Proposal: PIP-139: Update last observed nonce on Ethereum

Status: Proposed

Author(s): @BoweryKing

Type: Other

Discussions-to: Governance - Paloma

Created: 03/26/2025

Simple Summary

Validators are not attesting to observations on target chains. This means that nonces are out of sync on Ethereum. We must recover nonces with a vote to sync.

Abstract

Minting/burning transactions to be stuck on Ethereum. 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 Ethereum.

Motivation

Updating the lastObservedNonce data in is required to restart skyway message relaying.

Technical Specification

Chain New Nonce
Ethereum 404
