Arbitrum vs Base for Payments: Which Layer 2 Should You Settle On?

Arbitrum and Base are both excellent Ethereum Layer 2 networks, both settle USDC for a fraction of a cent, and either would beat card rails on cost. So for a payments business the question is not "which is good" — both are — but which is the better default to settle on. This is our honest take, and why Furlpay chose Arbitrum.

Where they are the same

Both are optimistic rollups securing to Ethereum, both have native Circle-issued USDC, and both offer sub-cent gas and fast confirmation. For most integrations the developer experience is similar, and Circle's CCTP lets USDC move between them. If your customers or partners are already on Base — for example, deep in the Coinbase ecosystem — settling on Base is entirely reasonable.

Why Furlpay defaults to Arbitrum

• Institutional volume already lives there: Mastercard runs 24/7 stablecoin settlement on Arbitrum, and Robinhood built its chain on Arbitrum Orbit.
• Mature Orbit ecosystem: a clear path to an app-specific chain later without changing rails.
• Consistently low, predictable fees for high-frequency payment and agent workloads.

None of this makes Base a bad choice — it is a strong network with a large ecosystem. It is a question of defaults, and for a payments and settlement product the institutional gravity around Arbitrum tipped it for us. We go deeper on the rail itself in USDC on Arbitrum.

The practical answer

Settle where your money and counterparties already are, and where fees are predictably tiny. For most businesses accepting stablecoin payments in 2026, that is Arbitrum — but Base is a close, legitimate second, and multi-chain via CCTP means you are not locked in either way.

Both chains make the gas cost a rounding error. So pick on ecosystem and finality, not on a tenth of a cent — and settle where the institutions already do.
