Keep in mind that if you are withdrawing received funds, you'll also want to be careful about what address you withdraw to in order to maintain your privacy. With regard to receiving funds, note that it can take a while for the scanning process to complete, and this is an open problem Umbra is working to improve. Once identified, you can withdraw the funds to a safe address. □ Receiving funds - If you're on the receiving end, you can use the Receive page to scan for incoming transactions.There is a minimum send amount so the intermediary stealth address can safely cover gas costs. Choose the amount and the token you want to send, e.g., ETH, and then confirm the transaction. □ Sending funds - Use the Send page to enter the recipient's ENS name or address.This step is not necessary but great for security as it ensures Umbra never accesses your main wallet's private key. □ Set up an account - Use the Setup page to sign a message + transaction to generate Umbra-specific public and private keys.□ Visit Umbra - Head to the Umbra app, connect your wallet, and switch to your network of choice (Ethereum, Arbitrum, Gnosis, Optimism, and Polygon currently supported).□ Prep your wallet - Have a wallet (e.g., Coinbase Wallet, MetaMask, Rainbow) with some ETH or tokens ready to send.Pretty neat, right? Well, if you're interested in taking Umbra for a spin yourself, the process is straightforward. This new stealth address is where the funds are sent, and only the recipient, with the correct private key, can access and withdraw these funds, ensuring privacy. Thus, when a payment is made, the sender generates a "stealth address" using a combination of their own and the recipient's public keys. The magic behind this system is made possible by elliptic curve cryptography. In other words, imagine giving someone a brand-new, never-before-used address every time they want to send you funds. In simple terms, this protocol allows users to send funds to a fresh address that only the sender and receiver are aware of, adding a layer of privacy to the transaction. via Umbraīuilt by the Scopelift team, Umbra is what's known as a "stealth address" protocol designed for Ethereum and Ethereum Virtual Machine (EVM) networks like L2s.
