J1USD is the Protocol Settlement Asset — the canonical unit of account for transportation, warehousing, Host services, insurance-like holds, and marketplace fees on AirJIT. It targets approximate USD parity while remaining independent from JIT security mechanisms.
Settlement properties
- Price stability for commercial contracts (target, not a guarantee)
- Settlement finality after attested events
- Programmable escrow and payments
- Cross-chain portability via BAL as a design goal
- Neutrality from governance voting power
Default denomination
Unless parties agree otherwise, logistics obligations are denominated in J1USD. Separating settlement from security prevents commercial volatility from destabilizing staking economics — and prevents staking power from capturing invoice rails.
