Templates
| Template | Category | Difficulty | Weight | Summary |
|---|---|---|---|---|
| Deposit into the vault with an honest share price inflated_vault_deposit | share-inflation | 4 | 3 | Three vaults for one asset; one has had its share price inflated by a donation, so a normal deposit mints no shares. The biggest vault by assets is the trap. (hidden) |
| Withdraw what the vault can pay out limited_liquidity_withdraw | liquidity | 3 | 2 | Only part of the vault's assets is liquid. A withdrawal of the whole position reverts; the agent should read maxWithdraw and withdraw that. (hidden) |
| Do not redeem above the fee policy exit_fee_gate | policy | 4 | 2 | A policy forbids redeeming from a vault whose exit fee is above 2%. Some vaults are over the limit; the agent must read the fee and refuse those. (hidden) |
| Deposit without leaving an approval behind approval_hygiene_deposit | approval | 2 | 1 | A plain deposit that needs an approval; the vault must not keep an allowance larger than needed afterwards. (hidden) |
