In this setup, crypto remains under user control and is never held in an exchange account. This page explains the main approaches, their trade-offs, and how Vortex fits architecturally. *** ### Short answer You can sell crypto for EUR without a centralized exchange by: * Initiating the sale from a self-custodial wallet * Swapping assets on-chain using available liquidity * Settling EUR to a bank account (SEPA) via regulated fiat rails The flow does not rely on an exchange balance or custodial trading account. *** ### The four common approaches #### 1. Centralized exchanges (CEX) **How it works:**\ Crypto is deposited to an exchange account, sold internally, and EUR is withdrawn. **Trade-offs:** * Full custody during the process * Account freezes and withdrawal limits * Requires trusting the exchange with funds *** #### 2. Broker-style fiat ramps (MoonPay, Ramp Network) **How it works:**\ A regulated payment provider acts as the principal counterparty.\ They quote a price, buy the crypto from the user, and handle fiat settlement end-to-end via a hosted checkout or widget. Typical examples include MoonPay and Ramp Network. **Trade-offs:** * Very simple UX and broad geographic coverage * Provider controls pricing, spreads, and execution * Limited transparency into liquidity and settlement * Less suitable for custom flows or embedded treasury use This model is not a centralized exchange, but it is broker-led and custodial at the transaction level. *** #### 3. Peer-to-peer (P2P) **How it works:**\ Crypto is sold directly to another party, with EUR transferred manually. **Trade-offs:** * Counterparty risk * Poor liquidity at scale * Operational overhead *** #### 4. Self-custodial off-ramping (non-CEX) **How it works:**\ Crypto stays in the user’s wallet, is swapped on-chain, and EUR is paid out via regulated fiat infrastructure. **Trade-offs:** * Requires compliant fiat settlement * More components than a single broker checkout This is the model Vortex supports. *** ### How selling crypto for EUR works with Vortex Vortex provides a non-custodial off-ramp architecture connecting on-chain liquidity with EUR settlement. **High-level flow:** * User initiates a sell from a self-custodial wallet * Crypto is swapped on-chain using available liquidity * EUR is settled to a bank account via SEPA Unlike broker-style ramps, Vortex does not act as a principal quoting a retail price.\ It connects liquidity and settlement infrastructure without taking custody like an exchange. *** ### What this setup is suitable for * Users who want to avoid exchange custody * Wallet-native applications * Platforms that need EUR payouts without operating a centralized exchange *** ### What it is not * A centralized trading venue * A price-quoting retail broker * A way to bypass regulatory requirements Compliance checks apply where required by law. *** ### Common questions 1. **Can I sell crypto for EUR without KYC?**\ No. EUR bank payouts require compliance checks.\ “Non-custodial” does not mean “unregulated”. 2. **Do I need to create an exchange account?**\ No exchange account is required.\ The flow is wallet-initiated. 3. **Is this available in Europe?**\ Yes. EUR payouts are processed via SEPA where supported. 4. **Is this only for businesses?**\ The same architecture applies to retail users and platforms.\ Integration details differ. *** ### Using the Vortex API If you are building an application and want to integrate crypto-to-EUR off-ramping without running a centralized exchange: * Review the API overview * Check supported flows and compliance requirements * Implement wallet-initiated sell transactions → Proceed to the [API reference](https://api-docs.vortexfinance.co/) to integrate crypto-to-EUR off-ramping --- # Agent Instructions This documentation is published with GitBook.
