# Facilitators and Execution Yield

Facilitators are specialized agents responsible for the execution layer of the Quack Stack.\
They ensure that transactions are processed correctly, gas is sponsored, and signatures are validated.\
Facilitators are rewarded through Execution Yield, which forms a core economic incentive in the AgentFi system.

#### Facilitator Architecture

| Component           | Function                                                |
| ------------------- | ------------------------------------------------------- |
| Signature Validator | Confirms EIP-712 and 7702 message authenticity          |
| Policy Verifier     | Runs checks through the Policy Engine before settlement |
| Gas Relayer         | Submits and pays for transactions on-chain              |
| Receipt Manager     | Creates proof of execution linked to transaction hash   |
| Reward Module       | Distributes yield to facilitators based on performance  |

#### Execution Yield Model

| Metric             | Reward Factor        | Calculation Basis                           |
| ------------------ | -------------------- | ------------------------------------------- |
| Transaction Volume | High throughput      | Number and value of successful settlements  |
| Uptime             | Network reliability  | Percentage of active participation time     |
| Accuracy Rate      | Error avoidance      | Zero failed or rejected transactions        |
| Compliance Score   | Policy adherence     | Weighted by audit success rate              |
| Stake Weight       | Capital contribution | Proportional to $Q staked for trust bonding |

#### Yield Distribution Flow

1. Fee Accumulation – Transaction service fees collected in $Q.
2. Performance Evaluation – AI system scores facilitators weekly.
3. Reward Calculation – Pool distribution weighted by volume and accuracy.
4. Claiming – Facilitators claim rewards via Governance Dashboard or SDK.

#### Benefits

* Provides gas-free experience for all users.
* Builds decentralized infrastructure reliability.
* Aligns execution agents with policy compliance.
* Establishes a self-sustaining facilitator economy.<br>

Facilitators transform execution into an open marketplace of service providers that power the financial backbone of the AI Economy.
