Yield Vault

The RDR Reward Engine Backed by Real-World Work

SRU → Emission Model → On-Chain Distribution

---

🚀 Introduction

The Yield Vault is the financial core of the Ridera Protocol. It converts global mobility productivity — represented as SRU (Standardized Revenue Units) — into daily RDR emissions that are distributed to stakers.

Unlike traditional staking models that depend on:

❌ arbitrary APY ❌ token price manipulation ❌ inflationary emissions

Ridera’s Yield Vault uses a real-world backed emission curve based on verified SRU written into the Proof Registry.

This makes Ridera the world’s first yield system powered directly by human work.

🎯 Purpose of the Yield Vault

The Yield Vault serves three main responsibilities:

1. Compute daily RDR emissions

Using totalSRU values from the Proof Registry.

2. Distribute rewards to stakers

Based on each user’s share of the staking pool.

3. Enforce real-world backed token issuance

No SRU → No emission → No reward.

Yield is always grounded in real mobility activity.

🧱 High-Level Architecture

Proof Registry (totalSRU) ↓ Yield Vault (Compute Emissions) ↓ Stake-Based Distribution ↓ RDR Rewards → Users

The Yield Vault never sees raw earnings data — only standardized SRU totals.

🔷 1. Inputs to the Yield Vault

The Yield Vault reads directly from the Proof Registry:

cycleId totalSRU timestamp

It does NOT rely on off-chain data.

Only on-chain SRU totals can trigger emissions.

🔷 2. Emission Formula (Core Logic)

The Yield Vault uses Ridera’s dynamic emission formula:

dailyEmission = min( BASE_EMISSION + (totalSRU × SRU_Emission_Factor), MAX_EMISSION )

Variables:

Variable	Description
BASE_EMISSION	Minimum rewards for low-activity days
totalSRU	Verified SRU for the cycle (from Registry)
SRU_Emission_Factor	Multiplier linking SRU → RDR emission
MAX_EMISSION	Hard cap to prevent inflation

Properties:

• Scales with real work

• Bounded by protocol safety limits

• Predictable and transparent

• Resistant to manipulation

---

🔷 3. Emission Examples (Conceptual)

Although values will be tuned for mainnet, here is how emissions behave:

Low SRU day

Low SRU → BASE_EMISSION (minimum reward)

Medium SRU day

More SRU → Higher RDR (still below cap)

High SRU day

High SRU → MAX_EMISSION (cap reached)

This ensures sustainable token output even if global workforce grows exponentially.

---

🔷 4. Staker Reward Distribution

Once daily emission is computed:

userReward = (userStake / totalStake) × dailyEmission

Characteristics:

• purely proportional

• no boosters

• no tiers

• no unfair multipliers

Ridera maintains a flat, fair staking model.

🔷 5. Emission Lifecycle (End-to-End)

Oracle Verification → SRU Engine → Proof Registry → Yield Vault → Stakers

Complete Flow:

1. Workers submit proofs

2. Oracle verifies

3. SRU Engine standardizes

4. Proof Registry stores cycle

5. Yield Vault computes daily emissions

6. Stakers receive proportional RDR

Every reward is backed by real work from the previous cycle.

---

🔷 6. Yield Vault Smart Contract Responsibilities

✔ Reading SRU totals from Proof Registry

✔ Applying Ridera emission formula

✔ Distributing RDR to stakers

✔ Writing emission logs on-chain

✔ Providing transparency for auditors and the public

The contract is minimal and fully deterministic.

---

🔷 7. Anti-Inflation Mechanisms

Ridera prevents oversupply through:

Hard emission cap

MAX_EMISSION ensures daily reward output is bounded.

Dynamic SRU multiplier

SRU_Emission_Factor can be updated by governance in future versions.

BASE_EMISSION floor

Provides stability during early network phases.

Secure & transparent proof-of-workflow

Fake earnings cannot generate SRU → cannot generate RDR.

---

🔷 8. Future Upgrades (Yield Vault v2)

Ridera will introduce enhancements such as:

• region-specific yield pools

• multi-vault reward tiers

• seasonal emission curves

• governance-adjustable parameters

• zk-based SRU verification inputs

These upgrades are designed to scale with global mobility adoption.

---

🔥 Why the Yield Vault Makes Ridera Unique

✔ Real-world backed emissions

✔ Zero speculation dependence

✔ Fully on-chain, transparent logic

✔ No APR manipulation

✔ Tied directly to global human productivity

✔ First-of-its-kind RWA yield model

Ridera’s Yield Vault is the first reward system truly powered by verified human effort, not financial engineering.
