Title: [ARFC] Launch GHO on Linea & Set ACI as Emissions Manager for Rewards
Author: TokenLogic
Created: 2025-08-18

Summary

This publication proposes deploying GHO on the Linea blockchain and appointing ACI as the Emissions Manager for both GHO and aGHO. The goal is to position GHO as the dominating decentralized stablecoin within Linea’s ecosystem.

Motivation

Linea is a high-performance, EVM-equivalent zk-rollup developed by ConsenSys, offering ultra-low fees, fast finality, and deep integration with Ethereum infrastructure such as Infura and MetaMask.

Aave V3 has already launched on Linea, enabling increased DeFi adoption and liquidity flow. Linea is now launching Native Yield, an innovative mechanism that auto-stakes bridged ETH via Lido v3 stVaults, channeling staking rewards into DeFi liquidity incentives on Linea.

Deploying GHO on Linea in concert with these momentum initiatives ensures GHO becomes a foundational stablecoin, enabling synergies with liquidity programs, boosting peg stability, and expanding GHO’s on-chain utility.
