ARC 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.

How XPayr applies it
XPayr still verifies receipt, chain, token, amount and recipient instead of trusting elapsed time. Fast finality improves the customer experience, while evidence-based reconciliation preserves the accounting boundary.
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.

Accept 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.
Verified on ARC TestnetARC batch transactions and payouts
Multicall3From batches multiple calls while preserving the original sender for each subcall. This supports atomic or partially successful operational batches with a clearer origin than generic relay execution.
Verified on ARC TestnetARC payments for AI agents
ARC’s agentic-economy direction combines onchain identity, reputation and programmable job settlement concepts such as ERC-8004 and ERC-8183. Agents can coordinate work and stablecoin value under explicit policy and budget constraints.
