How to buy Robux with Bitcoin, Ethereum or USDT

You can buy Robux without a card or account using BTC, SOL, native ETH on Ethereum, Base or Arbitrum, BNB on BNB Smart Chain, POL on Polygon, or TRX on Tron. You pay for a Roblox gift card code, we manually verify the transfer, and you redeem the delivered code yourself for Robux.

Why crypto, and why a card

Roblox does not take crypto directly, so the practical route is a gift card paid for with crypto. That keeps your card and bank out of it entirely, puts no payment method on your Roblox account, and needs no sign-up — you just need a wallet with some crypto in it.

The steps

• Choose a Robux gift card and enter the email where your code should go.
• Pick your coin — Bitcoin, Ethereum, USDT or another. The price is set in US dollars and converted to your coin at checkout, so you see the exact amount to send.
• Send exactly the amount shown on the private payment page, using the specified network.
• Submit the public transaction ID. After manual on-chain verification, the code arrives by email and at your private order link.
• Redeem it at roblox.com/redeem for Robux. You redeem it yourself; we never touch your account.

Keep the fee low

The Robux price is the same whichever coin you use — only the blockchain's network fee differs. On a small card, a stablecoin like USDT on a low-fee network usually costs a few cents to send, while Bitcoin can cost a few dollars when the network is busy.
