ARC crosschain recovery
A crosschain USDC transfer should preserve completed approve, burn and attestation steps instead of restarting the entire route after a recoverable failure. App Kit returns step state and transaction evidence that can be persisted and retried safely.

How XPayr applies it
XPayr models bridge and Unified Balance progress as recoverable states, stores step evidence and uses idempotent reconciliation before a retry. A completed source burn is never repeated merely because destination mint confirmation is delayed.
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.

Bridge USDC to and from ARC
ARC App Kit Bridge abstracts the CCTP burn, attestation and mint sequence for supported USDC routes. It is designed to let users move native USDC between ARC, EVM networks and supported non-EVM environments without wrapped-liquidity accounting.
Verified on ARC TestnetARC Unified Balance
Unified Balance combines deposited USDC from supported blockchains into one chain-agnostic balance that can be spent on a destination chain. It reduces the need for a user to manually coordinate each bridge before a payment.
Verified on ARC TestnetARC transaction memos
ARC Memo attaches structured metadata to a contract call and emits an indexed event. Payment IDs, invoice references, payout batches and operational notes can therefore travel with auditable onchain evidence instead of an offchain screenshot.
