[MixBytes](https://mixbytes.io/) team was engaged and has verified wstETH deployment on Mantle. Three security researchers checked the presented information according to the internal checklist. The results are as follows: - Mantle network has slightly different features and behavior than Optimism, but these features do not affect wstETH and DAO decision bridging, so presented contracts and architecture can be used without any additional changes to consider. - Deployed contracts match the audited scope. All findings from the reports are addressed in the contracts. - All contracts were correctly deployed and initialized. - The ACL setup was implemented as the NEW contributors requested from the Mantle team without any additional roles and addresses. It is worth noting that the Mantle native explorer works differently than ethescan-like explorers in some cases. For example, to check a multi-sig structure, it is better to use [https://multisig.mantle.xyz/](https://multisig.mantle.xyz/) than native explorer. Also, these contracts [OssifiableProxy](https://explorer.mantle.xyz/address/0x9c46560D6209743968cC24150893631A39AfDe4d/contracts#address-tabs) and [OssifiableProxy](https://explorer.mantle.xyz/address/0x458ed78EB972a369799fb278c0243b25e5242A83/contracts#address-tabs) contain some unnecessary contracts in the deployment verification section. --- _[View the full topic](https://research.lido.fi/t/wsteth-deployment-on-mantle/5991)._
