How It Works

From Sun to Token to Yield

The asset is not the solar 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.

01

Deposit USDT

Send USDT to PlantEscrow. Funds are held until the plant capacity round closes. Minimum $10 - approximately 208 PPAT tokens.

02

Receive PPAT

Get minted PPAT tokens. 1 token equals 1 watt of funded plant capacity. Transferable ERC-20 on Mantle.

03

Earn Daily Revenue

The plant generates kWh daily. A signed oracle pushes readings on-chain. The revenue splitter distributes USDT credits pro-rata.

04

AI Agent Compounds

Autonomous ERC-8004 agent routes idle credits into Mantle USDY yield pools - retrieving them automatically before bills are due.

ERC-8004 AI Agent

Deterministic. Autonomous. Auditable.

No LLM in the transaction path. Every fund-moving decision is deterministic threshold logic with on-chain-verifiable inputs. Every action - including HOLD - emits an AgentDecision event on Mantle.

00
MONITOR
Continuous watch. Reads balances, days-to-bill, deployed positions every 15 seconds.
01
DEPLOY
D > 5 days and idle > $5 - sweep 80% to USDY yield pool, preserve 20% buffer.
Active in demo
02
HOLD
2 < D ≤ 5 - wait, emit reason code on-chain. No unnecessary moves.
03
RETRIEVE
D ≤ 2, position > 0 - unwind full USDY position including accrued yield.
04
SETTLE
D = 0 - pay bill from CreditVault. Zero clicks from the funder.
