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 using WalletConnect (retail) or Narval (institutional).
• Direct smart-contract integration — partners interact with the vault contracts and the Public API from their own infrastructure. See the DCV Integration Guide.

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
