Proposal: PIP-142: Update the last observed nonce on Arbitrum
Status: Proposed
Author(s): @BoweryKing
Type: Other
Discussions-to: Governance - Paloma
Created: 03/26/2025
Simple Summary
Due to validators failing to attest Skyway Batches that check for nonce increment on Compass on Arbitrum, we must reset the nonce via governance. We expect PIP-140 to resolve this issue with validators being jailed for failing to attest to Skyway nonces on target chains.
Abstract
Due to validators failing to attest Skyway Batches that check for nonce increment on Compass on Arbitrum, we must reset the nonce via governance. This is a proposal to update the lastObservedNonce
height to the most recent height observed in the pending transactions to allow pigeons to relay again on Arbitrum.
Motivation
Updating the lastObservedNonce
data in is required to restart skyway message relaying on Arbitrum.
Technical Specification
We identify the lastObservedNonce
by checking Compass on Arbitrum for the last recorded nonce here:
