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 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.

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.
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.
