The solver's incentive to find optimal solutions."* ## Overview **Solver Fee** implements fee mechanisms for intent solvers in Anoma-style architectures. Solvers coordinate between intent generators and validators, earning fees for finding optimal matches. ## GF(3) Role | Aspect | Value | |--------|-------| | Trit | 0 (ERGODIC) | | Role | COORDINATOR | | Function | Coordinates fee distribution between parties | ## Architecture ``` ┌─────────────────────────────────────────────────────────────────┐ │ SOLVER FEE FLOW │ ├─────────────────────────────────────────────────────────────────┤ │ │ │ Intent Creator Solver Validator Executor │ │ (+1 GEN) (0 COORD) (-1 VAL) (output) │ │ │ │ │ │ │ │ ▼ ▼ ▼ ▼ │ │ ┌───────┐ ┌────────┐ ┌──────────┐ ┌─────────┐ │ │ │ Offer │───────►│ Match │──────►│ Validate │──►│ Execute │ │ │ │+ fee │ │+ solve │ │+ verify │ │ │ │ │ └───────┘ └────────┘ └──────────┘ └─────────┘ │ │ │ │ │ │ │ ▼ │ │ │ ┌──────────┐ │ │ └─────────►│ Fee Pool │ │ │ └──────────┘ │ │ │ │ │ ▼ │ │ Solver Reward │ │ │ └─────────────────────────────────────────────────────────────────┘ ``` ## Fee Models ```python class FeeModel: """Base class for solver fee computation."""
