๐ŸšจSlowMist TI Alert๐Ÿšจ ๐Ÿ’ธ $OMNI404 Loss: 2.4 WETH ๐Ÿ” Root Cause: In `_transfer()` of OMNI404 (O404), NFT mint/burn counts are derived only from `(balanceOf / units)` integer differences before/after the ERC20 transfer. OMNI404's `transfer(address,uint256)` treats values โ‰ค 50 as ERC721 token IDs, but also transfers a fixed 1e18 OMNI404 units. Uniswap V3 exact-output swaps calling `transfer(recipient, 1/2/.../21)` received 1e18 OMNI404 per call while the pool accounted only wei-level amounts, enabling flash-loan assisted profit. ๐Ÿ“Œ Attacker: 0xfb26db4eab18cb50d29ff431888dd643a7e9c9f8 ๐Ÿ“Œ Victim Pool: 0xb3f613b9bc84ddb29d78fa4685b01d98412bba0b ๐Ÿ“Œ Vulnerable Contract: 0xd5c02bb3e40494d4674778306da43a56138a383e Powered by Tx:
