# Introduction

> Accept crypto payments on eight blockchains with one API, and get paid into wallets only you control.

Paywire turns a price in your currency into a crypto payment. You create a **payment link** for an amount such as 25 USD; your customer opens it, picks a coin and network, and pays to a one-time address. Paywire watches the chain, confirms the payment, tells your server with a signed **webhook**, and moves the funds into your MPC wallet.

## What you get

* **One integration, many chains.** Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Tron, Solana and Bitcoin; native coins and stablecoins (USDC, USDT).
* **Fiat pricing.** You charge in USD; the payer sees the exact coin amount, locked for the payment window.
* **A hosted checkout,** or build your own on the same public endpoints.
* **Edge cases handled.** Underpayments, overpayments, late payments and wrong coins follow a policy you control; refunds go back to the payer.
* **Your keys, split.** Funds land in wallets secured by multi-party computation (MPC): no single machine ever holds a whole private key.
