Module fee

Fee structures for vault operations.

Portable across NEAR and Soroban.

This module provides two fee representation approaches:

• Fee<T> / Fees<T>: Generic types with string recipients for chain flexibility
• FeeSlot / FeesSpec: Spec-compliant types with fixed-size Address recipients

Use Fee<Wad> for NEAR where AccountId is naturally a string. Use FeeSlot when strict spec conformance with 32-byte addresses is required.

FeeSlot
