Crypto Wallet Security: Four Checks Before Funding

Trace the seller through the manufacturer's official reseller directory, not a marketplace badge alone. Check the exact model and the seller shown at checkout. On arrival, follow the model's official authenticity procedure and install companion software only from the official download path. Packaging is one signal, not a guarantee. If anything is inconsistent, do not fund the wallet; contact the manufacturer through its own website.

Create the backup through the device's official setup workflow. Follow its exact format: words, shares and optional passphrases are not interchangeable. Keep the backup offline and protected against both theft and damage. A second copy can reduce one-location loss while increasing exposure if badly stored. A durable metal carrier may help with physical damage, but it cannot stop theft or fix an incorrectly recorded backup. Check word count and standard compatibility before buying any accessory.

Confirm the network, destination, amount and fees using the official wallet workflow. With hardware, compare against the device display, not just a browser overlay. Token approvals and contract interactions can authorize spending rather than transfer a fixed amount. A hardware wallet cannot make a malicious approval safe. Do not sign because a support agent, giveaway or timer says you must. Disconnect and investigate through official documentation if the request differs from your intent.

Use the manufacturer's supported backup-check procedure on the new setup first. Where a recovery rehearsal is appropriate, follow the exact model instructions using an empty or deliberately tiny test wallet. Do not improvise recovery by entering hardware-wallet secrets into a computer. Then make a small transfer and confirm it arrived on the expected network. Keep a private plan for locating the backup and identifying the recovery method; do not include secrets in ordinary notes, email or this checklist.
