Build 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.

How XPayr applies it
XPayr validates chain IDs, token decimals, contract bytecode and signed payload boundaries before enabling a route. Developer pages link the Arc primitive to checkout sessions, webhook records and non-custodial wallet execution.
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.

Build on Arc with EVM tools: How XPayr applies it
XPayr validates chain IDs, token decimals, contract bytecode and signed payload boundaries before enabling a route. Developer pages link the Arc primitive to checkout sessions, webhook records and non-custodial wallet execution.
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.

What is Arc Network?
Arc Network is an EVM-compatible Layer 1 built for programmable money. Arc Testnet uses USDC as its native gas token, targets sub-second deterministic finality and integrates Circle infrastructure for payments, liquidity and crosschain movement.
Verified on Arc MainnetArc 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.
Verified on Arc MainnetArc security and opt-in privacy
Arc documents configurable privacy and post-quantum security as evolving parts of its roadmap. Current integrations should distinguish live execution behavior from planned protocol modules and preserve auditability where regulations or operations require it.
