RISK

Why build_redeem_withdraw_tx is rated Critical

This tool builds a transaction to redeem/claim funds from a tokenized yield vault. Redeeming a withdrawal moves assets (tokens/funds) from the vault back to the user's wallet, which constitutes a financial operation involving the movement of real on-chain assets on Ethereum or Base. Misuse could result in unauthorized redemption of vault assets or loss of funds, warranting critical severity.
