Arbitrum has joined the Global Dollar Network, the Paxos-led consortium behind USDG, giving the Ethereum layer-2 a structural claim on reserve income from a stablecoin with more than $3 billion in circulation across networks. USDG launched on Arbitrum on Tuesday, spanning at least nine DeFi integrations.

The initial rollout covers trading, lending and payments infrastructure. Confirmed partners include Morpho, GMX, Fluid, Maple, Li.Fi, Gauntlet, Steakhouse and LayerZero, with Kraken providing on- and off-ramps. Uniswap and Fhenix are next in line.

USDG, issued by Paxos, runs on a distribution model that returns a portion of reserve income to partner networks rather than concentrating yield at the issuer. The Global Dollar Network now counts more than 150 members, including Robinhood, Kraken, Mastercard and OKX.

What is the economic logic for Arbitrum?

Arbitrum currently hosts roughly $3.8 billion in stablecoins, DefiLlama data shows. Circle's USDC accounts for about 60% of that base — and Arbitrum captures none of the reserve yield generated by those tokens.

Joining the Global Dollar Network shifts that arrangement. It grants the foundation a recurring claim on USDG reserve economics flowing through applications on its chain, a revenue stream the DAO can route into incentives, liquidity programs or treasury operations.

"With USDG, Arbitrum and builders across the platform now have a stake in the growth upside," said Brendan Ma, head of investment strategy at the Arbitrum Foundation.

What is the DAO being asked to approve?

A governance proposal published Tuesday asks ArbitrumDAO to designate USDG growth a strategic priority. The measure would allocate 100 million ARB to the foundation's DRIP incentive program and direct treasury assets toward USDG liquidity provision.

Token holders have not yet opened voting. If approved, the 100 million ARB tranche would rank among the foundation's largest direct commitments to a third-party stablecoin.

How does USDG fit into the broader stablecoin map?

USDG's expansion lands as rival alliances lock up distribution. Open Standard has assembled OpenUSD with backing from Mastercard, Visa, Stripe, Coinbase and Shopify. In Europe, Qivalis has drawn 37 banks into a consortium aimed at euro- and dollar-denominated issuance under MiCA.

The shared playbook across these networks: spread issuance economics across payments, exchange and infrastructure partners rather than letting one issuer collect the bulk of reserve yield. Paxos's structure, in market before most of the new entrants, has become the template competitors are racing to replicate.

What else is driving Arbitrum right now?

The network has gained attention since Robinhood agreed to base its planned Robinhood Chain on Arbitrum technology. Robinhood will share a portion of revenue from user activity with the Arbitrum ecosystem under that arrangement.

The USDG alliance extends that logic. Where Robinhood funnels application-level revenue back to the chain, the Global Dollar Network funnels reserve-level revenue. Both attempts push Arbitrum closer to a model where the L2 collects economics from multiple layers of the stack rather than only from sequencer fees.

A binding ArbitrumDAO vote on the governance text is the next step. If the proposal passes, the 100 million ARB tranche would set the foundation's USDG incentive spending and put the chain's reserve-economics model under direct token-holder oversight.
