# Overview

> Move funds between fiat and stablecoins — receive crypto deposits, send withdrawals, and convert currencies through the UQPAY API.

[Stablecoin Account API Publisher Disclaimer](https://developers-sandbox.uqpaytech.com/docs/stablecoin-account/v1.6/guide/stablecoin-account-api-publisher-disclaimer.md)

The Stablecoin Account API lets you hold crypto and fiat balances side by side and move funds between them. You can receive cryptocurrency deposits on dedicated addresses, send withdrawals to whitelisted wallets, and convert between crypto and fiat with real-time quotes — completing the full on-ramp and off-ramp loop. Once converted to fiat, funds can be paid out directly through your UQPAY Global Account's [payout](https://developers-sandbox.uqpaytech.com/docs/global-account/v1.6/guide/payout.md) capability.

## Key capabilities

* **Multi-currency asset wallets** — Hold and query crypto and fiat balances in one account, with available, margin, and frozen balances tracked per currency.
* **Cryptocurrency deposits (on-ramp)** — Generate deposit addresses per asset and network, track incoming deposits, and get notified by webhook as they confirm.
* **Cryptocurrency withdrawals (off-ramp)** — Send funds to address book entries with automatic risk screening, dynamic network fee estimates, and webhook status updates.
* **Currency conversion** — Lock an exchange rate with a quote, then execute crypto–fiat or crypto–crypto conversions at the quoted price.
* **Transfers to Issuance Account** — Move funds from your Stablecoin Account to your Issuance Account.
* **Travel Rule compliance** — Record beneficiary and originator information for third-party and exchange-hosted addresses, backed by VASP, country, and region reference data.
