# DeepDive into Liquid: Part II - Asset Creation and Configuration
This is a multipart DeepDive that will focus on the Liquid Sidechain. It will be released in 3 Parts:
* [Part I](https://stacker.news/items/399400): Overview, Installation, and first Peg-In
* Part II (this): Asset Creation and Configuration
* Part III: Advanced Topics and Peg-out
## Assets
In Part I, we succesfully Pegged-In our BTC and received L-BTC, now lets use that L-BTC to do some interesting things with Asset Issuance:
* Let's begin by checking out these 2 commands[^1]:
- `$ sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS getwalletinfo`
"balance": {"bitcoin": 0.00149155}
- `$ sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS dumpassetlabels`
{"bitcoin": "6f0279e9ed041c3d710a9f57d0c02928416460c4b722ae3457a11eec381c526d"}
This is telling us that `bitcoin` is a label for an asset that has the UUID of `6f0279e9ed041c3d710a9f57d0c02928416460c4b722ae3457a11eec381c526d`. Everything in Liquid is an 'Asset' (including L-BTC) and each of these Assets can have different features, issuance, and restrictions.
Looking up this value on [https://blockstream.info/liquid/assets](https://blockstream.info/liquid/asset/6f0279e9ed041c3d710a9f57d0c02928416460c4b722ae3457a11eec381c526d) we can see info about it like its ticker, name, and circulating supply:

### Issuing our own Asset
* Issuing our own asset is straight-forward, as its a single line command in the client. Let's issue 10 new tokens and set the supply to be fixed (no re-issuance)
- `$ sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS issueasset 10 0 true`
{
"txid": dd3983619f67e7a743ccfd32e48bbdb591c1d44b86a71d442be95a2453c0479a,
"vin": 0,
"entropy": cd3d7319525b28b6500d0a0b4688d91392ba8192be9bc264ec9637a001907322,
"asset": 1e69f87952c26b8dfc80dda0427041a0279a0723ea12086b88b75752545e0d22,
"token": 2dc5fb795fd42e08adb9dd29b5ff14f4326ecd8443e1cdc31dc6666d7576ff89
}
* Checking out our wallet we see:
- `$ sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS getwalletinfo`
"balance": {"1e69f87952c26b8dfc80dda0427041a0279a0723ea12086b88b75752545e0d22": 10.00000000,"bitcoin": 0.00148701}
* We can see our wallet has 10 of our assets[^2], lets checkout what the [Liquid network knows about it](https://blockstream.info/liquid/asset/1e69f87952c26b8dfc80dda0427041a0279a0723ea12086b88b75752545e0d22):
![](2-part2-firstasset.png)
* So publiclly we know the following about our new asset:
- It cannot be re-issued
- It has only been issued once
- However both the issued amount and the circulating supply has been hidden from us.
* Let's create another asset and this time choose a different option:
- `$ sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS issueasset 10 0 false`
{"txid": "1dfdf2f3a393a7a7be9f1f58c8651565a29486851268027794e1b69f5227864f",
"vin": 0,
"entropy": "5a32df406eb3f8c4f9b59c669d411e3a5ed0fd75058c2483e5732ccc6b482722",
"asset": "03d63d6c373979954a4dda2afdd941a0de96a0739da455af1cdb1a2e2a63a9a5",
"token": "ac860f370aabb829b70283c05e13a327cccec8ad0eea5493980cca53dd6631f9"}
...and checking again what [the Liquid network knows about it](https://blockstream.info/liquid/asset/03d63d6c373979954a4dda2afdd941a0de96a0739da455af1cdb1a2e2a63a9a5)
* Lets set that to a variable for use later
```
$ export ISSUE='{"txid": dd3983619f67e7a743ccfd32e48bbdb591c1d44b86a71d442be95a2453c0479a,
"vin": 0,
"entropy": cd3d7319525b28b6500d0a0b4688d91392ba8192be9bc264ec9637a001907322,
"asset": 1e69f87952c26b8dfc80dda0427041a0279a0723ea12086b88b75752545e0d22,
"token": 2dc5fb795fd42e08adb9dd29b5ff14f4326ecd8443e1cdc31dc6666d7576ff89
}'
```
* Now we can utilize individual entries (using `jq` utility):
- `$ echo $ISSUE | jq .asset`
"1e69f87952c26b8dfc80dda0427041a0279a0723ea12086b88b75752545e0d22"
[^1]: The values E_RPCUSER and E_RPCPASS, where environmental variables we set in Part I
[^2]: Like in bitcoin, 1 integer unit is 100,000,000 base units (not sats, but equivalent concept)
