# Platform Offering

### Dedicated Client Vaults

DCVs are institutional-grade, per-client on-chain vaults on Ethereum mainnet. Each client mandate is executed in a dedicated vault contract with no pooling or commingling of assets. The DCV service is delivered by **Tesseract Investment Oy** under its MiCA-authorised discretionary portfolio management mandate.

DCVs are suited to custodians, institutional investors, exchanges, and any counterparty seeking regulated, transparent, segregated yield generation on crypto-assets.

**Integration models:**

* **Tesseract app** — end clients access their vaults via [app.tesseract.fi](https://app.tesseract.fi) using WalletConnect (retail) or Narval (institutional).
* **Direct smart-contract integration** — partners interact with the vault contracts and the [Public API](https://api.vault.tesseract.fi/public/docs) from their own infrastructure. See the [DCV Integration Guide](/dedicated-client-vaults/integration-guide.md).

### Earn API

Earn API empowers businesses to offer crypto yield opportunities to their users without the burden of backend infrastructure. With seamless integration and built-in wallet, security, and compliance features, it enables platforms — such as exchanges and fintechs — to focus on user experience while maintaining control over identity verification.

It's ideal for companies entering the crypto yield space that want to provide a smooth and customizable experience.

**Earn API is the solution for you if:**

* You operate a platform and want to seamlessly integrate Earn functionality while maintaining an excellent user experience
* You are a regulated entity and manage your own KYC processes
* You have a capable tech team ready to handle the technical integration

**Estimated integration time:** 14–21 days

### Earn Direct

Earn Direct allows Tesseract to serve end-users directly, with Tesseract Investment Oy handling the entire KYC / AML and onboarding process. This model is suited to partners who prefer to refer their clients to a regulated provider rather than operate the regulatory infrastructure in-house, and to companies seeking regulated yield services on their treasury holdings.

**Tesseract Investment Oy** — MiCA-authorised and FIN-FSA-supervised as a Crypto Asset Service Provider — performs the KYC/AML, custody, and asset transfer functions. Users can connect their wallets through WalletConnect and deposit directly via our WebApp.

**Note on custody architecture.** Earn Direct and DCV use different custody architectures. Earn Direct uses MiCA-authorised custody through Fireblocks MPC. DCV is non-custodial; the client's assets reside in their own dedicated vault contract.

**Earn Direct is the right integration model if:**

* You are a partner that does not hold the relevant regulatory authorisations in your jurisdiction, and you want to offer yield services to your clients by partnering with a regulated provider. Tesseract Investment Oy provides the regulated compliance and custody layer; you remain responsible for your own regulatory obligations, including any licensing, suitability and consumer-protection requirements applicable to you.
* You lack the technical resources to implement a direct Earn API integration.

**Estimated integration time:** 7 days
