+# Audit 10 — Post-Audit Fix Review
+
+**Audit Date:** March 24, 2026
+**Commit Range:** `57d4094` (main) to `46f5737` (post-audit)
+**Branch:** `post-audit`
+**Repository:** `https://github.com/LemonTreeTechnologies/olas-lst`
+
+## Objectives
+
+Review of fixes addressing findings from internal audits 8 and 9, applied in the `post-audit` branch.
+Verify that all fixes are correct, complete, and do not introduce new vulnerabilities.
+
+## Scope
+
+5 modified contracts, 2 commits (`40a349c`, `46f5737`):
+
+```
+contracts/l1/Depository.sol                        |   2 +-
+contracts/l1/Distributor.sol                       |   3 +
+contracts/l1/Treasury.sol                          | 109 ++++++++++++------
+contracts/l1/bridging/DefaultDepositProcessorL1.sol|  24 -
+contracts/l2/ExternalStakingDistributor.sol        |  48 ++++-----
+```
+
+## Findings
+
+### Fix 1. Depository: refund sent to `msg.sender` instead of `sender`
+```
+File: contracts/l1/Depository.sol:324
+Before: (bool success,) = msg.sender.call{value: refund}("");
+After:  (bool success,) = sender.call{value: refund}("");
+```
+The `sender` parameter is the original caller passed through from Treasury.
+When called via Treasury (which forwards `msg.sender` as `sender`),
+the refund was incorrectly going to Treasury (`msg.sender`) instead of
+the actual user (`sender`).
+
+**Verdict: Fix correct. ✓**
+
+### Fix 2. Distributor: dangling approval not reset
+```
+File: contracts/l1/Distributor.sol:89
+Added: IToken(olas).approve(lock, 0);
+```
+In the `else` branch (when lock amount is zero and no lock is created),
+a prior `approve(lock, olasAmount)` at line 79 leaves a non-zero allowance
+on the Lock contract. The fix resets approval to zero.
+
+**Verdict: Fix correct. ✓**
+
+### Fix 3. Treasury: ETH value not forwarded to bridge calls during unstake
+```
+File: contracts/l1/Treasury.sol:142-213
+Refactored into: _processUnstakes() internal function
+```
+The original `requestToWithdraw()` called `unstakeExternal()` and `unstake()`
+without forwarding `msg.value` for bridge gas payments. Bridge calls on Gnosis
+(AMB), Optimism (L1CrossDomainMessenger), etc. require native ETH for gas.
+ETH sent by the user would remain stuck in Treasury.
+
+The fix:
+- Extracts `_processUnstakes()` helper (also resolves stack-too-deep)
+- Tracks `remainingValue` across external and LST unstake calls
+- Validates `externalAmounts.length == values[0].length`
+- Forwards `{value: externalValue}` to `unstakeExternal()` and `{value: remainingValue}` to `unstake()`
+- Rejects leftover ETH when no unstaking needed (`if (msg.value > 0) revert`)
+
+**Verdict: Fix correct and complete. ✓**
+
+### Fix 4. DefaultDepositProcessorL1: `drain()` function removed
+```
+File: contracts/l1/bridging/DefaultDepositProcessorL1.sol
+Removed: function drain() external { ... }  (24 lines)
+```
+The `drain()` function allowed the owner to withdraw all native balance
+from the deposit processor. Removed to reduce attack surface — leftover
+refunds are handled via the existing `LeftoversRefunded` event path.
+
+**Verdict: Fix correct. ✓**
+
+### Fix 5a. ExternalStakingDistributor: guard checks moved inside service unstake condition
+```
+File: contracts/l2/ExternalStakingDistributor.sol:684-710
+```
+Previously, `availableRewards` and `stakingState` were read from `stakingProxy`
+even when no service unstake was requested (`stakingProxy == address(0)` or
+`serviceId == 0`). This caused reverts on invalid proxy addresses.
+
+The fix moves all staking proxy reads inside the
+`if (stakingProxy != address(0) && serviceId > 0)` block.
+
+**Verdict: Fix correct. ✓**
+
+### Fix 5b. ExternalStakingDistributor: curating agent access control per-service
+```
+File: contracts/l2/ExternalStakingDistributor.sol:803
+Before: mapCuratingAgents[msg.sender]
+After:  mapServiceIdCuratingAgents[serviceId] == msg.sender
+```
+Previously, any address in the generic `mapCuratingAgents` mapping could act
+on ANY service. The fix restricts to per-service curating agents via
+`mapServiceIdCuratingAgents[serviceId]`.
+
+**Verdict: Fix correct. Addresses cross-service privilege escalation. ✓**
+
+### Fix 5c. ExternalStakingDistributor: `stakingHash` computation moved outside loop
+```
+File: contracts/l2/ExternalStakingDistributor.sol:939
+```
+`keccak256(abi.encode(stakingGuard, stakingProxy))` was computed inside a loop
+traversing curating agents. Since the inputs don't change per iteration,
+this is a gas optimization only.
+
+**Verdict: Fix correct (gas optimization). ✓**
+
+## Summary
+
+| # | Contract | Fix | Severity | Correct? |
+|---|----------|-----|:--------:|:--------:|
+| 1 | Depository | msg.sender → sender refund | Low | ✓ |
+| 2 | Distributor | Reset dangling approval | Low | ✓ |
+| 3 | Treasury | ETH value forwarding + validation | Medium | ✓ |
+| 4 | DefaultDepositProcessorL1 | Remove drain() | Low | ✓ |
+| 5a | ExternalStakingDistributor | Guards inside condition | Low | ✓ |
