Attestara

Attestara is an institutional-grade compliance proxy designed for Permissioned DeFi (like Aave Arc). It acts as a middleware layer that enforces strict AML (Anti-Money Laundering) and KYC (Know Your Customer) checks before any user can interact with a smart contract, but without ever putting Personally Identifiable Information (PII) on the blockchain.

1. Off-chain Screening: A user (or institution) requests to deposit into a Vault. The Compliance & Routing Engine (CRE) intercepts this intent and screens the wallet against Chainalysis, Etherscan, and an AI Oracle (Gemini).
   2.Attestation & Signatures: If cleared, the CRE signs an EIP-712 "Compliance Attestation." This attestation contains only a hashed commitment of the AML report, not the actual data.
2. Simulation (Tenderly): The CRE runs a pre-flight simulation against a Tenderly Virtual TestNet to ensure the transaction will succeed, preventing wasted gas.
3. Execution: The transaction is relayed on-chain. The PermissionedVault smart contract instantly verifies the CRE's cryptographic signature and the user's Decentralized Identifier (DID) before accepting the deposit.
   What problem it solves:
   Institutions want to participate in DeFi but cannot legally interact with sanctioned entities or anonymous mixers (like Tornado Cash). Currently, "Permissioned DeFi" relies on centralized whitelists. Attestara decentralizes this by using a real-time, per-transaction attestation firewall. It guarantees compliance (preventing illicit funds) while preserving privacy (no personal data on-chain).
