How to Buy Fight Coins
Pick a coin, send the exact amount to the address we show you, FC are yours in minutes.
1 Fight Coin = $1.00 USD, always. No markup, no conversion games.
Can I pay directly by credit card?
Not directly on Catfight World — we accept cryptocurrency only. But your card is still how most people get there: you use it on a crypto exchange to buy crypto first, then send that crypto here to top up your Fight Coins. It is an extra step the first time, and it only has to be learned once.

Getting your first crypto

1
Choose which crypto to use
For most first-time users we recommend Solana (SOL). It is usually fast, the fees are a fraction of a cent, and it is far better suited to small payments than Bitcoin. Bitcoin works too, but it is slower and its network fees are often several dollars — which is a lot on a $10 top-up.
The most important rule on this page:
The crypto you buy must match the crypto you choose at checkout.
Choose Solana here, send Solana. Choose Ethereum here, send Ethereum. Choose Bitcoin here, send Bitcoin. Do not mix them.
Two of our options also name a network — "USDC on Base" and "USDT on TRON". For those the network has to match as well. If that sounds like one thing too many to keep track of, use Solana: one coin, one network, nothing to line up.

Create an account with a crypto exchange
A crypto exchange is a website or app where you buy cryptocurrency using your debit card, credit card, or bank account. Popular ones include Coinbase, Kraken, Binance and Crypto.com. Availability depends on your country, so pick one that operates where you live.
Most exchanges will ask you to verify your identity. That is normal — they are regulated financial services. You only ever do that with the exchange. Catfight World will never ask you for identity documents to buy Fight Coins.
One thing worth knowing before you pick: some exchanges hold crypto bought with a card for a few days before they will let you send it anywhere. If that happens, nothing has gone wrong and nothing is lost — you simply cannot send until the hold clears. If you would rather not wait, check the exchange's withdrawal-hold policy before you buy.

Buy a little more than you need
Buy the coin you chose in step 1 — and buy slightly more than your top-up amount.
Sending crypto costs a small network fee, and some wallets take that fee out of the amount you send rather than out of the rest of your balance. If you buy exactly $50 and send exactly $50, slightly less than $50 can arrive.
This is not theoretical: it is the single most common reason a top-up lands short, and it happens far more on Bitcoin than on Solana. A dollar or two of headroom avoids it entirely.

Start your top-up on Catfight World
Come back here and go to your wallet, then press Top Up. Choose how many Fight Coins you want, then choose the same cryptocurrency you just bought. Bought Solana? Choose Solana.
Press Continue. Worth knowing: that is the moment the coin is fixed. The payment page opens on an address for the coin you picked and cannot be switched to a different one. Nothing is charged until you actually send, so if you land on the wrong coin, close the page and start again.
-
5
Copy the payment address
The payment page shows you two things: an exact amount to send, and a wallet address.
A crypto wallet address is not a street address, a bank address, or a town. It is a long code made of letters and numbers, something like
J8bg6tNPWA9gH4quVwZm8mbu95HDR5XKxgZftGejY3VB. It tells your exchange where to send the payment. Copy it exactly — do not retype it.You may also see a QR code. It contains the same address. If your exchange lets you scan a QR code, that is often easier and removes any chance of a copy-paste mistake.
-
6
Send the payment from your exchange
Go back to your exchange and find the button for sending crypto out. Different exchanges word it differently — Send, Withdraw, Transfer, Transfer out or Pay out. They all mean the same thing: send to an outside address.
Then: choose the same cryptocurrency you selected at checkout, paste the wallet address, enter the exact amount shown, and confirm.
-
7
Wait for your Fight Coins
Once the payment is confirmed on the crypto network, your Fight Coins are added to your balance automatically. Solana is usually a matter of seconds. Bitcoin can take 15–30 minutes.
You do not need to keep the payment page open. Once the crypto has been sent correctly, the credit happens on our side whether you are watching or not.

Paying with crypto
-
1
On the top-up page, choose how many Fight Coins you want and pick the coin you'll pay with — Solana is the fastest and cheapest, and there is no network to choose.
-
2
Press Continue. This is the point of no return for the coin: our checkout partner opens straight on a payment address for whichever coin you picked, and cannot be switched to another. If you land on the wrong one, close it and start again — nothing is charged until you send.
-
3
Copy the deposit address and the exact amount shown, then send from any wallet or exchange (Coinbase, Binance, Kraken, MetaMask, Phantom — any of them).
-
4
Send the exact amount. Make sure the network fee comes out of your wallet's balance rather than the amount you're sending, or less than you intended will arrive.
-
5
Leave the page open if you can — it watches the blockchain and updates on its own. You don't have to: the credit happens on our side either way.
-
6
Your Fight Coins appear in your balance the moment the network confirms the payment.

Good to Know
Common questions
Can I pay with a credit or debit card?
Not directly here — Catfight World accepts cryptocurrency only. Your card still works, just one step earlier: you use it on a crypto exchange to buy the crypto, then send that crypto to us. The guide above walks through it from scratch.
Which coin is best?
Solana (SOL), and it is not close. You can buy it with a card on almost any exchange, it is one coin on one network — so there is no "which chain?" question to get wrong — and it arrives in seconds for a fraction of a cent in fees. USDC on Base is a good second if you already hold it, though check your exchange actually supports the Base network before withdrawing. Bitcoin and Ethereum work, but both take 15–30 minutes and cost a few dollars in network fees, which is a lot on a $10 top-up.
Can I change coin after I press Continue?
No — that is the moment it is fixed. We hand your choice to the checkout so it opens straight on a payment address for that coin, which saves you working through a list of hundreds. The trade is that the coin cannot be changed on that page. Nothing is charged until you actually send, so if you land on the wrong one, close it and start again from the top-up page.
Do I need my own crypto wallet?
Not necessarily. If you already use an exchange like Coinbase, Binance, or Kraken, that account works perfectly — you send directly from there. If you prefer a self-custody wallet (MetaMask, Phantom, etc.) that also works. You only need a wallet of some kind to hold and send the crypto.
Why does the platform use crypto at all?
It's how we keep the platform open to fight fans worldwide without the restrictions traditional processors place on this kind of content. Whatever coin you pick, the rate is always exactly 1 FC = $1.
What does it cost me?
Just the blockchain network fee — a fraction of a cent on Solana, cents on Base or TRON, a few dollars on Bitcoin or Ethereum mainnet. We never add a markup on top of the FC purchase amount.
How long until my Fight Coins arrive?
Solana: seconds. TRON (TRX or USDT-TRC20): about a minute. USDC on Base: about two minutes. Bitcoin: 15–30 minutes. Ethereum mainnet: 5–15 minutes depending on network traffic.
I closed the tab — did I lose money?
No. If you didn't complete a payment, you weren't charged. If you did pay, your Fight Coins always land even if you closed the tab — the confirmation happens server-side once the network confirms your transaction. The checkout page shows a countdown for how long the invoice stays valid, and any unfinished top-up shows in the Wallet page so you can resume it.
What if I send the wrong amount?
Underpay: we credit you a proportional amount based on what arrived in our wallet — pay for 50 FC but only 80% arrives, you receive 40 FC. Shortfalls under 1% (typical for network-fee rounding) credit in full. Overpay: you get the full requested FC amount. One thing to watch if you are claiming the welcome bonus: it needs at least 10 FC to actually arrive, so if your wallet takes the network fee out of the amount you send rather than out of your balance, a top-up that started above the threshold can land below it. This is far more likely on Bitcoin than on Solana or the stablecoins. If you significantly overpaid by mistake, contact <a href="mailto:hello@catfight.world" class="text-rose-gold hover:underline">hello@catfight.world</a> and we'll sort it out.
Can I send from a hardware wallet?
Yes. Any wallet that can send the coin you chose works — Ledger, Trezor, Trust Wallet, MetaMask, Phantom, exchange withdrawals, all fine. The deposit address shown at checkout is just a standard address for that chain.
