3. What are the Services offered?

Our services (“Services”) primarily consist of enabling users to create their multisig accounts in Hypercore and ongoing interaction with it on the Blockchain.

  1. “Hypercore multisig account”

A multisig account (Hypersig account) is a modular, self-custodial (i.e. not supervised by us) Hypercore consensus-based wallet not provided, maintained, developed, or controlled by Keyper Labs AG. Keyper Labs AG did not create these immutable mechanisms, and you are leveraging those contracts with no guarantees, and Keyper Labs has no control over them. We offer no guarantees over the general security, completeness, or correctness of the contracts or any information that we provide through any service.

Hypercore consensus-based multisig wallet means, unlike a standard private key Wallet, that access control for authorizing any Transaction is defined in code. An example are multi-signature wallets which require that any Transaction must be signed by a minimum number of signing wallets whereby the specifics of the requirements to authorize a Transaction can be configured in code.

Owners need to connect a signing wallet with a Hypercore multisig account (Hypersig multisig account). Hypersig multisig account are compatible inter alia with standard private key Wallets such as hardware wallets, browser extension wallets and mobile wallets that support WalletConnect.

  1. “Hypersig App”

You may access Hypercore multisig accounts using the Hypersig web app at your own risk. The Hypersig App may be used to manage your personal digital assets on Hypercore. The Hypersig App provides certain features that may be amended from time to time.

4. What do the Services not consist of?

Our Services do not consist of:
