Direct answer

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 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

1

Understand the primitive

Start with the exact Arc Network capability, supported asset and execution boundary instead of a generic blockchain promise.

2

Plan the route

Choose checkout, send, bridge, swap, Unified Balance, memo, batch or agent settlement and review its fee model.

3

Sign from the wallet

The merchant or payer wallet signs the operation. XPayr does not treat a browser response as settlement proof.

4

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.
