summary: Vault Exit Lawyer
description: 'Before moving treasury funds out of an ERC-4626 or ERC-7540 vault: reads the chain at one pinned block and returns how much can exit now, the haircut vs convertToAssets, partial-exit maximum, liquidity coverage, queue/cooldown timing, admin-power flags (upgrade, pause, multisig threshold, timelock), and a verdict EXIT_NOW_FULL / EXIT_PARTIAL / QUEUED / BLOCKED / UNKNOWN. With a holder it simulates redeem via eth_call. Optional docsUrls are checked against the contract for contradictions. All numbers are computed deterministically; the model only reads documentation. Answers in seconds to about a minute; if a data source stalls it returns a signed partial result (partial, missing) that names what was not read instead of timing out. Not financial advice.
Price: 0.25 USDC on Base (x402).'
