Protect your wallet from malicious EIP-7702 delegations. Real-time bytecode analysis warns you before signing dangerous contracts. Testudo protects your Ethereum wallet by analyzing smart contract interactions before you sign them. It intercepts transaction and signature requests in real time, runs bytecode-level analysis, and warns you about dangerous patterns — all before any damage is done. WHAT IT DETECTS - EIP-7702 delegation attacks (auto-drainers, metamorphic contracts) - Malicious token approvals (ERC-20 approve, increaseAllowance) - Dangerous NFT approvals (setApprovalForAll to unknown operators) - Permit signature phishing (EIP-2612, Permit2) - Blind signature risks (personal_sign with suspicious content) - eth_sign abuse (full transaction signing with typed confirmation gate) - Known malicious addresses (real-time threat intelligence lookups) - Suspicious contract deployers (fresh wallets, low nonce) HOW IT WORKS 1. Testudo intercepts wallet requests (eth_sendTransaction, eth_signTypedData_v4, personal_sign, eth_sign) on any webpage. 2. Contract addresses are checked against a threat intelligence database and analyzed for dangerous bytecode patterns (auto-forwarding, DELEGATECALL, SELFDESTRUCT, metamorphic deployment). 3. If a risk is found, a warning modal appears with a clear explanation of what the contract can do. You decide whether to proceed or cancel. 4. Safe interactions pass through without interruption. KEY FEATURES - Pre-signature protection: warnings appear before you sign, not after - Human-readable intent: translates raw contract data into plain English (e.g., "Approve 1,000 USDC to 0xabc...") - Bytecode capability analysis: detects what a contract CAN do, even without source code - Threat intelligence: checks addresses against aggregated malicious address databases - Deployer risk scoring: flags contracts deployed by fresh wallets with no history - Phishing detection: scores personal_sign messages for social engineering patterns - Fail-open design: if analysis fails, your transaction still goes through — Testudo never breaks dApps - No tracking: zero analytics, zero telemetry, zero cookies
