[ARM] Deploy 038 WETH ARM on mainnet

[clement-ux]

Description

Record the mainnet deployment of the WETH ARM: a WETH-quoted MultiAssetARM with four Lido/EtherFi base assets, each wired through its own redemption adapter behind a newly deployed proxy:

• stETH — pegged 1:1 to WETH, redeemed through the Lido withdrawal queue.
• wstETH — non-pegged Lido wrapper, unwrapped and redeemed through the Lido withdrawal queue.
• eETH — pegged 1:1 to WETH, redeemed through the EtherFi withdrawal queue.
• weETH — non-pegged EtherFi wrapper, unwrapped and redeemed through the EtherFi withdrawal queue.

Ownership of the ARM, its CapManager, and all four adapter proxies is handed directly to the mainnet 2/8 multisig (MULTISIG_2_OF_8). The operational role is the Talos KMS relayer (ARM_TALOS_RELAYER). No lending market is wired up; idle WETH remains in the ARM until a market is added in a follow-up deployment.

This deployment supersedes the legacy ETH ARM deployed by 036_DeployMultiAssetARMScript. The legacy resolver entries and execution history remain recorded, while the old deployment script is explicitly skipped.

The companion USDC-quoted ARM deployed in the same round is recorded in #315.

The following PRs are included in this deployment:

• Block deposits at the asset floor when live LPs exist #311
• Set price support for exact prices and remaining liquidity #312

All four assets start with buyAmount = 0 and sellAmount = 0; trading remains disabled until the operator sets swap limits with setPrices().

Governance

There is no GovernorSix proposal. Ownership of the ARM, CapManager, and all adapter proxies was transferred directly to the mainnet 2/8 multisig during deployment. The proxy implementations and admins have been confirmed on-chain, so 038_DeployWETHARMScript is recorded with proposalId: 1 and tsGovernance: 1.

Post-deployment follow-ups (operator)

• Enable trading. buyAmount and sellAmount are 0 for every base asset. Talos must set the intended swap limits through setPrices() before swaps are enabled.

Tests

• forge build
• forge test --match-contract Fork_WETHARM_Smoke_Test --fork-url "$MAINNET_URL" -vv — 2/2 tests passed.
• Confirmed on-chain that the ARM, CapManager, and all four adapter proxies point to the implementations recorded above and are administered by the mainnet 2/8 multisig.

[naddison36]

All 12 contract addresses match across:

• The PR description’s Contracts table
• build/deployments-1.json
• The PR description’s Contract diff commands

Verified:

• All six proxies point to the recorded implementations.
• Every proxy admin is the mainnet 2/8 multisig.
• All implementations and proxy bytecode match repository source.
• Mainnet-fork smoke tests pass: 2/2.
• Resolver JSON is valid and deployment timestamp is plausible.
• ARM ownership, operator, fees, caps, assets, adapters, pricing, and disabled initial liquidity match the deployment script.
• All deployed implementation constructor parameters match 038_DeployWETHARMScript.
