Paxos brought its USDG token to the Arbitrum stablecoin market on 6 October, with the Arbitrum Foundation joining the Global Dollar Network and integrations lined up across Fluid, Morpho, GMX, Maple, Li.Fi, Gauntlet, Steakhouse, LayerZero and Kraken. Uniswap and Fhenix are listed as coming later.
The announcement reached outlets as a press note rather than a Paxos release, and the Arbitrum stablecoin supply has yet to show any of it. DefiLlama put USDG at $3.083bn in circulation on the day of the launch, spread across six chains, with Arbitrum absent from the breakdown entirely. That ranks it seventh among dollar tokens in a $307.575bn stablecoin market, behind USDT at $184.156bn, USDC at $74.325bn and four others.

Almost half the token lives on one chain. X Layer carries $1,424m, or 46.2% of supply, ahead of Robinhood Chain at $718m and Solana at $619m. Ethereum, the network Arbitrum settles to, holds $257m, which is 8.3%. Ink and Hyperliquid account for the remaining $65m between them. No Arbitrum stablecoin balance is recorded against the token at all.
Nothing about a launch-day balance of zero is unusual, since supply has to be minted or bridged before it registers. It does mean the $3bn in the headline figure belongs to other chains, and that the Arbitrum stablecoin footprint of USDG starts from scratch against incumbents with years of liquidity behind them.
What Arbitrum Gets Is a Share of Reserve Income
The Global Dollar Network distributes reserve earnings to the partners that drive adoption instead of keeping them with the issuer, which is the mechanism that makes this more than a listing. Brendan Ma, head of investment strategy at the Arbitrum Foundation, framed the appeal in those terms, saying that “with USDG, Arbitrum and builders across the platform now have a stake in the growth upside.”
Neither party has published Arbitrum’s percentage share. Paxos says the network has more than 150 partners, so the pool is wide, and the revenue depends on an Arbitrum stablecoin balance that does not exist yet.
One detail of the issuance structure is worth keeping straight. USDG is issued by Paxos Digital Singapore and regulated under the Monetary Authority of Singapore, so the US charters the group has won elsewhere, including its OCC trust conversion in December 2025, sit beside this token rather than behind it. DefiLlama also records no audits against USDG. Reserve economics of this kind have become the competitive lever in a market where regulators are writing the rules for issuers and new dollar tokens arrive almost weekly, from AllUnity in Europe to U.S. Bank on Stellar.
Investor Takeaway
USDG had $3.083bn outstanding across six chains on 6 October and none of it on Arbitrum, so the token’s balance there begins at zero.
The 100 Million ARB Is Still a Proposal
A plan to add 100 million ARB to the DeFi Renaissance Incentive Program is attached to the launch, and it has not been approved. DRIP was brought by Entropy and funded with 80 million ARB across its first four seasons, capped at 20 million per season, under a non-constitutional AIP that runs to 1 July 2026.
The proposed top-up would therefore exceed the entire original program by 25%. Until the DAO votes, the incentive behind the Arbitrum stablecoin push is a request rather than a budget, and that distinction is worth holding on to when the number appears in coverage without it.
USDC Holds 61.58% of the Arbitrum Stablecoin Market
Arbitrum carries $3.78bn in stablecoins, up 2.89% over seven days, with USDC at 61.58% of the total, or roughly $2,328m. Everything else shares the remaining $1,452m. Cointelegraph put the chain’s total near $4bn, slightly above what DefiLlama shows.

Source: DefiLlama · Chart: FinanceFeedsUSDG is entering a market where one issuer holds three fifths of the Arbitrum stablecoin base and carries the strongest depeg-risk rating of the major dollar tokens. Displacing that share of the Arbitrum stablecoin pool takes either yield that USDC does not pay or distribution that USDC does not have, which is what the reserve-sharing model and the proposed ARB incentives are meant to supply. Whether they do will be legible within weeks in the chain data, now that stablecoin flows are tracked hourly.
Investor Takeaway
The 100 million ARB proposed for DRIP would exceed the 80 million that funded the program’s first four seasons, and the DAO has not voted on it.
