What is Arc Network?
Arc Network is an EVM-compatible Layer 1 built for programmable money. Arc Testnet 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 Arc Testnet workflows: USDC checkout, direct wallet settlement, immutable fee quotes, memo and batch evidence, App Kit route planning and onchain reconciliation. Arc Mainnet is not currently supported for public or production execution.
Verified on Arc Mainnet
Yes. Arc Network has officially launched its Mainnet (Chain ID: 5042). XPayr supports live non-custodial checkout, verified routes, canonical Circle CCTP, Unified Balance and explorer reconciliation on Arc Mainnet alongside continued testnet access.
From merchant intent to a verified Arc transaction
Understand the primitive
Start with the exact Arc Network capability, supported asset and execution 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?
Yes. Arc Network has officially launched its Mainnet (Chain ID: 5042). XPayr supports live non-custodial checkout, verified routes, canonical Circle CCTP, Unified Balance and explorer reconciliation on Arc Mainnet alongside continued testnet access.
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 App Kit operations use their published fee quote.

USDC gas fees on Arc Testnet
Arc Testnet 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 MainnetArc Testnet 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 MainnetBuild 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.
