Editor's note: Today, the transaction fees of the Fractal mainnet soared to more than 40 satoshis/byte, and the high-priority fees soared to more than 100 satoshis/byte. It is reported that today a team launched a new UTXO-based token protocol on Bitcoin, called the Covenant Attested Token (CAT) protocol, which has multiple features such as no indexer required, modularity, programmable casting, and cross-chain interoperability. The CAT Protocol can run on any Bitcoin-compatible blockchain that activates OP_CAT. The community infers that this may be the main reason for the surge in transaction fees on the Fractal mainnet. Crypto KOL 0x oooooyoung shared how to cast the protocol token with one click through a script. The full text is reproduced as follows:

CAT Protocol One-click Script Casting Tutorial

background

The Cat 20 protocol @ProtocolCAT was released on Fractal Bitcoin early this morning. It 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 the Linux system mint.

mint Prerequisites: $FB, a Linux server (2 cores CPU 4 GB memory)

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

Tutorial starts:

A one-click script is used here to simplify your setup. The code is written by Twitter user @ouyoung 11, 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/cat 20-oooooyoung.sh https://github.com/nopapername/shell-oooooyoung/releases/download/cat20-oooooyoung/cat20-oooooyoung.sh chmod +x cat 20-oooooyoung.sh

② Enter the following code to enter the prompt interface of one-click script building (enter the number execution steps in sequence, and run the following command after each step to enter the script interface again).

bash ~/cat 20-oooooyoung.sh

One-click script

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

Enter Skip

③ After the environment and fractal nodes are installed, synchronization has started automatically. Enter `bash ~/cat 20-oooooyoung.sh` again to enter the script interface, and then enter 4 to view the node synchronization log

PS: Continue to the next step after confirming that it is consistent with the latest block height of the Fractal Network https://explorer.unisat.io/fractal-mainnet/block

Synchronize Node

④ Enter `bash ~/cat 20-oooooyoung.sh` again to enter the script interface, enter 2 to create a new fractal network btc wallet, save the mnemonic and address, and then transfer a little bit of $FB to the address as gas to participate in minting cat 20 tokens

Create a wallet address

⑤ Enter `bash ~/cat 20-oooooyoung.sh` again to enter the script interface, and enter 3 to perform a circular mint of $CAT tokens. Because there are too many people calling, the mint may fail and cause retries. Just hang up.

PS: The default gas fee is set to 30. If you want to set a higher gas fee, the command for a single mint is as follows (the number of --fee-rate 1000 is the current gas fee):

sudo yarn cli mint -i 45 ee 725 c 2c 5993 b 3 e 4 d 30884 2d 87 e 973 bf 1951 f 5 f 7 a 804 b 21 e 4 dd 964 ecd 1 2d 6 b_ 0 5 --fee-rate 1000 

No gas

Mint Success

⑥ If you import the created wallet mnemonics into the unisat wallet, the address will not match due to formatting issues, so you don’t need to import it. Just enter the newly generated wallet address in the block browser to view the FB balance and the marked assets https://explorer.unisat.io/fractal-mainnet/address/ bc 1 p 9 k 67 fd 8 jr 4 hnxd 6 k 9 lgh 02 g 3d feht 2 f 5 wdkyppya 2c terlqakfdqy 3 ksdd
