Cryptocurrency adoption continues to grow, and with it, the demand for secure, user-friendly digital wallets. COINS by CoinPaprika is one such solution—a non-custodial mobile wallet that empowers users to manage their crypto assets with full control and privacy. This guide dives deep into how COINS works, its supported features, security model, and practical use cases, helping both newcomers and experienced users make informed decisions.
What Is a Non-Custodial Wallet?
At the heart of COINS lies the principle of non-custodial ownership. Unlike centralized exchanges or custodial services, where a third party holds your private keys, a non-custodial wallet gives you full control over your funds.

With COINS, your private keys are generated and stored locally on your device. The app never accesses or stores your recovery phrase—meaning only you can access your assets. This aligns with the core philosophy of blockchain: true ownership without intermediaries.

Supported Cryptocurrencies and Storage
COINS supports a wide range of cryptocurrencies, including major assets like Bitcoin (BTC), Ethereum (ETH), Tether (USDT), XRP, and many ERC-20 and BEP-20 tokens. You can store, send, receive, and exchange these directly within the app.
The wallet allows storage of both native coins and compatible tokens. However, if COINS discontinues support for a specific cryptocurrency, your funds remain safe on the blockchain—you’ll just need to import your recovery phrase into another compatible non-custodial wallet to manage them.
Buying Crypto with Fiat Currency
You can purchase crypto using fiat currency (like USD or EUR) through integrated third-party providers:
- MoonPay
- Ramp Network
- Wyre
- Bitcoin Widget (Poland only)
Each provider has its own supported countries, fees, and transaction limits.
Supported Countries for Fiat Purchases
Availability depends on your region:
- MoonPay maintains a list of unsupported countries.
- Ramp supports a broad range of nations; check their official page for details.
- Wyre primarily serves the U.S. and select international markets.

Fees for Fiat-to-Crypto Transactions
Fees vary by provider:
- MoonPay: 6.5% fee, minimum €5.99
- Ramp: 1.99%–4.99%, depending on payment method, minimum €1.49
- Wyre: 4.9% + $0.30 (U.S.), 5.9% + $0.30 (international), minimum $5
- Bitcoin Widget: 10% fee
Blockchain network fees are additional and depend on current congestion.
Daily and Monthly Purchase Limits
Limits are set by each provider:
- MoonPay, Ramp, Wyre, and Bitcoin Widget all enforce KYC-based daily and monthly caps.
- These limits increase with verification level and transaction history.
Always review the provider’s website for up-to-date threshold information before initiating large purchases.
How Secure Is the COINS Wallet?
Security is a top priority. COINS uses industry-standard protections:
- Biometric authentication (fingerprint or face recognition) for all transactions
- Two-factor verification for sensitive actions
- Local storage of private keys—never transmitted or stored on servers
- Recovery phrase (12 or 24 words) that grants full access to your wallet
Since COINS does not store your recovery phrase, losing it means permanent loss of access to your funds.
What Happens If I Lose My Recovery Phrase?
Your recovery phrase is the sole key to your wallet. If lost and no backup exists:
- There is no way to recover your funds
- COINS cannot assist, as they have no access to your private keys
- Assets remain on the blockchain but become inaccessible
✅ Best Practice: Write down your recovery phrase on paper and store it in a secure, offline location. Never share it or take screenshots.
Managing Assets Across Devices
You can restore your wallet on any new device using your recovery phrase.
Steps to recover:
- Install the COINS app on a new phone
- Tap “Restore Wallet” under the My Coins tab
- Enter your 12- or 24-word recovery phrase
As long as the new wallet supports BIP39 standard derivation paths, you can also import your funds into other non-custodial wallets like Trust Wallet or Exodus.
Troubleshooting Common Issues
Why Can’t I See My Funds After Restoring?
Sometimes funds don’t appear due to incompatible address formats. For example:
- Older wallets may not support SegWit (bech32) addresses (
bc1...) - COINS uses native SegWit for lower fees and faster transactions
If restoring in another wallet, ensure it supports SegWit and correct derivation paths.
Why Is My BTC Address Not Accepted Elsewhere?
COINS generates native SegWit (bech32) BTC addresses starting with bc1. Some older platforms only accept legacy (1...) or P2SH-SegWit (3...) formats. While more exchanges are upgrading, compatibility issues still occur.

Why Are 20 XRP Unavailable?
The Ripple network requires a minimum reserve of 20 XRP to activate an account. This amount is locked and cannot be spent—it ensures network stability and prevents spam. To use XRP in COINS, you must deposit at least 20 XRP to meet this requirement.
App Crashes When Using Tether (USDT)?
If the app crashes when interacting with USDT:
- Backup your wallet carefully
- Delete the Tether wallet within the app
- Restore it using your recovery phrase
This often resolves bugs caused by outdated token versions or syncing errors.
Can I Still Access Funds If COINS Shuts Down?
Yes. Because COINS is non-custodial and follows BIP39 standards:
- Your assets exist on public blockchains
- You retain full ownership via your recovery phrase
- You can import your wallet into any BIP39-compatible app at any time
Your crypto is not tied to the app’s existence.
