For better URLs, the content folder has been renamed 'docs' and all other files have been moved up a level. Also, non-docs images have been moved to the static folder at the top level where they belong. Many relative paths had to be fixed to make this work.

# Start a New Genesis Ledger in Stand-Alone Mode
|
|
|
|
In stand-alone mode, you can have `rippled` create a new genesis ledger. This provides a known state, with none of the ledger history from the production XRP Ledger. (This is very useful for unit tests, among other things.)
|
|
|
|
* To start `rippled` in stand-alone mode with a new genesis ledger, use the `-a` and `--start` options:
|
|
|
|
```
|
|
rippled -a --start --conf=/path/to/rippled.cfg
|
|
```
|
|
|
|
For more information on the options you can use when starting `rippled` in stand-alone mode, see [Commandline Usage: Stand-Alone Mode Options](../commandline-usage.md#stand-alone-mode-options).

In a genesis ledger, the [genesis address](../../concepts/accounts/addresses.md#special-addresses) holds all 100 billion XRP. The keys of the genesis address are [hardcoded](https://github.com/XRPLF/rippled/blob/94ed5b3a53077d815ad0dd65d490c8d37a147361/src/ripple/app/ledger/Ledger.cpp#L184) as follows:
|
|
|
|
**Address:** `rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh`
|
|
|
|
**Secret:** `snoPBrXtMeMyMHUVTgbuqAfg1SUTb` ("`masterpassphrase`")
|
|
|
|
## Settings in New Genesis Ledgers
|
|
|
|
In a new genesis ledger, the hard-coded default [Reserve](../../concepts/accounts/reserves.md) is **200 XRP** minimum for funding a new address, with an increment of **50 XRP** per object in the ledger. These values are higher than the current reserve requirements of the production network. (See also: [Fee Voting](../../concepts/consensus-protocol/fee-voting.md))
|
|
|
|
By default, a new genesis ledger has no [amendments](../../concepts/networks-and-servers/amendments.md) enabled. If you start a new genesis ledger with `--start`, the genesis ledger contains an [EnableAmendment pseudo-transaction](../../references/protocol/transactions/pseudo-transaction-types/enableamendment.md) to turn on all amendments natively supported by the `rippled` server, except for amendments that you explicitly disable in the config file. The effects of those amendments are available starting from the very next ledger version. (Reminder: in stand-alone mode, you must [advance the ledger manually](advance-the-ledger-in-stand-alone-mode.md).)
