Purchasing 0x (ZRX) has never been easier, especially with flexible payment options like credit card and SEPA bank transfer. Whether you're a beginner exploring decentralized finance (DeFi) or an experienced investor diversifying your portfolio, understanding how to securely buy and manage ZRX is essential. This guide walks you through everything you need to know—from storage and payment methods to the technology behind 0x and its long-term potential.
How to Store ZRX Safely
Once you’ve purchased ZRX tokens, secure storage is crucial. One reliable option is using a dedicated crypto vault that supports ZRX. These vaults offer organized, secure environments where you can not only store but also buy, sell, and swap ZRX for other cryptocurrencies seamlessly.
Alternatively, you can transfer your ZRX to a private wallet by providing your wallet address during purchase. For enhanced security, many platforms use cold storage solutions, keeping the majority of funds offline and protected from cyber threats. This ensures your assets remain safe while still allowing quick access for trading.

Can You Buy ZRX with PayPal?
Yes, you can buy ZRX with PayPal through select crypto platforms. Alongside PayPal, popular payment methods include:
- Credit/debit cards (Visa, Mastercard)
- SEPA bank transfers
- iDeal
- SOFORT
- EPS bank transfer
PayPal stands out for its speed and convenience—transactions are processed in moments without repeatedly entering bank details. As a globally trusted payment solution with over 25 years of operation, it offers peace of mind when purchasing digital assets like ZRX.
However, while PayPal allows you to buy ZRX, it does not support direct deposits of ZRX into your PayPal wallet. Once purchased, your tokens must be sent to a compatible crypto wallet or vault.
Fractional Purchases: Buy Less Than 1 ZRX
You don’t need to buy a whole ZRX token. Just like Bitcoin, ZRX is divisible, allowing you to invest small amounts—such as 0.1 or even 0.01 ZRX. Some platforms let you start trading with as little as €10, making it accessible for all types of investors.
This flexibility lowers the entry barrier and enables dollar-cost averaging strategies, helping you build your position over time without large upfront investments.
Is Buying ZRX Safe?
Reputable platforms prioritize security and compliance, making it safe to buy ZRX. Look for exchanges or brokers that:
- Use advanced encryption and cold storage
- Are officially licensed (e.g., by BaFin in Germany)
- Offer multi-factor authentication (MFA)
These measures protect your funds and personal information, ensuring a trustworthy buying experience.
Is ZRX Legal in Europe?
Yes, ZRX is fully legal in Europe. There are no restrictions on buying, holding, or trading 0x tokens across EU countries. Regulatory frameworks continue to evolve, but cryptocurrencies like ZRX operate within compliant boundaries on licensed platforms.
Tax Implications of Holding ZRX in Germany
Germany offers one of the most crypto-friendly tax environments globally:
- Holding ZRX for more than one year? Sales are completely tax-free.
- Short-term gains under €600 annually? Also exempt from taxation.
- Only profits exceeding €600 in short-term capital gains or income from staking/lending are taxable.
Always keep accurate records of your transactions to ensure compliance during tax season.
Do You Need ID to Buy ZRX?
Most regulated platforms require KYC (Know Your Customer) verification. This means submitting identification documents before purchasing ZRX. While this removes anonymity, it enhances platform security and aligns with anti-money laundering (AML) regulations.
Business accounts are also supported—simply select this option during registration to manage crypto assets for your company.
Understanding the 0x Protocol and Relayers
At the heart of the 0x ecosystem lies its innovative approach to decentralized trading through relayers.
A relayer functions as a decentralized marketplace that hosts off-chain order books while settling trades on-chain via smart contracts. It connects buyers and sellers without holding custody of funds.
How Order Books Work in 0x
An order book records buy and sell intentions:
- Buy Orders (Bids): Price and amount a buyer is willing to pay
- Sell Orders (Asks): Price and amount a seller is willing to accept
Users create cryptographically signed orders (including asset type, price, quantity, and expiration), which are broadcast across networks. The actual trade execution happens on-chain, ensuring security and transparency.
This hybrid model reduces blockchain congestion by moving non-critical operations off-chain, resulting in lower gas fees and faster processing.

Off-Chain Relaying Explained
The 0x protocol uses off-chain relaying to improve efficiency:
- Users create and sign orders off-chain
- dApps enable price takers to interact with these orders
- Relayers host order books and facilitate discovery
- Smart contracts on Ethereum verify and settle trades
- The underlying blockchain (e.g., Ethereum) finalizes transactions
This structure ensures scalability while maintaining decentralization and security.
Key Features of the 0x Ecosystem
Governance with ZRX Tokens
Holders of ZRX tokens can participate in governance by voting on protocol upgrades, fee models, and treasury allocations. This decentralized decision-making empowers the community and aligns incentives across stakeholders.
Open Source & Developer Tools
Developers can build on 0x using open-source smart contracts. Notable tools include:
- 0x Launch Kit: Quickly deploy custom marketplaces or exchanges
- Asset Swapper & 0x Instant: Embeddable widgets for easy crypto purchases on websites
Projects like Augur, Gnosis, and district0x already leverage 0x infrastructure.
Token Registry
The 0x protocol maintains an on-chain registry of ERC-20 tokens, including metadata like name, symbol, and contract address. This serves as an official reference for verifying tokens and exchange rates.
The ZRX Token: History and Value
Launched in August 2017 via an ICO, 0x raised **$24 million in under 25 hours** by selling 500 million ZRX tokens at $0.07 each. Notably:
- A purchase cap limited early buyers to ~$1,893 worth of tokens
- Aimed at preventing whale dominance and promoting fair distribution
- Over 13,000 unique Ethereum addresses participated
Even at its post-ICO low, ZRX traded at $0.10—50% above the sale price—indicating strong early demand.
Roadmap: What’s Next for 0x?
Governance & Community Development
- Launch of the 0x DAO for decentralized governance
- Establishment of a Protocol Treasury and Constitution
- Governance Portal for voting on proposals
Protocol Upgrades
- Version 3.0 introduces staking capabilities (tested on Kovan)
- Ongoing research into Coordinators for optimized trade execution
- Expansion of ZEIPs (0x Improvement Proposals)
Networked Liquidity
Through 0x Mesh, orders are shared peer-to-peer across relayers, enhancing liquidity without centralized intermediaries.

- Meta-Transactions – Enables gasless trades (“sponsored” transactions)
- Extensive Documentation – Supports rapid development
This makes integrating DeFi functionality into dApps faster and more efficient than ever.
Revenue Model Behind 0x
The protocol sustains itself through multiple streams:
- Trading fees collected on executed swaps
- Staking rewards funded by protocol fees
- API usage fees for commercial developers
- Grant programs funding ecosystem innovation
- Potential future adjustments via governance votes
This creates a self-sustaining economy that rewards participation and innovation.
