# Environments

> Where the Starke API runs, and what is planned for testing.

## Today: one environment

| | |
| - | - |
| API | `https://api.starke.finance` |
| Chain | Solana mainnet |
| Funds | the funds of Starke's public beta |
| Access | public reads, no API key |
| App | [app.starke.finance](https://app.starke.finance) |

Every call in this documentation goes to this environment. Its reads are safe to run: they change nothing.

The beta funds are offered only within the public beta program, for protocol testing and feedback, and are not an investment product. Their data is real on-chain data on Solana mainnet.

## Planned: a sandbox for integrators

A test environment is planned, so you can try every operation, writes included, without real funds:

* test assets, and test identities for the identity check;
* API keys, with higher limits than anonymous callers;
* the API reference's playground pointed at it.

This is a design, not available yet. This page will say when it is, and the [changelog](https://docs.starke.finance/api-reference/changelog.md) will announce it.

## Fund addresses can change

A fund's address belongs to the program version it runs on. When Starke moves its funds to a new version of its program, their addresses change and this page says so. Read addresses from the Starke app rather than writing them into your code.
