### Optional: Mint your own NFTs
7171

72-
This process will be simplified in the future.
72+
#### Start plutus-chain-index
7373

74+
Set environment variables:
75+
76+
``` shell
77+
$ pwd
78+
.../seabug
79+
$ export CARDANO_NODE_SOCKET_PATH=$PWD/data/cardano-node/ipc/node.socket
80+
$ mkdir -p chain-index
81+
$ export CHAIN_INDEX_PATH=$PWD/chain-index/chain-index.sqlite
82+
```
83+
84+
Fix permission problem for `node.socket` (if you receive error like: `plutus-chain-index: Network.Socket.connect: <socket: 35>: permission denied (Permission denied)`):
85+
86+
``` shell
87+
$ sudo chmod 0666 $CARDANO_NODE_SOCKET_PATH
88+
```
89+
90+
Building and run plutus-chain-index from the source:
91+
92+
```
93+
$ cd ..
94+
$ git clone [email protected]:input-output-hk/plutus-apps.git
95+
$ cd plutus-apps
96+
$ nix build -f default.nix plutus-chain-index
97+
$ result/bin/plutus-chain-index start-index --network-id 1097911063 --db-path $CHAIN_INDEX_PATH/chain-index.sqlite --socket-path $CARDANO_NODE_SOCKET_PATH
98+
```
99+
100+
The index should be synced for minting.
101+
102+
#### Prepare wallet
103+
104+
``` shell
105+
$ cd seabug
106+
$ nix develop
107+
$ scripts/prepare-wallet.sh
108+
new wallet generated:
109+
address: addr_test1vp3tywa08qjjj7mplzmwjs9kmes0ce3ud5da3x0wppu5e9qgxqhps
110+
PHK: 62b23baf3825297b61f8b6e940b6de60fc663c6d1bd899ee08794c94
111+
file: payment.addr
112+
file: payment.vkey
113+
file: pab/signing-keys/signing-key-62b23baf3825297b61f8b6e940b6de60fc663c6d1bd899ee08794c94.skey
114+
```
115+
116+
Add some Ada to your wallet:
117+
- by Nami wallet
118+
- or by [Faucet](https://testnets.cardano.org/en/testnets/cardano/tools/faucet/)
119+
120+
Check the result:

#### Mint your own NFT
131+
132+
If you have an image:
133+
134+
``` shell
135+
$ cd seabug
136+
$ scripts/mint-nft.sh 'image.jpeg' 'Title' 'Description' 'Token name'
137+
```
138+
139+
The script take some time to work, especially if you don't use effitient_nft_pab before (`cd plutus-use-cases/mlabs && nix develop -c cabal run efficient-nft-pab --disable-optimisation`).
140+
141+
If you already uploaded the image to nft.storage and have IPFC_CID (you can get it from nft.storage web interface).
142+
143+
``` shell
144+
$ cd seabug
145+
$ scripts/mint-nft.sh 'image.jpeg' 'Title' 'Description' 'Token name' k2cwueaf1ew3nr2gq2rw83y13m2f5jpg8uyymn66kr8ogeglrwcou5u8
