Satelink Network — Smart Contracts

Solidity smart contracts powering the Satelink DePIN network. Deployed on Polygon PoS (Chain ID: 137).

Contracts

Contract	Address (Polygon Mainnet)	Purpose
NodeRegistryV2	TBD	On-chain node identity and registration
RevenueVault	TBD	USDT treasury holding contract with withdrawal caps
SplitEngine	TBD	50/30/20 revenue split calculator
RevenueDistributor	TBD	USDT distribution to node/platform/builder pools
ClaimsContract	TBD	EIP-712 signed claim-to-payout lifecycle
ClaimsWithdrawals	TBD	Merkle-proof epoch claims with deadlines
EpochAnchor	TBD	On-chain epoch root anchoring (oracle)
EligibilityPolicy	TBD	Epoch scoring rules and eligibility thresholds
GovernanceTimelock	TBD	24-hour timelock for governance operations

Economic Model

Revenue from paid operations is split on-chain:

• 50% → Node Operator Pool
• 30% → Platform Fee (core treasury)
• 20% → Builder/Distribution Pool

The SplitEngine contract enforces this split with governance-controlled basis points. No single party can modify the split unilaterally — changes require CONFIGURATOR_ROLE and are subject to governance timelock.

Revenue Flow

[Paid Ops] → RevenueVault → SplitEngine → RevenueDistributor
                                              ├── 50% → Node Operators
                                              ├── 30% → Core Treasury
                                              └── 20% → Builder Pool

Claims Model

Node operators claim rewards using a pull model:

1. Platform computes epoch earnings off-chain
2. Merkle root is anchored on-chain via EpochAnchor
3. Operators submit claims with Merkle proofs via ClaimsWithdrawals
4. 48-day claim deadline enforced on-chain

Security Features

• AccessControl: Role-based permissions (ADMIN, REGISTRAR, ORACLE, etc.)
• Pausable: Emergency pause on all critical contracts
• ReentrancyGuard: Protection against reentrancy attacks
• Withdrawal Caps: RevenueVault auto-pauses on cap breach

• Merkle Proofs: Trustless epoch claim verification
• 24h Timelock: Governance operations require delay
