Part 2: The Data Cable
Sarah did not move toward the door. Instead, she unclasped her purse, pulled out a short USB-C cable, and laid it on the desk next to the hardware wallet. “I brought the cord,” she said, her voice steadying. “You said last night on the phone that you didn’t have the right cable here. I bought this one at the store on my way.”
Tyler stared at the black braided cable. His left foot began to tap a rapid rhythm against the carpeted concrete floor. “That’s a standard power cable, Sarah. It doesn’t have the data lines required for hardware security modules. If we use a cheap retail cord, we could bridge the pins and fry the device’s secure element.”
“It’s a high-speed data transfer cable,” Sarah said. She pointed to the label on the plastic packaging she had just opened. “The box says it transfers up to ten gigabits per second. It’s for data.”
Tyler did not touch the cable. He picked up his coffee mug, took a long sip, and set it down precisely on a paper napkin. “Even with a data cable, my workstation isn’t configured for ledger verification. I don’t have the bridge client installed, and downloading it over the office network would violate our IT security policy.”
He looked over at me. I kept my gaze fixed on my monitor, where the Ledger Live bridge client was currently open in my background apps, fully updated and active. I did not close the window.
Sarah followed his gaze, looking at my desk. She walked two steps over and looked at my screen. She pointed to the small icon in my system tray. “Marcus has the bridge client open. I can see the logo.”
Tyler cleared his throat, a sharp, dry sound. “Marcus is running a database migration on a secure subnet. We can’t plug external hardware into his terminal without triggering an automatic audit log. You don’t want the compliance team looking at your personal assets, do you?”
“I don’t care about the compliance team,” Sarah said. Her voice was louder now, though still controlled. She picked up the hardware wallet from Tyler’s desk and walked over to my station. She placed the device on the clean desk space next to my keyboard, then laid the USB-C cable beside it. “Marcus, please. Just plug it in and open the public portfolio viewer. It doesn’t need to sign anything. It just needs to read the address.”
Tyler stood up from his chair. His shoulders were tense, his arms hanging straight at his sides. “Sarah, you’re crossing a line here. I told you, the shard pool hasn’t cleared. If you force a hardware query right now, you will disrupt the block index. You could permanently lock the transaction queue.”
He stepped toward my desk, reaching out as if to take the wallet back. But Sarah placed her hand flat over the device, pinning it to the desk. She looked directly at Tyler. “If the money is there, the public key will show it. Marcus, plug it in.”
I looked at the wallet under Sarah’s hand, then up at Tyler. Tyler’s forehead was damp under the fluorescent basement lights, and his hand remained outstretched, hovering inches from Sarah’s fingers.
