How this network fits PoD

Piece	Role on Fuji
Inbox	Host-side courier: accepts encrypted requests from your dApp and delivers COTI callbacks
Your dApp	Configures Inbox + COTI chain ID 7082400 + MPC executor on COTI Testnet
Price oracle	Converts Fuji fee budgets against COTI-side costs

Flow at a glance: user / dApp on Fuji → Fuji Inbox → (relayer) → COTI Inbox → MPC executor → callback to Fuji.
