However, the critical part of business operational security is the partner's OPSEC (operation security). If you own a partner contract and your wallet private key is leaked your earnings might be stolen each time you generate it. In such cases partner contract becomes worthless. ## **Purchase Trezor or Ledger Hardware Wallet** * Always purchase the hardware wallet from a certified reseller in your local market ## **Use a Proper Way of Seed Backup** * We recommend metallic tabs and engraving the seeds on it. * Use Shamir backup seed instead of classical seed phrase. * That gives you an opportunity to distribute seed in more than one location. * Read here: * We recommend Shamir 2/3 or 3/5. * Never make any digital backup on any device. * Prepare a backup device in case of loss or damage. * It might be hard to restore your device, but we recommend having at least one backup device that is well-stored. * Protect your hardware wallet with a strong pin. * We recommend at least 6 digits for operational and 10 digits for backup device. * Don't make it easy to guess. ## **Use a Multisig Wallet** * We recommend using [**safe.globa**l](https://safe.global/) multisig contract that can be an owner of the Partner contract. * That allows you to sell the partner contract in case you decide or transfer its ownership. * This protects you from a physical attack from the contract owner. * We recommend a 2/3 quorum.
