ARC 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.

How XPayr applies it
XPayr records deposit and spend requests separately, binds the intended destination and fee quote, and waits for App Kit events plus destination-chain evidence before marking the operation complete.
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 TestnetSend stablecoins on ARC
App Kit Send transfers a supported token between wallets on the same blockchain. On ARC this can support USDC treasury moves, refunds, reward distribution and direct wallet-to-wallet settlement without a crosschain route.
Verified on ARC TestnetAccept 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.
