# Security #### Security Overview Transit Finance is committed to providing users with secure and reliable aggregation and cross-chain services. A multi-layered security framework is implemented throughout platform design and operation to safeguard user assets and transaction data. #### Non-Custodial Assets Transit does not custody user assets. All trades are executed directly on-chain via smart contracts, and assets remain under the control of the user’s wallet private key. The platform has no ability to access or transfer user funds. #### Smart Contract Security All core smart contracts used by the platform undergo independent third-party security audits and are thoroughly tested prior to deployment to reduce vulnerabilities and attack risks. Audit reports are made public to ensure transparency. #### Transparent Data & Pricing Quotes, liquidity data, and routing calculations are all sourced from public on-chain data. Users can independently verify transactions and outcomes through blockchain explorers, mitigating risks of centralized price manipulation. #### Authorization & Permission Management When trading a token for the first time, users must sign a wallet approval granting the smart contract access to that token. It is recommended to regularly revoke unnecessary approvals via the wallet or authorization management tools after transactions are completed to minimize risks. #### Safe Interaction Tips Transit is only accessible through its official website and verified DApps. The platform will never ask users for private keys, seed phrases, or verification codes. Any unsolicited request for sensitive information via social media or messaging apps is a scam and should be reported and blocked immediately. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
