CKB Transaction Firewall CKB Transaction Firewall

Step 1: Install the CLI

Install the CLI globally:

Terminal window
npm install -g @ckb-firewall/cli

Verify the installation and connect to testnet:

Terminal window
ckb-firewall inspect

You should see a table of current blacklist entries with their status. Something like:

┌─────────────────────────────────────────────┬──────────┬──────────────┐
│ Lock args                                   │ Status   │ Expires      │
├─────────────────────────────────────────────┼──────────┼──────────────┤
│ 0xababababababababababababababababababababab  │ active   │ permanent    │
│ 0x3f54dea35bcc7a0efef541d361799f77bd1b858  │ active   │ permanent    │
└─────────────────────────────────────────────┴──────────┴──────────────┘
Registry: 0xa3dcb46f... | Validators: 5 | Threshold: 3-of-5

The exact entries shown depend on the current state of the testnet registry.

If you see this output, the CLI is installed and can reach the live registry. Continue to Step 2.
