  title: Cobo Wallet as a Service 2.0
  description: >
    The Cobo Wallet-as-a-Service (WaaS) 2.0 API is the latest version of Cobo's
    WaaS API offering. It enables you to access Cobo's full suite of crypto
    wallet technologies with powerful and flexible access controls. By
    encapsulating complex security protocols and streamlining blockchain
    interactions, this API allows you to concentrate on your core business
    activities without worrying about the safety of your assets. The WaaS 2.0
    API presents the following key features:

    types](https://manuals.cobo.com/en/portal/introduction#an-all-in-one-wallet-platform)

    - Support for 80+ chains and 3000+ tokens

    - A comprehensive selection of webhook events

    - Flexible usage models for MPC Wallets, including [Organization-Controlled
    Wallets](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/introduction)
    and [User-Controlled
    Wallets](https://manuals.cobo.com/en/portal/mpc-wallets/ucw/introduction)

    - Programmatic control of smart contract wallets such as Safe{Wallet} with
    fine-grained access controls

    - Seamlessly transfer funds across multiple exchanges, including Binance,
    OKX, Bybit, Deribit, and more

        Group](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/create-key-share-groups)
        after you've created the Main Group with [Create key share holder
        group](https://www.cobo.com/developers/v2/api-references/wallets--mpc-wallets/create-key-share-holder-group).
        You only need to do this once per
        [organization](https://manuals.cobo.com/en/portal/organization/introduction).


        - `KeyGenFromKeyGroup`: This is a request to use the [Main
        Group](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/create-key-share-groups)
        to create key shares for your [Signing
        Group](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/create-key-share-groups)

        share holder
        group](https://www.cobo.com/developers/v2/api-references/wallets--mpc-wallets/create-key-share-holder-group).

        Group](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/create-key-share-groups)
        for a key share holder in the [Main
        Group](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/create-key-share-groups)

      description: >
        The TSS request status. Possible values include:

        - `PendingKeyHolderConfirmation`: The action done to the TSS request is
        currently pending enough key share holders to approve.


        - `KeyHolderConfirmationFailed`: Key share holders failed to approve the
        the action to be done to the TSS request.


        - `KeyGenerating`: The key share is currently being generated for the
        action to be done to the TSS request.


        - `MPCProcessing`: The TSS request approval is waiting to be started. 
          - For [MPC Wallets (User-Controlled Wallets)](https://manuals.cobo.com/en/portal/mpc-wallets/ucw/introduction), you need to use the Client App and call the UCW SDK to start the TSS request approval process.
          - For [MPC Wallets (Organization-Controlled Wallets)](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/introduction):
            - If you are using the [server co-signer](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/create-key-share-groups#create-a-main-group), this status indicates that the TSS Node will soon request the callback server to start the [risk controls](https://manuals.cobo.com/en/portal/risk-controls/introduction) check. No further action is required from you at this stage.
            - If you are using the [mobile co-signer](https://manuals.cobo.com/en/portal/mpc-wallets/ocw/create-key-share-groups#create-a-main-group), key share holders need to use their [Cobo Guard](https://manuals.cobo.com/en/guard/introduction) to approve the TSS request and participate in the signing process.

        - `KeyGeneratingFailed`: The key share generation process has failed for
        the action to be done to the TSS request.


        - `Success`: The action done to the TSS request has been completed
        successfully. If you see this status while running [Cancel TSS
        request](https://www.cobo.com/developers/v2/api-references/wallets--mpc-wallets/cancel-tss-request),
        this mean the specified TSS request has been successfully canceled.
