Paxos launched its Global Dollar (USDG) stablecoin natively on Arbitrum One on October 6, 2026, backed by approximately 7 million ARB in ecosystem incentives and day-one integrations from Fluid, Morpho, GMX, Maple and Kraken.

The rollout marks USDG's first native issuance on Arbitrum's main network, rather than a bridged version from another chain. Paxos designed the integration to position USDG as a core settlement and collateral asset across the layer-2's DeFi stack, spanning lending, perpetual futures and spot trading venues.

What integrations came on day one?

Five DeFi protocols and one centralized exchange wired up USDG at launch:

• Fluid and Morpho added USDG lending markets
• GMX ran a launch boost program targeting more than 8% APR on select USDG liquidity pools
• Maple integrated the stablecoin into its credit markets
• Kraken provided on- and off-ramp access between fiat and USDG on Arbitrum

The ARB incentive pool — roughly 7 million tokens — was set aside to subsidize user activity tied to USDG provision and borrowing during the early adoption window.

Why is the GMX boost time-limited?

GMX's launch program runs for an explicit eight-week window. The protocol is offering APRs above 8% on specific USDG-paired pools during that period, creating a defined runway for early liquidity providers before incentives taper.

Beyond GMX, the broader ARB allocation operates as a finite, ecosystem-wide subsidy. ARB rewards are temporary by design and will diminish once the targeted growth metrics are met.

How does USDG's structure differ from typical stablecoins?

USDG is issued under oversight from the Monetary Authority of Singapore and within the European Union's MiCA framework. Paxos backs the token 1:1 with U.S. dollar cash and cash equivalents and publishes monthly attestations.

The stablecoin's circulating supply is estimated between $3 billion and $3.5 billion, with third-party trackers placing the figure closer to $3.1 billion. USDG had already been deployed on multiple chains before the Arbitrum expansion.

What is the Global Dollar Network?

USDG sits inside the Global Dollar Network, a coalition of more than 150 partner organizations that share revenue from yields generated on USDG's reserve assets. The structure gives partner exchanges, wallets and protocols a recurring economic incentive to distribute the token — a model that supplements rather than replaces the one-time ARB incentives.

Kraken's involvement extends this distribution layer by giving users a regulated venue to move dollars into and out of USDG without leaving the Arbitrum ecosystem.

What does this change for Arbitrum users?

For liquidity providers, the 8%-plus APR target on certain GMX pools and the ARB allocation combine into a window where USDG provisioning is being actively subsidized. The economics are front-loaded: the ARB incentives and the GMX boost both follow a defined schedule rather than indefinite accrual.

For the broader Arbitrum DeFi stack, USDG adds a regulated, attestation-backed dollar asset to compete with USDC and USDT for collateral and settlement share across lending and derivatives venues.

The GMX boost concludes in roughly eight weeks. Paxos and its partners will gauge whether the incentive-driven activity converts into structural USDG volume on Arbitrum once the ARB subsidy and yield enhancements expire.
