# Merchants

> Accept payment in any asset and settle in your preferred token.

Payment and commerce products integrate Mayan so a buyer can pay in whatever asset they hold while the business settles in one. The conversion happens in transit, and neither side interacts with a swap.

## What integrating with Mayan unlocks

* **Accept anything, settle in one token.** A customer pays 0.16 ETH on Ethereum, and you receive 250 USDC. They never see a swap, and you never handle a token you did not ask for.
* **A price that holds.** On eligible routes the output is locked before the swap executes, so the amount you display is the amount that arrives. See [Guaranteed Price](/features/guaranteed-price) for which ones qualify.
* **Instant settlement.** Payments land in seconds.
* **Fixed addresses for repeat payers.** They send funds like an ordinary transfer, without connecting a wallet or signing. See [deposit addresses](/features/deposit-addresses).

## Use cases

* [Pay](/use-cases/pay): stablecoin settlement where the amount matters
* [Deposit & Withdraw](/use-cases/deposit): funding and payouts

## Case studies

* **MoonPay** converts onramps to any token instantly with Mayan.
* [**PrimeVault**](https://mayan.finance/blog/mayan-unlocks-native-cross-chain-transfers-for-institutions-on-primevault) manages stablecoin treasury operations across any chain with Mayan.
