Arc 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.

How XPayr applies it
XPayr maps a short, non-secret reference to the payment or payout record and verifies the emitted memo event. Private customer data, credentials and secrets must never be placed in public memo content.
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.

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.

Arc 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 MainnetAccept USDC payments on Arc Testnet
Checkout on Arc Testnet 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 MainnetBuild on Arc with EVM tools
Arc supports familiar Solidity and EVM tooling such as ethers and viem, but developers must account for Arc-specific behavior including USDC gas precision, native and ERC-20 USDC interfaces, transaction extensions and restricted-transfer reverts.
