Backup
When you create a new key, you'll receive a mnemonic phrase that can be used to restore that key. Backup the mnemonic phrase:
blockxd keys add mykey
{
"name": "mykey",
"type": "local",
"address": "blockx1n253dl2tgyhxjm592p580c38r4dn8023ctv28d",
"pubkey": '{"@type":"/ethermint.crypto.v1.ethsecp256k1.PubKey","key":"ArJhve4v5HkLm+F7ViASU/rAGx7YrwU4+XKV2MNJt+Cq"}',
"mnemonic": ""
}
**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.
# <24 word mnemonic phrase>
To restore the key:
$ blockxd keys add mykey-restored --recover

{
"name": "mykey-restored",
"type": "local",
"address": "blockx1n253dl2tgyhxjm592p580c38r4dn8023ctv28d",
"pubkey": '{"@type":"/ethermint.crypto.v1.ethsecp256k1.PubKey","key":"ArJhve4v5HkLm+F7ViASU/rAGx7YrwU4+XKV2MNJt+Cq"}'
}
To backup this type of key without the mnemonic phrase, do the following:
blockxd keys export mykey
Enter passphrase to decrypt your key:
Enter passphrase to encrypt the exported key:
-----BEGIN TENDERMINT PRIVATE KEY-----
kdf: bcrypt
salt: 14559BB13D881A86E0F4D3872B8B2C82
type: secp256k1
# <Tendermint private key>
-----END TENDERMINT PRIVATE KEY-----
$ echo "\
-----BEGIN TENDERMINT PRIVATE KEY-----
kdf: bcrypt
salt: 14559BB13D881A86E0F4D3872B8B2C82
type: secp256k1
# <Tendermint private key>
-----END TENDERMINT PRIVATE KEY-----" > mykey.export
To backup this type of key without the mnemonic phrase, do the following:
blockxd keys unsafe-export-eth-key mykey > mykey.export
**WARNING** this is an unsafe way to export your unencrypted private key, are you sure? [y/N]: y
Enter keyring passphrase:
$ blockxd keys import mykey-imported ./mykey.export
Enter passphrase to decrypt your key:
$ blockxd keys unsafe-import-eth-key mykey-imported ./mykey.export
Enter passphrase to encrypt your key:
Verify that your key has been restored using the following command:
$ blockxd keys list
[
{
"name": "mykey-imported",
"type": "local",
"address": "blockx1n253dl2tgyhxjm592p580c38r4dn8023ctv28d",
