# What you can build

> How businesses use Rach — from taking a stablecoin payment to running wallets, escrow and payouts for your own customers.

Rach is a set of building blocks. Most businesses start with one and add the
next when they need it. Each recipe below names the products involved and links
to the page that shows the exact calls.

<Info>
  Rach has two APIs with separate keys: **Payments** (gateway, wallets, swap,
  airtime, market data) and **CaaS** (stablecoin accounts and escrow). See
  [Two products, two API keys](/#two-products-two-api-keys).
</Info>

## Accept stablecoin payments

**For:** online stores, SaaS, invoicing, marketplaces taking payment.

Create a checkout per order and send the customer to Rach's hosted page, or
render your own with a deposit address. The customer pays USDT or USDC on any of
[nine networks](/guides/networks); you get a signed `payment.confirmed` webhook
once it is final, and the funds land in your balance.

* [Crypto Payment Gateway](/products/crypto-gateway) — sessions, hosted page, your own UI
* [Webhooks](/guides/webhooks) — `payment.confirmed`
* [Settlement & withdrawals](/guides/settlement-withdrawals) — cash out as crypto or to a bank

## Give every customer a wallet

**For:** exchanges, neobanks, games, loyalty apps — anything where *your* users
hold balances.

Wallet-as-a-Service derives an HD wallet per customer on 13 networks. Rach's
monitor watches every address around the clock and fires a webhook for each
deposit; you send transfers out through the same API.

* [Wallet-as-a-Service](/products/wallet-as-a-service) — wallets, addresses, balances, transfers
* [24/7 Wallet Monitoring](/products/wallet-monitoring) — deposits detected and confirmed
* [Webhooks](/guides/webhooks) — `wallet.deposit.confirmed`, `wallet.transfer.confirmed`

## Move money by phone number

**For:** remittance, payroll, cross-border B2B, super-apps.

CaaS gives each of your users a stablecoin account keyed by phone number. Fund
it, send to anyone by number, and cash out to local fiat — or run pure
non-custodial USDC/USDT wallets.

* [CaaS — Money to any phone](/products/caas)
* [Reliability guide](/guides/caas-reliability) — idempotency, retries, reconciliation

## Hold funds until both sides deliver

**For:** marketplaces, freelance platforms, P2P trading, B2B trade.

Embedded escrow locks a buyer's stablecoins until the deal completes, with
release, refund and dispute resolution built in.

* [Embedded escrow](/guides/embedded-escrow)

## Sell airtime, data, gift cards and bills

**For:** telco resellers, wallets and fintechs adding everyday payments.

One API for mobile top-ups, data bundles, gift cards and utility payments, drawn
from a prepaid balance you fund with stablecoins — at a margin you set.

* [Airtime, Gift Cards & Bills](/products/airtime-giftcards)

## Swap, price and convert

**For:** treasury, trading desks, apps that show live prices.

Same-chain and cross-chain token swaps with quotes and slippage protection, and
top-250 coin prices over REST and a real-time WebSocket.

* [Swap](/products/swap) · [Market Data](/products/market-data)

## Run it as a team

Every product sits in one business workspace: invite teammates with roles
(owner, admin, manager, developer, finance, viewer), create test and live API keys, set
webhook endpoints, and see one dashboard across products.

* [API keys](/guides/api-keys) · [Environments](/guides/environments) · [Errors](/guides/errors)

## See it before you build

with test keys — see [Sandbox & demo](/guides/sandbox-and-demo).
