### 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`
|
||||
Issuing assets is pretty straight forward, it can be roughly broken down into 3 main steps[^3]:
|
||||
|
||||
1. Generate a Legacy Address[^4] and PUBKEY for that address
|
||||
2. Generate a Contract Hash
|
||||
3. Issue the Asset
|
||||
|
||||
* STEP 1a: Let's generate our legacy address and set the output to a variable
|
||||
`$ LEG_ADDRESS=$(sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS getnewaddress "" legacy`)

|
||||
|
||||
* STEP 1b: Set this address to a variable for use later and generate the public key.
|
||||
- `$ export LEG_ADDRESS="lq1qq2s92....."`
|
||||
- `$ sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS getaddressinfo $LEG_ADDRESS | jq '.pubkey'`

|
||||
|
||||
- `$ export PUBKEY="025aa49d444a150c99c904c8e779e5317aff4aee15ee9171f450e14af9dd8b8780"`
|
||||
|
||||
* STEP 2: In order to generate the contract hash, it requires a few steps - so I've simplified it by making a bash script. Copy this into a file named `gen_asset_contract.sh` and mark as executable
|
||||
|
||||
```
|
||||
#!/bin/bash
|
||||
#set -x
|
||||
|
||||
shopt -s expand_aliases
|
||||
|
||||
### FILENAME: gen_asset_contract.sh
|
||||
### USAGE: ./gen_asset_contract.sh PUBKEY
|
||||
|
||||
if [ -z "$1" ]
|
||||
then
|
||||
echo "Please supply PUBKEY before running"
|
||||
exit 1
|
||||
fi
|
||||
|
||||
PUBKEY=$1
|
||||
|
||||
###EDIT THESE VALUES###

||||
|

DOMAIN="nulldata.org"

||||
NAME="StackerNews-Demo1"

|

TICKER="SND-1"
|
||||
CONTRACT='{"entity":{"domain":"'$DOMAIN'"},"issuer_pubkey":"'$PUBKEY'","name":"'$NAME'","precision":'$PRECISION',"ticker":"'$TICKER'","version":'0'}'
|
||||
CONTRACT_HASH=$(echo -n "${CONTRACT}" | sha256sum | sha256sum | sed 's/ .*//g')
|
||||
|
||||
#Generate a byte-aligned reveresed CONTRACT_HASH for use in asset Creation
|
||||
TEMP=$CONTRACT_HASH
|
||||
LEN=${#TEMP}
|
||||
until [ $LEN -eq "0" ]; do
|
||||
END=${TEMP:(-2)}
|
||||
CONTRACT_HASH_REV="$CONTRACT_HASH_REV$END"
|
||||
TEMP=${TEMP::$((${#TEMP} - 2))}
|
||||
LEN=$((LEN-2))
|
||||
done
|
||||
|
||||
### END EDITING HERE ###
|
||||
echo CONTRACT=$CONTRACT
|
||||
echo CONTRACT_HASH=$CONTRACT_HASH
|
||||
echo CONTRACT_HASH_REV=$CONTRACT_HASH_REVT_HASH_REV=$CONTRACT_HASH_REV
|
||||
```
|
||||
|
||||
* STEP 2: Now we can use the script we saved before to generate the contract:
|
||||
|
||||
- `$ ./gen_asset_contract.sh $PUBKEY`
|
||||
|
||||
CONTRACT={"entity":{"domain":"nulldata.org"},"issuer_pubkey":"025aa49d444a150c99c904c8e779e5317aff4aee15ee9171f450e14af9dd8b8780","name":"StackerNews-Demo1","precision":8,"ticker":"SND-1","version":0}
|
||||
|
||||
CONTRACT_HASH=df4bd5aec71f808f78b752cbaac783019fa20268265f66baa406e4202b77e4a1
|
||||
|
||||
CONTRACT_HASH_REV=a1e4772b20e406a4ba665f266802a29f0183c7aacb52b7788f801fc7aed54bdf
|
||||
|
||||
|
||||
* STEP 2: Finally export those variables via bash to use later:
|
||||
|
||||
```
|
||||
export CONTRACT={"entity":{"domain":"nulldata.org"},"issuer_pubkey":"025aa49d444a150c99c904c8e779e5317aff4aee15ee9171f450e14af9dd8b8780","name":"StackerNews-Demo1","precision":8,"ticker":"SND-1","version":1}
|
||||
|

export CONTRACT_HASH=7d6bf3e3228fd00e9591c4c6bd1163d088a387e95d29fdfcf2e4e5035a137a94

export CONTRACT_HASH_REV=947a135a03e5e4f2fcfd295de987a388d06311bdc6c491950ed08f22e3f36b7d

The publication of asset metadata info on Liquid works on a `.well-known` system where specific files are published on a webserver that you control. There are a few different steps to accomplish this, so lets begin
|
||||
|
||||
* The first step is we need to generate a `legacy` address in case we ever want to delete the asset from the registry later[^3]
|
||||
- `sudo ./scripts/app compose elements exec node elements-cli -rpcuser=$E_RPCUSER -rpcpassword=$E_RPCPASS getnewaddress "" legacy`

[^2]: Like in bitcoin, 1 integer unit is 100,000,000 base units (not sats, but equivalent concept)
|
||||
[^3]: Using a legacy address for this task imposes no real implications to your security since its only used to remove assets from the registry. Its possible to do this with a non-legacy address, but more steps are involved and we will need to use other tools rather than what's already built-in to Elements node, so we will just use a legacy address for this.

[^3]: Technically just running `elements-cli issueasset 10 0` is enough to issue an asset, however there will be limitations later on when trying to register the asset, burn, remove, etc.
