F ractal Bitcoin mainnet transaction fees soar, reaching 101 Sat/byte for high priority. The popularity of the Covenant Attested Token (CAT) protocol on the Fengyun Network may be the main reason for the soaring transaction fees on its mainnet.
The protocol features multiple features such as indexer-free, modular, programmable minting, and cross-chain interoperability, and can be executed on any OP_CAT-enabled Bitcoin-compatible blockchain.

CAT Protocol one-click command code casting tutorial
background
The Cat20 protocol @ProtocolCAT, which was released on Fractal Bitcoin in the early morning of the 11th, 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 command code tutorial for mint on Linux system.
mint prerequisites: $FB, a linux server (2-core CPU 4GB memory)
Official document https://github.com/CATProtocol/cat-token-box/blob/main/packages/tracker/README.md#prerequisite
Tutorial starts:
One-click command code is used here to simplify everyone's construction. The code is written by Twitter user @ouyoung11. Welcome to follow.
The program code is completely open source, and the source code can be checked on github. There are no background vulnerabilities or dangerous codes.
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 for one-click script building (enter the numerical execution steps in sequence, and run the following command after each step to enter the script interface again).
bash ~/cat20-oooooyoung.sh
PS: If the pink interface in Figure 2 appears during the installation process, just press Enter to continue.
③ After the environment and fractal nodes 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: Continue to the next step after confirming that the height is consistent with the latest block height of the fractal network https://explorer.unisat.io/fractal-mainnet/block
④ Enter `bash ~/cat20-oooooyoung.sh` again to enter the script interface, enter 2 to create a new Fractal Network btc wallet, and save the seed phrase and address, then transfer a little bit $FB to the address for gas. Participate in mint cat20 tokens
⑤ Enter `bash ~/cat20-oooooyoung.sh` again to enter the script interface, enter 3 to perform $CAT token recycling mint. Because there are many people playing, mint may fail and cause retry. Just hang up.
PS: The default gas fee is set to 30. If you want to set a higher point, the command for a single mint is as follows (the number in –fee-rate 1000 is the current gas):
sudo yarn cli mint -i 45ee725c2c5993b3e4d308842d87e973bf1951f5f7a804b21e4dd964ecd12d6b_0 5 –fee-rate 1000
mint successful ⑥ If you put the created wallet mnemonic vocabulary into the unisat wallet, the address will not match due to format problems, so there is no need to import it. Just enter the newly generated wallet address in the block browser to view the FB balance and marked assets https ://explorer.unisat.io/fractal-mainnet/address/bc1p9k67fd8jr4hnxd6k9lgh02g3dfeht2f5wdkyppya2cterlqakfdqy3ksdd
