Cobo MPC WaaS

Institutional-Grade Co-Managed Custodian Solution

What is MPC-TSS Based Technology

Cobo MPC WaaS leverages cutting-edge secure Multi-Party Computation (MPC) technology to implement a Threshold Signature Scheme (TSS).

Using MPC-TSS technology, private key shares are created simultaneously by each party in a secure environment.

These parties can then jointly sign transactions without ever exposing their key shares or materialising a private key at any time.

As the private key that executes transactions never exists or lives in any devices - rather, it is a collectively generated value, the MPC-TSS setup removes any single point of failure, making key theft, internal fraud and collusion more challenging for bad actors. This design ensures no one party can unilaterally move funds.

Cobo MPC WaaS Core Features

Create one or multiple MPC wallets with a few clicks

Multi-Role Collaboration

The establishment of multiple roles facilitates institutions to establish customisable workflows according to their needs, allowing them to work more efficiently, and support operation scaling. Creators will be able to create a segregation of duties by managing users and assigning permissions and roles.

Creator / Administrator

Manage users, assign permissions, configure risk control policies and settings, and manage API keys

Operator

Traders that can add, transfer, buy/sell, trade assets

Approvers

Ability to approve transactions initiated by the operators

Viewer

The default role after registering for an account. Viewers are unable to perform any operations on assets and will have read-only permissions, where they are able to view balances and transaction records

Allows the creation of multiple wallets for different businesses, while operators and auditors can be set up separately

Supports multi-role collaboration

Allows the assignment of the same role to multiple employees to avoid a single point of failure

Flexible Customisation of Strategies To Meet Personalised Risk Control Needs

Multiple customisable risk control strategies for the prevention of operational risks, to enhance the security of on-chain exchanges and ensure asset’s security.

1. Setting up a list of contract addresses to control the contract interaction rules

Set up a whitelist of contract addresses to restrict interaction with contract addresses that are not in the list
Set up a blacklist of contract addresses to restrict interaction with contract addresses in the list

P1
Cannot successfully interact with the contract address on the blacklist
P1
Wants to interact with contract addresses that are not on the whitelist and requires the consent of all 3 approvers to pass

2. Set the review rules for each transaction

Support multi-person review. For example: Set up 3 approvers, and require 2 of 3 approvers to agree to each transaction before any asset can be released

3. Set the review rules for transaction amounts

You can set a limit based on the transaction amount, and the granularity can be subdivided into per transaction/hourly/daily
Enables the user to review transactions with larger amounts

P3
A single transaction amount exceeding 10,000 USD requires the consent of 2 of the 3 approvers to pass
P4
Each transaction requires the consent of 1 of the 3 approvers before it can be approved
