Cash Flows on Mantle
PPA Protocol fractionalizes contracted solar revenue into on-chain tokens. Earn daily cash flows from a real Power Purchase Agreement - compounded automatically by an AI agent.

Fund real-world infrastructure from $10.
Earn its cash flows. Let an AI agent compound the idle float.

The Problem
Infrastructure yield is
institutionally gated
$1M+
Minimum Ticket
Infrastructure assets generate decade-long contracted cash flows - among the most predictable yield instruments that exist. Access is gated behind private placement structures and illiquid lockups.
No Rail
No On-chain Infrastructure
The digital-solar model is already validated off-chain. Companies like Sunday Grids let users fund commercial rooftop solar. But the flow lives in private databases - no transferability, no composability, no transparency.
25/30
Days of Dead Capital
Energy credits accrue daily but bills are paid monthly. For roughly 25 of every 30 days, accumulated credits sit idle earning nothing. At protocol scale, the idle float is substantial.
The RWA
The asset is not the panel.
It is the contract.
A commercial building legally committed to buying solar power at a fixed discounted tariff for 10–15 years. That contracted revenue stream is the RWA. The protocol fractionalizes it down to a $10 ticket.
Reference Plant - Chennai
| Capacity | 100 kW commercial rooftop |
| Daily generation | 400 kWh |
| PPA tariff | ₹4.50/kWh |
| Grid tariff (offtaker avoids) | ₹7.00/kWh - saves 36% |
| Funding price | ₹40/W → 100,000 PPAT |
| PPA term | 15 years |
Token Design
1 PPAT =
1 Watt
of funded plant capacity
ERC-20 on Mantle. Transferable. Snapshot-eligible for daily revenue distribution.
Minimum ticket: $10 ≈ 208 PPAT. Architecture is asset-agnostic - any infrastructure with a paying offtaker and verifiable output qualifies.

Unit Economics
Real numbers.
Real returns.
Every metric is anchored to a real PPA. These exact numbers appear in the demo UI so judges can verify the math live.
| Metric | Per 1,000 PPAT (1 kW, ~$48) | Per $10 ticket (≈208 PPAT) |
|---|---|---|
| Daily generation | 4.0 kWh | 0.83 kWh |
| Daily credit (USDT) | ₹18 ≈ $0.216 | ≈ $0.045 |
| Annual credits | ₹6,570 ≈ $79 | ≈ $16.40 |
| Base PPA yield | 16.4% p.a. | 16.4% p.a. |
| USDY layer (AI agent) | +4–5% on idle float | +4–5% on idle float |
| Total potential | ~21% | ~21% |
Agent-Attributed Yield
Average idle float per 1 kW funder ≈ $5.30. At 4.5% USDY APY → +$0.24/year per kW. Small per user, scales linearly with TVL, every routing decision recorded on-chain.
ERC-8004 AI Agent
Deterministic. Autonomous. Auditable.
MONITOR
Default - always running
Read balance B, days-to-bill D, USDY position P for every funder
DEPLOY
D > 5 AND idle B > $5
Sweep (B − 20% buffer) to USDY pool → emit AgentDecision(DEPLOY)
HOLD
2 < D ≤ 5
No movement - emit AgentDecision(HOLD, reason: WINDOW_HOLD) on-chain
RETRIEVE
D ≤ 2 AND position > 0
Unwind full USDY position including accrued yield → CreditVault
SETTLE
D = 0
Transfer bill amount from CreditVault → BillPay. Zero clicks from funder.
