Verifying Your Mnemonic Phrase
cd $HOME/staking-deposit-cli
./deposit existing-mnemonic --chain mainnetEnsure you can regenerate the same eth2 key pairs by restoring your validator_keys
Using the pre-built staking-deposit-cli executable,
cd $HOME/staking-deposit-cli
./deposit existing-mnemonic --chain mainnetWhen the pubkey in both keystore files are identical, this means your mnemonic phrase is veritably correct. Other fields will be different because of salting.
