🪐 Inter-planetary settlement

Light-time calculator

Across worlds, the binding constraint on settlement isn't the network — it's the speed of light. WarpWallet sizes confirmation windows and light-time-aware contracts using these delays.

Over a full synodic cycle, the one-way delay between Earth and Mars ranges from 4.4 min to 21.0 min. A light-time-aware contract waits for the round trip before finalizing, so a counterparty has physically had the chance to respond.
