CAT Protocol One-click Script Minting Tutorial

Background

The Cat20 protocol @ProtocolCAT released on Fractal Bitcoin early this morning is a new protocol on the fractal network. Based on the new OP_CAT technology, developers can develop based on OP_CAT to implement some simple smart contract functions.

Here is a one-click script tutorial for mint on the Linux system.

mint prerequisites: $FB, a Linux server (2-core CPU 4GB memory)

• Official documentation https://github.com/CATProtocol/cat-token-box/blob/main/packages/tracker/README.md#prerequisite

Tutorial start:

A one-click script is used here to simplify everyone's construction. The code is written by Twitter user @ouyoung11. Welcome to follow.

The code is completely open source and the source code can be checked on GitHub. There are no background vulnerabilities or dangerous code.

① After logging in to the server, execute the following command to install the script:

cd ~ && wget -O /root/cat20-oooooyoung.sh https://github.com/nopapername/shell-oooooyoung/releases/download/cat20-oooooyoung/cat20-oooooyoung.sh && chmod +x cat20-oooooyoung.sh

② Enter the following code to enter the prompt interface of one-click script building (enter the numbers to execute the steps in sequence. After each step, run the following command to enter the script interface again).

bash ~/cat20-oooooyoung.sh

PS: If the pink interface in Figure 2 appears during the installation, just press Enter to continue

③ After the environment and fractal node are installed, synchronization has started automatically. Enter `bash ~/cat20-oooooyoung.sh` again to enter the script interface, and then enter 4 to view the node synchronization log

PS: Confirm that it is consistent with the latest block height of the fractal network  ④ Enter `bash ~/cat20-oooooyoung.sh` again. ⑤ Enter `bash ~/cat20-oooooyoung.sh` again to enter the script interface and enter 3. Perform cyclic minting of $CAT tokens. Because there are too many people playing, minting may fail and cause retries. Just hang up all the time - 9.11 Update: The script has been updated to manually set gas

• Enter `bash ~/cat20-oooooyoung.sh` to enter the script interface, enter 5 to check the balance

• Go directly to the website and enter the address to query https://cat20.app/ (I don’t know if it is official)

Summary of Problems

1. The created wallet address does not correspond to the unisat wallet address when imported?

• Because the generated wallet is in the path format of m/44', and the unisat import format defaults to m/86', so fill in `m/44'/0'/0'/0` or m/44'/0'/0'/0/0 format when importing, you can see it

• You can also view the FB balance and the marked assets by directly entering the newly generated wallet address in the block browserhttps://explorer.unisat.io/fractal-mainnet/address/bc1p9k67fd8jr4hnxd6k9lgh02g3dfeht2f5wdkyppya2cterlqakfdqy3ksdd

• Export the previous wallet (that is, this wallet.json file is your wallet data, and you only need to change this json file to switch wallets):

  cat ~/cat-token-box/packages/cli/wallet.json

• Import a new wallet (on a new server or after reinstalling the node, copy the previous wallet.json and re-mint):

  echo '{
    "accountPath": "Here is the format of the previous wallet address",
    "name": "Do not change here",
    "mnemonic": "Here is the mnemonic of the previous wallet"
  }' > ~/cat-token-box/packages/cli/wallet.json

3. If you want to modify the gas fee of the circular mint script, the steps are as follows: (The script has been updated to manually set GAS)

• Type `nano ~/cat-token-box/packages/cli/mint_script.sh`

• Modify the code (you can set the gas fee to your desired value, 100 gas in the example)

  sudo yarn cli mint -i 45ee725c2c5993b3e4d308842d87e973bf1951f5f7a804b21e4dd964ecd12d6b_0 5 --fee-rate 100

• Then press ctrl + x Enter y to save and exit, then re-run the mint script

4. Why does the problem of `No token found` occur when minting tokens?

This is usually caused by the node not being fully synchronized. Just wait for the node to be synchronized.

5. The minted tokens have not been received, the gas fee has not been deducted, and the txid of mint success cannot be found.

• You need to wait for the node to synchronize to the block height where you successfully minted

• Some gas is insufficient and cannot be mined. The gas fee can be checked here https://explorer.unisat.io/fractal-mainnet/block (the gas fee is currently as high as 420, and the cost-effectiveness of minting at this fee is not high)

6. Is there an error in the first step of the one-click script to install the node or check the log?

There are many strange errors. Generally speaking, it may be that the server environment configuration is different from mine. Because I haven't encountered it, I don't know how to solve it for the time being. You can add the following dc to discuss together.
