Export state

Export state from a given –chain (default: foundation) to a file. This command requires the chain to be synced with –fat-db on.

Flags:

• --no-code Don’t export account code.
• --no-storage Don’t export account storage.

Options:

• --at <BLOCK> Take a snapshot at the given block, which may be an index, hash, or latest. Note that taking snapshots at non-recent blocks will only work with –pruning archive
• --format <FORMAT> Export in a given format. FORMAT must be either ‘hex’ or ‘binary’. (default: binary)
• --max-balance <WEI> Don’t export accounts with a balance greater than specified.
• --min-balance <WEI> Don’t export accounts with balance less than specified.

Example:

openethereum export state ./export-state-file.bin

Export blocks

Export blocks into the given –chain database (default: foundation). This command requires the chain to be synced with –fat-db on.

Options:

• --format <FORMAT> Export in a given format. FORMAT must be either ‘hex’ or ‘binary’. (default: binary)
• --from <BLOCK> Export from block BLOCK, which may be an index or hash.
• --to <BLOCK> Export to (including) block BLOCK, which may be an index, hash or latest.

Example:

openethereum export blocks --chain goerli ./export-blocks-goerli.bin

Import

Import blockchain from a file to the given –chain database (default: foundation).

Options:

• --format <FORMAT> Import in a given format. FORMAT must be either ‘hex’ or ‘binary’. (default: auto)

Example: openethereum import ./export-blocks-file.bin

Account new

Create a new account (and its associated key) for the given –chain (default: foundation).

Example:

openethereum --chain goerli account new

Account list

List existing accounts of the given –chain (default: foundation).

Example:

openethereum --chain goerli account list
0x00780865dcc3c7dbffd943136107e70b8270286b
0x00dfc93112abd2578503b667b95491b101281f2b

Account import

Import accounts from JSON UTC keystore files to the specified –chain (default mainnet).

Example:

openethereum --chain goerli account list
0x00780865dcc3c7dbffd943136107e70b8270286b
0x00dfc93112abd2578503b667b95491b101281f2b


$ openethereum account import --chain goerli ./keystore-file.json 
1 account(s) imported

$ openethereum --chain goerli account list
0x003324332f7a9c2fb9536fcc4246a0bb4ea1b63f
0x00780865dcc3c7dbffd943136107e70b8270286b
0x00dfc93112abd2578503b667b95491b101281f2b

Db kill

Clean the database of the given –chain (default: foundation).

Example:

openethereum db kill --chain goerli
Database deleted.

Db reset

Removes <NUM> latest blocks from the db

Example:

openethereum db reset --chain goerli 5
Successfully reset db!

Daemon

Launch OpenEthereum as a daemon.

Example:

openethereum daemon ~/openethereum-daemon.pid --chain goerli

Snapshot

Make a snapshot of the database of the given –chain (default: foundation).

Example:

openethereum snapshot ~/goerli.snapshot --chain goerli

Options:

    --at <BLOCK>    Take a snapshot at the given block, which may be an index, hash, or "latest". Note that taking
                    snapshots at non-recent blocks will only work with --pruning archive

Restore

Restore database of the given –chain (default: foundation) from snapshot.

Example:

openethereum restore ~/goerli.snapshot --chain goerli

Tools hash

Hash a file using Keccak-256 algorithm.

Example:

openethereum tools hash ./some_file_to_hash.zip

Signer new-token

Generate new token for the given –chain (default: foundation).

Example:

openethereum signer new-token --chain goerli
