Proposed Changes

The following on-chain action(s) execute when the proposal is approved and executed (Ethereum mainnet → destination chain (via LayerZero)):

Action 1 (cross-chain): sendRemoteProposal on GOVERNANCE_OAPP_SENDER (0x1c5D750D18917064915901048cdFb2dB815e0910) — dispatches to the destination chain via LayerZero:

  • swapOwner(address,address,address) on GATEWAY_SAFE 0x5f0F86BcEad6976711C9B131bCa5D30E767fe2bE [gateway]
  • swapOwner(address,address,address) on GATEWAY_SAFE 0x5f0F86BcEad6976711C9B131bCa5D30E767fe2bE [gateway]
  • swapOwner(address,address,address) on GATEWAY_SAFE 0x5f0F86BcEad6976711C9B131bCa5D30E767fe2bE [gateway]
  • swapOwner(address,address,address) on GATEWAY_SAFE 0x5f0F86BcEad6976711C9B131bCa5D30E767fe2bE [gateway]
  • swapOwner(address,address,address) on GATEWAY_SAFE 0x5f0F86BcEad6976711C9B131bCa5D30E767fe2bE [gateway]

Technical Details

  • Network: Ethereum mainnet → destination chain (via LayerZero)
  • Proposal: SETUP-20
  • Proposal plugin: SETUP_MULTISIG 0xBc860b6a4C860C5424B84A056E53ACFb2C99a38F (Aragon OSx Multisig, 3/5)
  • Creation transaction (ProposalCreated): 0xe2badd16c54957d5f38bf1ab56171ef48d7d2bb0f2a3f17e9856c3228336be9b — block 24282586, 2026-01-21
  • Target contract(s):
  • 0x1c5D750D18917064915901048cdFb2dB815e0910 — GOVERNANCE_OAPP_SENDER (ethereum, layerzero_oapp_sender)
  • Addresses verifiable in the protocol-registry.
  • Cross-chain: dispatched via LayerZero from GOVERNANCE_OAPP_SENDER; after Ethereum execution, track delivery on LayerZeroScan using the execution transaction hash.

Other considerations

This proposal contains cross-chain action(s): the effect on the destination chain only lands after the Ethereum execution message is delivered by LayerZero — confirm delivery before assuming the change is live. Independently verify each target address and decoded call against the protocol-registry and the on-chain proposal.
