Common questions,

Payments settle on Arc in under a second, and they settle with finality, not "probably confirmed, wait twelve blocks." The payer watches it complete while the checkout page is still open. That is the difference between a checkout that feels like Stripe and one that feels like crypto.

Arc mainnet is not live yet, so Leyline runs on Arc testnet today. We are building to be deploy-ready on day one of mainnet rather than starting then. If you want to be among the first links live when it launches, tell us now.

We never hold your money, because we have nowhere to hold it. The payer signs once with their own wallet and the funds move to yours in that same transaction. They pass through a small contract we wrote, the router, which takes its fee and forwards the rest in one step. The router’s balance is zero the instant every transaction ends, and there is a test in the codebase that proves it. That test is the non-custodial claim.

Arc is EVM-compatible, so any Ethereum wallet that can add an Arc network works: MetaMask and anything reachable over WalletConnect, including hardware wallets used through them. The payer needs no account with us and nothing installed beyond the wallet they already have.

0.5% per payment, split off by the router in the same transaction that pays you. The payer covers it on top of your amount, so you receive the full figure you set. On top of that sits Arc’s network fee, typically a fraction of a cent. For comparison, a card processor takes 2.9% + 30¢ and holds the money for days.

You do not need to integrate anything to get paid; create a link and send it. If you want payments inside your own product, the router is a single contract call and the SDK wraps it. The SDK and its documentation ship alongside the testnet beta.

This is the part plain wallet transfers get wrong. If three clients each send you $500, the chain shows you three identical payments and no way to tell them apart. Every Leyline payment carries its link’s ID in the receipt the router emits, so one receipt is one payment is one row in your dashboard, with the payer, the amount, and what it was for.
