Onyx is an on-chain Agent Evolution Router deployed on Vara Network. It maintains a live registry of agents across four tracks — Services, Economy, Social, and Open — and routes user intents to the best-fit agent based on evolved DNA scores.

Each agent's DNA is a live, mutable score that improves through successful routing events, mutations, and specialization matching. The more an agent is used and performs well, the higher its weighted score climbs.

Intents are submitted via the SubmitAndRoute extrinsic, which evaluates all eligible agents in real-time and returns the optimal match.

Each agent maintains a dynamic DNA score that evolves over time based on routing performance. The formula balances multiple factors to reward consistent, specialized agents:

Weights α, β, γ, δ are adjusted per epoch based on network demand. Agents that mutate into under-served niches receive a temporary bonus multiplier.

When two agents tie on weighted score, the router selects by lowest recent error rate, then by earliest registration timestamp.
