wstETH Deployment on Scroll

Proposals Lido on L2
7

A working group of the Lido on Ethereum protocol contributors (@arwer13, @TheDZhon) has evaluated the current proposal and ended up with the following:

  • The proposed contracts adhere to the established design of the wstETH token on Layer 2 solutions described in depth in the wstETH rollup bridging guide
  • The deployments are in full correspondence with the presented audit, source code, and bytecode wise, with no significant issues found
  • All configurations and parameters are relevant and meet expectations.
  • The access control list (ACL) configuration appears reasonable regarding the Lido DAO ownership and usage of the Emergency Breaks setup for both L1 and L2 counterparts .

NB: It’s suggested that the proxy admin instances be passed to the Lido DAO on condition of the successful snapshot vote run.

Pre-vote ACL and levers setup:

  • for ScrollBridgeExecuror

  • A bridge admin and role holder on L1 is the Lido DAO Agent

    • owner for L1LidoGateway
    • WITHDRAWALS_DISABLER_ROLE for L1LidoGateway
    • WITHDRAWALS_ENABLER_ROLE for L1LidoGateway
    • DEPOSITS_DISABLER_ROLE for L1LidoGateway
    • DEPOSITS_ENABLER_ROLE for L1LidoGateway

  • A bridge admin and role holder on L2 is the ScrollBridgeExecutor

    • owner for L2LidoGateway
    • WITHDRAWALS_DISABLER_ROLE for L2LidoGateway
    • WITHDRAWALS_ENABLER_ROLE for L2LidoGateway
    • DEPOSITS_DISABLER_ROLE for L2LidoGateway
    • DEPOSITS_ENABLER_ROLE for L2LidoGateway

  • Emergency breaks msig on L1 is 0x73b047fe6337183A454c5217241D780a932777bD , 3/5 threshold:

    • WITHDRAWALS_DISABLER_ROLE for L1LidoGateway
    • DEPOSITS_DISABLER_ROLE for L1LidoGateway

  • Emergency breaks msig on L2 is a new one 0xF580753E334687C0d6b88EF563a258f048384Ee6 inheriting the same EOAs as for L1, 3/5 threshold:

    • WITHDRAWALS_DISABLER_ROLE for L2LidoGateway
    • DEPOSITS_DISABLER_ROLE for L2LidoGateway

:next_track_button: Post-vote (if the vote is supported) finalizing actions from the Scroll side:

We suggest that Lido DAO take this proposal favorably, which would enhance the presence of wstETH in one of the most up-and-coming L2 solutions.
