Highlights
Pros
- Trusted by leading Web3 projects including Ledger, Atomic Wallet, Gate.io, CoinEx, and TokenPocket for embedded fiat on-ramp/off-ramp integration.
- EU-licensed as a Virtual Asset Service Provider (VASP) in Lithuania under the Financial Crime Investigation Service and registered as an MSB with FINTRAC in Canada.
- 20+ payment methods accepted including Visa, Mastercard, Apple Pay, Google Pay, SEPA, Open Banking, Pix, and SPEI across 170+ countries.
- 1,000+ cryptocurrencies supported, including major assets like Bitcoin and Ethereum alongside obscure altcoins and meme tokens.
- No account registration required — users can buy, sell, and swap crypto without creating an account, just providing a wallet address and completing KYC.
- Fully non-custodial — purchased crypto is sent directly to the user's personal wallet, so the platform never holds or controls user funds.
Cons
- BestChange removed Guardarian from its listings in November 2022, citing reliability concerns and recommending users avoid the platform.
- Transactions are irreversible once confirmed on the blockchain — sending to an incorrect wallet address means funds cannot be recovered with no recourse available.
- No advanced trading features — lacks spot trading, margin trading, futures, staking, or portfolio management tools available on full-service exchanges.
- No dedicated mobile app — all transactions are done through the web-based platform via a mobile browser, lacking native app functionality.
- Users report cancelled transactions after payment is charged, with refunds taking extended periods to process.
