To complete the demo, you need to set up the following toolchains:
First, clone it from GitHub:
git clone https://github.com/RGB-WG/rgb.git
Then, build it, copy the binary to ~/.cargo/bin/
:
cd rgb
cargo build --package rgb-wallet --bin rgb --release
cp target/release/rgb ~/.cargo/bin/
Run make up
to start the development environment
git clone https://github.com/bitlightlabs/bitlight-local-env-public/

To create a RGB20 contract, just clone this repo to you local machine. Then compile and run it.
git clone https://github.com/bitlightlabs/bitlight-rgb20-contract
cd bitlight-rgb20-contract
edit main.rs, change the beneficiary to alice's address
let beneficiary_txid =
Txid::from_hex("d6afd1233f2c3a7228ae2f07d64b2091db0d66f2e8ef169cf01217617f51b8fb").unwrap();
let beneficiary = Outpoint::new(beneficiary_txid, 1);
make run
The issued contract data:
{"ticker":"TEST","name":"Test asset","details":null,"precision":"centiMicro"}
amount=adMhBHaQ, owner=bc:tapret1st:311ec7d43f0f33cda5a0c515a737b5e0bbce3896e6eb32e67db0e868a58f4150:1, witness=~
totalSupply=adMhBHaQ
Contracts are available in the examples directory
---------------------------------
./examples:

-rw-r--r-- 1 bitlight staff 27456 Mar 15 19:57 rgb20-simplest.rgba
---------------------------------
Now, we are creating a RGB20 #TEST contract, which stores in examples
fold.
Before importing contracts, let's import our wallets to rgb.
Export ESPLORA_SERVER env for esplora-api endpoint:

After that, we can inspect contracts state with rgb state
command.
get the state of the contract for Alice

, which belongs to Alice.
There are about five steps in a complete transfer:
- Create an invoice
- Construct a PSBT
- Make a transfer
- Accept the transfer
- Sign the PSBT and broadcast it
To receive 1,000 #Test, Bob needs to create an invoice and send it to Alice.
$ rgb -d .bob invoice $RGB20_CONTRACT RGB20Fixed 2000

transfer.consignment alice.psbt
The consignment is saved in the transfer.consignment
file, and needs to be sent to Bob, who is waiting to accept it.
After receiving the transfer.consignment
file, Bob could validate it before accepting.
$ rgb -d .bob validate transfer.consignment
The provided consignment is valid
Bob accepts the consignment:
$ rgb -d .bob accept -f transfer.consignment
Transfer accepted into the stash
Let's inspect the psbt file:
$ hal psbt decode --regtest alice.psbt

Now, it's Alice's turn to sign the PSBT file and broadcast it.
Sign the PSBT with sparrow, hal, or bdk-cli.
After broadcasting, mine 1 block.
cargo run --bin broadcast_tx
cd <bitlight-local-env-public>
make core-cli
mint 1
At that time, Bob and Alice would get different outputs with rgb state
and rgb validate
.
