## .env settings
### MORPH_CHAIN_URL
URL to get side chain dump. Used on artifact get stage.
### MORPH_CHAIN_PATH
Path to get side chain dump. If set, overrides `CHAIN_URL`.
### NEOGO_VERSION
Version of neo-go docker container for side chain deployment.
## Side chain wallets
There is a wallet with GAS that used for contract deployment:
`wallets/wallet.json`. This wallet has one account with **empty password**.
```
$ neo-go wallet nep17 balance \
-w wallets/wallet.json \
-r http://morph-chain.neofs.devenv:30333
Account NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM
GAS: GasToken (d2a4cff31913016155e38e474a2c06d08be276cf)
Amount : 189826.0515316
Updated: 3909
NEOFS: NeoFS Balance (69550190e740b93f92dbd5dea52246f550391057)
Amount : 50

```
This way you can also monitor NeoFS internal balance of your account.
## NeoFS global config
NeoFS uses global configuration to store epoch duration, maximum object size,
container fee and other network parameters. Global configuration is stored in
netmap contract and managed by Inner Ring (Alphabet) nodes.
To change these parameters use `make update.*` commands. Command down below
changes epoch duration from 300 blocks (about 300 seconds with 1bps) to 30.
Script enters passwords automatically with `expect` utility.
```
$ make update.epoch_duration val=30
Changing EpochDuration configration value to 30
