Stablecoin payments on Arbitrum

Arbitrum is a solid, uncomplicated option for stablecoin payments — the sort of network that does not generate interesting problems.

Practical characteristics

Fees are low enough that they stop being a consideration for typical merchant payments. Confirmation is fast enough that price-lock windows are never at risk. Ethereum compatibility means no new wallet. Native USDC removes the bridged-asset question for the most common coin.

Where it sits relative to Base and Polygon

All three are cheap, fast, Ethereum-compatible layer 2s or sidechains, and for a payer the practical differences are small. Gateway support is the deciding factor and it varies: some merchants enable Base and not Arbitrum, others the reverse.

The sensible approach is to hold stablecoins on whichever of these networks your usual merchants support, rather than picking a favourite in the abstract. Moving between them is possible but costs a bridge fee and time you would rather not spend at a checkout.

Where it is accepted, and how (September 2026)

We looked for merchants taking USDC on Arbitrum specifically, and the result is the least merchant-led of any network we have surveyed: Arbitrum is nearly always one option on a gateway’s menu rather than something a merchant chose to advertise.

Merchants that name Arbitrum. RANDHOST publishes a per-coin network table — USDC on Ethereum, BNB Smart Chain, Solana, Polygon, Arbitrum, Base and Optimism — on a proper payments page, which makes it the best-documented Arbitrum route here. REGXA advertises “USDC (Arbitrum)” on a templated landing page with no payment documentation behind it, and its record says so. The gift card platforms Bitrefill, CryptoRefills and Bidali carry it in their network menus, and Genghis names it on its USDC page. (Travala names Arbitrum too, but for USDT; its USDC list does not include it.)

Gateway lists. BitPay, CoinGate, Coinbase Business, NOWPayments and Shopify Payments all publish Arbitrum among their USDC networks. That is how Newegg, Namecheap, Dynadot, airBaltic, AT&T, Vast.ai, Hostinger, Surfshark, Cherry Servers, Prepaid-Host and the Shopify stores come to carry it — the gateway named the network, the merchant did not, and most of those records say “may vary” for that reason.

Who does not. Stripe’s stablecoin checkout lists Ethereum, Base, Polygon and Solana but not Arbitrum. Flexa’s in-person network lists Ethereum, Solana and Avalanche. Confirmo merchants Trezor and Alza pin USDC to Ethereum, and HOSTKEY states Ethereum only despite using BitPay.

What we did not find. An Arbitrum-native consumer merchant. The ecosystem’s commerce activity is in games and trading rather than shops, and the Arbitrum Foundation’s own directories describe protocols, not places to spend. For a payer this changes little — hold USDC on Arbitrum and you can spend it anywhere the gateways above are switched on — but it means the network’s acceptance is borrowed rather than earned, and could narrow if a gateway reorders its menu.

Gas, as always

ETH on Arbitrum, not ETH on mainnet. A few dollars covers a large number of transactions. Most exchanges will withdraw ETH directly to Arbitrum, which avoids bridging.
