Practical notes on choosing and managing a wallet.
Expand the articles without leaving this page.
Assets are recorded on the blockchain. Wallets manage the keys used to sign. A dedicated device helps isolate keys, but you must still verify the address, network and amount. Recovery depends on your backup; anyone with it may control the assets.
Define who initiates, who reviews and which amounts require additional approval. Plan role handovers, recovery and activity records. For multisig or MPC products, verify the signing mechanism separately from business approvals.
Tell us which assets you use, whether it is personal or business, and if you need shared control. Ask about products, pricing and delivery on Telegram.
