How to top up games with crypto, no card: PUBG, Roblox, Mobile Legends, Discord (2026)

You can buy in-game currency and subscriptions with GRAM or USDT — no bank card and no region locks. Pay from your wallet — the code or top-up usually arrives within minutes. Handy where a card won't attach, your region isn't in the store, or you'd rather not expose a card. Below: what's available and how to buy.

Why crypto is more convenient

• No region locks. On-chain payment doesn't depend on your card's country or store account.
• No bank card and no risk of the bank reversing the payment.
• Fast — the code/top-up is issued after the transaction confirms.

What you need first

1. A wallet with GRAM/USDT (Which to choose).
2. A balance — top up with a card via How to buy GRAM.
3. For ID-based top-ups — your game ID/nickname (codes don't need it).

What's available on Catallaxy

• PUBG Mobile UC — in-game UC currency.
• Roblox Robux — Robux.
• Mobile Legends Diamonds (Global) — MLBB diamonds.
• Discord Nitro — Nitro subscription.

How to buy

1. Open the product page you want (links above).
2. Pick a denomination; the GRAM/USDT price is on the card.
3. For ID top-ups, enter your game ID; for a code, nothing is needed.
4. Confirm the payment in your wallet. You get the code/top-up, usually within minutes.

Pitfalls

• Check the ID/server before paying for ID top-ups — delivery goes to exactly what you entered, and mistakes are hard to reverse.
• Product region. Confirm the denomination/region fits your account (e.g. Global vs regional).
• Small buy → GRAM (cheaper), lock the price → USDT (GRAM vs USDT).

FAQ

Can I top up without a card? Yes — crypto only (GRAM/USDT).

Are these codes or ID top-ups? Depends on the product: some are codes (Nitro), some are top-ups by game ID.

Any region limits? Check the card — it states the product's region/server.
