Copper Unlimited is a secure wallet for cryptocurrencies. It uses multi-party computation (MPC) cryptography to create and sign transactions without ever revealing a user’s private key. The Copper Unlimited app can only be used by copper.co customers who have completed all KYC (Know Your Customer) and AML (Anti-Money Laundering) checks. The app is designed to be used by institutions, sophisticated investors, asset managers, and professional traders only. If you’re interested in using the app, and do not already have a copper.co account, please contact our sales team who can speak to you about the requirements. Copper Unlimited supports an ever expanding universe of cryptoassets, including Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), Tether (USDT), plus over 100 more. Copper chose MPC technology because the key that executes the transaction is a collectively generated value. That means a single key never exists in whole, or lives on any device (including your app!). This renders an attack in key theft effectively impossible while also sheltering from internal fraud and collusion – preventing any employee, or group of employees, from misusing the key. Copper Unlimited is the fastest and most secure way to process withdrawals from Copper’s offline vault infrastructure.
