help Opendime FAQ

How does Opendime work as a physical Bitcoin wallet?

Opendime is a hardware wallet designed for secure offline storage of cryptocurrencies like Bitcoin. It uses a microSD card to store private keys completely offline, keeping them safe from hackers. To spend the funds, you must physically break the seal on the device to access the seed phrase.

Can I reuse an Opendime after it has been unsealed?

Once an Opendime is unsealed to reveal the private key, it should be considered compromised and not reused. The entire concept relies on the physical integrity of the device to prove the funds have never been touched. You should immediately transfer the Bitcoin to a new wallet.

How do I know the balance on my Opendime hardware wallet?

You can safely plug the Opendime into any computer or mobile device via a connected USB interface to check its balance. The device acts as a read-only USB drive, allowing you to view the public address. You can then paste this address into a block explorer to verify the funds.

What cryptocurrencies are supported by Opendime?

Opendime was originally designed specifically for Bitcoin and remains most popular for that cryptocurrency. The hardware can technically support other similar UTXO-based coins, but the native user interface is optimized for Bitcoin transactions. Users looking to store altcoins should look for alternative hardware wallets.
