ARC USDC gas fees
ARC pays network gas in USDC instead of a volatile native coin. Its EIP-1559-style fee market uses EWMA smoothing to reduce short-term fee shocks and keep operational costs easier to estimate in dollar terms.

How XPayr applies it
XPayr keeps the chain gas cost separate from its own gateway or operation fee. The public calculator accepts live-style gas inputs, while executable flows obtain a wallet-visible estimate before signing.
Verified on ARC Testnet
XPayr keeps ARC Mainnet payment execution review-gated until canonical production contracts, explorer support and low-value wallet-signed pilots are verified. Public tools and Testnet flows remain available for evaluation.
From question to a controlled ARC transaction
Understand the primitive
Start with the exact ARC capability, supported asset and network boundary instead of a generic blockchain promise.
Plan the route
Choose checkout, send, bridge, swap, Unified Balance, memo, batch or agent settlement and review its fee model.
Sign from the wallet
The merchant or payer wallet signs the operation. XPayr does not treat a browser response as settlement proof.
Verify and reconcile
XPayr checks chain, token, amount, recipient and transaction evidence before updating payment and fee ledgers.

Is this available on ARC Mainnet through XPayr?
XPayr keeps ARC Mainnet payment execution review-gated until canonical production contracts, explorer support and low-value wallet-signed pilots are verified. Public tools and Testnet flows remain available for evaluation.
Does XPayr custody funds or hide the network fee?
No. Wallets sign transactions, chain fees remain visible and XPayr records its operation fee separately. Standard successful checkout uses the configured XPayr gateway fee; advanced ARC operations use their published fee quote.

What is ARC?
ARC is an EVM-compatible Layer 1 built for programmable money. It uses USDC as its native gas token, targets sub-second deterministic finality and integrates Circle infrastructure for payments, liquidity and crosschain movement.
Verified on ARC TestnetARC sub-second deterministic finality
Deterministic finality means a confirmed ARC transaction is not expected to be reorganized later. ARC targets confirmation in under a second, which can shorten payment, payout and agent-job settlement loops.
Verified on ARC TestnetAccept USDC payments on ARC
ARC checkout lets a merchant price and settle in a stable unit while the customer pays from a compatible wallet. Deterministic confirmation, stable gas accounting and programmable contracts make ARC relevant to ecommerce, SaaS and platform payments.
