# Process and Environments

Our goal is to give you all the support you need throughout the integration. This page sets expectations for what to expect during the integration process.

### Environments

| Environment | URL                                                                                                             | Description                                                                                                                                                                 |
| ----------- | --------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Development | [earn-api-dev.partner.env.tesseractinvestment.dev](https://earn-api-dev.partner.env.tesseractinvestment.dev/)   | Environment to develop against. All APIs are available but Tesseract does not settle its side of the outstanding balance.                                                   |
| Test        | [earn-api-test.partner.env.tesseractinvestment.dev](https://earn-api-test.partner.env.tesseractinvestment.dev/) | Copy of production where the partner can develop and test daily settlement with small amounts of real crypto (no test net support). Product list is a subset of production. |
| Production  | [earn-api.tesseractinvestment.com](https://earn-api.tesseractinvestment.com/)                                   | Live partner integration.                                                                                                                                                   |

### Process

#### Intro call

The purpose of the call is to get the project started on the right foot. Topics typically covered:

* Walk through the integration process and developer site contents.
* Address questions raised while reading the documentation.
* Agree on the communication channel between engineering teams.
* Agree on the practicalities of authentication credential delivery and exchange of settlement wallet addresses.
* Discuss integration timeline.

Prerequisite: a mutual NDA has been signed.

#### Authentication credentials delivery

Authentication credentials are delivered to partners using Bitwarden Send. Recipients should store credentials in a password manager or similar. Development credentials can be used from developer workstations; Test and Production credentials should only be used in cloud-based systems.

#### Exchange of settlement wallet addresses

Both parties need a wallet address per currency for outstanding-balance settlement in Test and Production. Tesseract sends Test environment addresses as soon as development has started. Tesseract can finalize Test configuration once the partner's wallet addresses are received.

#### Gate to production

Once all tasks in [Solution Architecture](/earn-direct-and-earn-api/earn-api/solution-architecture.md) are done, the partner should test in the Test environment. Tesseract can help verify reception of assets and check report contents. Once the partner believes testing is complete, Tesseract performs a final check before preparing access to Production.

Authentication credential delivery and wallet address exchange happen the same way as for Test.

Prerequisite for production access: an Alliance Agreement is signed.

#### Acceptance test

Acceptance tests are done in the Production system to verify a solid integration and correct configuration of the wallet addresses on both sides. See [Acceptance Testing](/earn-direct-and-earn-api/earn-api/acceptance-testing.md) for details.

#### Go-live

The service can be opened as soon as the acceptance test result is satisfactory for both parties.
