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.

How XPayr applies it
XPayr turns these primitives into merchant-facing workflows: USDC checkout, direct wallet settlement, immutable fee quotes, memo and batch evidence, App Kit route planning and onchain reconciliation. Verified Testnet behavior is kept separate from review-gated Mainnet execution.
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.
ARC questions answered clearly
What is ARC?: How XPayr applies it
XPayr turns these primitives into merchant-facing workflows: USDC checkout, direct wallet settlement, immutable fee quotes, memo and batch evidence, App Kit route planning and onchain reconciliation. Verified Testnet behavior is kept separate from review-gated Mainnet execution.
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.

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.
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 TestnetBuild on ARC with EVM tools
ARC supports familiar Solidity and EVM tooling such as ethers and viem, but developers must account for ARC-specific behavior including USDC gas precision, native and ERC-20 USDC interfaces, transaction extensions and restricted-transfer reverts.
