Aave is preparing to expand its native stablecoin GHO to Arbitrum by deploying a new instance of remoteGSM, a mechanism designed to maintain the asset's peg through decentralized exchange functionality. The proposal, authored by TokenLogic, would allow users to seamlessly swap between stataUSDC and GHO on Arbitrum, mirroring a successful model already deployed on Polygon. This expansion reflects growing demand for GHO across multiple chains and the protocol's confidence in scaling its peg-defense infrastructure beyond Ethereum.
The Gho Stability Module (GSM) has established itself as a capital-efficient tool for both bootstrapping liquidity and defending GHO's dollar peg. The existing remoteGSM deployment on Polygon has reached its 40 million exposure cap and now represents over 13 percent of GHO's circulating supply—a clear indicator that users prefer minting and transacting in stablecoins on their chain of choice rather than bridging from Ethereum. By replicating this proven playbook on Arbitrum, Aave addresses genuine market demand while providing immediate depth to GHO's peg anchor in one of decentralized finance's most active ecosystems. The Arbitrum deployment will launch conservatively with a 20 million cap, allowing the GhoGsmSteward to scale capacity as organic demand justifies expansion, following the same gradual approach that worked on Polygon.
The technical implementation requires several coordinated upgrades. Aave will increase Cross-Chain Interoperability Protocol (CCIP) rate limits across all bridging lanes to accommodate GHO's expanded footprint, with temporary elevation to 155 million between Ethereum and Arbitrum to enable a single 50 million transfer. Once the bridge transfer completes, limits revert to more conservative thresholds—a pattern used successfully during the Polygon expansion. The deployment also includes a new GhoReserve contract that serves as the final destination for unbacked GHO moving across chains, ensuring proper fund custody and accounting as the stablecoin becomes increasingly distributed.
This expansion underscores a broader shift in DeFi infrastructure design: native stablecoin mechanisms are now expected to follow users across fragmented Layer 2 ecosystems rather than funnel all activity back to Ethereum. By giving GHO deep local liquidity on Arbitrum from launch, Aave removes friction for the asset's adoption and signals confidence in its long-term multi-chain strategy. The success of this deployment will likely inform how other protocols approach stablecoin distribution in an increasingly chain-agnostic landscape.
