Hey-hey,

Thank you for participating in the RFP call for the [wstETH on BNB](https://research.lido.fi/t/rfp-wsteth-on-bnb/5988). I admire seeing a joint response of two well-known, established teams.

As for me, this proposal is well-shaped and neatly crafted to continue discussion and further considerations.

I have some questions here about the proposed solution, sorry if some of them are not applicable:

- Do you consider charging the bridging fees according to the [native gas currency expectations](https://research.lido.fi/t/unofficial-guidelines-for-bridging-solutions-network-expansion-workgroup/5790/4) and what are they?
- Would it be possible to introduce an ability for emergency pauses on behalf of the established Emergency Breaks msigs together with the implementation of the DAO Governance forwarder?
- Have you regarded previously shipped cross-chain governance architecture developments (e.g., AAVE’s [a.DI](https://github.com/bgd-labs/aave-delivery-infrastructure/)) for the design presented?
- Could you shed some light on the token standards the proposed representation would have implemented? (e.g.: ERC-[2612](https://eips.ethereum.org/EIPS/eip-2612)/[1271](https://eips.ethereum.org/EIPS/eip-1271) or emerging anticipated ones like [xERC-20](https://github.com/connext/EIPs/blob/master/EIPS/eip-7281.md))
- Would it be possible to pass additional calldata items together with token bridging requests for future extensions/integrations and UX improvements?

Thank you once again for the very tempting opportunity!
