Smart Account Session Key Risk Explainer

WHAT IT DOES

Smart Account Session Key Risk Explainer analyzes the risks of a session key before you approve it for your smart account. The tool reads the session key's permissions from the contract — including which target contracts it can call, which functions it can execute, what spending limits apply, and how long the key is valid. It detects concerning patterns like unlimited spending limits, very long expiry times, broad target access, permission to upgrade contracts, and selfdestruct opcodes. The tool then uses AI to generate a plain-language explanation of the session key risks: what the session key can do, how long it is valid, what permissions it has, and whether you should approve it. Results include a risk level, session key address, status, validity period, spending limit, allowed targets, allowed functions, upgrade capability, flags, and a comprehensive AI-generated explanation. The tool operates entirely read-only — no transactions are sent, no signatures are required. The AI assessment is designed to help you understand exactly what permissions you are granting before you approve a session key.

HOW TO USE

Connect your EVM wallet using the "Connect" button in the header. Select the network where the smart account is deployed from the dropdown menu. Enter your smart account address. Enter the session key address you are evaluating. Click "Analyze session key risk" to begin the analysis. The tool reads the session key permissions from the contract, detects risk patterns, and sends the data to the AI for a plain-English risk explanation. Results appear within seconds, showing the smart account address, session key address, chain, risk level, status, validity period, spending limit, allowed targets, allowed functions, upgrade capability, flags, and a comprehensive AI-generated explanation written in clear, conversational language.

SESSION KEY PERMISSION DETECTION AND RISK SCORING

The tool uses a pattern-based approach to detect session key permissions from the contract bytecode. It scans for keywords and patterns including "session", "key", "module", "unlimited", "max", "any", "target", "function", "selector", "upgrade", "implementation", and "selfdestruct". The expiry period is estimated based on contract patterns (7-365 days), with typical session keys valid for 30-90 days. Spending limits are classified as "Unlimited" (high risk), "Limited" (moderate), or "Unknown". Target scope is classified as "Any target" (high risk), "Specific contracts" (moderate), or "Unknown". Function scope is classified as "Any function" (high risk), "Specific functions" (moderate), or "Unknown". The tool also detects upgrade capability and selfdestruct opcodes. The risk score is calculated based on: unlimited spending (2 points), unlimited targets (2 points), upgrade capability (3 points), expiry over 180 days (1 point), and expiry over 90 days (0.5 points). The AI receives all this data and is prompted to explain the session key risks in plain language — stating what the session key can do, which contracts it can call, which functions it can execute, what spending limits apply, and how long the key is valid. The AI is also instructed to state plainly what it cannot verify — that it reads on-chain permissions and configuration, not the key's actual use, off-chain security of the key, or future transactions that may be submitted with this key.

WHAT IT CANNOT SEE

This tool cannot definitively verify that a session key is safe — only reads its permissions and configuration. It cannot detect off-chain key compromise or malicious use of a valid session key — a session key with legitimate permissions could be stolen and abused off-chain. The tool cannot predict future transaction patterns that might abuse the session key — it can only analyze the permissions granted, not how the key will be used. Legitimate session keys with broad permissions may be used safely in controlled environments — broad permissions are not necessarily a risk if used responsibly. Session key permissions can be changed or revoked after creation — the current configuration may not reflect future changes. The tool cannot detect if the session key has been compromised. The tool cannot detect if the smart account has been compromised. The tool cannot detect if the session key is being used in an unexpected way. The tool cannot predict the future behavior of the session key holder. The tool cannot verify the legitimacy of the target contracts.

PLEASE NOTE

Smart Account Session Key Risk Explainer supports EVM-compatible chains only (Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche, and others). The tool is read-only and never requests wallet signatures or transaction approvals. Session key risk assessments are AI-generated from on-chain data and estimated metrics — always verify session key permissions through the smart account's official interface and your wallet's transaction preview before approving. The AI assessment is for informational purposes only and does not constitute financial or legal advice. Never approve a session key with permissions you do not fully understand. Always set reasonable expiry times and spending limits for session keys.
