solver-fee Skill

"Fair compensation for coordination. 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
