feat(v1_5_0): add OnRamp fee sweep changesets with WETH auto-unwrap#1825
Conversation
Add CLD changesets for sweeping accumulated fees from EVM2EVMOnRamp v1.5.0
contracts to a validated treasury address via MCMS proposals.
Changesets:
- sweep_all_onramps_v150_evm: Mega flow that discovers all v1.5.0 OnRamps
on a chain and sweeps LINK + non-LINK fees in one atomic MCMS batch
- configure_fee_sweep_v150_evm: Sets treasury as sole NOP with 100% weight
- sweep_link_fees_v150_evm: Sweeps accumulated LINK via payNops
- sweep_non_link_fees_v150_evm: Withdraws non-LINK fee tokens to treasury
Key features:
- Atomic WETH unwrap: When fee token is WETH, generates 3-step flow
(withdraw → unwrap → native transfer) in a single MCMS batch
- Treasury allowlist: Change-controlled per-chain approved recipients
reject proposals targeting unauthorized addresses
- Defensive NOP re-assertion: Mega flow always sets NOPs in the batch
to guard against concurrent proposal interference
- Auto-discovery: Resolves OnRamps, WETH9, and RBACTimelock from datastore
Operations: setNops, payNops, withdrawNonLinkFees (OnRamp), withdraw (WETH)
Sequences: configure-fee-sweep, sweep-link-fees, sweep-non-link-fees,
sweep-all-onramps
