Arbitrum Is Now Live With ETH, USDC, And USDT

We have now added Arbitrum as a live chain in the product, together with the first three Arbitrum assets: ETH, USDC, and USDT.

That gives CryptMeUp another serious EVM payment surface after Base and Polygon, but with its own very clear role. Arbitrum helps us stay close to Ethereum expectations while still keeping the payment experience much more practical than ordinary Ethereum mainnet checkout.

After Base and Polygon, the next EVM step needed to stay pragmatic.

Arbitrum does that. It is widely recognized, heavily integrated into the normal EVM wallet world, and much easier to justify for real payments than jumping straight into expensive mainnet-first settlement. It feels like a chain people already understand, which is exactly what we want for a payment product.

We started Arbitrum with ETH, USDC, and USDT.

That is the right opening set. Native ETH gives us the cleanest direct payment path. USDC and USDT make the chain commercially useful immediately for stable-value checkout expectations. It is not a noisy rollout. It is a practical one.

ETH is the native currency on Arbitrum, so it is the easiest place to begin.

No approval step is needed for native ETH payments. That makes the experience direct, familiar, and fast. For users who already think in ETH but do not want Ethereum mainnet friction on everyday payments, this is exactly the kind of route that makes sense.

USDC and USDT are what make the chain feel practical for merchants instead of merely technical.

If a payer wants to send stable value, or a merchant wants a cleaner mental link to fiat-denominated pricing, these assets immediately lower the friction. That is why they belong in the first Arbitrum release instead of being postponed to a vague later phase.

This was important. Arbitrum should widen the product without forcing users into a different mental model.

Native ETH follows the direct payment route. USDC and USDT follow the same Approve -> Pay token flow already used on the other supported EVM chains. That means the surface expands while the logic stays familiar.

Arbitrum gets its own v1 payment contract, but it follows the same deterministic settlement logic as the other EVM contracts.

The payer sends the total amount. The contract calculates the fee internally. 99.9% goes to the merchant wallet and 0.1% goes to the fee wallet. That keeps the settlement rule visible onchain instead of trusting browser-side math.

A third live EVM chain is not just another chain logo.

It is a real test of whether the product architecture is actually reusable, whether the wallet flow still feels coherent, and whether payment verification continues to hold up when the chain surface grows. That is why this addition matters. It strengthens the product instead of just decorating it.

We still do not want random expansion. We want chain additions that feel earned, practical, and easy to explain.

Arbitrum fits that standard. ETH, USDC, and USDT are a clean first set, and together they give the chain immediate value inside a checkout product. That is exactly the kind of rollout we want more of.
