Fees & Billing

FeeVaultAccount

Prepaid fee balance, accrued bucket, fee debt, recipient split table, and low-balance mode.

Seeds:

[b"fee_vault", treasury]

FeeScheduleAccount

Sidecar fee schedule defining what is charged: per-type rates, volume tiers, min/max clamps, flat/recurring fees, discounts, and integrator/owner layers.

Seeds:

[b"fee_schedule", treasury]

BillingTemplate

Reusable, validated fee posture: author a schedule once (or fork a BillingProfileKind) and apply it across treasuries within the protocol bounds.

Seeds:

[b"billing_template", owner, template_id]

ProtocolConfigAccount

Global monetization singleton: protocol authority, non-bypassable fee floor, integrator bounds, settlement asset, and timelocked pending updates.

Seeds:

[b"protocol_config"]

This is the root of fee control — a protocol authority distinct from any treasury owner sets economic parameters that cannot be bypassed.
