implementations, such as database, configuration, queue,
and logging. The `sep-server`, `platform-server`, `custody-server`, `event-processor` and `stellar-observer` services
are also implemented here.
- __kotlin_reference_server__: Contains the anchor's reference server implementation in Kotlin.
- __wallet_reference_server__: Contains the wallet's reference server implementation in Kotlin.
- __service_runner__: Contains the service runner implementation that runs services, such as SEP, platform, payment
observer, and reference servers, etc. It also contains the main entry point of the Anchor Platform.
- __essential-tests__: Contains the essential integration tests and end-2-end tests for the Anchor Platform.
- __extended-tests__: Contains the extended integration tests and end-2-end tests for the Anchor Platform.
## Quickstart
Anchor Platform can be run locally using Docker Compose.
### For version 2.x.x stable release
```shell
# In the root directory of the project
docker compose --profile v2-stable up -d
```
### For latest release
```shell
# In the root directory of the project
docker compose --profile latest up -d
```
### For locally built image
To build the Anchor Platform image locally, run the following command in the root directory of the project.
```shell
# In the root directory of the project
docker build -t stellar/anchor-platform:local .
```
Then, run the following command to start the Anchor Platform.
```shell
# In the root directory of the project
docker compose --profile local up -d
```
The [Stellar Demo Wallet](https://demo-wallet.stellar.org) can be used to interact with the Anchor Platform. To get
started, create and fund a new account, then add a new asset with the following parameters.
| Parameter | Value |
|--------------------|------------------------------------------------------------|
| Asset Code | `USDC` |
| Anchor Home Domain | `localhost:8080` |
| Issuer Public Key | `GDQOE23CFSUMSVQK4Y5JHPPYK73VYCNHZHA7ENKCV37P6SUEO6XQBKPP` |
Now you can deposit and withdraw USDC using the Stellar Demo Wallet.
