Treasury

The Treasury<T> holds accumulated protocol fees (and forfeited dispute bonds) per collateral type. It is a shared object created once per coin type by the admin.

What goes in

• The protocol-fee slice of every trade (route_fees → treasury.deposit_fee).
• Forfeited dispute bonds after finalization (oracle_integration::drain_bond → treasury.deposit_fee).

What does NOT go in

• Creator fees are paid directly to the market creator at trade time.
• Collateral vault funds (share backing) are never touched by the treasury.
• LP incentive rewards live in a separate IncentiveVault<T>.

Operations

• create_treasury<T>(registry) — admin-only, creates the shared treasury.
• deposit_fee(fee) — called internally by trading functions.
• request_withdraw<T>(amount, registry, cap) — admin-only; sets unlock_at = now + timelock (minimum 1 hour).
• execute_withdraw<T>(amount, registry, cap) — admin-only; executes after timelock elapsed.
• View helpers: balance, total_collected, total_withdrawn.

Analytics

The treasury tracks total_collected and total_withdrawn so the community can audit how much protocol revenue has been earned and swept.
