Prioritized Security Risk Register

Merged vulnerability threats ranked by severity, blast radius, and mitigation complexity.

ID	Vulnerability / Threat Vector	Severity	Blast Radius	Mitigation Strategy
SEC-01	Oracle Manipulation & Flash Loan Attacks	CRITICAL	Critical (DeFi Vaults)	TWAP fallbacks with strict deviation thresholds (max 1.5% delta). Reject same-block rebalance.
SEC-02	Cross-Chain State Desynchronization	CRITICAL	Critical (Bridges & Greenfield)	Deterministic challenge windows and Merkle state proof verification.
SEC-03	Paymaster Drain via Sybil UserOperations	HIGH	High (AA Infrastructure)	Strict Paymaster validation rules, signature nonces, and account-level spend limits.
SEC-04	Reentrancy in Multi-Protocol Yield Routing	HIGH	High (Yield Vaults)	Enforce OpenZeppelin ReentrancyGuardTransient (EIP-1153) across strategy calls.

Consolidated Implementation Roadmap

Phase 1: Foundation & Security Primitives

Months 1–2

Deploy DeterministicCreate2Factory across BSC, opBNB, and Greenfield. Implement core TimeLockGovernance and EmergencyPausable interfaces. Deploy BEP4337PaymasterHub with sponsorship policy plugins.

Phase 2: Shared Protocol & Infrastructure Layer

Months 3–4

Implement and deploy OracleAggregator supporting Chainlink and Pyth TWAP feeds. Deploy VaultFactory4626 and base yield strategy interfaces. Build UniversalBatchVerifier supporting Halo2 and Circom Groth16 ZK proofs.

Phase 3: Domain Modules & Middleware

Months 5–7

Spin up MEV Shield Private RPC daemon endpoints. Deploy Intent Solver relayers and on-chain settlement executors. Deploy Greenfield AI Monetization Gateway and GreenDrive storage services.

Phase 4: Client SDKs & System Integration

Months 8–9

Release @bsc-platform/core-sdk TypeScript library for web and Node.js. Release @bsc-platform/game-sdk Unity C# bindings. Deploy Canonical BSC Indexer and expose Goldsky GraphQL schemas.
