Arbitrum adopts Paxosā USDG as ecosystem dollar with DeFi support
The regulated stablecoin launches natively on Arbitrum One with backing from Fluid, Morpho, GMX, Maple and Kraken, plus roughly 7 million ARB in incentives
Arbitrum has picked a dollar. Paxos launched USDG, its Global Dollar stablecoin, with native issuance on Arbitrum One on October 6, 2026.
It did not arrive alone. Fluid, Morpho, GMX and Maple integrated it on day one, Kraken lined up exchange support, and roughly 7 million ARB in incentives came along for the ride.
What actually launched
The key word in this rollout is native. USDG is being issued directly on Arbitrum One rather than ported over from another network.
The goal, based on the launch design, is for USDG to serve as a core settlement and liquidity asset across Arbitrum’s DeFi apps. The integrations span lending, perpetual trading and decentralized exchange activity, so the stablecoin is meant to function as collateral and as the unit trades settle in.
GMX is running a launch boost program focused on USDG liquidity pools. The program is expected to deliver APRs of more than 8% on specific USDG-paired pools during the first eight weeks.
On top of that, approximately 7 million ARB has been set aside to encourage use of USDG inside the Arbitrum ecosystem.
The stablecoin behind the launch
USDG is not a newcomer looking for a first home. It had already been deployed on several chains before this Arbitrum expansion.

The token’s circulating supply and market capitalization are estimated at more than $3 billion, with estimates ranging from around $3.1 billion to $3.5 billion.
Paxos backs USDG 1:1 with US dollar cash and equivalents and provides monthly attestations.
USDG operates under oversight from the Monetary Authority of Singapore and under the European Union’s MiCA framework.
The network effect play
USDG sits inside the Global Dollar Network, a group of more than 150 partner organizations. Those partners share in the revenue generated from yields on the stablecoin’s reserves.
Kraken’s involvement gives users a straightforward way to get USDG on and off Arbitrum.
What this means for Arbitrum and DeFi users
For users, the immediate draw is the incentive layer. The 8%-plus APR target on certain GMX pools and the ARB allocation create a window where providing USDG liquidity is being actively subsidized.
The GMX boost is explicitly framed around an eight-week window.
The Global Dollar Network’s revenue-sharing setup gives USDG a distribution advantage that pure token incentives cannot match. ARB rewards are temporary by design, while a share of reserve yield gives partners an ongoing reason to keep promoting the token.
