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
yaml Copy code
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:
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:
Workers submit proofs
Oracle verifies
SRU Engine standardizes
Proof Registry stores cycle
Yield Vault computes daily emissions
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.
