Do more with USDC on Arc.

Arc is a Layer-1 blockchain built specifically for stablecoins, designed to support real-world financial activity like payments, FX, and settlement. It uses stablecoins (like USDC) as gas instead of a volatile crypto token, so transaction costs stay low and predictable. InfinitePay is built on top of Arc to let you swap, send, and pay with USDC and other supported stablecoins directly.

Arc is currently live on public testnet — a live but non-production network used for testing before mainnet launch. InfinitePay currently runs on Arc Testnet, which means all balances and transactions here use test tokens, not real funds. Nothing you do in this app currently moves real money.

Arc is designed so that transaction fees are paid directly in USDC, rather than a separate volatile gas token. That means the cost of using InfinitePay stays predictable and dollar-denominated, whether you're swapping, sending, or paying — no surprise fee spikes.

Quotes are live and accurate — pulled in real time so you can see exact rates before committing. Executing a swap currently requires Circle's permissioned StableFX system, which needs signing authority that can't yet be delegated to a self-custody wallet like yours. We're keeping InfinitePay fully non-custodial rather than compromise on that, so live swap execution is coming as soon as this is supported for personal wallets. Every other feature — Send, Receive, Payment Links, Scheduled Payments — is fully live and non-custodial today.

Arc is built for near-instant, deterministic finality — transactions typically settle in under a second. That means when you send, swap, or pay through InfinitePay, the transaction is confirmed and final almost immediately, without waiting on long confirmation times.

No. InfinitePay is non-custodial — you connect your own wallet (MetaMask, WalletConnect, etc.) and every transaction is signed directly by you in your wallet. InfinitePay never holds, stores, or has access to your private keys or funds.
